Researchers have discovered that Saturn's moon Enceladus was far more tectonically active than previously thought after analyzing recent measurements of material from the moon's surface.

A new study published in the scientific journal Icarus details measurements conducted on the material that coats the surface of Saturn's moon Enceladus. According to the study, the material is called 'regolith' and has an appearance very similar to snow found on Earth. However, Enceladus' snow isn't formed the same way normal snow is formed on Earth.

The researchers explain that the regolith is created through snow cannon-like plumes, or ice geysers erupting and shooting large quantities of particles up into the atmosphere that then fall back down to the moon's surface. Smaller particles launched by the eruption are shot into space and eventually become part of Saturn's iconic rings. While scientists are quite sure that Enceladus' snow is coming from surface eruptions, the researchers are in the dark when it comes to the physical properties of the regolith material.

A college student has used Open AI's chatbot called ChatGPT to write an essay about burqa bans that they then submitted for grading.

According to a report from The New York Times, the student confessed to using the chatbot to write the essay after their teacher, philosophy professor Antony Aumann from Northern Michigan University, busted them. Aumann explained to Futurism that the student was instructed to rewrite the essay, which is what is done the majority of the time in plagiarism cases.

Chatbots such as OpenAI's ChatGPT are free and have very powerful capabilities that are resulted in them going viral. ChatGPT is an artificial intelligence designed to have human-like conversations where it remembers what was talked about earlier in the conversation. Additionally, users make improvements to the AI's answers, write code, essays, format data, create programs, and more. An example of a prompt would be, 'write an essay on burqa bans'. A more simpler request could be, 'Got any creative ideas for a 10 year old's birthday?'

A rogue asteroid has been spotted photo-bombing NASA's Hubble Space Telescope's field of view as it attempts to observe a nearby galaxy.

The European Space Agency (ESA) has taken to its website to explain the "visitor to a galaxy", as displayed in the above image. The above image was captured by NASA/ESA's Hubble Space Telescope that was pointed at the small galaxy known as UGC 7983, which appears as a hazy cloud of light in the center of the image.

This small galaxy is located approximately 30 million light-years from Earth within the constellation Virgo and is categorized as a dwarf irregular galaxy that is believed to be one of the earliest galaxies to form in the universe.

A team of astronomers has used the Green Bank Telescope to capture what is now being described as the most detailed image of the Moon ever taken from Earth.

A new report from BGR has claimed that the new images of the surface of the Moon by the Green Bank Telescope are the most detailed photographs humans have captured from the surface of Earth. The Green Bank Observatory took to its website to explain that it used the National Science Foundation's Green Bank Telescope (GBT) and Very Long Baseline Array (VLBA) to capture the highest-resolution radar images of the Moon, which will be used to pave the way for next-generation radar systems that'll study planets, asteroids and other moons within our solar system.

The press release states that a low-power radar transmitter, capable of 700 watts of output power at 13.9 GHz, was tested on the GBT. Astronomers aimed the telescope at the Moon's Tycho crater "An image of the Tycho crater was captured with a 5-meter resolution, showing unprecedented detail of the Moon's surface from Earth. "It's pretty amazing what we've been able to capture so far, using less power than a common household appliance," emphasizes Patrick Taylor, radar division head for GBO and NRAO."

Elon Musk's private jet was very active throughout 2022, with the Tesla and SpaceX CEO taking more than 100 flights in total.

Musk has publicly stated many times that he is attempting to save the planet through the reduction of greenhouse gas emissions. Tesla and the electric vehicles it produces are a reflection of these statements, and it quickly became a pioneer of the electric vehicle industry. However, some question Musk's effort for a cleaner world and point to the emissions that are produced by his private jet.

According to a report that cites a bot that tracks Elon Musk's private jet whenever it takes off and lands at an airport, Musk has taken a total of 134 flights throughout 2022, with the billionaire doing international travel to eight different countries. The Twitter account also estimated the total amount of CO2 produced by Musk over his travels, and according to reports, Musk's Gulfstream G650ER private jet burns 503 gallons of fuel for every hour of flight, meaning it burnt 178,686 gallons or 709,578 liters of fuel during the year and produced 1,895 tons of CO2 emissions.

