Hubble reveals first scrapbook pictures of Milky Way's formative years

The Hubble Space Telescope has provided the first visual evidence showing how our home galaxy, the Milky Way, assembled itself into the majestic pinwheel of stars we see today. Perusing Hubble's deep-sky surveys, astronomers traced 400 galaxies similar to our Milky Way at various stages of construction over a time span of 11 billion years.

New theoretical models aid the search for Earth-like planets

Researchers from Bern have developed a method to simplify the search for Earth-like planets: By using new theoretical models they rule out the possibility of Earth-like conditions, and therefore life, on certain planets outside our solar system - and limit their search by doing so.

Young stars paint spectacular stellar landscape

Astronomers at ESO have captured the best image so far of the clouds around the star cluster NGC 3572. This image shows how these clouds of gas and dust have been sculpted into bubbles, arcs and the odd features known as elephant trunks by the stellar winds flowing from this gathering of hot stars. The brightest of these cluster stars are much heavier than the Sun and will end their short lives as supernova explosions.

Mission to Mars moon could be a sample-return twofer, study suggests

Brown researchers have helped to confirm the idea that the surface of Phobos contains tons of dust, soil, and rock blown off the Martian surface by large projectile impacts. That means a sample-return mission planned by the Russian space agency could sample two celestial bodies for the price of one.

Hubble catches stellar explosions in NGC 6984

The subject of this new Hubble image, spiral galaxy NGC 6984, played host to one of these explosions back in 2012, known as SN 2012im. Now, another star has exploded, forming supernova SN 2013ek.

From 1 collapsing star, 2 black holes form and fuse (w/video)

Over billions of years, small black holes can slowly grow into supermassive black holes by taking on mass from their surroundings, and also by merging with other black holes. But this slow process can't explain how supermassive black holes existing in the early universe would have formed less than one billion years after the Big Bang. New findings from a group of Caltech researchers help to test a model that solves this problem.
