Massive hole appears on the Sun as Earth braces for strong solar wind impact
In what appears to be the second giant hole appearing on the Sun, scientists have reported that Earth may be smacked by a stream of solar wind traveling as fast as 1.8 million miles per hour.
The discovery of the Sun's new hole, which is more accurately defined as a coronal hole, comes after the discovery of an extremely large coronal hole that's estimated to be 30 times the size of Earth. For reference, the newest hole is estimated to be anywhere between 18 and 20 Earths in diameter. Notably, the larger of the two holes has already begun rotating away from Earth, while the smaller, recently discovered coronal hole has come into view, leading researchers to warn that Earth may be struck with a stream of solar wind pouring out of the Sun.
Researchers write that the potential stream of solar wind, which is expected to hit Earth by Friday or Saturday morning, won't damage any human infrastructure but may cause auroras to appear closer to the equator, where sightings are much more rare. For those that don't know, coronal holes release streams of solar wind into space, and while they are quite common, they don't typically appear near the Sun's equator, as these ones have.
Earth unexpectedly rocked by the most intense blast from the Sun in 6 years
Earth was just smacked with a very powerful blast from the Sun that caused the spawning of auroras more south than they typically appear.
The event occurred on March 25 and was confirmed by the U.S. National Oceanic and Atmospheric Administration (NOAA), which issued a statement declaring a severe geomagnetic storm warning and an image showing where the impact would be focused. NOAA's map of Earth shows a large swath of North America being right in the impact zone, which coincides with the plethora of gorgeous aurora images that were posted online during and following the storm.
NOAA ranked the solar storm at G4 on the 5-grade scale that is used to define the intensity of a geomagnetic storm. Notably, the impact of the storm was so strong that there were reports of the Northern Lights appearing as far south as New Mexico in the U.S. So, how does this happen? Auroras such as the Northern and Southern Lights typically appear close to the Earth's poles as the planet's magnetic field deflects charged particles around the planet to its poles, where they reach the weakest points of Earth's magnetic field.
Stunning photos show Northern Lights making a rare appearance south
The Northern Lights, commonly spotted in the Arctic, made its way as far south as Arizona last night, stunning onlookers that happened to catch a glance at the rare sighting.
Over March 23 and March 24, Earth was rocked with an unexpected Coronal Magnetic Ejection (CME) from an eruption that occurred on the Sun. The National Oceanic And Atmospheric Administration (NOAA) issued a warning for G4 (severe) geomagnetic storms across the entire North American region, writing in its warning that the following pieces of technology may be affected; power grids, spacecraft operations, atmospheric drag on satellites operating in Low Earth Orbit (LEO) and GPS operations.
Spaceweather.com reports that as of March 25, the origin of the unexpected CME blast remains unknown, but their suspicions lie with the near-miss March 23 CME that may have caused a ripple effect that hit Earth. With the impact of the CME comes auroras as the charged particles from the Sun interact with Earth's atmosphere and magnetic field, causing the incredible phenomena we call auroras. Auroras typically occur close to Earth's poles, but during a geomagnetic storm, the phenomena can move closer to Earth's equator.

ChatGPT is instructing a man on how to run a business with just a $100 budget
Jackson Greathouse Fall, a brand designer, has created the Hustle GPT challenge, where he acts as an instrument to the instructions of ChatGPT on how to start a business with just $100.
Fall explains in a now-viral Twitter thread that he told ChatGPT that it was now called "HustleGPT" and that it's an "entrepreneurial" artificial intelligence that's goal is to take the initial $100 budget and turn it into as much money as possible within the shortest timeframe possible. Fall added some needed caveats to the prompt, informing ChatGPT that it wasn't able to provide any methods that would involve doing anything illegal and that Fall was going to "act as a liaison" between the AI and the required physical work.
Additionally, HustleGPT was told by Fall that it would do "everything" it says and that he would update the AI on the current cash total of the business as time went on. Following that prompt, Fall explained that HustleGPT told him to set up an affiliate marketing site that makes content around eco-friendly/sustainable living products. HustleGPT provided the steps on how to get started with this business, instructing Fall to buy a domain, hosting, leveraging social media to acquire leads, website design, and optimizing for search engines. Notably, HustleGPT provided the costs for each of the steps and the grand total spent.
