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

This would be a eureka moment because it would change physics as we know it and expand our understanding of the universe.

Research conducted aboard the International Space Station is helping scientists answer questions about the formation of the universe

How can Einstein's theory of gravity be unified with quantum mechanics? This is a challenge that could yield deep insights into black holes.

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

When tiny galaxies collide with bigger ones, the bigger galaxies can strip the smaller galaxies of their dark matter which we can’t see.

Black holes are more than just massive objects that swallow everything around them—they're also one of the universe's biggest energy sources

Researchers in Australia say their latest project scanned billions of stars and 144 known exoplanets for signs of alien broadcasts.

Physicists looked at specific features of light to figure out the closest you can get to a black hole without having to prevent disaster.

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

How many black holes are out there in the Universe? This is one of the most relevant and pressing questions in modern cosmology.

Among other goals, James Webb will search the atmospheres of alien planets for what scientists call "biosignatures" -- the presence of life.

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

Researchers present a numerical estimate for the amount of encoded information in all the visible matter in the universe.

For astronomers, the ability to observe the Cosmic Dawn represents an opportunity to answer the most enduring cosmic mysteries.

An international team of researchers has generated an entire virtual universe, and made it freely available on the cloud to everyone.

The history of life on Earth has often been likened to a four-billion-year-old torch relay. One flame, lit at the beginning of the chain.

Researchers from University of Copenhagen have investigated what happened to a specific kind of plasma - the first matter ever to be present

NASA’s new telescope has a considerable mission on its hands: to peer deeper into space and further back in time than ever before

From an observatory high above Chile's Atacama Desert, astronomers have taken a new look at the oldest light in the universe.
