Binary stars form lots of exoplanets, but many of them are ejected as rogue...
Astronomers don't have to work hard to find binary stars in the Milky Way.
They're common, even abundant. For a long time, they thought that...
Scientists turn electricity into sound in breakthrough quantum device
Scientists have created a new kind of quantum device that can turn electricity into something unusual: tiny packets of sound known as phonons.
This breakthrough...
Scientists finally discover the true edge of the Milky Way
For many years, astronomers have wondered where the Milky Way truly “ends.” Unlike a solid object, our galaxy does not have a clear boundary.
Its...
Astronomers find the edge of the Milky Way’s star-forming disc
Where exactly is the edge of the Milky Way?
That question is harder to answer than one might expect. Since we’re inside of the galaxy...
Young sun-like stars are not as menacing as thought
Scientists know that the behaviour of stars can dictate planetary habitability.
Research shows that young stars emit powerful radiation that can strip planetary atmospheres away.
And...
Cosmic dances reveal the true weight of young stars in Orion
A star’s mass decides almost everything about its life, from how bright it shines to how it eventually dies.
But for young stars hidden deep...
Exploding stars, black holes, and the forbidden gap
When the first gravitational wave (GW) was detected back in 2015, scientists said they had opened a new window into the Universe.
While most of...
How a black hole and a shredded star could light up a galaxy
In 2014, a strange cloudy object called G2 made a close approach to Sagittarius A*, (Sag A*) the supermassive black hole at the heart...
Two monsters, one galaxy, and a collision 100 years away!
Space is full of objects that push the boundaries of imagination, but few do it quite as effectively as a black hole.
At its simplest,...
It’s not supposed to be like this: A giant planet orbits a small star
The nebular hypothesis states that stars and the planets that orbit them form from the same reservoir of material, called a solar nebula.
It's the...
