Using a simple model based on granular physics, like those used for modeling sand or sugar deposits, scientists have recreated the diamond shape of asteroids Ryugu and Bennu
Hycean worlds have hydrogen-rich atmospheres & are covered in oceans, making them prime candidates for the search for life outside our own solar system. #65DaysOfAstro
Based on X-ray detections from the Neil Gehrels Swift Observatory, scientists used the Chandra X-ray Observatory and found rings called light echoes moving out from a black hole and its companion star, reflecting off the surrounding dust clouds.
Using a neutron spectrometer onboard the Dawn spacecraft, scientists have found elevated concentrations of hydrogen in Ceres’ Occator Crater, which provides evidence of an icy crust.
NASA’s TESS spacecraft, which is primarily used to search for exoplanets, has now observed a veritable symphony of pulsating red giant stars, each with their own internal vibrations. More at #365DaysOfAstro
Once again, science has proved Einstein’s theories correct. This time astronomer can see x-ray flashes bent from behind a black hole.
The fossilized remains of methane-cycling microbes have been found in exposed sedimentary seafloor rocks in South Africa. These microbes could extend the fossil record back to when life first began on Earth.
Using data collected by NASA’s Kepler Space Telescope, scientists have found four free-floating, or rogue, planets near the core of the Milky Way.
About 900 million miles away in two different galaxies, a black hole & a neutron star merged, and their gravitational waves have been detected here on Earth. #365DaysOfAstro
The fossilized teeth and bones of baby dinosaurs found in northern Alaska may indicate that dinosaurs didn’t just summer in the Arctic but nested and raised their young there.
