In trying to understand the nature of the cosmos, some theorists propose that the universe expands and contracts in endless cycles called “bouncing universes.” Because this behavior is hypothesized to be perpetual, the universe should have no beginning and no end — only eternal cycles of growing and shrinking that extend forever into the future, ...
A world-first study has revealed how space travel can cause lower red blood cell counts, known as space anemia. Analysis of 14 astronauts showed their bodies destroyed 54 percent more red blood cells in space than they normally would on Earth, according to a study published in Nature Medicine. Lead author Dr. Guy Trudel, a rehabilitation physician ...
When we think of space, we think of big and empty, but when it comes to Earth’s orbit, it’s cluttered with millions of pieces of garbage that we call space junk. The junk — or space debris — is made up of uncontrollable human-made items that remain in orbit long after they’ve served their original ...
Mars, the red neighbor of Earth, has been a planet of interest, including the possibility of life on Mars, ever since scientists started exploring the universe and started considering the possibility of the existence of extraterrestrial life. The thought of being the only planet with life is often daunting. As more knowledge about the vastness ...
Jupiter is famous for its distinctive red and white bands — swirling clouds of moving gas that astronomers traditionally use to track winds in Jupiter’s lower atmosphere. Astronomers have also seen, near its poles, the vivid glowing known as aurorae, which appear to be associated with strong winds in the planet’s upper atmosphere. But until ...
An Australian research consortium has successfully tested a next-generation propulsion system that could enable high-speed flight and space launch services. The team’s rotating detonation engine, or RDE, is a major technical achievement and an Australian first. It was designed by RMIT University engineers and is being developed by a consortium led by DefendTex, with researchers ...
An international team of astronomers has published a map of the sky showing over 25,000 supermassive black holes. The map, to be published in the journal Astronomy & Astrophysics, is the most detailed celestial map in the field of so-called low radio frequencies. The astronomers, including Leiden astronomers, used 52 stations with LOFAR antennas spread ...
Harvard & Smithsonian astronomers have detected the first Jupiter-like planet without clouds or haze in its observable atmosphere. The findings were published this month in the Astrophysical Journal Letters. Named WASP-62 b, the gas giant Jupiter-like planet was first detected in 2012 through the Wide Angle Search for Planets (WASP) South survey. Its atmosphere, however, had never been closely studied ...
How dark is space? If you get away from city lights and look up, the sky between the stars appears very dark indeed. Above the Earth’s atmosphere, outer space dims even further, fading to an inky pitch-black. And yet even there, space isn’t absolutely black. The universe has a suffused feeble glimmer from innumerable distant stars and ...
The historic NASA Twins Study investigated identical twin astronauts Scott and Mark Kelly and provided new information on the health effects of spending time in space. Colorado State University Professor Susan Bailey was one of more than 80 scientists across 12 universities who conducted research on the textbook experiment; Mark remained on Earth while Scott orbited high ...
