ESO's VISTA telescope spies hidden Milky Way component

An international team of astronomers has discovered a previously unknown component of the Milky Way – a thin disk of variable stars hidden in the galactic bulge. The observations, made using the ESO's Visible and Infrared Survey Telescope for Astronomy (VISTA) telescope conflict with current theories regarding the composition of the center of our galaxy.Read More

Study suggests an even distribution of elements throughout the universe

A new study carried out by the Japan Aerospace Exploration Agency (JAXA) suggests that when the universe was between two to four billion years old, the elements used to create everything from the largest star to the human race were evenly spread across a vast area of the cosmos. The study focused on an enormous structure of galaxies known as the Virgo Galaxy Cluster, which sits roughly 54 million light years from Earth and harbors over 2,000 galaxies.Read More

Study lends support to prevailing model of Milky Way structure

Results from a new technique designed to map the structure of the Milky Way appear to support the four spiral arm model of our galaxy. A team of researchers from the Federal University of Rio Grande do Sul, Brazil, used data collected by NASA's Wide-field Infrared Survey Explorer (WISE) spacecraft to pinpoint star clusters located in the resource rich environment of the spiral arms, and use them as markers to trace the structure of our galaxy.Read More

Astronomers discover the biggest thing in the Universe

There's some pretty big stuff out there in the Universe, but how big is the biggest? According to a team of Hungarian-US scientists led by Lajos Balazs, the largest regular formation in the Universe is a ring of nine galaxies 7 billion light years away and 5 billion light years wide. Though not visible from Earth, the newly discovered feature covers a third of our sky.Read More

New study tracks the death of our Universe

A new study has measured 200,000 galaxies in an effort to chart the rate at which our Universe is outputting energy, and effectively dying. The study is part of the larger Galaxy And Mass Assembly (GAMA) project, a comprehensive spectroscopic survey seeking to create a model of energy production by the Universe, both in the present day and in times past.Read More

New map reveals a third of the stars in the Milky Way have dramatically changed orbit

It's easy to think of stars as being fixed in place, because that's how we see them in the sky. But like Earth and the other planets, they have orbits. And it turns out those orbits can change dramatically. In creating a new map of the Milky Way as part of the Sloan Digital Sky Survey (SDSS), scientists recently discovered that around 30 percent of the stars in our galaxy have done exactly that – they've moved into a totally new orbit.Read More

Herschel images present a stunning insight into the distribution of matter in our galaxy

Three stunning new images from ESA's Herschel Space Observatory are providing new insights into how matter is distributed in our galaxy. Observations made by the orbital telescope have led astronomers to conclude that our galaxy is threaded with filamentary structures similar to those featured in the newly-released images, the smallest of which stretches across 170 light years of space.Read More
