The US military announced on Saturday that it detected an unknown object on its radar system moving through airspace close to Montana, sparking officials to close a region of airspace above the state.

Recently released reports state that US military detected the object, and the North American Aerospace Defense Command (NORAD) sent a fighter aircraft to inspect the area. In response to this radar anomaly, the Federal Aviation Administration (FAA) closed the airspace for the Department of Defense to conduct activities. The closed airspace stretched 50 nautical miles around Harve, Montana, located near the Canadian border.

The FAA issued similar flight restrictions when the US military brought down a Chinese spy balloon that was detected off the coast of South Carolina. Recent reports state that the fighter jet inspected the area where the object was detected and found nothing. NORAD issued a statement and said its aircraft "did not identify any object to correlate to the radar hits. NORAD will continue to monitor the situation." Since no object was found, the FAA has reopened the airspace.

Canadian Prime Minister Justin Trudeau took to Twitter to announce that he ordered the takedown of an unidentified object that was violating Canadian air space on Saturday, February 11.

The object that was invading Canadian air space was similar to the object that was taken down by another F22 aircraft on Friday, in the regard that officials weren't able to determine exactly what it was. According to reports, President Biden and Trudeau spoke on Saturday afternoon about the object and emphasized the importance of recovering what was left of the about to determine more details about its purpose and origin. So, what was the object?

Officially, there is no specific description of the object - at the moment. According to Canada's defense secretary, Anita Anand, the object appeared to have a cylindrical shape and was smaller than the Chinese spy balloon that was brought down by US military a week ago. Notably, the unknown object was detected on Saturday evening by Pentagon officials, which promptly dispatched American fighter jets that were later accompanied by Canadian fighter jets to monitor and track the object.

The White House has announced that the U.S. military has taken down an unidentified flying object off the coast of Alaska.

The news of the Alaskan object being taken down comes after the U.S. government announced it successfully brought down a Chinese weather balloon off the coast of South Carolina. The balloon was suspected of conducting intelligence operations, and President Biden ordered its removal from U.S. airspace. The wreckage from the balloon was recovered a few days ago, and officials said that the balloon was equipped with multiple devices capable of intercepting and geolocating communications.

On Friday, the Pentagon commented on the object detected off the coast of the northeastern part of Alaska, saying it was much smaller than the Chinese weather balloon brought down a week earlier and that F22 shot down the object at 1:45 pm E.S.T. Notably, the Pentagon said the object was flying at about 40,000 feet and posed a risk to civilian air traffic, hence the decision for it to be taken down. U.S. Brig. Gen. Patrick Ryder, the Pentagon's chief spokesperson, said that pilots that flew alongside the object determined that the object was unmanned, was unable to maneuver in the air, and didn't resemble an aircraft.

NASA's Curiosity rover has been exploring the surface of Mars since 2012 and has just found evidence of Mars having a watery past.

NASA has taken to its blog on its website and its social channels to share a discovery by its Curiosity rover. According to the space agency, Curiosity team members believed that they'd seen the last evidence of ancient lakes covering the region the rover is currently exploring. The reason for the team's doubt was simply due to rock layers where Curiosity is station forming under much drier conditions than regions the rover has previously explored.

To researchers' surprise, Curiosity has now found the clearest evidence of Mars' watery past than it ever has in the past. Curiosity has been traversing the foothills of Mount Sharp since 2014, as NASA believes the 3-mile-tall mountain would have once had many streams and lakes, making it a rich environment for any ancient microbial life. NASA explains that Mount Sharp consists of layers ranging from the oldest at the base of the mountain and the youngest at the top.

A newly released satellite image has revealed the devastated region in Turkey that was only recently hit with a powerful 7.8 magnitude earthquake.

According to reports on February 6, a series of violent earthquakes struck southern and central Turkey, along with western Syria. The first was the 7.8 magnitude earthquake that hit Turkey and Syria, causing hundreds of buildings to collapse and the death of what is estimated to be 11,200 people. Teams are still on the ground, attempting to find any survivors underneath the piles of rubble. The second earthquake came only hours after the first and measured 7.5 in magnitude, shaking both Turkey and Syria.

The above image was published on Twitter by Planet, where the company says one of its satellites captured a birds-eye-view of the disaster-stricken city Kahramanmaras, a city in the Mediterranean Region of Turkey. At the moment, there are few satellites images of the disaster, but companies such as Planet, Maxar, NASA, the National Oceanic and Atmospheric Administration (NOAA), and the European Space Agency are working on capturing valuable satellite images of the region that will then be given to officials assisting the people of affected regions.

