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.
Two seemingly unrelated stars, each with several exoplanets, turn out to be members of an enormous, diffuse star cluster. Plus, baby squid go to the ISS, new images from China’s Zhurong rover, a brightening blazar, and an interview with scientist Sophia Gad-Nasr and artist Cathrin Machin about how art and science work together.
Scientists examined the populations of stars observed by the Kepler and K2 missions and found that the solar systems were different depending on the type of star involved.
New research shows that our galaxy was already in place prior to a major collision with a dwarf galaxy ten billions years ago. Plus a science review of Godzilla vs. Kong. No. Really! #365DaysOfAstro
