Evidence found for granite on Mars

Researchers now have stronger evidence of granite on Mars and a new theory for how the granite - an igneous rock common on Earth - could have formed there, according to a new study. The findings suggest a much more geologically complex Mars than previously believed.

Scientists document, quantify deep-space radiation hazards

Scientists from the University of New Hampshire and colleagues have published comprehensive findings on space-based radiation as measured by a UNH-led detector aboard NASA's Lunar Reconnaissance Orbiter (LRO). The data provide critical information on the radiation hazards that will be faced by astronauts on extended missions to deep space such as those to Mars.

Hubble views an old and mysterious cluster

The Hubble Space Telescope has captured the best ever image of the globular cluster Messier 15, a gathering of very old stars that orbits the center of the Milky Way. This glittering cluster contains over 100 000 stars, and could also hide a rare type of black hole at its center.

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.
