What happens if you fall into a black hole? NASA simulations provide an answer.
NASA has released new simulations showing what would happen if a person fell into a black hole. The simulations use a virtual supermassive black hole with a mass 4.3 million times that of our sun, similar to the black hole Sagittarius A* at the center of the Milky Way. One simulation shows approaching the black […]
‘Lost’ satellite found after orbiting undetected for 25 years
A satellite called Infra-Red Calibration Balloon (S73-7) that was launched in 1974 to be a calibration target for remote sensing equipment has been rediscovered after orbiting undetected for 25 years. The satellite got separated from its parent spacecraft after launch but failed to inflate as intended. It then orbited in space anonymously for decades. Astrophysicist […]
On D-Day, 19-year-old medic Charles Shay was ready to give his life, and save as many as he could
– Charles Shay, a Native American WWII veteran who served as an army medic on D-Day at the age of 19. – On June 6, 1944, Shay landed with American troops on Omaha Beach in Normandy. He treated many wounded and dying soldiers amid intense fighting and chaos on the beach. – Despite the danger […]
Antarctic ice hole the size of Switzerland keeps cracking open. Now scientists finally know why.
– Scientists have discovered what causes a large ice hole the size of Switzerland to periodically form in Antarctica’s Weddell Sea, solving a decades-long mystery. – Known as the Maud Rise polynya, the hole was first observed in the 1970s but would appear sporadically, leaving its cause unclear. It reopened at a massive size in […]
Citizen scientists find remarkable exoplanet, name it after Harry Potter character
– Citizen scientists helping NASA’s TESS exoplanet hunting mission have discovered a new exoplanet orbiting a binary star system around 309 light years from Earth. – The exoplanet, known as TOI 4633 c but nicknamed “Percival” after a Harry Potter character, is around three times the size of Earth and orbits in the habitable zone […]
Scientists Say Underwater Cave So Deep They Can’t Find the Bottom
– Scientists have discovered the deepest known underwater sinkhole (known as a blue hole) located off the coast of Mexico and Belize. – The sinkhole is called Taam Ja’ Blue Hole (TJBH) and was previously thought to be the second deepest blue hole. – A new study published findings that TJBH extends to at least […]
Astronauts to launch from Cape Canaveral for first human spaceflight in nearly 56 years
– For the first time in over 56 years, astronauts will be launching from Cape Canaveral Space Force Station in Florida next week aboard Boeing’s Starliner spacecraft on an Atlas V rocket. – The last time humans launched from Cape Canaveral was in 1968 for the Apollo 7 mission. – The two NASA astronauts assigned […]
Tiny, transparent chip could transform your smartphone into a professional-grade camera
– Scientists have developed a new type of tiny, transparent chip that could improve the photo quality of smartphone cameras significantly. – The chip is made from a 2D semiconductor material that is just a few atoms thick, making it transparent. It contains an array of over 10,000 pixel units that can adjust transparency levels […]
‘We were amazed’: Scientists find hidden structure in nebula captured by James Webb telescope
– Scientists using the James Webb Space Telescope and the Submillimeter Array telescope have discovered a previously hidden double ring structure within the planetary nebula known as the Southern Ring Nebula. – James Webb Space Telescope images revealed the molecular hydrogen that makes up the nebula’s “exoskeleton.” Additional observations with the SMA detected carbon monoxide […]
Breakthrough 6G antenna could lead to high-speed communications and holograms
– Researchers have developed a new programmable antenna that is the world’s first capable of operating in the 60GHz millimeter-wave band reserved for 6G communications. – The prototype antenna uses metamaterials and is controlled by a field programmable gate array, allowing it to dynamically shape and control wireless signals. – In tests, it reduced energy […]
