NASA’s Swift Sees ‘Wandering’ Mega Black Hole Shredding Star
NASA’s Neil Gehrels Swift Observatory captured an “orphan” black hole lighting up as it devoured a star on the outskirts of a faraway galaxy. These phenomena are rare to begin with, and none had ever before been seen so far outside of a galaxy’s core. “We were looking for these star-shredding events as a way to find otherwise invisible supermassive…

NASA’s Hubble Shows Star Formation in Andromeda Galaxy Winding Down
A new study using data from NASA’s Hubble Space Telescope finds that star formation in the nearby Andromeda galaxy has undergone a 500-million-year decline, with an even steeper drop in the last 40 million years. Andromeda, a spiral galaxy comparable in size to our Milky Way, is close enough to be seen with the unaided eye from areas with dark skies. Located…

NASA’s ESCAPADE Snaps Family Portrait of Earth, Moon
On July 3, one of NASA’s two Mars-destined ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) spacecraft captured photos of Earth and the Moon in visible and thermal infrared light. At the time, the spacecraft was 363,250 miles (584,600 kilometers) from Earth and 115,600 miles (186,100 kilometers) from the Moon, making the Moon appear relatively large. Taken with the Sun…
