In a herculean effort, Caltech's Bruce Murray Laboratory for Planetary Visualization has created what has now been deemed the most detailed 3D map of Mars ever made.

The Global CTX Mosaic of Mars map comprises more than 110,000 images snapped by NASA's Mars Reconnaissance Orbiter (MRO) black-and-white Context Camera (CTX). Each pixel represents a staggering 270 square feet or 25 square meters, and the entire mosaic image contains 5.7 trillion pixels. NASA writes on its website that if this mosaic image was printed out, it would cover the entire Rose Bowl Stadium in Pasadena, California.

The space agency explains that the new 3D map of the Red Planet took Caltech's Bruce Murray Laboratory for Planetary Visualization took six years to stitch together and tens of thousands of hours to develop. Not to mention the more than 120 peer-reviewed studies and scientific papers that were cited and implemented into its creation. The idea behind the map was to create an interactive experience that allowed anyone to explore the various different regions of Mars.

The strange phenomenon was captured on Monday, March 27, by photographer Valter Binotto, who managed to snap an incredible shot of the red ring that only appeared for a few milliseconds.

Binotto was stationed in the foothills of the Italian Alps when he snapped the above photograph of the phenomenon looming over what appears to be the small Italian town located in northern Italy called Possagno. However, the accurate location of the red ring wasn't above Possagno. Binotto's location when the photograph was taken has caused the image to create a forced perspective, a filming/photography technique that is used to create the visual illusion that objects appear larger, smaller, farther, or closer than they really are.

This technique was abundantly used through Peter Jackson's Lord of the Rings movies to make characters such as Gimli the Dwarf and all the Hobbits appear smaller than they really are. As for the red ring, Spaceweather reports that it's called an ELVE, or an Emissions of Light and Very Low-Frequency Perturbations due to Electromagnetic Pulse Sources.

Astronomers have detected signals from an Earth-sized exoplanet that is just 12 light years away from Earth, according to the results of a new study published in the scientific journal Nature Astronomy.

The exoplanet astronomers have identified is called YZ Ceti b, and it orbits a red dwarf star within the constellation Cetus. NASA notes on its website that this exoplanet is a rocky world that's approximately the size of Earth with a mass of 0.7 Earths. Other notable features of YZ Ceti b are its orbit which is the time it takes for it complete one full rotation around its host star. According to the space agency and the astronomers in their paper, YZ Ceti b only takes two Earth days to complete one orbit of it star.

The team behind the paper detected multiple repeating radio signals from YZ Ceti b, which leads researchers to suggest that this exoplanet may have a magnetic field, and by extension, perhaps an atmosphere. It should be noted that detecting an exoplanet's magnetic fields has proven quite difficult for astronomers, which is unfortunate considering it's a vital element in how life has managed to survive and thrive on Earth.

Scientists have discovered what could be the earliest piece of evidence of a meteorite colliding with Earth billions of years ago.

The group of researchers presented their findings at the 54th Lunar and Planetary Science Conference last week, and according to the team, the meteorite fragments, known as spherules, were drilled out of volcanic and sedimentary rocks called the Dresser Formation of the Pilbara Craton in located Western Australia.

Notably, spherules are formed when a meteorite collides with the surface of the planet, causing vast amounts of rock to be superheated and thrown up into the air, where it is then cooled and hardened. Over the thousands, millions, or even billions of years since the event, these spherules are reduced in size to approximately a pinhead. Despite their size, these small fragments of meteorite hold clues about Earth's distant past and the various cataclysmic events that took place.

Some planets and moons within the cosmos only show one side to their host star, meaning one side of the object is permanently a day side, and the other is permanently a night side.

Suppose that Earth was like this. It would mean one side of the planet is forever the day side, and the other is dark. While this may sound like an apocalyptic scenario, if Earth suddenly shifted into this state, for other planets in the universe where life may exist, this would be normal. According to a new study that explores the possibility of life on these planets, planets that have become tidally locked to their star could have the right ingredients for life to exist at their "terminator zones".

The researchers explain that these terminator zones are the dividing line between the day and night sides of the planet. It should be noted that planets that are tidally locked to their stars usually vary drastically in temperature, with the day side of the planet reaching hundreds or even thousands of degrees in temperature, while the night side is the exact opposite, with temperatures falling into the low minuses. However, researchers suggest that the dividing line between the hot and cold sides of the planet may be the perfect balance of temperature for life, as humans know it, to exist.

New research has been published about a very strange explosion that was detected in 2018. This explosion stunned astronomers when it was discovered, as it was pancake-shaped rather than spherical.

This particular explosion was the very first detected fast blue optical transient (FBOT) explosion, which is currently a grey area for astronomers, as only four others have been detected since the 2018 event officially known as AT2018cow, or the Cow. What is known is that this explosion occurred 180 million light years away from Earth and was approximately the size of the entire solar system.

