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.

Cosmic oddball

P/2013 P5 is an atypical asteroid which rotates so rapidly that it loses mass and thus forms several tails.

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.

Astronomers find black hole in globular cluster

Last year when a team of astronomers led by a Michigan State University professor discovered two black holes in a collection of stars known as a globular cluster, they weren't sure if their presence was a common occurrence or a unique stroke of luck.

Astronomers establish the strength of high-inclination asteroids

A team of astronomers from the National Astronomical Observatory of Japan and the University of Hyogo used the Subaru Prime Focus Camera (Suprime-Cam) mounted on the Subaru Telescope to observe faint asteroids with highly inclined orbits. They found that a smaller fraction of tiny bodies occur among high-inclination asteroids than those near the ecliptic plane.

White dwarfs hide information on dark forces

Researchers from Europe and the USA have ruled out a multitude of possible parameters for dark photons - a type of dark matter and energy - with the help of white dwarfs. In some aspects, the shining of these dying stars gives more information on dark forces than is provided by earth-based laboratories.
