A star accompanying a rare type of supernova in close orbit has been discovered by astronomers using NASA's Hubble Space Telescope. Confirming a long-held theory that the explosion originated in a binary star arrangement, observations verify that the companion star precipitated the destruction of the aging primary star by drawing off mass until its core collapsed and triggered a supernova event.  Read More

Using an instrument mounted on the European Southern Observatory's (ESO's) Very Large Telescope (VLT), scientists have been able to shed light on some of the mysteries surrounding stardust by observing the event and aftermath of a supernova. The observation was undertaken in an attempt to answer a number of questions regarding stardust, chief of which being where and how the grains are formed and grow. Another oddity that the team hoped to resolve was just how these tiny, fragile particles manage to survive the inhospitable environment that prevails following a supernova.  Read More

Magnetars are extremely dense and highly magnetic neutron stars that can form when a star goes supernova. They are extremely rare, and until now, it has been difficult to determine how and why they form. However, thanks to new data collected by the Very Large Telescope (VLT) at the ESO’s Paranal Observatory in Chile, astronomers believe they have finally solved the great mystery.  Read More

NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) is unraveling the mystery of how stars go supernova by mapping the remnants of radioactive material left in the wake of a supernova. The findings go against previous theories to create a more chaotic view of the conditions prevailing directly before a star explodes.  Read More

The ANU SkyMapper telescope at the Siding Spring Observatory has discovered the oldest kno...

A team of astronomers at The Australian National University (ANU) working on a five-year project to produce the first comprehensive digital survey of the southern sky has discovered the oldest known star in the Universe. Just a 6,000 light year astronomical hop, skip and jump from Earth, the ancient star formed shortly after the Big Bang 13.7 billion years ago.  Read More

A cloudy night in London led to the discovery of the 21st Century's brightest supernova to date. The new supernova 2014J, the brightest since 1993, is located in the galaxy M82. This Type-Ia supernova has just reached its peak brightness of magnitude 10.6. M82 lies at a distance of only about 12 million light years, which explains the brightness of 2014J in our skies. 2014J is bright enough to be seen in small telescopes or perhaps in (very) large binoculars. We'll tell you how to find it.  Read More

Gaia mapping the stars of the Milky Way (Photo: ESA/ATG medialab; background image: ESO/S....

The Gaia mission to map a billion stars in the Milky Way has been delayed for about two months by the European Space Agency. Problems in X-band transponders used in other satellites have begun to appear, and the ESA has decided to replace those modules prior to launching. The likely blastoff date will be in late December of this year.  Read More

Massive galaxy LRG 3-757 forms a gravitational lens for a second galaxy (blue ring) at a d...

Gravitational lenses, which are massive galaxies or galaxy clusters that act as a magnifying glass by bending light passing them, are one of the Universe's golden gifts to astronomers. To help unlock the mysteries that might lie behind these untapped celestial resources, Zooniverse, a program of the Citizens Science Alliance, has begun the Space Warps project. It allows citizen scientists to put their skills at pattern/image recognition to use, toward finding these fugitive gravitational lenses.  Read More

The Nobel Prize in Physics for 2011 has been awarded to three scientists, whose research p...

For almost a hundred years, it has been widely accepted that the Universe is expanding, and that it’s been doing so ever since the Big Bang occurred approximately 14 billion years ago. It was initially assumed that the rate of expansion was slowly declining. What came as a surprise to many scientists, however, was the relatively recent announcement that the rate is in fact increasing. That was the remarkable conclusion reached by three physicists located in two countries, and it has just earned them the Nobel Prize in Physics for 2011.  Read More

Supernova in a jar: 'It is extremely difficult to observe the inside of a real exploding s...

Physicists from the University of Toronto and Rutgers University studying the effects of mixing two reactive chemicals have discovered a new phenomena which mimics the explosion of a type of supernova in miniature. The observation centers around two reactants which create a self-sustaining vortex ring without any external forces or additional catalysts. These kinds of reactions are occurring around us all the time in the atmosphere and oceans as well as stars, but this effect has never been seen and this new ability to study it will help further our understanding of the evolution of the universe.  Read More
