Astronomers observe predicted supernova explosion

For the first time, a team of astronomers has successfully made observations of a predicted supernova. The enormous cosmic explosion, nicknamed Refsdal, is believed to have occurred roughly 10 billion years ago, and owes its foreshadowing to a rare astronomical phenomenon known as an Einstein Cross, which led to the recent spotting which took place on Dec. 11th.

Astronomers spot enormous twin stars heading for a cataclysmic end

Using the ESO's Very Large Telescope, astronomers have discovered a pair of enormous stars, known as an overcontact binary system, that orbit so close to each other that a bridge of stellar material has formed. Scientists predict that at some point, the strange partnership will end in spectacular fashion, with the stellar bodies either merging to create a single titanic star, or in a violent supernova, that would birth a binary black hole system.

Astronomers observe origin of Type la supernova

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 discover supernova subset which could allow for more acurate galactic measurements

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

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

Astronomers see supernova explosion using galaxies as lenses

A team of astronomers led by the Australian National University (ANU) has discovered a lens of galactic proportions. Using the Hubble Space Telescope and the Keck Observatory in Hawaii, the scientists saw a supernova not once, but four times by using the gravity of a distant cluster of galaxies to act as a natural lens that magnified and quadrupled the image of the exploding star.

Hubble helps find hidden supernova companion

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.