Additionally, an FBOT explosion behaves very differently when compared to the most typical type of space explosion, a supernova, which happens when a star runs out of its fuel and begins to collapse under its own gravity. A supernova explosion is typically spherical or round, while research suggests that the Cow, or these explosions in general, are more flattened and disk-shaped.

NASA's Double Asteroid Redirection Test (DART) was a success, and according to the space agency, the entire mission was a "great success".

DART was the world's first planetary defense mission, as the objective was to see if it was possible to change the orbit of a binary asteroid system. The target of the mission was the smaller of the two asteroids, Dimorphos, which is orbiting its larger companion asteroid, Didymos. NASA selected this system as it's very well documented by astronomers, with orbits, velocities, and other variables already verified. The goal was to see if a vending machine-sized spacecraft traveling at extremely high speeds was capable of altering the orbit of Dimorphos.

The mission was a smashing success as DART collided with the surface of the 530-foot-wide asteroid Dimorphos on September 26, 2022, and was watched by many space and ground-based telescopes on Earth. In the weeks following the collision, DART researchers began analyzing the data and only recently presented the agreed-upon results at the 8th Planetary Defense Conference in Vienna, Austria, on Monday, April 3.

NASA has revealed the next astronauts that will be returning to the Moon as part of the space agency's Artemis II mission.

The space agency took to all of its social media channels to announce the NASA and Canadian Space Agency (CSA) astronauts that have been chosen for the very first of NASA's crewed missions on the long road to establishing a long-term and sustainable presence on the surface of the Moon. NASA's Artemis I mission was a success, with the space agency's Orion spacecraft even conducting additional observations after completing all of its primary mission objectives.

Much like NASA's Artemis I mission, Artemis II is a reconnaissance mission and won't feature any landing on the surface of the Moon (as Artemis I was uncrewed). Instead of skipping ahead to landing on the Moon, NASA has opted for gathering as much data as possible about the spacecraft's systems, which include its sensors, instruments, temperatures, communications, cameras, and more. All of this data is used to make lunar trips safer and more efficient for astronauts. Artemis II will be NASA's first crewed mission back to the Moon in more than 50 years.

Researchers have created a new map of Mars that shows off the Red Planet's geological features in incredible detail.

The new Martian map was created using data obtained by the Emirates Mars Mission (EMM), also known as Hope, operated by the United Arab Emirates (UAE) Space Agency. UAE researchers teamed up with scientists from New York University Abu Dhabi to create the map, which showcases what EMM's onboard imaging system called the Emirates Exploration Imager (EXI), sees while it orbits the Red Planet. The map consists of more than 3,000 individual observations of Mars that were snapped over the course of one Mars year, which is two years on Earth.

These thousands of images were then carefully stitched together by researchers, color corrected, and polished. The final resulting map, as seen below, showcases many of Mars' sought-after geological features, such as the remnants of ancient river systems coursing across the Martian surface, lakes that have long since dried up in the harsh climate but may contain traces of ancient microbial life, valleys that likely contained water some 3.5 billion years ago, and the planet's polar ice caps.

The depth record for filming a fish at the lowest depth possible has been shattered as researchers have caught a specific type of snailfish at a depth of 27,349 feet.

The discovery was made off the coast of Japan within the Izu-Ogasawara Trench, where researchers dropped an autonomous lander to the extreme depths of the trench. Notably, the previous record holder for the deepest observation of a fish was achieved in Marina Trench in 2018 at a depth of 26,830 feet. The new record holder beat the previous record holder by 518 feet, and according to reports, its not likely to be broken, or if it does, it won't be by much, as the researchers believe this fish was swimming at the border between where fish are able to survive and where they are not.

Research from around the world confirmed a prediction made by Professor Alan Jamieson of the University of Western Australia, known for pioneering the study of life at the deepest places in the ocean and exploration. Jamieson said 10 years ago that life deep sea life would exist between 26,902 and 27,559 feet. Depths below this range won't harbor any fish but more so likely smaller microorganisms of life.

Images snapped by NASA and the European Space Agency's (ESA) Hubble Space Telescope have led to the discovery of what could be the biggest black hole known to date.

The team of astronomers analyzed images snapped of the Abell 1201 galaxy cluster by the Hubble Space Telescope and, from those images, used gravitational lensing to magnify the background objects. Notably, gravitational lensing is a phenomenon that occurs when the gravity of an object bends the light that is passing through it, causing a magnification effect. Astronomers commonly use this natural phenomenon to see much further into the cosmos than they could if they were exclusively using human-made telescopes such as Hubble.

Using gravitational lensing, astronomers were able to spot the giant black hole in the background of one of Hubble's images. According to statements from the astronomers, this black hole has an estimated mass of approximately 30 billion suns and is one of, if not the largest black hole ever discovered. Astronomers made these conclusions after simulating how much light was bending around the foreground galaxy and analyzing the gravitational lensing magnification. Before arriving at their conclusion, researchers tested the size of thousands of black holes and eventually found a solution to what they were observing.

