Despite their striking appearance, Einstein Crosses aren't evidence of distant alien megastructures. However, they could help solve the lingering mystery of dark energy.
For the first time, scientists have mapped the dark matter around distant galaxies in a cosmological analysis that studies high redshift galaxies, according to new research.
Interstellar travel would require major investments. Instead, first we should examine the objects that arrive in our solar system from interstellar space.
Astronomers have long reported sightings of mysterious flashes of light from within the Aristarchus crater, and new data could help scientists understand their source.
Asteroids provide an extremely important resource for astronomers, which includes the way they help to unravel clues about planetary origins. During past impact events, these space rocks have also helped shape the surfaces of the Earth and Moon, and have...
The first complete set of images captured by NASA’s James Webb Space Telescope, “the world’s largest and most powerful space telescope,” was just revealed by NASA.
Evidence of non-terrestrial objects of intelligent origin could turn up in a place many wouldn't expect: images of the sky that predate the dawn of the Space Race.
Astronomers have spotted a transient object they say is unique—and potentially a lot more energetic—than past examples they have witnessed, according to new research.
Gravity remains one of the great mysteries of modern physics, and this Toronto-based researcher thinks a new theoretical model may finally help to resolve it.
NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) is equipped for scanning the South American skies with a reflecting telescope mounted aboard a Boeing 747SP.
An encounter with an ET culture would be a humbling experience, since we will have to admit that our modern science was developed only over the past century out of the 4.5-billion-years-long history of Earth.
