Officials at NOAA's Space Weather Prediction Center (SWPC) confirmed on June 8 the Sun released a record-breaking solar flare that was the most intense flare released in the last seven years.

Researchers that conduct round-the-clock tracking of our local star confirmed the solar flare came from sunspot region AR3664, which was calculated to be an M9.7-class solar clare, the second strongest type on the solar flare classification scale. For those that don't know, solar flares are massive, intense bursts of electromagnetic radiation that are a result of the Sun's ever-chaging magnetic field contorting, twisting and snapping.

The blast can cause an impact on Earth, resulting in space launch's being postponed due to the charged particles hitting Earth's atmosphere and widespread radio communication blackouts. Additionally, a solar flare is typically followed by a cornal mass ejection (CME), a wave of charged particles released by the Sun that can cause geomagnetic storms.

Robot dogs carrying guns is real, and there are videos posted of these new war machines being tested for upcoming combat missions.

What a time to be alive - quadruped robotic dogs with rifles strapped to their backs is actually something that is a real life thing. The first reports of such a creation come from Agence France-Presse, who covered a video published by state-owned broadcaster China Central Television (CCTV), which showed Chinese military testing a weaponized robotic dog in various scenarios. The rifle-equipped robotic pooch was shown hopping, diving, leading teams on reconnaissance objectives, and repeatedly firing its rifle attached to its back.

The robotic gun-wielding dogs were created with Unitree's $2,800 Go2 models, which are capable of being active on their own from anywhere between two and four hours depending on the task. The CCTV video shows a Chinese military soldier explaining the new robodogs "can serve as a new member in our urban combat operations" and are capable of "replacing our members to conduct reconnaissance and identify [the] enemy and strike the target."

The world's first biprocessor has been created using human brain tissue, according to Swiss startup FinalSpark that recently published their results.

The company has claimed the bioprocessor is connected to an online platform that enables remote access to 16 human brain organoids. The startup says its neuroplatform is a first-of-its-link and can deliver access to biological neurons in vitro.

Notably, the company claims its new bioprocessor requires 1 million times less power than a traditional processor, and if the startup's claims are proven to be true, these bioprocessors could revolutionize heavy usage processing situations where power is a problem. An example of this would be training large language models, the underpinning technology powering AI.

SpaceX, in a significant move, has announced its fourth Starship launch scheduled for June 5, pending regulatory approval from the Federal Aviation Administration (FAA). This launch marks another milestone in the company's ambitious space exploration journey.

Starship has been launched three times, and each of those launches had the main mission objective of reaching orbit. SpaceX managed to reach orbit on its last launch, along with the separation between the Super Heavy booster and Starship. With that goal out of the way, the Elon Musk-led company is switching its focus to arguably the most important part of Starship, getting it back on the ground safely and undamaged to enable reliable reusability.

Given the immersive size of Starship, 400-feet in total, it's not going to be easy to land the world's largest rocket. Before any land-based attempts are made, SpaceX will first gather its bearings over the ocean. Once it's happy there, it will move to rocket launch pads at its facilities.

The next installment in the DOOM franchise is purportedly called "DOOM: The Dark Ages," and it will be revealed at the Xbox Games Showcase on June 9, according to a new report from Insider Gaming.

The new report comes after previous rumors that ID Software was preparing to reveal its next DOOM project at the Xbox Games Showcase, but at the time of those reports the new DOOM project was under the codename Year Zero. Insider Gaming has now revealed the name for title, writing it has been in development for at least four years and will take players to a "medieval inspired doom world".

The exclusive report mentions the new title could be taking players back to a much younger Doomslayer, perhaps a prequel story about his earlier life before all the blood, dust and glory. Insider Gaming writes that it can independently verify the rumors that the next DOOM game will be unveiled at the upcoming Xbox Showcase.

US government officials have said that Russia's recent rocket launch deployed a payload that is likely a classified space weapon capable of destroying satellites.

The warning comes from Robert Wood, the deputy US ambassador to the United Nations, who said last week Russia conducted a rocket launch, specifically on May 16, when it launched a satellite into low-Earth orbit that the United States has now assessed. According to Wood, the US has reason to believe the payload deployment is likely a counter-space weapon, and it's location is the "same orbit as a US government satellite".