NASA's Webb telescope spots first dust storm on planet outside the solar system
Researchers have honed the very sensitive instruments equipped to the James Webb Space Telescope on a planet in a distant star system, gathering data that informs researchers on the conditions of the planet.
The lucky planet to be a target of the highly advanced James Webb Space Telescope (JWST) is an exoplanet called VHS 1256 b, which researchers explain in a recent press release, is a massive brown dwarf planet that's located approximately 40 light-years away from Earth and orbits, not one, but two stars over a 10,000-year period. The researchers explain that VHS 1256 b orbits its stars four times further than Pluto orbits our Sun.
This aspect of VHS 1256 b makes it a prime target for Webb as the light from the planet isn't getting mixed up with the star it's orbiting, allowing Webb to gather a much more accurate reading. According to the press release, the higher altitudes of VHS 1256 b's atmosphere reach temperatures of 1,500 degrees Fahrenheit, and within those clouds, Webb detected both large and small silicate dust grains. The smaller grains are comparable to the size of tiny particles that appear in smoke, and the larger grains are similar to extremely hot grains of sand.
Here's why the next moon-walking astronauts won't be wearing a black spacesuit
NASA partner Axiom Space has revealed its next-generation spacesuit scheduled to be the safety barrier between the harsh lunar landscape and the NASA astronauts that will be walking on its surface.
NASA's Artemis 3 mission, scheduled to launch in December 2025, plans on sending the first astronauts back to the lunar surface in 50 years, and those astronauts will be wearing Axiom Space's Exploration Extravehicular Mobility Unit (xEMU). This next-generation spacesuit was developed under NASA's Exploration Extravehicular Activity Services, or xEVAS, contract, which also includes Collins Aerospace, which will be developing its own spacesuit that'll replace the current suits used by astronauts on the International Space Station (ISS).
As I explained in my previous article about these spacesuits, on March 15, Axiom Space revealed its first iteration of the new spacesuit design by having someone walk out on stage wearing it. The new suit comes with a range of improvements compared to Apollo spacesuits, which have been mostly the same for more than 40 years.
200-foot-wide asteroid closes in on Earth, will pass closer than the Moon
Scientists have discovered an asteroid that's anticipated to pass closer than the Moon is to Earth in the next few days.
A new article published in EarthSky details a member of the Apollo family of asteroids, 2023 DZ2, which researchers estimate to be approximately 210 feet in diameter. The article states that the asteroid doesn't pose any threat to Earth and will make its closest approach to our planet at around 3:51 p.m. EDT on March 25. The space rock was discovered by astronomers at the observatory La Palma, in the Canary Islands, Spain, on February 2023.
As previously stated, astronomers expect the 210-foot-wide asteroid, which is approximately the of an average skyscraper, will pass between Earth and the Moon, which, given the asteroid's close proximity, enables amateur astronomers to catch a viewing. Notably, 2023 DZ2 is classified as a Near Earth Object (NEO) and orbits the Sun every 3.16 years. In the past, the large asteroid was thought to pose a risk to Earth, with estimations putting Earth on a collision course with it on March 27, 2026. However, after further analysis, officials removed 2023 DZ2 from the Sentry Risk Table.
NASA's Mars helicopter completes another flight, closing in on big milestone
NASA's Mars helicopter has proved time and time again that flight on the Red Planet is possible, and now Ingenuity is closing in on a historic milestone.
Ingenuity landed on Mars with its companion rover, Perseverance, in February 2021, and just two months later, in April, the small aircraft became the very first machine to achieve powered flight in the skies of a planet that isn't Earth. NASA engineers sent Ingenuity to Mars as a technology demonstration. The objective was to see if an aircraft was able to fly on Mars, a planet that has an atmosphere very different from Earth. Notably, Mars' atmosphere is 1% as thick as Earth's, meaning to achieve flight, the aircraft would have to spin its blades much faster than a typical helicopter.
