A Fast and Weird White Dwarf Star

Astronomers have discovered a very peculiar white dwarf star about 150 light years away, it’s mass is double the average and it’s moving 99% faster than any of it’s neighbours.

Another Big Bang

Astronomers have discovered the biggest explosion we have ever seen. They spotted the remnants of this blast in the Ophiuchus galaxy cluster, most likely from a supermassive black hole using the Murchison Widefield Array and NASA’s Chandra X-ray Observatory.

The Slowest Rotating ‘Cosmic Lighthouse’ Yet Discovered

Distant neutron stars typically spin a full 360 degrees within seconds. However, a new type of ‘radio transient object’ – so called as they are detected in radio waves – has emerged that rotate much more slowly. In the time it takes this cosmic lighthouse to rotate you could watch Interstellar twice before it completes a full spin.

Mapping Ripples In A Cosmic Ocean

An international study led by Australian astronomers has created the most detailed maps of gravitational waves across the universe to date in three new research papers. The study also produced the largest ever galactic-scale gravitational wave detector and found further evidence of a “background” of these invisible yet incredibly fast ripples in space that can help unlock some major mysteries of the universe.

How Saturn’s Rings Might Be Keeping A Youthful Appearance

Even though Saturn’s rings appear clean and young, they may be as old as the planet itself according to international researchers. It was previously thought that impacts with small rocky debris travelling through space – called micrometeoroids – would dirty and darken the rings over time, but in 2004 the Cassini spacecraft revealed the rings to be clean and bright suggesting that they are not very old.