More specifically, the Soyuz rocket's Fregat upper stage released Kosmos 2576 (the payload) into orbit approximately 275 miles above Earth at an inclination of 97.25 degrees to the equator. Notably, Russia's deputy foreign minister, Sergei Ryabkov, said the US's assessment of the payload is "fake news", but didn't provide any clarifying information.

SpaceX is currently undergoing rigorous testing of its Raptor rocket engines, which will be used by the company's next-generation rocket, Starship, the world's largest and most powerful rocket.

The Elon Musk-led company has been conducting research and development on its Raptor engines for quite some time now, and it appears to still be in the midst of tweaking and changing the engine design ahead of the highly anticipated fourth launch of Starship. According to a livestream of SpaceX's McGregor, Texas testing facility by NASASpaceFlight, a Raptor engine recently experienced an anomaly that resulted in an initial explosion and a secondary explosion.

The publication reports the secondary explosion on the test stand can be attributed to the vapors in the air from the first explosion. SpaceX hasn't officially offered any update on the explosion, and given how familiar SpaceX is with exploding rocket-related creations, it can safely assumed no one was injured from this explosion. For those that don't know, SpaceX's flagship rocket, Starship, uses 33 Raptor engines in its first stage booster called Super Heavy.

A stunning meteor passed through the night sky at speeds of more than 100,000 miles per hour, causing a bright flash of blue-green light.

Skywatchers over parts of Spain and Portugal were reminded of the incredible beauty of the cosmos when an asteroid entered Earth's atmosphere at extreme speeds. The European Space Agency (ESA) confirmed the space rock was traveling at around 27.96 miles per second, and the space rock was actually a small piece of a comet. Additionally, the space agency said the chances of finding fragments of the astronomical object was very low as it likely burned up over the Atlantic ocean at an altitude of 37 miles.

What is most impressive about the comet fragment is how streaked across the sky, with the Scientists at the CSIC (Spanish National Research Council) estimate the fireball covered more than 310.69 miles before "going extinct". The event was captured by many people in both Spain and Portugal, and has since gone viral on social media as hundreds of videos were posted showing incredible light display from various locations.

New research from the University of New Mexico has confirmed that microplastics have now been found within human testicle tissue.

A team of scientists analyzed testicular tissue taken from both dogs and humans and found microplastics in every sample. More shockingly, the human testicle tissue had a presence of microplastics three times higher than what was found in the dog testicle tissue. More specifically, the team discovered an average of 122.63 micrograms of microplastics per gram of tissue in canines, while human tissue was 329.44 micrograms.

The discovery of microplastics entering the male reproductive system has raised concerns about its presence impacting fertility, particularly after the team found canine samples that contained a higher quantity of polyvinyl chloride, correlated with lower sperm count in dogs. The team was unable to test the impact of polyvinyl chloride in the human tissue samples.

Astronomers published a new study in the scientific journal Nature Astronomy detailing the discovery of an exoplanet called SPECULOOS-3 b.

The newly found exoplanet is approximately 55 light-years away from Earth, which is in the world of astronomy is extremely close to our planet, given the vastness of the Milky Way. SPECULOOS-3 b orbits its host star once every 17 hours, and astronomers expect that its also tidally locked, meaning one side of the planet is perpetually being blasted by host stars light, while the other side is stuck in perpetual cold darkness.

Due to its proximity to its host star, SPECULOOS-3 b is being bathed in high amounts of radiation, peeling away any form of atmosphere the planet may have had at one stage. The lack of atmosphere and the impossibility of hosting water due to its extreme temperatures make SPECULOOS-3 b inhospitable to life as we know it, but that isn't why astronomers are excited about it.

A group of scientists have managed to thaw frozen human brain tissue without causing any damage to the tissue itself.

The new research is coming out of the Fudan University in Shanghai, China, where a team led by Zhicheng Shao grew self-organizing brain samples that are called organoids. These organoids are grown from embryonic stem cells and take three weeks to fully mature. Once fully mature the brain tissue has developed neurons and neural stem cells, which means they are ready for experimentation.