The problem of a thin atmosphere was anticipated by NASA engineers, and the appropriate design changes were made. Ingenuity features special counter-rotating blades that spin at approximately 2,500 revolutions per minute (RPM). For context, a typical helicopter spins its blade at just 400 to 500 RPM to maintain flight. This difference between RPM illustrates the severe difference in flight on Earth and flight on Mars.
US nuclear power plant admits it leaked 400,000 gallons of contaminated water
An energy giant that manages the nuclear power plant in the city of Monticello, Minnesota, has confirmed that 400,000 gallons of contaminated water has leaked out of its nuclear power plant.
Reports indicate the leak was initially detected by the Monticello nuclear power plant four months ago, in November 2022, and was reported immediately to state and federal regulators. However, it wasn't until last week that the public was made aware of the situation. Xcel Energy, the energy giant that runs the Monticello nuclear power plant, issued a press release where it states that it took "swift action" to contain the leak to the plant site and that the contaminated water is "fully contained on-site".
Notably, the press release states the leak poses no health or safety risk to the local community or environment and hasn't been detected beyond the facility itself, which, according to Xcel Energy, means it hasn't been detected in any local drinking water. As for the water, Xcel Energy confirmed that the 400,000 gallons contained tritium, a naturally occurring form of hydrogen that emits a weak form of radiation. Tritium can't travel long distances in the air or penetrate the skin, according to officials with the federal Nuclear Regulatory Commission (NRC).
Unidentified fiery objects caught on video streaking across the night sky
Northern California skywatchers were shocked to see a group of fiery objects enter Earth's atmosphere and illuminate the night sky, but an explanation has been put forward about their origin.
Residents in the area, and as spotted by Aaron, who took to his personal Twitter account with the above video, saw the group of objects on Friday night when they began burning across the night sky. Aaron, like many of the residents that saw the event, was confused about its origin, suggesting that it could be a meteorite breaking up throughout its entry, aliens, or even China. None of these suggestions ended up being accurate, but they are warranted considering the slew of UFO detection in North American airspace over the past several weeks.
As you can probably imagine, between the time of the sighting and the explanation being posted online there was rampant speculation about the origin of the objects. Some individuals wrote that it was a meteor shower, while others suggested it was space debris, such as a defunct satellite reentering Earth's atmosphere. The latter was closer to the truth, as outlined by Jonathan McDowell, a renowned astrophysicist at the Harvard-Smithsonian Center for Astrophysics, who took to Twitter with an in-depth explanation that points to space junk that was jettisoned from the International Space Station (ISS).
Solar tornado the size of 14 stacked Earths captured on video by NASA
Astronomers from around the world have had their instruments pointed at the solar tornado that has been unfurling on the surface of the Sun for the past week.
The above gif showcases the scientifically popular solar tornado, which is a twisted filament of boiling hot plasma that is expanding further and further away from the surface of our star. For three days, the tornado continued to expand, with reports stating that it grew to an astonishing height of 75,000 miles, which is about the same as fourteen Earths stacked on top of each other.
According to astrophotographer Andrew McCarthy, who took to Twitter on March 18, the day the solar tornado was at its highest, and said, "This 14-Earths-tall swirling column of plasma was raining moon-sized gobs of incandescent material on the sun". Furthermore, Apollo Lasky of Naperville, Illinois, who made the above gif using images from NASA's Solar Dynamics Observatory, said the solar tornado was occurring near the Sun's North Pole and grew for a total of three days before it came back down to the Sun's surface.

UK government to send Rolls-Royce branded nuclear reactor to the Moon
The United Kingdom is preparing to develop a Moon base that will enable humans to work and live on the lunar surface, and the UK government wants Rolls-Royce to power it.
A new press release from the UK Space Agency details a new injection of funding into the Micro-Reactor program run by Rolls-Royce. This program is aimed at developing technology that will enable a sustained presence on the surface of the Moon through the generation of nuclear power. According to the press release, nuclear power has the potential to extend Lunar missions and thus the scientific potential, hence the UK Space Agency announcing 2.9 million pounds ($3,555,124 USD) in new funding for the project.