The world's most populated nation has recorded its first population decline in declares, according to a new report released by the National Bureau of Statistics.

The new report was released on Tuesday and stated that China had 850,000 fewer people at the end of 2022 than it did at the end of 2021. Notably, the report states that the census of people included populations in mainland China and excluded places such as Hong Kong and Macao. The report goes on to state the nation's total was 1.41 billion people, with 9.56 million births against the 10.41 million deaths recorded.

Furthermore, the report found that Chinese men greatly outnumber Chinese women, with the report finding there are 722.06 men and 686.69 million women. This disparity between total men and women can be, at least in part, attributed to the strict one-child policy that was implemented in the late 1970s / early 1980s. The one-child policy was abandoned in 2016 and was followed by Chinese authorities encouraging residents to have multiple children.

A group of researchers has tested the effects of robotic AI-powered fluffy seals on astronauts as part of an overarching effort to eventually send the sophisticated toys into space.

A new article in the South China Morning Post details a group of researchers that created fluffy robotic baby seals called Paros. These machines are designed to alleviate the stress and loneliness experienced by astronauts living on Mars throughout the early stages of the colonization process. The robotic seals have already been tested in a simulation where a crew of six spent two weeks in a simulated Mars environment operated by the Mars Society in Utah.

The simulation required the crew to perform first-aid drills, grow their own food, and take rock and soil from Mars. Additionally, the crew tested a Paro that was given to half of the crew for the first week and the other half of the crew the following week. Notably, the robotic seal is equipped with a dual 32-bit processor, three microphones, 12 tactile sensors, touch-sensitive capabilities via its whiskers, and several motors and actuators that give it its limited movement. The stress-relieving robot measures in at 22 inches from head to tail and weigh 5.7 pounds.

Elon Musk has shared a video to his Twitter account showing what he believes will be how humans land on the Red Planet in the future.

The Twitter, Tesla, and SpaceX CEO shared a video posted on the SpaceX Twitter account, which showcased the Falcon Heavy rocket safely landing back on the launch pad after completing its mission from the U.S. Space Force. Elon Musk's company launched the Falcon Heavy from Launch Complex 39A at Kennedy Space Center, Florida, on January 15 at 5:56 p.m.

The mission titled USSF-67 was to geostationary orbit and carried a payload that featured the U.S. Space Force's Continuous Broadcast Augmenting SATCOM (CBAS)-2 communications satellite, a satellite designed to relay data from existing satellites and the Long Duration Propulsive ESPA (LDPE)-3A, a 6-slot payload adapter made by Northrop Grumman that had five slots taken up by military satellites.

A team of researchers has examined a meteorite that crashed into a family's driveway only a few years ago and found that it contains organic matter.

A new study published in the journal Science Advances details the discovery of organic matter that contains a selection of the building blocks of life or the molecules/compounds required for carbon-based life to exist. Scientists examined the composition of the meteorite and found traces of soluble protein amino acids that they believe formed much earlier in the meteorite's life. Researchers explain that the organic matter likely formed when the meteorite was attached to its much larger parent asteroid that harbored liquid water.

It should be noted that this isn't the very first-time researchers have discovered organic matter inside of a space rock that has fallen to Earth, but considering the results from the examination and the way the meteorite was discovered (in a driveway), this particular meteorite has entered into the "rare" category, according to study lead author Queenie Chan, a planetary scientist at the University of London. Chan explains that the Winchcombe meteorite "belongs to a rare type of carbonaceous meteorite which typically contains a rich inventory of organic compounds and water".

NASA has taken to its blog to announce that its James Webb Space Telescope has confirmed its first exoplanet, which was found to be very similar to Earth in terms of size.

The exoplanet was originally classified as LHS 475 b was identified by Webb, and according to NASA's blog post, the planet clocks in at 99% of Earth's diameter, making it almost the exact same size as our pale blue dot. Researchers from the Johns Hopkins University Applied Physics Laboratory led the discovery and explained that Webb's Near-Infrared Spectrograph (NIRSpec) captured the planet easily and clearly. Webb's observations found that the planet is small, rocky, and doesn't feature an atmosphere that is methane heavy.

