The LIGO and Virgo observatories have detected gravitational waves caused by the collision of a black hole, accompanied by a mysterious astrophysical object.
Astronomers have observed the full process of material spiralling into a distant neutron star, triggering an X-ray outburst thousands of times brighter than our Sun.
Exactly how massive galaxies attain their size is poorly understood, but now a combination of observation and modelling has provided a vital clue.
A star that pulsates on just one side has been discovered in the Milky Way — and while such stars have been predicted in theory, this is the first of its kind to be recorded.
Starquakes recorded by NASA's now-defunct Kepler space telescope have helped answer a longstanding question about the age of the 'thick disc' of the Milky Way.
Researchers were excited by the discovery of a stellar black hole with a mass 70 times that of the Sun, located 15,000 light years from Earth.
It is now possible for materials researchers to make quick predictions about how certain elements will behave at different pressures.
A newly discovered ancient star, containing what is said to be a record-low amount of iron, carries evidence of a class of even older stars.
Astronomers have determined the precise location of a powerful one-off burst of cosmic radio waves, thanks to the Australian Square Kilometre Array Pathfinder radio telescope.
Astronomers have discovered rapidly swinging jets coming from a black hole almost 8000 light-years from Earth — behaviour that has never before been observed on such short timescales.
How will the Morrison Government's pre-election 2019 Federal Budget impact science and research?
Russian physicists have found a way to wind back the clock, returning the state of a quantum computer a fraction of a second into the past.
Using CSIRO's ASKAP radio telescope, researchers have witnessed what they claim is the beginning of the end for one of the Milky Way's neighbouring galaxies.
Astronomers have revealed that the Milky Way's disc of stars becomes increasingly 'warped' and twisted the further away the stars are from the galaxy's centre.
Researchers have developed a high-throughput RNA sequencing strategy to study the activity of the gut microbiome.
