Four of these strange objects have been detected and an international team of astronomers has nicknamed them ORCs - short for "Odd Radio Circles". All four are only visible in radio wavelengths.
The black hole’s mass is about 8,000 times bigger than the black hole in the centre of the Milky Way. If the Milky Way’s black hole wanted to grow that fat, it would have to swallow two thirds of all the stars in our galaxy.
Can a massive star collapse into a black hole without first exploding in a supernova blast? That’s at least one explanation for the disappearance of a star 2.5 mil times brighter than the sun in a dwarf galaxy 75 mil light years away.
The accretion of new material during Pluto's formation may have generated enough heat to create a liquid ocean that has persisted beneath an icy crust to the present day.
Groups like Mars Habitat are dedicated to conducting simulated missions in analog environments. The lessons learned will not only prepare people to live and work in space but foster ideas for sustainable living here on Earth.
Magnetars generate the absolute most powerful magnetic fields the cosmos has ever seen – and astronomers have recently spotted a newborn. It appears to be the youngest- ever magnetar ever detected.
The Solar Orbiter project, a collaboration between the European Space Agency and NASA, has begun a critical new stage of the mission after the probe's first close encounter with the Sun.
XENON1T data from 2017-2018 has revealed an unexpected excess of low-energy interactions with the xenon’s electrons, more than the Standard Model of particle physics would predict.
An Earth-like world is one that’s rocky and that orbits a Sun-like, or G-Type, star. The Milky Way has 400 billion stars, with 7 % of them being G-type, meaning that less than six billion stars may have Earth-like planets in our Galaxy.
Astronomers have discovered that emissions from an object known as a repeating Fast Radio Burst follow a cyclic pattern repeating every 157 days.
A recent study shows that Titan is drifting further and further from Saturn. And the rate at which it’s drifting is 100 times faster than expected. This suggests that Titan has been migrating to its current distance for 4.5 bil years.
For the first time, scientists have measured the lifespan of a neutron in the void of space. This could help us to better understand how quickly elements formed out of the particle soup that filled the Universe just after the Big Bang.
A recent UK study shows that there could be about 36 active communicating intelligent civilizations in our home Galaxy. This is an enormous advance over previous estimates which spanned from zero to billions.
The ringless Mars we see today is probably an anomaly. We’re in between rings right now, and we’ve assumed that’s normal.
The red dwarf Proxima Centauri, just 4.2 lights years away. Recently, U.S. astronomers using data collected from the Hubble Space Telescope 25 years ago, have confirmed the presence of an exoplanet Proxima Centauri c.
