A new international study, led by an Australian researcher from the ARC Centre of Excellence for Gravitational Wave Discovery, searched for elusive continuous gravitational waves…
Multimessenger astronomy is an emerging field that aims to study astronomical objects using different ‘messengers’ or sources, like electromagnetic radiation (light), neutrinos, and gravitational waves….
The first evidence of the existence of black holes was found in the 1960s, when strong X-rays were detected from a system called Cygnus X-1….
Gravitational waves are cosmic ripples in the fabric of space and time that emanate from catastrophic events in space, like collisions of black holes and…
Many of the heaviest stars in the Universe will end their lives in a bright explosion, known as a supernova, which briefly outshines the rest…
Key points: An international team of scientists, including Australian researchers from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav), have collaborated on a…
With the growing catalog of binary black hole mergers, researchers can study the overall spin properties of these systems to uncover how they formed and…
Our Universe shines bright with light across the electromagnetic spectrum. While most of this light comes from stars like our Sun in galaxies like our…
On August 17th, 2017, LIGO detected gravitational waves from the merger of two neutron stars. This merger radiated energy across the electromagnetic spectrum, light that…
Binary neutron stars have been detected in the Milky Way as millisecond pulsars and twice outside the galaxy via gravitational-wave emission. Most of them have…
In the 2030’s, gravitational-wave detectors will be thousands of times more sensitive than Advanced LIGO, Virgo, and KAGRA. The network of “third generation” (3G) observatories…
Short gamma-ray bursts are extremely bright bursts of high-energy light that last for a couple of seconds. In many of these bursts, there is a…
Galaxies host supermassive black holes, which weigh millions to billions of times more than our Sun. When galaxies collide, pairs of supermassive black holes at…
Making Waves at the Museum Exhuibit modeled after a real-life gravitational-wave detector to explain gravitational-wave science. It was developed by an international team, which includes…
‘Type Ia’ supernovae involve an exploding white dwarf close to its Chandrasekhar mass. For this reason, type Ia supernova explosions have almost universal properties and…
BepiColombo is a joint mission between the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) designed to study the planet Mercury. Launched…
Gamma-ray bursts are enormous cosmic explosions and are one of the brightest and most energetic events in the Universe. Their brightness changes over time, illuminating…
What happens if a supernova explosion goes off right beside another star? The star swells up, which scientists predict as a frequent occurrence in the…