The team then took these brain tissue samples and combined them with various chemicals with the goal of discovering which chemical compound would enable the brain tissue to survive being frozen and still enable growth following its thawing. According to the team's results, which were published in the scientific journal Cell Reports Methods, the most successful combination of chemicals was methylcellulose, ethylene glycol, DMSO, and Y27632 - together, the solution is called MEDY.

It was only recently that NASA confirmed a massive solar flare taking place on the surface of the Sun, with officials confirming its the biggest solar eruption of the last 20 years and this 11-year cycle.

The solar flare took place at 12:51 pm ET on May 14 and was captured by NASA's Solar Dynamics Observatory. For those that don't know, a solar flare happens when the Sun's magnetic field lines are contorted and snap, resulting in a massive outburst of X-rays and ultraviolet radiation. These solar eruptions can significantly impact Earth by causing interference with satellite communications, power grids and GPS signals.

Additionally, a solar flare can typically be paired with a coronal mass ejection (CME), which is a blast of solar plasma, or charged particles. When these charged particles either from the CME or the initial flare hit Earth they can produce auroras to appear at lower altitudes, or further south than they typically do. NASA JPL compiled the images of the May 14 solar flare and placed them into a video, which can be seen above.

The first human to accept a Neuralink brain chip implant was able to control a PC through their thoughts, and now the Elon Musk-led company is looking for its second participant.

In early March, Neuralink showcased a 29-year-old man named Nolan Arbaugh, who was unfortunately paralyzed from the neck down following a tragic diving accident eight years ago. Arbaugh demonstrated the capabilities of the Neuralink brain chip called "Telepathy" in a video that showed him controlling the cursor on a PC and even playing a game of Mario Kart against another player.

Neuralink has since taken to its official X account to share a video of Arbaugh talking about his motivations behind agreeing to participate in the trial, saying that he wants to help future quadriplegics based on what is learned from his involvement now. Notably, Arbaugh said the surgery for the brain implant was "super easy," and there was a significant learning process to differentiate "imagined movement versus attempted movement" in order to control a cursor on a PC.

Officials have confirmed the Sun has launched the strongest solar flare of this solar cycle, an 11-year period that takes the Sun from its least active to its most active.

The National Oceanic and Atmospheric Administration's (NOAA) Space Weather Prediction Center recently announced the eruption of a solar flare that measured X8.7, which resulted in radio blackouts and widespread auroras around our planet. Notably, researchers pinpointed the source of the massive solar flare to the sunspot region 3664, which reports indicate measure at least 15 Earths wide.

For those that don't know, a solar flare is caused by magnetic disturbances in the Sun, specifically when the magnetic field lines of the Sun are twisted and contorted. The snapping of these magnetic field lines results in the release of powerful exertion of X-rays and ultraviolet radiation. Additionally, a solar flare can also release what is called a coronal mass ejection (CME), which is a powerful wave of charged solar particles that can hit Earth if the planet is in the direction of its trajectory.

A team of researchers has created an advanced version of silicon that could be used as the foundation for the next generation of computing.

The new breakthrough technology is described as an extremely pure form of silicon, the semiconductor material used in traditional computers, and has been detailed in a new study published in the journal Nature Communications Materials. According to the paper, the new form of silicon could be used to bring quantum computing to silicon-based hardware, making these powerful next-generation computers much more accessible to everyone.

A rudimentary explanation of quantum computing is as follows. Traditional computers operate by encoding in binary, 1's or 0's. A quantum computer can encode data separately and in both 1's and 0's, or what is called a qubit, superposition of both of these states. This state is called "coherence" and enables processing calculations much faster than traditional forms of encoding. However, quantum computing has its challenges, as qubits have proven to be "noisy," which means outside elements can easily interfere with the stability of the quantum state of data.

Elon Musk has confirmed that SpaceX's Starlink satellite constellation was hit by a blast from the Sun, causing the satellites to buckle under "a lot of pressure".

SpaceX's constellation of Starlink satellites, which total nearly 6,000, managed to survive recent intense solar activity within Earth's upper atmosphere. More specifically, Elon Musk's SpaceX mentioned that a geomagnetic storm was causing "degraded service" for its Starlink satellites, which increases the density of Earth's upper atmosphere and can cause GPS communications to be scrambled.

