Newly discovered black holes in dwarf galaxies shed light on the origin of our galaxy's central supermassive black hole.

The Andromeda galaxy, our Milky Way's closest neighbor, is the most distant object in the sky that you can see with your unaided eye.

Planetary systems around binary stars may be very different from those around single stars and might point to extraterrestrial life.

Astronomers have been able to identify the widest range of elements in a relatively bright star beyond our solar system yet.

Astronomers have identified a rapidly growing black hole in the early universe that is considered a crucial "missing link".

Astronomers have found a slimmer type of red giant star for the first time. These stars have undergone dramatic weight loss.

Astronomers identified a number of stellar streams from past mergers years ago, and also used globular clusters to construct a timeline.

Our galaxy is a giant ‘smoothie’ of blended stars and gas but a new study tells us where the components came from.

A team of German astronomers have discovered a strange new type of star covered in the by-product of helium burning.

A team of space scientists has published a paper suggesting that there may be an Earth or Mars-sized planet orbiting beyond Neptune.

Scientists found something unusual that releases a giant burst of energy 3 times an hour, and unlike anything astronomers have seen before.

The Earth sits in a 1,000-light-year-wide void surrounded by thousands of young stars — but how did those stars form?

Astronomers spying on a stellar system located dozens of lightyears from Earth have, for the first time, observed a troubling fireworks show

Planets known as eggshell planets, which orbit distant stars, have ultra-thin crusts too thin to sustain tectonics and are hostile to life.

A team of international scientists have unveiled the largest number of gravitational waves ever detected.

A NASA sounding rocket will observe a nearby star to learn how starlight affects the atmospheres of exoplanets in the hunt for life.

Studying the atmospheres of white dwarfs that have been “polluted” by such debris, researchers have identified exotic rock types.

Astronomers have reported the discovery of a structure thought to be a "protocluster" of galaxies 11 billion light-years from Earth.

Astronomers have discovered the very first confirmed planetary system that resembles the expected fate of our solar system.

Scientists have discovered stars unexpectedly blasting out radio waves, possibly indicating the existence of hidden planets.
