Gas-giant exoplanets cling close to their parent stars

Gemini Observatory's Planet-Finding Campaign finds that, around many types of stars, distant gas-giant planets are rare and prefer to cling close to their parent stars. The impact on theories of planetary formation could be significant.

Researchers help launch 3-D printing into space

Researchers at Washington State University are working with Aerojet Corporation on an exploratory project to make custom satellite parts using 3-D printing. Lower costs, less waste, quicker turnaround and easier modification are some potential benefits.

Spiral galaxies like Milky Way bigger than thought

Spiral galaxies like our own Milky Way appear to be much larger and more massive than previously believed, according to a new University of Colorado Boulder study by researchers using the Hubble Space Telescope.

Zooming in on the black hole

Astronomers have gathered the most detailed observations ever into the surroundings of the supermassive black hole at the centre of an active galaxy, and made a surprising discovery: dust is being propelled into space in a ring-shaped disk.

The violent birth of neutron stars

A team of researchers at the Max Planck Institute for Astrophysics conducted the most expensive and most elaborate computer simulations so far to study the formation of neutron stars at the center of collapsing stars with unprecedented accuracy.

First transiting planets in a star cluster discovered

All stars begin their lives in groups. Most stars are born in small groups that quickly fall apart. Others form in huge, dense swarms, where stars jostle with thousands of neighbors while strong radiation and harsh stellar winds scour interstellar space, stripping planet-forming materials from nearby stars. It would thus seem an unlikely place to find alien worlds. Yet 3,000 light-years from Earth, in the star cluster NGC 6811, astronomers have found two planets smaller than Neptune orbiting sun-like stars.

Three planets in habitable zone of nearby star

A team of astronomers has combined new observations of Gliese 667C with existing data from HARPS at ESO's 3.6-meter telescope in Chile, to reveal a system with at least six planets. A record-breaking three of these planets are super-Earths lying in the zone around the star where liquid water could exist, making them possible candidates for the presence of life. This is the first system found with a fully packed habitable zone.

Revealed - the mystery of the gigantic storm on Saturn

We now understand the nature of the giant storms on Saturn. Through the analysis of images sent from the Cassini space probe belonging to the North American and European space agencies (NASA and ESA respectively), as well as the computer models of the storms and the examination of the clouds therein, the Planetary Sciences Group of the University of the Basque Country has managed to explain the behaviour of these storms for the very first time.

Astronomers spy on galaxies in the raw

A CSIRO radio telescope has detected the raw material for making the first stars in galaxies that formed when the Universe was just three billion years old - less than a quarter of its current age. This opens the way to studying how these early galaxies make their first stars.

Solar splashdown

On June 7, 2011, our sun erupted, blasting tons of hot plasma into space. Some of that plasma splashed back down onto the sun's surface, sparking bright flashes of ultraviolet light. This dramatic event may provide new insights into how young stars grow by sucking up nearby gas.

Hubble spots galaxies in close encounter

When two galaxies stray too close to each other they begin to interact, causing spectacular changes in both objects. In some cases the two can merge - but in others, they are ripped apart.

Dusty surprise around giant black hole

New observations of a nearby active galaxy called NGC 3783, harnessing the power of the Very Large Telescope Interferometer (VLTI) at ESO's Paranal Observatory in Chile, have given a team of astronomers a surprise. Although the hot dust - at some 700 to 1000 degrees Celsius - is indeed in a torus as expected, they found huge amounts of cooler dust above and below this main torus.

Metamorphosis of moon's water ice explained

Using data gathered by NASA's Lunar Reconnaissance Orbiter (LRO) mission, scientists believe they have solved a mystery from one of the solar system's coldest regions - a permanently shadowed crater on the moon.