Notably, the new round of funding received by the UK Space Agency is for the initial demonstration of a UK lunar modular nuclear reactor, which is expected to be relatively small and lightweight compared to other power systems. Furthermore, a small nuclear reactor that can ideally be carried around by a single human could act as a continuous power source regardless of the environmental conditions. Rolls-Royce will be joined by other collaborators on the project, such as engineers from the University of Oxford, University of Bangor, University of Brighton, University of Sheffield's Advanced Manufacturing Research Centre (AMRC), and Nuclear AMRC.

Hubble shocks all eyes with new jaw-dropping image of the cosmos
NASA has taken to its blog to share a new image captured by the famous Hubble Space Telescope, which honed its sensitive instruments on the globular star cluster known as Messier 55.
NASA took to its social channels to share the image and explained that Messier 55 (M55) is a loosely concentrated globular cluster that's located approximately 20,000 light years away from Earth within the constellation Sagittarius. The above image snapped by Hubble shows just a portion of M55, which stretches some 100 light years and contains an estimated 100,000 stars of 55 various types and brightness. The large collection of stars forms a spherical shape that can be traced back to the intense gravitational pull of each of the stars.
Notably, ground-based telescopes struggle to observe globular clusters such as M55 as they are hindered by light pollution. Hubble's safe position in low Earth orbit, above Earth's atmosphere, allows for the space telescope and, by extension, astronomers and scientists, to capture the globular cluster in all its glory, leading to a deeper understanding of the globular cluster itself and the stars that it contains. In particular, astronomers are interested in learning more about the evolution of stars by studying globular clusters, as the knowledge gained will translate to the star we call the Sun.

You can thank Apple for NASA's stunning new spacesuit
You've probably already seen that rather fancy new NASA EVA spacesuit that's been doing the rounds over the last couple of days. But did you know that you actually have Apple TV+ to thank for its design?
That's because the costume designer behind the excellent For All Mankind on Apple TV+ was involved in coming up with the design for that spacesuit. And we can probably all agree that they did a bang-up job with it, too.
Costume designer Esther Marquis was the person behind both For All Mankind's fictional spacesuits and this new, very real, NASA offering. The design consists of three main colors including black, blue, and orange, and doesn't quite look like anything out of the hit Apple TV+ show.

Astrophotographer captures 60,000-mile-high plasma wall falling down on the Sun
A photograph snapped by Eduardo Schaberger Poupeau, an astrophotographer located near Rafaela in Argentina has captured the moment a 60,000-mile-high wall of fire fell down on the surface of the Sun.
The above image of the event was captured on March 9 and required the use of specialized camera equipment. Speaking to Spaceweather.com, Poupeau explained that the wall of hot plasma rose approximately 62,000 miles, which, for context, would be the same height as Earth stacked on top of itself eight times, then fell back down to the surface of the Sun.
Notably, this event is officially called a polar crown prominence (PCP), which is essentially loops of plasma being ejected from the surface of the Sun by contortions in the Sun's magnetic field. Furthermore, since PCPs occur near the poles of the Sun, where there is a stronger magnetic field, these plasma ejections often are pulled back into the Sun. This process of ejection and then retraction has earned the nickname "plasma waterfalls".
Pentagon officials say alien mothership in our solar system may probe Earth
A draft research report by the Pentagon and a distinguished Harvard University professor outlines the possibility of an alien mothership within the solar system.
A new report penned by Sean Kirkpatrick, the director of the Pentagon's All-Domain Anomaly Resolution Office (AARO), and Abraham Loeb, chairman of Harvard University's astronomy department and theoretical physicist, was released on March 7 and focused on the possibility of an artificial interstellar object being present within the solar system and probing the planets within it.
According to the report, there is a possibility of an artificial interstellar object being a "parent craft" or a mothership that sends small probes down to planets, similar to a mission conducted by NASA and other space agencies. This mothership is suspected of being controlled by an artificial intelligence that has likely been dormant for many years as the craft traveled across the universe.
Spacesuit prototype revealed for NASA astronauts landing on the Moon
Axiom Space scored the NASA contract to construct the next generation of spacesuits that will be worn by astronauts returning to the lunar surface.
