As more and more exoplanets are discovered throughout the galaxy, scientists find some that defy explanation—at least for awhile. A new study, published in Nature, describes a process that might explain why a large portion of exoplanets have water on their surface, even when it doesn’t make sense. Go to Source Why is it important to know about exoplanets having their atmospheres stripped while orbiting F-type stars? This is what a recent study submitted to The Astronomical Journal hopes to address as an international team of scientists conducted a first-time investigation into atmospheric escape on planets orbiting F-type stars, the latter of which are larger and […] The crew for China’s next manned flight to its space station will include the country’s youngest astronaut to undertake a space mission, authorities said Thursday, as well as four lab mice. Go to Source As a kid, did you ever play that game Guess Who? If you haven’t, it’s actually kinda fun. You have two players, each with a board in front of them. On the board are a bunch of flip cards with different characters. You have to guess your opponent’s secret identity through a process of elimination. […] Using NASA’s Swift spacecraft, an international team of astronomers have performed X-ray observations of a classical nova named Nova Scorpii 2023. Results of the observational campaign, published October 21 on the pre-print server arXiv, deliver important insights into the properties and behavior of this eruption. Go to Source Using NASA’s Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers have detected a new exoplanet orbiting a bright K-type star known as TOI-283. The newfound alien world, which received the designation TOI-283 b, is about 40% smaller than Neptune. The discovery was detailed in a research paper published October 16 on the pre-print […] Every year, the Taurid meteor shower lights up the night sky from late October through early November. Sometimes called the “Halloween fireballs,” they are named for the constellation Taurus—the bull—from which the meteors appear to radiate. The shower is best viewed from dark-sky locations. Go to Source China said Thursday it’s on track to land astronauts on the moon by 2030 as it introduced the next crew of astronauts who will head to its space station as part of the country’s ambitious plans to be a leader in space exploration. Go to Source Our moon—or la Luna—has inspired humankind for millennia. Go to Source The Milky Way is a rich and complex environment. We see it as a luminous line stretching across the night sky, composed of innumerable stars. Go to Source The Habitable Worlds Observatory (HWO) is slated to be the next Great Observatory for the world. Its main focus has been searching for biosignatures in the atmospheres of at least 25 Earth-like exoplanets. However, to do that, it will require a significant amount of effort with only a coronagraph, the currently planned primary instrument, no […] A new study into how spaceflight impacts the human brain and eyes revealed notable sex differences in brain fluid shifts, with female astronauts showing a greater reduction in fluid around the uppermost part of the brain than their male counterparts. Go to Source A new analysis of chemical signatures measured by NASA’s Curiosity Rover gives a peek at Mars’s past to a time some 3.7 billion years ago, when it was warmer and wetter. Go to Source Mars is an inhospitable desert planet. Billions of years ago, things were different. In Jezero Crater, for example, fed by a vast river delta, there was probably a considerable body of water roughly the size of Lake Constance. Conditions conducive to life may have prevailed there. Go to Source For the first time, scientists have the calculations and simulations to explain mysterious flashes from the galaxy OJ 287. Roughly twice every 12 years, from 3.5 billion light years away, the light equivalent of 1 trillion suns flashes in the night sky and then fades away over the next few months. It’s a phenomenon that […] |
