Out of an estimated 100 billion stars in our galaxy, no more than 14 may be made from antimatter. That's the result from a new study that scoured the Milky Way for signs of antistars — which are ...

Scientists are exploring the possibilities of antimatter propulsion as they try to achieve interstellar travel. While conventional rockets provide high thrust, they struggle with low efficiency.

Chemical rockets have taken us to the moon and back, but traveling to the stars demands something more powerful. Space X's ...

Scientists at NASA’s Chandra X-ray Observatory recently uncovered a twinkling little star that might hold the key to several of the universe’s deepest mysteries. Called a pulsar for its twinkle, the ...

Some of the greatest mysteries in cosmology revolve around antimatter, and it’s hard to study because it’s rare and hard to produce in the lab. Now a team of physicists has outlined a relatively ...

There could be several stars made of antimatter in our solar system’s neighbourhood. There have been small hints that these strange and unlikely objects, called antistars, could exist, and a search ...

As beautiful as the universe is, astronomers still can't explain why it is the way it is. The universe should be uniform, without galaxies like seen here. A physics paper released in November 2020 ...