SpaceX has recently conducted a pivotal test on its journey to creating the transportation necessary to get humans to the surface of Mars.

SpaceX took to its social media channels to share footage of Booster 7's static fire test that was held at the company's Starbase facility in South Texas. The objective of the first stage static fire test was to gather data on the 33 Raptor engines that were intended to be fired. Unfortunately, only 31 of the Raptor 2 engines ignited, but overall the test seemed like a success as 31 Raptor 2 engines provided more than enough power to get Starship to orbit.

For those that don't know, SpaceX's Starship launch vehicle has been in development for many years now, but now development is reaching a critical point as the rocket is almost ready for its first orbital flight test. This static fire test of 31 Raptor 2 engines has tested the Ground Support Equipment (GSE), which has never felt the pressure of 31 Raptor engines firing at the same time. Additionally, SpaceX engineers will gather valuable information on Booster 7's health after the firing, which will be used to make not only Booster 7 more efficient but also future vehicles that will come after it.

The United States government has claimed that China is lying about its intentions with its mysterious weather balloon that was recently shot down.

Last week the US government successfully shot down a Chinese weather balloon that was suspected of being capable of gathering data on neighboring American military facilities. American military brought the balloon down on Saturday as it was flying approximately 60,000 feet above sea level six nautical miles off the shore in Myrtle Beach, South Carolina. China responded to the attack on its balloon, claiming that it was caused by a "civilian" accident, and condemned the decision to attack a "civilian unmanned airship by force."

Additionally, China claimed that Beijing "repeatedly" informed the US military that the balloon was entering its airspace and that it was for civilian use only. Furthermore, China vowed that it would respond to the attack, as it believes the threat of the balloon was an "obvious overreaction and a serious violation of international practice".

A group of scientists has discovered rings around an object that resides in the frozen debris region beyond Neptune and Pluto.

Researchers have published their findings in the scientific journal Nature and explain that using the world's largest optical telescope, the 34-foot-wide Gran Telescopio CANARIAS in the Canary Islands, Spain, to hone in on a dwarf planet called Quaoar. This dwarf planet doesn't meet the specifications to make it a full planet, but it does feature something special - rings, much like Saturn.

The report states that astronomers before this discovery didn't believe that rings could exist at such great distances from their host celestial bodies, especially small celestial bodies such as Quaoar. The small dwarf planet is approximately four billion miles away from Earth and is only 690 miles in diameter, making it half the size of Pluto, another dwarf planet.

A group of astronomers has used the SMARTS 1.5-meter Telescope at Cerro Tololo Inter-American Observatory in Chile to discover what is being described as the first example of a rare type of star system.

According to a press release and a study published in the scientific journal Nature, the team of astronomers discovered this unusual star system called CPD-29 2176, which is located approximately 11,400 light-years away from Earth. The star system is so rare that the researchers estimate there are only about ten such star systems within the entire Milky Way galaxy. So, what makes it so rare? CPD-29 2176 was found to have the right conditions for a kilonova to take place, an extremely powerful explosion that occurs when a neutron star collides with another neutron star.

The astronomers outline in the press release that data from the SMARTS telescope informed researchers on the orbital characteristics of the star system and what stars it consists of. The researchers found one neutron star that was created by an ultra-stripped supernova, an end-of-life explosion of a massive star that has had much of its outer atmosphere stripped away by a companion star. Additionally, the researchers found a second closely orbiting star that is on its way to becoming an ultra-stripped supernova.

A team of researchers used an artificial intelligence system to identify some "suspicious" radio signals that may have an extraterrestrial origin.

University of Toronto student Peter Ma spoke to New Atlas, where he explained that he developed a new machine-learning algorithm that is designed to sort through radio signals that are detected from deep space. Ma brought the AI to Breakthrough Listen, an Australian-based initiative that aims to detect artificial radio signals coming from other planets or locations in our solar system in hopes of being able to discover life outside of Earth.

For example, if a high-tech alien race scanned Earth, they would pick up the many radio signals that are bouncing around our planet. Breakthrough Listen plans on doing that, but for any signal coming to Earth. However, the task is not a small one, as there are many radio signals out in deep space, and the majority of them come from stars, black holes, quasars, supernovae, and many other objects that can release radio signals. Since the universe is quite noisy, humans struggle to filter through and categorize all of the detected radio signals, which is where artificial intelligence comes into play.

NASA's James Webb Space Telescope has captured an image of an asteroid that's approximately the size of Rome's Colosseum.

