In recent years, black hole mergers in our universe have been detected via ripples in spacetime known as gravitational waves. Now, for the first time, astronomers believe they've observed visible light from a black hole merger, in a peculiar 3-black-hole system.

Astronomers from Western University in Canada have discovered six more possible exomoons orbiting distant exoplanets, in data from the Kepler Space Telescope.

Astronomers from the University of Göttingen in Germany have discovered two, and possibly three, super-Earth exoplanets orbiting the nearby red dwarf star Gliese-887.

A new study from scientists in the UK suggests that atmospheric dust could increase the habitability of some exoplanets, especially those orbiting red dwarf stars.

On Wednesday, July 1, 2020, 2 astronauts will perform the 2nd of a pair of International Space Station (ISS) spacewalks, to replace aging nickel-hydrogen batteries. How to watch.

Looking for an awesome place to watch meteor showers in the U.S.? AccuWeather - and the editors of EarthSky - recommend these 10 places.

A new study shown by NASA scientists at the Goldschmidt conference this week provides further evidence that Europa's ocean is habitable and similar to Earth's oceans.

Astronomers just announced the most massive quasar yet known in the early universe. Its monster central black hole has a mass equivalent to 1.5 billion of our suns. The object has been given a Hawaiian name, Poniua'ena.

"What if extraterrestrial intelligences are not like us, but are found in the frigid reaches of the outer solar system, the extreme gravity of neutron stars, the brilliant cores of active galaxies, or the hearts of the richest galaxy clusters?"

The science world is buzzing about a new discovery made via the LIGO-Virgo collaboration. It's a new object found in the so-called "mass gap" between neutron stars and black holes.
