An Exoplanet Orbiting A Baby Star

NASA’s Transiting Exoplanet Survey Satellite (TESS) has made a remarkable discovery while studying the baby star “AU Mic” – it has an exoplanet about the same distance as Neptune is from our star.

Black Hole Discoveries

While LIGO and Virgo are detecting gravitational waves of a black hole potentially swallowing a tiny neighbouring object, astronomers have spotted the biggest quasar way out in the depths of the early universe.

A Hot Start for Pluto

At the beginning of the solar system Pluto may have been bombarded by rocky material in much the same way as the inner planets. That means, according to researchers, there may be an ocean locked away under the surface…

Starlink Tests Begin

SpaceX’s Starlink has put the call out for members of the public to test their network but the catch is only folks in the far northern hemisphere have access, but the speeds potentially on offer are astronomical..

A Busy Weekend of Rocket Launches

Last weekend was a busy one for low Earth orbit. Three private companies attempted to launch three separate rockets into orbit – and while only SpaceX & Rocket Lab were successful, the Japanese attempt marked a step forward in their endeavour.

Almost a Perfect Clone

Astronomers have stumbled on what could be mistaken for a clone of our own solar system. And while the discovery is yet to be confirmed, all signs are promising for this find.

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.
