Scientists now say an interstellar comet discovered earlier this month could be one of the oldest that astronomers have ever encountered.

How did Earth, alone among the Solar System's rocky planets, become the home for life? How, among all this frigid lifelessness, did our planet become warm, hospitable, and life-sustaining? The answer to these questions is complex and multi-faceted,

Occasionally, asteroids get caught in Earth’s orbit, temporarily becoming mini moons before continuing their cosmic paths. These rare occurrences offer

How did Earth, alone among the solar system's rocky planets, become the home for life? How, among all this frigid lifelessness, did our planet become warm, hospitable, and life-sustaining? The answer to these questions is complex and multi-faceted,

But in space or on the Moon, there are no power lines, no sunlight at night and no backup grid. Every system — from life support and communication to heat, lights and research tools — runs on power. For astronauts,

The mission aims to collect samples from the near-Earth asteroid 2016 HO3 and explore the main-belt comet 311P.

Recreating artificial solar eclipses in space could help astronomers decipher the inner workings of our sun much quicker than if they had to wait for the celestial show on Earth.

The burst was so bright that it bounced off the Moon and illuminated Earth’s upper atmosphere, surpassing the brightness of a full moon for a fraction of a second.

Astronomers are meticulously tracking the new interstellar visitor that is crossing our solar system. Officially designated as 3I/ATLAS, this object is a comet that originated outside our solar system will soon make its closest approach to the Sun.