An international team of European astronomers has used Webb's Mid-Infrared Instrument (MIRI) to detect an interloping asteroid that's estimated to be anywhere between 300 and 650 feet wide, or approximately the size of Rome's Colosseum. While that may sound like a large asteroid, NASA writes that this object is likely the smallest object Webb has observed so far and could be a great example of an object that measures under 0.6 miles that resides within the main asteroid belt located between Mars and Jupiter.

Webb's observations of the asteroid were published in the scientific journal Astronomy and Astrophysics, where it's explained that the asteroid was detected while Webb was performing calibration testing for its MIRI instrument. Researchers pointed the MIRI instrument at the main belt asteroid 1998 BC1 and began taking calibration images. According to NASA, these tests failed for technical reasons such as brightness and the telescope not being pointed at the right target.

NASA's car-sized Mars rover named Curiosity has stumbled across an iron-nickel meteorite while exploring a region of Mars.

NASA has taken to its social channel and explained in a blog post on the NASA Jet Propulsion Laboratory website that the Curiosity rover found the iron-nickel meteorite on January 28, 2023, in a region around Mount Sharp, a large mountain located in the Gale crater. NASA has written on the Curiosity rover Twitter account that it's not "uncommon to find meteorites on Mars" and that this isn't the first discovery by Curiosity. In 2016 the rover discovered a meteorite now called "Egg Rock", or the golf ball.

As for the meteorite that Curiosity most recently found, NASA writes that its approximately 1 foot wide and has been named Cacao. The space agency explains that Curiosity snapped a panorama with its Mast Camera, or Mastcam, which features a 100-millimeter focal length lens. The panorama consists of 19 individual images that are then stitched together to form the above image. This image is then color corrected to "match lighting conditions as the human eye would perceive them on Earth," writes NASA.

A team of archaeologists in Japan has discovered a massive iron sword that was buried to protect the dead from evil spirits.

In an email to LiveScience, Riku Murase, an archaeologist for Nara City who dug up the burial mound and found the sword, said they were "surprised" at the discovery, and they doubted the existence of the tomb for "so long". The discovery took place last November at the burial mound of Tomio Maruyama, located west of Nara, a city in Japan. The tomb dates back to the fourth century A.D. (1,600 years ago) and contained a Dako, a type of sword known for its wavy, snake-like shape.

Commenting on the discovery of the sword, Murase said that it's twice as big as any other sword that has been found in Japan so far. The below image showcases an X-ray photograph of the sword's original shape and size. Archaeologist Stefan Maeder, an expert in Japanese swords and ancient swords in general, explains that dako swords found in burial mounds are mainly for ceremonial purposes, but aren't "common" as they are "prestigious objects of high society".

Scientists are sharing a new level of both excitement and confusion at the vortex that just formed near the north pole of the sun.

Space weather forecaster Tamitha Skov took to Twitter to share video footage captured by NASA's Solar Dynamics Observatory, which showcases a large filament of solar plasma snapping off of the sun's surface and forming a vortex that moved towards the sun's north pole. According to Skov, there are large implications for this event as it could unlock a deeper understanding of the sun's atmospheric dynamics close to its poles, a region that currently isn't very well understood.

Other scientists, such as Scott McIntosh, a solar physicist and deputy director at the National Centre for Atmospheric Research in Boulder, Colorado, spoke to space.com and said that he has never seen a vortex quite like this and that research suggests that this event occurs once every 11 years. Notably, the vortex happened at the sun's exact 55-degree latitudes, and while scientists know that it happens once every 11 years, they don't know why it happens or the driving force behind it.

A team of researchers has successfully cloned three "super cows" that are capable of producing nearly double the amount of milk than a typical dairy cow.

According to an article written in the Chinese state-run publication Global Times, a group of scientists from the Northwest University of Agricultural and Forestry Science and Technology has cloned three "super cows". The researchers report that three new calves have been born through surrogacy, the first was on December 30 and weighed 120 pounds, requiring cesarean section due to its immense size. So, why are they "super cows"?

What makes these cows "super" is that they originate from the Holstein Friesian breed that can be traced back to the Netherlands. These cows can produce as much as 18 tons of milk per year, or 100 tons of milk, throughout their lifetime. In comparison, only five in 10,000 cows have a chance at producing 100 tons of milk in their lifetime, and in most cases, it's discovered later in the cow's life that they have achieved this level of production, making breeding these "super cows" particularly difficult.

The team of astronomers from around the world have honed their efforts on one exoplanet in particular, Wolf 1069 b.