NASA writes that researchers are currently exploring the acquired data to determine what type of atmosphere the exoplanet has, or if any atmosphere at all. At the moment, the team can't conclude what is present in the atmosphere but can deduce what isn't present in the atmosphere, hence the aforementioned lack of methane.

The United States government is beginning to take UFO sightings by US military personnel much more seriously, per a newly released report from the Pentagon.

The report that has since been released was originally delayed by a month and has now been published by the Pentagon's Office of the Director of National Intelligence (ODNI). Multiple intelligence agencies, such as the Federal Aviation Administration, NASA, the National Oceanographic and Atmospheric Administration, and the Department of Energy, provided valuable information for the report.

In total, the Pentagon's report included 510 instances of catalog UFO reports from multiple sources within the US military, with the majority of the sightings being provided by the US Air Force and Navy. Of these 510 cataloged UFO reports, 26 were found to be uncrewed aircraft systems (UAS), or drones, 163 were likely balloons or "balloon-like entities", and six were determined to be airborne "clutter," which covers things such as birds, airborne plastic and more.

The tumultuous takeover of Twitter by SpaceX and Tesla CEO Elon Musk will continue as the new Twitter owner continues his strategy of moving fast with development and breaking some stuff along the way.

A new report from The Information has revealed that top advertisers have been warned that Musk's unpredictability at the company will continue and that they need to get used to it. The report also stated that Twitter executives are becoming more and more desperate for fresh revenue from advertisers, as GroupM, the world's largest ad-buying company, has reduced spending on Twitter by anywhere between 40% to 50%.

Notably, Twitter is experiencing an overall downturn in advertising spending as Elon Musk moves to open up the platform towards more free speech, broadening the variety of content on the platform. Unfortunately, some leading advertisers don't want their brands associated with the content that is now allowed on the platform, resulting in them pulling advertising spending, the aforementioned hemorrhaging of Twitter's advertising revenue.

Russia is planning on getting an empty Soyuz capsule to the International Space Station to replace a malfunctioned spacecraft that was originally intended for cosmonauts returning back to Earth.

Russia's space agency concluded that Soyuz MS-22 suffered a coolant leak on December 24, around the same time Russian cosmonauts Sergey Prokopyev and Dmitri Petelin were preparing for a spacewalk. Coolant spewed from the leak for hours, which caused officials to call off the spacewalk and assess the situation. It was found that the coolant leak now prevents the Soyuz MS-22's radiator from working effectively, meaning that the spacecraft was unable to cool the cabin, resulting in possible temperatures of more than 104 Fahrenheit.

With the possibility of extreme temperatures inside the spacecraft, Roscosmos decided that Soyuz MS-22 will return to Earth, but without a crew, and the replacement Soyuz MS-23 will be sent up for the ISS-stationed cosmonauts. According to a report from SpaceNews, Russia's new plan to replace the malfunctioned spacecraft includes sending the Soyuz MS-23 up to the International Space Station with cargo on February 20.

NASA is already talking about a successor to its extremely impressive James Webb Space Telescope that began its operations last year and has already provided valuable information to researchers.

The space agency hasn't confirmed anything specific, but at a meeting of the American Astronomical Society, a group of astronomers listened to NASA talk about a Webb successor that would be approximately the same size as Webb (about 21 feet). This successor would also be stationed at Lagrange point 2, where Webb is situated, and be repairable via robots- enabling the next-gen space telescope to operate for multiple decades.

Mark Clampin, NASA's astrophysics division director, spoke to the audience and said while nothing is set in stone, he does have a name for the telescope: the Habitable Worlds Observatory (HWO). Notably, the next great observatory to launch won't be the HWO, as NASA already has plans on launching the Nancy Grace Roman Observatory in 2027, which will be an observatory dedicated to gathering data on dark energy and exoplanets.

NASA's Artemis 1 mission was declared a success when the Orion spacecraft was safely retrieved from its splashdown location on December 11 and then transported back to NASA facilities in Florida on December 30 for processing.

Now the space agency has taken to its blog on its website to announce that NASA technicians have finally opened up the Orion capsule to begin an assessment of how the spacecraft held up throughout its 1.4 million-mile journey beyond the Moon and back to Earth. NASA writes on its website that the above photo shows a technician standing inside the crew module, assessing the health of the interior and removing any payloads.

