Studying spaceflight atrophy with machine learning

Even intense exercise by astronauts cannot compensate for muscle atrophy caused by microgravity. Atrophy occurs, in part, by way of an underlying mechanism that regulates calcium uptake. Recent research has shown exposure ...

Most massive stellar black hole in our galaxy found

Astronomers have identified the most massive stellar black hole yet discovered in the Milky Way galaxy. This black hole was spotted in data from the European Space Agency's Gaia mission because it imposes an odd 'wobbling' ...

In search for alien life, purple may be the new green

From house plants and gardens to fields and forests, green is the color we most associate with surface life on Earth, where conditions favored the evolution of organisms that perform oxygen-producing photosynthesis using ...

Astronomers inspect open cluster Berkeley 50

Using the Lowell Discovery Telescope (LDT), astronomers from the Lowell Observatory in Flagstaff, Arizona, have observed a young Galactic open cluster known as Berkeley 50. Results of the observational campaign, presented ...

NASA's Fermi mission sees no gamma rays from nearby supernova

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA's Fermi Gamma-ray ...
