Despite the name, some black holes effectively “shine” as they suck up nearby material with such force that it begins to glow. New research reveals a new method for detecting these active black holes.

Astronomers watched a pair of pulsars for 16 years to test the theory of general relativity, which has stood unchallenged for over a century.
Plus, the tactics the food industry is using to boost sales of ultra-processed foods in middle-income countries. Listen to The Conversation Weekly.
Most of what we know about planets outside our Solar System relates to gas-giant planets. A new study has identified and characterised a smaller exoplanet.
A partial lunar eclipse during moonrise will let viewers in most Australian capitals see the Moon partly shrouded in Earth’s shadow, while the “Moon illusion” makes it look larger than life.
Such a mission could be developed soon, allowing astrophysicists to take selfies of the solar system and use the Sun’s gravity as a lens to peer deep into space.
After six decades during which it tracked lunar missions, spotted distant pulsars and quasars, and even expanded our concept of the size of the Universe, the Parkes telescope is still going strong.
In 5 billion years the Sun will collapse. A new discovery suggest some planets may still survive afterwards.
The James Webb Space Telescope is set to launch into orbit in December 2021. Its mission is to search for the first light to ever shine in the universe.
Fluctuating radio waves that appear to come from near the heart of the Milky Way are a new puzzle for astronomers.
A key goal of the Chang'e-5 mission was to find evidence of some of the youngest volcanic eruptions on the Moon.
Did we observe the most distant gamma ray burst yet seen, or was it something closer to home?
A new 3D film follows two children as they discover the astrophysical story of the universe and Yamaji stories of the sky and land. Making it was an extraordinary cross-cultural experience.
An astronomer’s guide to all the colours of the sky.
Scientists have a good estimate on the staggering number of stars in the universe.
The largest orbital telescope ever made will allow astronomers to study the atmospheres of alien planets, learn about how stars form in the Milky Way and peer into the farthest reaches of the universe.
Gravity, mass and centrifugal force all contribute to the final shape of a planet.
Preprints are scientific papers made available before being published in a peer-reviewed journal. The Australian Research Council has banned researchers from citing them in grant applications.
By studying the chemical makeup of binary stars, astronomers found many planetary systems are far less peaceful than ours.
The universe has a finite age — 13.8 billion years to be exact. So if it had a beginning, why is it so difficult to say for sure whether it will have an end?
