Novel vision of the death of massive stars

An international consortium has published in a single article a compendium of data obtained after the simultaneous research of three supernovas and of their corresponding Gamma-Ray Bursts (GRB). The research enabled contrasting statistically that the supernovas associated with GRB emit greater quantities of nickel compared to those not linked to GRB.

Volunteer 'Disk Detectives' top 1 million classifications of possible planetary habitats

A NASA-sponsored website designed to crowdsource analysis of data from the agency's Wide-field Infrared Survey Explorer (WISE) mission has reached an impressive milestone. In less than a year, citizen scientists using DiskDetective.org have logged 1 million classifications of potential debris disks and disks surrounding young stellar objects (YSO). This data will help provide a crucial set of targets for future planet-hunting missions.

'Iron Sun' is not a rock band, but a key to how stars transmit energy

Working at temperatures matching the interior of the sun, researchers at Sandia National Laboratories' Z machine have been able to determine experimentally, for the first time, iron's role in inhibiting energy transmission from the center of the sun to near the edge of its radiative band - the section of the solar interior between the sun's core and outer convection zone.

Milky Way core drives wind at 2 million miles per hour

At a time when our earliest human ancestors had recently mastered walking upright, the heart of our Milky Way galaxy underwent a titanic eruption, driving gases and other material outward at 2 million miles per hour. Now, at least 2 million years later, astronomers are witnessing the aftermath of the explosion: billowing clouds of gas towering about 30,000 light-years above and below the plane of our galaxy.

Super-Earths have long-lasting oceans

For life as we know it to develop on other planets, those planets would need liquid water, or oceans. Geologic evidence suggests that Earth's oceans have existed for nearly the entire history of our world. But would that be true of other planets, particularly super-Earths? New research suggests the answer is yes and that oceans on super-Earths, once established, can last for billions of years.

Stars' spins reveal their ages

When you're a kid every birthday is cause for celebration, but as you get older they become a little less exciting. You might not want to admit just how old you are. And you might notice yourself slowing down over the years. You're not alone - the same is true of stars. They slow down as they age, and their ages are well-kept secrets. Astronomers are taking advantage of the first fact to tackle the second and tease out stellar ages.

New instrument reveals recipe for other Earths

How do you make an Earth-like planet? The 'test kitchen' of Earth has given us a detailed recipe, but it wasn't clear whether other planetary systems would follow the same formula. Now, astronomers have found evidence that the recipe for Earth also applies to terrestrial exoplanets orbiting distant stars.

Scientists predict earth-like planets around most stars

Planetary scientists have calculated that there are hundreds of billions of Earth-like planets in our galaxy which might support life, by applying a 200 year old idea to the thousands of exo-planets discovered by the Kepler space telescope.

A simulation of the universe with realistic galaxies

An international team of astronomers developed a simulation of the universe in which realistic galaxies are created; their mass, size and age are similar to those of observed galaxies. Their similarity is caused by the simulation of strong galactic winds - gas winds that are blown from galaxies.

Scientists 'map' water vapor in Martian atmosphere

Scientists have created a 'map' of the distribution of water vapour in Mars' atmosphere. Their research includes observations of seasonal variations in atmospheric concentrations using data collected over ten years by the SPICAM spectrometer aboard the Mars Express orbiter.

The Milky Way's new neighbour

The Milky Way, the galaxy we live in, is part of a cluster of more than 50 galaxies that make up the 'Local Group', a collection that includes the famous Andromeda galaxy and many other far smaller objects. Now a Russian-American team have added to the canon, finding a tiny and isolated dwarf galaxy almost 7 million light years away.
