ALMA captures sharpest ever view of star formation in the distant universe

By - June 17, 2015 3 Pictures

The Atacama Large Millimeter/submillimeter Array (ALMA) has succeeded in imaging star formation regions in a distant galaxy, with a resolution six times greater than that achievable by the Hubble Space Telescope. The galaxy, dubbed HATLAS J090311.6+003906 or SDP.81, would ordinarily be far too distant to be observed in such impressive detail. However, thanks to an amazing cosmic coincidence, it has fallen foul of a phenomenon known as gravitational lensing, which essentially grants astronomers the opportunity to gaze into the distant past.

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

By - June 1, 2015 3 Pictures

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.

Astronomers observe origin of Type la supernova

By - May 21, 2015 1 Picture

An international team of astronomers from Europe, Israel and the United States has succeeded in shedding light on the origin of Type la supernovae – powerful nuclear explosions in deep space that allow us to chart the vast distances between galaxies. It is known that a white dwarf star is responsible for creating the distinctive, intensely bright explosion, but the cause of the supernovae are still a topic of hot debate.

Astronomers create first 3D image of iconic Pillars of Creation

By - April 30, 2015 2 Pictures
Astronomers from the European Southern Observatory have used data from the Multi Unit Spectroscopic Explorer (MUSE) instrument to compile the first 3D image of the Pillars of Creation, uncovering some key characteristics of the structures in the process. A shot of the magnificent structures composed of interstellar gas was first captured by the Hubble Space Telescope in 1995, and remains one of the most iconic images of space exploration to date.

Astronomers discover supernova subset which could allow for more acurate galactic measurements

By - March 30, 2015 1 Picture
NASA astronomers may have found a way to take more precise measurements of the distances between galaxies. Currently, astronomers use a certain type of supernova, known as a Type la supernova, to gauge the distances between galaxies and from this, the rate at which the universe is expanding. The reason that this particular breed of supernova is singled out for this purpose, is that when they explode, they give out a very similar amount of light. Read More

Astronomers detect star leaving the Milky Way at record speeds

By - March 15, 2015 1 Picture
An international team led by astronomers from Queen's University Belfast has identified the fastest ever star on an escape trajectory from the Milky Way – the white dwarf US708, which is traveling at a staggering 1,200 km per sec (746 miles per sec). The discovery of this star may shed light on the astronomical events that are vital to the calculation of distances in our universe. Read More

Researchers theorize two mechanisms that prevent prolific star creation in galaxy clusters

By - March 11, 2015 1 Picture
For a long time, scientists have been searching for an answer as to how galaxy clusters regulate the number of stars they create. Given that the amount of interstellar gas used to create the stellar giants exists in such abundance, this theoretically allows for the creation of many times the current number of stars. A team of researchers from MIT, Columbia University and Michigan State University believe they have found the answer. Read More
