The Wonder of Avi Loeb

The physicist thinks we might have glimpsed evidence of an alien civilization. Despite controversy, he’s determined to find more

DESI will analyze light collected by the four-meter Mayall telescope at Kitt Peak National Observatory near Tucson, Arizona.

New Project Aims to Create Most Detailed 3-D Map of the Universe

An instrument named “DESI” will chart up to 40 million galaxies, ten times more than any previous survey

After about a month of darkness, Hubble is back online and already collection impressive scientific data.

Retired NASA Engineers Return to Fix Hubble Telescope

The repaired space computer is back online and already beaming spectacular images of distant galaxies back to Earth

Jupiter and its largest moon Ganymede are shown in this image. Ganymede is slightly larger than the planet Mercury. Meanwhile, Jupiter's new 80th moon is much smaller, likely only a few dozen miles in diameter.

Incredibly Dense White Dwarf Star Packs the Mass of the Sun Into the Size of the Moon

Researchers say if the star was any more massive it would likely collapse under its own weight and explode

Data collected revealed that a neutron star twice as massive as the sun was swallowed up by a black hole nine times the size of the sun.

Astrophysicists Detect a Black Hole Gobbling Up a Neutron Star in Two Separate Events

Researchers spotted both events using sensors to locate ripples in spacetime that traveled 900 million years to reach Earth

An artist's rendering of the Earth and sun seen from space. Astronomers on Earth can detect other worlds when far away stars flicker as an orbiting planet passes in front of them, partly blocking our view. New research asks how many alien worlds might have been able to detect Earth in this way.

If Aliens Exist in These 1,700 Solar Systems, They Can Probably See Earth

Hypothetical alien astronomers orbiting these stars could have seen the sun’s light flicker as Earth passed in front of it

It’s considered one of the coldest and smallest exoplanets discovered so far.

This Neptune-Like Exoplanet May Have Water Clouds

Despite the possible presence of water vapor, TOI-1231 b is likely not habitable because of its size

A new image of the black hole at the center of the M87 galaxy. The image shows patterns of polarized light around the supermassive black hole, which in turn reveals the structure of the black hole’s magnetic fields.
