Scientists capture most-detailed radio image of Andromeda galaxy to date

Scientists have published a new, detailed radio image of the Andromeda galaxy - the Milky Way's sister galaxy - which will allow them to identify and study the regions of Andromeda where new stars are born.

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.

Astrophysicist outlines plans for the gravitational wave observatory on the moon

The experiment, dubbed Gravitational-Wave Lunar Observatory for Cosmology, uses the moon's environment and geocentric orbit to analyze mergers of black holes, neuron stars and dark matter candidates within almost 70 percent of the entire observable volume of the universe.
