NASA astronaut Don Pettit has snapped a striking shot of the super-bright comet racing past our planet for the first time in ...

New photos of comet C/2024 G3 (ATLAS) suggest that it could be disintegrating due to "thermal stress" from its recent ...

Michigan State University and NASA researchers discover seven dark comets that reveal new solar system secrets.

From Jan. 11 to 15, 2025, a bright comet surged through images from the ESA (European Space Agency) and NASA SOHO (Solar and Heliospheric Observatory) spacecraft. Called C/2024 G3 (ATLAS), the comet ...

A photo taken from the International Space Station captures the brilliant comet known as C/2024 G3 ATLAS, which could be the ...

The so-called 'planetesimal belts' are filled with tiny millimeter-sized particles created by collisions between comets.

Often, star-grazing comets such as C/2024 G3 do not survive the encounter with the Sun, though astronomers believe that this one did so in the past. This comet's period is 135,000 years – long for a ...

Because the period of an object does not depend on its mass, comets’ orbital periods remain unchanged due to mass loss.

The Large Angle and Spectrometric Coronagraph aboard the Soho spacecraft captured the view of the comet as it flew with a ...

An incredibly rare sight can be seen in the Australian skies until Thursday - and won't reappear for another 800,000 years.

Just like Earth, comets also spin on an axis (or sometimes tumble on multiple axes, like a wobbly, spinning top, but that’s a topic for another day!) as they orbit the Sun. The time it takes to ...

Some space conspiracy theories just won't go away.