Hubble has snapped a new image that has recently been released of a mysterious object located approximately 390 million light years away from Earth. This object is called Z 229-15.

Z 229-15 resides in the constellation Lyra, and according to a blog post by the European Space Agency (ESA), the more researchers look into Z 229-15, the more difficult it becomes to classify it. According to the blog post, Z 229-15 falls into a special category of celestial object that fits multiple definitions at once. As the ESA writes, researchers have classified Z 229-15 as a galaxy but also an AGN, an active galactic nucleus. A galaxy is given this classification when it harbors an active supermassive black hole at the galaxy's center.

The powerful gravitational pull of the supermassive black hole pulls large amounts of matter toward it, forming a disk around the black hole that emits a bright light across the electromagnetic spectrum when it's heated up. The definitions or classifications don't stop there, as Z 229-15's AGN is also a quasar, which astronomers label as a specific subtype of AGN, that is only given to a galaxy when it displays an extreme level of brightness over a very long distance. Since Z 229-15 is located 390 million light-years away from Earth and Hubble's image showcases an extremely bright center, Z 229-15 fits this classification also.

NASA has taken to its blog to announce that a study has been conducted on what is being described as the "brightest of all time" explosion that recently hit the solar system.

The space agency writes that on October 9, 2022, a pulse of intense radiation known as a gamma-ray burst (GRB) passed through the solar system and that this wave, which is known as the most powerful type of explosion in the universe, blinded NASA's eyes in space. NASA writes that the event named GRB 221009A was so bright that it effectively blinded most gamma-ray instruments in space, which means that NASA was unable to detect the true intensity of the explosion.

However, the space agency says that researchers were able to reconstruct the data from NASA's Fermi Gamma-ray Space Telescope and compared their results against data being worked on by teams of researchers in China and Russia. NASA writes that research suggests an event such as this occurs once in every 10,000 years and that it was 70 times brighter than any other GRB humans have detected yet. So, where did it come from?

In June, a gold miner made a shocking discovery in Yukon, Canada, as the digger found the remains of a woolly baby mammoth incased in permafrost.

This woolly baby mammoth is one of many mammoths that have been found encased in permafrost, which has preserved their skin, fur, and tissue for thousands of years. From these carcasses, researchers are able to extract the DNA sequence of the mammoth, which can then be combined with other animal DNA sequences. Australian cultured meat startup, Vow, did this very thing, with the company announcing the creation of woolly mammoth meatballs, made using the DNA sequence of one of the biggest animals to walk the Earth.

A new report from CNN has revealed the team made the meatballs as a publicity stunt to draw attention to the potential of lab-grown or cultured meat, and it is a cruelty-free alternative to typically sourced meat. The idea behind the implementation of the mammoth meatballs is more symbolic, if anything, as its creators want it to be viewed as an important part of the wildlife that has been lost and for humans to reconsider how they are sourcing their food.

Residents across Florida were shocked to witness a group of fireballs streaking across the night sky on Thursday, March 23, 2023.

The event stunned onlookers as they witnessed what began with a single fireball breaking up into multiple fireballs that burned through the night sky until they went out. Immediately a slew of videos and images made their rounds on social media, joined by rampant speculation about what the fireballs could be. The American Meteor Society (AMS) confirmed the existence of the fireballs and corrected the definition, writing the object "was not a fireball", which is a space rock falling to Earth, but a rocket that was re-entering Earth's atmosphere.

The AMS stated on its website that the object was most likely the KZ-1A rocket 4th stage that launched from China on March 22, 2023. This rocket was designed to launch and deploy satellites in Earth's orbit, but only a day before the fiery sightings it made a post-deployment burn that led it to an uncontrolled reentry over Florida just 24 hours later, according to Jonathan McDowell, an astrophysicist at Harvard-Smithsonian Center for Astrophysics.

Humans know there is water on the Moon, but how much exactly is completely up for debate. New research suggests there is much more than we first anticipated.

Originally humans believed the Moon was a dry, desolate place, but samples obtained by NASA's Apollo mission revealed to scientists tiny microscopic glass beads that form when pieces of space rock collide with the surface of another object. After the impact, these beads rapidly cool and preserve their contents which researchers examined. The beads contained hydration signatures, which were created, in part, with help from the Sun as the solar wind containing hydrogen ions combines with oxygen that's within the lunar soil.

So, here's what the newest research suggests. Solar wind battering the surface of the Sun is combining hydrogen ions with oxygen already present within the lunar soil. The impact glass can store this water, with researchers estimating that each glass bead is capable of holding up to 2,000 micrograms of water, or 0.002 grams of water, for every gram of the particle's mass. Notably, the researchers continued to explain within their study that evidence garnered from hydration analysis suggests that these impact beads can accumulate water over just a few years.

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 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.

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.

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.
