Now, in a study published Wednesday, the odd orbit of 'Oumuamua can be explained by a simple physical mechanism that's probably common among many icy comets: outgassing of hydrogen as the comet ...

But ‘Oumuamua was much smaller than your typical comet, at just over 100 meters across, and when it was first observed, it didn’t have a tail and didn’t seem to be ejecting water.

You have just a few weeks left to view the "comet of the century" making its 80,000-year orbit around Earth. Comet C/2023 A3 Tsuchinshan–ATLAS will be visible with the naked eye from Earth until ...

The comet's approach toward Earth coincides with a total solar eclipse on April 8. Around that time, 12P/Pons-Brooks will be at or near perihelion, the point during orbit when it's closest to the sun.

Astronomers discovered a new comet just in time for its closest approach to Earth in early 2023, however, after this encounter, comet C/2022 E3 won’t be coming by Earth for a very long time. … ...
