A new study suggests that many more planets may have large amounts of water than previously thought - as much as half water and half rock. All that water is probably embedded in the rock, rather than flowing as oceans.
The astronomers underlined that the star, these planets are orbiting is the second-coolest star found to host planets after TRAPPIST-1. They added that their finding is the second-most favorable habitable-zone terrestrial planet known so far.
A machine called MOXIE, stowed away on NASA’s Perseverance rover, can reliably convert carbon dioxide into a small tree’s worth of oxygen. During various tests, MOXIE steadily breathed in Martian atmosphere and breathed out at least six grams of oxygen an hour.
The exoplanet is a gas giant, meaning it has no rocky surface and could not be habitable. The image shows how Webb's powerful infrared gaze can easily capture worlds beyond our solar system.
The Chinese Academy of Science (CAS) has recently reported successfully growing rice and vegetables on the Tiangong space station.
This observation of a gas giant planet orbiting a Sun-like star 700 light-years away provides important insights into the composition and formation of the planet.
It's called TOI-1452b, and measurements of its size and mass suggest a density profile consistent with a global liquid ocean. An exoplanet is just 100 light-years from Earth
Australian astronomers have discovered one of the biggest black hole jets in the sky. Spanning more than a million light years from end to end, the jet shoots away from a black hole with enormous energy, and at almost the speed of light.
An international team of researchers studying dust samples retrieved by the Hayabusa-2 space probe, has found that some of its dust grains are older than the solar system.
The aftermath of an epic collision involving at least one neutron star has been captured for the first time in the millimeter range of radio frequency wavelengths.
Scientists have proved that the source of high-energy neutrinos is a special kind of supermassive black holes called blazars.
Far out in the Milky Way, roughly 22,000 light years from Earth, a star unlike any other roars with a magnetic force that beats anything physicists have ever seen.
Not only was it very long, lasting about three seconds, but there were periodic peaks that were remarkably precise, emitting every fraction of a second – like a heartbeat. This is the first time the signal itself is periodic.
The first full-color image from NASA's James Webb Space Telescope has been released. The images are be the deepest and highest resolution ever taken of the universe, according to NASA.
NASA's James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb'nas First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.
