On the hunt for 'hierarchical' black holes

Black holes, detected by their gravitational wave signal as they collide with other black holes, could be the product of much earlier parent collisions. Such an event has only been hinted at so far, but scientists believe we are getting close to tracking down the first of these so-called hierarchical black holes.

Hubble finds first evidence of water vapor at Jupiter's moon Ganymede

For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede. This water vapor forms when ice from the moon's surface sublimates - that is, turns from solid to gas.
