Catastrophic floods rapidly carved the surface of Mars

Astronomy Magazine - Mon, 11/19/2018 - 05:00
Catastrophic Flooding More than 3.5 billion years ago, water flowed freely across the surface of Mars, forming lakes and seas. New research shows how these lakes may have overflowed and burst at their sides, causing flooding so severe it carved out canyons in the Martian surface over the course of just weeks. This new research suggests that the flooding could have drastically shaped and altered the Martian landscape and, potentially, other planets that similarly lack plate tectonics, lead auth

Ultra-bright galaxy feeds its black hole by ripping material from neighbors

Astronomy Magazine - Mon, 11/19/2018 - 05:00
In the early days of our universe, the gravity of an ultra-bright galaxy pulled streams of dust and gas from nearby galaxies to power its supermassive black hole and associated bright quasar. Now, for the first time ever, researchers have observed this cosmic interaction. When gravitational forces shepherd material like dust and gas into a supermassive black hole at the center of a galaxy, that material grinds together and emits energy that’s observed as a quasar. A quasar is the active c

There’s a frozen super-Earth orbiting Barnard’s star, the second-closest star system

Astronomy Magazine - Wed, 11/14/2018 - 05:00
Just six light-years from Earth, the second-closest star system to our Sun hosts a frozen super-Earth, according to new findings by an international team of researchers. Barnard’s star is a small, ancient kind of sun called a red dwarf. And while it’s not easily visible without a telescope, Barnard’s star has long attracted astronomers' gaze as the fastest-moving star in the night sky. Astronomers now say it’s also home to a frozen exoplanet at least three times as massi