The space agency writes that teams have already removed any purposeful passengers (mannequins equipped with various sensors that'll inform NASA on how space influences human health) and Snoopy, NASA's zero-gravity indicator.

An Australian woman has kicked a robot dog that was being tested while walking down a street, and it seems the woman kicked the dog for no reason at all.

The video was shared by the dogs operator Mark Trueno, who was interviewed by Vice where he explained that he was walking the robot dog named Stampy down a street in Brisbane, Australia, at about 2:30 am when a woman walking along a sidewalk approached the dog and kicked it, resulting in about $2,500 worth of damage to Stampy's forward-facing sensor array.

A biotech startup out of San Diego has put forward a claim that will undoubtedly get some eyes within the scientific community as the researchers say they've reprogrammed mice genes and doubled the lifespan of the subject.

The claim comes from San Diego biotech startup Rejuvenate Bio, which published a study on bioRxiv, a preprint server, yet to be peer-reviewed, and states that a team was able to successfully reprogram mice cells by exposing them to various proteins that are found within early-stage mice embryos. Through this exposure, the researchers were able to change the genes of the mice, which led them to find that the mice treated with this gene therapy lived 18 weeks longer on average than mice that didn't receive the treatment.

While the claims are certainly eye-opening, researchers will need to go through the study to authenticate the data as well as the results before any awards are handed over to Rejuvenate Bio. Additionally, many members of the scientific community have previously voiced concern over this experiment as the gene-altering technique was found to have caused mice to develop cancer after receiving the treatment.

Virgin Orbit's "Start Me Up" mission failed to reach orbit on Monday, January 9th, 2023, as the company informed the public over a webcast, resulting in the loss of nine satellites.

The mission, which was the company's sixth orbital flight, was launched from Spaceport Cornwall in the United Kingdom, using the company's carrier plane called Cosmic Girl. The LauncherOne rocket was dropped from the carrier plane at 6:09 p.m. EST (2309 GMT), while the plane was off Ireland's southwest coast, but suffered an anomaly which prevented it from reaching orbit.

The lost payloads included an in-orbit manufacturing experiment from the U.K. company Space Forge, several U.K. defense cubesats, and an experimental global navigation satellite co-funded by the European Space Agency. This was an important mission for Virgin Orbit as it marked the first time the company used Spaceport Cornwall and opened a new launch chapter for the company.

NASA's instruments have detected a strong solar flare erupting from an extremely active sunspot region, according to a recent NASA blog post.

The space agency took to its website to announce that its Solar Dynamics Observatory detected the strong solar flare being emitted on January 9 at 1:50 pm EST, and that the event was photographed as displayed by the above image. The flare was classified as an X1.9 flare, with 'X' representing the most intense categorization of a solar flare, followed by M, C, B, and A. The difference between each of the letters is a 10-fold increase in energy output. So an X is ten times an M and 100 times a C.

Solar flares are intense eruptions of energy that are released by the Sun after there is a massive build-up of magnetic energy that has accumulated in the solar atmosphere. Solar flares are also typically associated with sunspot regions, which are regions producing strong magnetic activity. These flares, along with other forms of solar activity, such as coronal mass ejections (CME), have the potential to disrupt various types of communication systems on Earth, depending on the severity of the event.

NASA has said a final goodbye to a vintage satellite that was launched back in 1984 in an effort to study how the Sun's energy was both absorbed and radiated by the Earth.

The 5,400-pound Earth Radiation Budget Satellite (ERBS) was launched on the back of the space shuttle Challenger and provided researchers with lots of valuable information regarding the balance between the energy that the Earth receives from the Sun and the energy that the Earth radiates back into space, which allowed for a deeper understanding of Earth's climate and weather patterns.

Notably, ERBS was outfitted with many instruments that allowed it to measure the amount of incoming and outgoing radiation in different parts of the electromagnetic spectrum, which included visible light, ultraviolet, and infrared. Additionally, the satellite was also equipped with an instrument that allowed it to measure the temperature and moisture profiles in different regions of Earth's atmosphere, which, like all of the other data it acquired while it was operating, fed into researchers' climate models, improving their accuracy.
