New research suggests an unseen ‘mirror world’ of particles might be the key to solving a major puzzle in cosmology – the Hubble constant.

A unique new instrument, coupled with a powerful telescope and a little help from nature, enables scientists to peer into galactic nurseries

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

A futuristic technique conceptualized by Stanford scientists could enable astronomical imaging far more advanced than any present today.

Earth-based telescopes that look that far back to the big bang (BB) 13.8 billion years ago are unable to resolve the relevant details.

The more humanity tries to do more with data, the more it’s evident that the most urgent questions won’t get answered easily.

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.

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.

Researchers have confirmed that a possible microlensing event witnessed in 2011 was due to the presence of a rogue black hole.

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.

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

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