However, all appears to be well, with SpaceX taking to its X account to announce that "All Starlink satellites on-orbit weathered the geomagnetic storm and remain healthy". Notably, this wasn't just any old geomagnetic storm, as conditions reached level 5 on the 5-point scale of geomagnetic activity on Friday, according to the Space Weather Prediction Center (SWPC), which echoes the comments Musk made on his X account, "Major geomagnetic solar storm happening right now. Biggest in a long time."

By the end of the decade an asteroid that measures approximately 1,000-foot-wide will approach Earth, and this asteroid has been named after the Egyptian god of chaos and destruction.

The closest approach of the asteroid called Apophis will occur on April 13, 2029, and due to its incredible size and close proximity to Earth, a safe but extremely close 30,000 miles, skywatchers will be able to observe the asteroid with the naked eye. Apophis has been at the top of the European Space Agency's (ESA's) "impact risk list" of potentially hazardous asteroids (PHAs) and NASA's Sentry Risk Table for 17 years, but further analysis by NASA determined it won't hit Earth for at least the next 100 years.

So, what's the big deal? NASA plans on using the close approach of Apophis as an opportunity to learn more about near-Earth asteroids, and space rocks in general, as Apophis formed around the same time the as the planets, making its material extremely valuable to researchers that want to piece together the long evolution of the solar system.

NASA has taken to its website to highlight a "rocky" planet approximately 41 light-years from Earth within the constellation Cancer.

That planet is called 55 Cancri e, and is referred to as a super-hot super-Earth exoplanet by researchers as it has a diameter twice that of Earth and has a composition similar to our planet's. As for super-hot, 55 Cancri e orbits its host star at approximately 1.4 million miles, or about one-twenty-fifth the distance between Mercury and the Sun. Due to its extremely close proximity, 55 Cancri e is believed to be tidally locked to its star, meaning only one side of the planet is facing the host star - exactly how from Earth we can only see one side of the Moon.

NASA's James Webb Space Telescope (JWST) pointed its sensitive infrared images at the planet and measured the light coming off it. By measuring the light researchers are able to determine what elements are present in the atmosphere, and the first indication 55 Cancri e could have a substantial atmosphere came from temperature measurements, or the heat energy given off in the form of infrared light.

Astrophotography can be really easier and really difficult, and sometimes the most difficult attempts at capturing the cosmos pay off immensely. This is one of those examples.

Astrophotographer Betul Turksoy captured what is called an analemma, which is a figure 8 curve that is created from the elliptical curve of the Moon. Where it gets difficult is the requirements to take the above photograph. The above photograph was featured on NASA's Astronomy Picture of the Day on October 10, 2022, where it's explained to capture an analemma, typically of the Sun, the camera needs to be planted in a single spot and the time of the time of the Sun marked for the first photograph. Then, take a photograph at the same time each day for one year.

However, a Moon analemma comes with some caveats. According to NASA, on average, the Moon returns to the same position in the sky about 50 minutes and 29 seconds later each day, which means to achieve a true Moon analemma, every photograph needs to be taken 50 minutes 29 seconds later each day. The duration of the photography bout will be one lunar month. Due to the above taking two months to capture, it technically shows a double lunar analemma.

NASA has taken to its website to reveal some brief plans for constructing the first levitating robot on the surface of the Moon.

NASA's Jet Propulsion Laboratory has proposed plans to construct the first lunar railway system, which will be designed to provide reliable, autonomous and efficient payload transport between locations on the surface of the Moon. The space agency has proposed developing FLOAT, or Flexible Levitation on a Track, which is a system that uses magnetic robots that levitate over the track.

How is this possible? NASA explains the track will be comprised of three layers: a graphene layer that enables robots to float above it using diamagnetic levitation, a flex-circuit layer to generate electromagnetic thrust to move the robots along the track, and an optional, but preferable solar panel layer to catch any sunlight. The additional benefits of FLOAT is the robots won't be touching the track, which minimizes the chance of wear and tear.
