Galactic pyrotechnics on display in nearby galaxy

By - July 3, 2014 2 Pictures
As the US prepares for 4th of July fireworks here on Earth, a nearby spiral galaxy similar to our Milky Way is putting on a pyrotechnics display of its own. The galaxy, NGC 4258 (also known as Messier 106 or M 106), is ejecting gas and high-energy particles in a spectacular display of power that is rippling across the face of the galaxy with shock waves of stellar energy.

First images from the CSIRO's ASKAP radio telescope

By - June 11, 2014 3 Pictures
In preparation for the Square Kilometer Array (SKA) radio telescope project set to start construction in 2018, the CSIRO’s recently unveiled Australia SKA Pathfinder (ASKAP) radio telescope array has been used to demonstrate and prove the technology involved. With the images it has captured so far, it has also shown its ability to operate as a fully-fledged radio telescope in its own right. Read More

NASA creates artificial stardust

Carl Sagan once said, “We are made of starstuff.” Unfortunately, he was a bit vague about what this starstuff actually is. To help answer that question, scientists at NASA’s Ames Research Center in California have developed a way of recreating the dust and gas found around dying red giant stars that eventually become planet-forming interstellar dust.

Illustris computer simulation creates the first realistic virtual universe

By - May 7, 2014 3 Pictures
As you might expect, the scale and complexities of the underlying physics means creating a realistic virtual universe would require some hefty computing power. A team of astronomers is claiming to have achieved this impressive feat using a computer simulation called "Illustris," which took five years to program and, for the first time, can recreate the evolution of the Universe in high fidelity.

Caught on video: Asteroid impacts on Moon's surface

By - February 25, 2014 1 Picture
A meter-wide (3 ft) asteroid impacted the Moon's surface September 11, 2013, producing a bright explosion and digging a new crater about 40 meters (130 ft) in diameter. The video of the event shows a bright flash of light against the stark blackness of the Moon's dark side. Similar in brilliance to the brightest stars in the Big Dipper, the asteroid impact is the largest confirmed impact on the Moon since continuous monitoring started some 15 years ago. Read More

Oldest known star in the Universe discovered

By - February 10, 2014 2 Pictures
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

The M82 supernova is at peak brightness: How to see it

By - January 31, 2014 5 Pictures
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