In a new paper published in Astronomy and Astrophysics by a team of fifty international astronomers details Wolf 1069, an exoplanet that is only 31 light-years from Earth and is a very similar size to our planet. The astronomers found that Wolf 1069 is about 1.26 the mass of Earth and 1.08 the size. Additionally, researchers found the exoplanet orbits its host red dwarf star much faster than Earth orbits the Sun, with Wolf 1069 only taking 15.6 days to complete one full rotation.

Since the exoplanet is orbiting a red dwarf star, it receives approximately 65% of the solar radiance that Earth receives. Red dwarf stars are much smaller and cooler than the sun, and because of that Wolf 1069's surface temperatures are also much cooler despite its close proximity. According to the paper, the exoplanet's surface temperatures range between -139.27 degrees Fahrenheit (-95.15 Celsius) and 55.13 degrees Fahrenheit (12.85 C), with an average surface temperature of -40.25 F (-40.14 C).

Researchers have performed an analysis on Saturn's smallest moon Mimas and found evidence that the small moon may actually have an internal ocean.

Mimas is Saturn's smallest and inner-most moon, and according to researchers that published a recent paper in the Geophysical Research Letters journal, NASA's Cassini Mission to Saturn identified an oscillation in Mimas' rotation, which is typically an indicator for that body being geologically active body and able to support an internal ocean. Notably, researchers first believed that Mimas wouldn't be a likely candidate for an internal ocean as its icy surface is peppered with craters and featured one giant crater that makes the moon resemble the iconic Death Star from Star Wars.

This large crater on Mimas was the focal point of the study and is called the Herschel impact basin. Scientists modeled the formation of the Hershel impact basin using simulation software called iSALE-2D. The results indicated that Mimas' crust had to be 34 miles thick when the Hershel impact occurred. Notably, recent observations of Mimas indicate that the crust is approximately 19 miles thick, leading researchers to believe that Mimas has been warming and expanding since the Hershel impact.

A team of astronomers have discovered Jupiter has more moons than what was officially recorded, adding twelve more to the total for the biggest planet in our solar system.

The twelve new moons were discovered using telescopes in Hawaii and Chile throughout 2021 and 2022. Initial data gathered by telescopes was then followed up with additional observations to confirm each orbit of the target moons. According to the results, these moons aren't very big at all, measuring ranging in size from 0.6 miles to 2 miles in diameter. Notably, the new moons have been added to the official list maintained by the International Astronomical Union's Minor Planet Center.

Previous official numbers put Jupiter's total number of moons at 80, giving it a second-place trophy behind Saturn for the planet in our solar system that features the most moons. Saturn currently has 83 confirmed moons, but now Jupiter has added another 12 to its orbit, meaning it has become our solar system's most moon-infested planet with a total of 92 confirmed moons.

A group of scientists have devised a novel way to produce skin in almost any 3D shape, which could then be transplanted as "biological clothing".

The team of researchers from Columbia University published a new study in the journal Science Advances that through their method, they are able to create three-dimensional skin constructs from ears to elbows to entire hands that can then be transplanted as 'biological clothing' to individuals that have suffered from burns those affected regions. This method involves a 3D laser scanning the site on the body that needs a skin graft.

A digital profile is then created of the scanned area, which is then tinkered with in a CAD program. After the touch-ups are complete, the 3D render is then printed. The above skin glove is entirely covered in skin fibroblasts and collagen, along with keratinocytes, which is the most common type of skin cell that makes up the structural component of the epidermis, the outermost layer of the skin on the human body. This layer of skin is responsible for repelling your body from harm, keeping your skin hydrated, and producing new skin cells.

A group of scientists looked for assistance from an artificial intelligence to make what they deemed as an accurate prediction for an approaching problem.

A new study published in the journal Proceeding of the National Academy of Science details the combined use of artificial intelligence and current climate models. The researchers behind the study explain that the United Nations Paris Agreement aims to hold global warming below far below 2 degrees Celsius and is really aiming for below 1.5 degrees or more. Since mainstream climate models state that global warming is accelerating, there has been interest in how long it will be until that 1.5 degrees Celsius threshold is hit.

According to the researchers, an artificial intelligence was fed climate models that contain data on historical temperature patterns, and according to the results, global warming is already well on its way to blowing past the 1.5 degrees threshold. Notably, the study states that even if there was a sudden substantial reduction in the amount of greenhouse gasses produced across the planet, there is still a real possibility that global warming will hit 2 degrees Celsius.