NASA astronauts will be touching down on the lunar surface as part of the space agency's Artemis 3 mission, and according to a recent press release, Axiom Space will be the company providing the new spacesuits that are expected to come with a variety of different improvements. Axiom Space's website details the new suit called the Axiom Extravehicular Mobility Unit (AxEMU), which a prototype was recently unveiled at Space Center Houston's Moon 2 Mars Festival on March 15.
Axiom Space announced that it will be able to provide NASA with a fleet of training spacesuits by the end of this coming summer, and these spacesuits accommodate a large variety of crew members. Notably, Axiom Space took NASA's traditional spacesuit design, the Exploration Extravehicular Mobility Unit (xEMU), and added increased flexibility, greater protection to withstand the harsh environment of the moon, and the ability to add scientific tools for astronauts to carry out scientific operations while on the surface of the moon.

Red Bull pilot lands plane on top of one of the tallest buildings in the world
Landing a plane is no walk in the park, it presents unique challenges that individuals must train rigorously for, but what if you wanted to land a plane on the world's shortest runway that's stationed atop one of the world's tallest buildings?
That is what pilot Luke Czepiela attempted this week as part of a stunt under the banner of Red Bull, which set up a small helipad on top of the Burj Al Arab Jumeirah, a luxury hotel in Dubai. The above video showcases the small diameter of the landing runway, which only stretched 88 feet from one side to the other. Notably, the helipad was 695 feet above the ground, making Czepiela's room for error even smaller.
According to the pilot, the stunt was practiced approximately 650 times on a normal runway that had a circle painted on the tarmac with the same dimensions as the helipad. It wasn't just practice that needed to be done before the flight, as Czepiela's team was required to modify the plane in order for it to stop within 88 feet of the runway. Engineers removed any unnecessary weight from the planet, which introduced its own problems with wind speed and "precise speed".
NASA rover captures amazing video of a helicopter flying on Mars
NASA's Mars rover, which has been stationed on the Red Planet since February 2021, has captured an amazing video of the Ingenuity helicopter taking flight.
NASA has taken to its blog to provide an update on the recent flight conducted by its Ingenuity helicopter, and according to the space agency, the Mars helicopter has now successfully carried out its 47th flight, achieving a maximum altitude of 39 feet, a top speed of 11.9 mph and 1,444 feet traveled. The flight was captured by NASA's Perseverance rover, which was positioned 394 feet away from the helicopter. As shown by the above video, Perseverance captured Ingenuity taking off, causing a small martian dust cloud to form from its spinning rotors.
Notably, Perseverance captured this footage with its Mastcam-Z imager on March 9, 2023, and according to NASA, the goal of the flight was to reposition the helicopter while also scouting ahead for any viable scientific prospects that Perseverance would then further inspect. For those that don't know, NASA originally sent Ingenuity to Mars with one objective in mind - to see if it was possible to conduct one flight on the surface of the Red Planet. Ingenuity is a technology demonstration that has superseded expectations, with reports stating the helicopter remains in good health on its road to reaching its 50th flight.

International Space Station forced to fire thrusters to dodge object
It was only last week that I reported on the International Space Station (ISS) being forced to fire up its thrusters to dodge a potential collision with a satellite.
NASA confirmed the news of the ISS maneuver via its blog on March 6 and explained that the floating laboratory was at risk of colliding with a satellite that was later discovered to be a commercial Earth-imaging satellite. This maneuver required officials to engage the thrusters on the Progress 83 resupply vessel, raising the orbit of the entire outpost so the satellite could safely pass underneath. The ISS conducted these maneuvers successfully.
According to a report from Roscosmos, Russia's own version of NASA, the ISS had to perform a similar maneuver on March 14 involving the same resupply vessel, Progress 83. Russia's space agency writes that Progress 83 fired its thrusters for 183 seconds to raise the altitude of the ISS to an average of 230 miles above the surface of Earth. Notably, the maneuver that was performed on March 6 required the resupply vessel thrusters to be fired for approximately six minutes.
