While most solar cells on the market today are based on silicon, energy engineers have recently been assessing the ...

Oh, we humans do love a cleanly defined boundary, don’t we? They make things easier, after all. If we’re trying to categorize something, knowing what labeled bin to put it in is handy. If we’re ...

Our solar system is a smashing success. A new study suggests that from its earliest period—even before the last of its nebular gas had been consumed—Earth's solar system and its planets looked more ...

While many dream of bases on Mars and cities above Venus, the reality of colonizing the Solar System is far more difficult and may be impossible with today’s technology. NATO scrambles fighter jets as ...

A comet traveling outside the solar system and heading toward the Earth is much larger than scientists first believed, a scientist has detailed in a new report. Avi Loeb claims the comet could even be ...

The National Aeronautics and Space Administration has confirmed an interstellar object is passing through our solar system. The object is a comet hailing from the direction of the constellation ...

This illustration shows the creation of an asteroid family. Ejected fragments from catastrophic collisions of asteroids between Mars and Jupiter tend to follow similar orbits around the sun, allowing ...

The interstellar object hurtling toward the inner solar system, where Earth is located, is much larger than previously thought, astronomers say. A comet named 3I/ATLAS likely weighs more than 33 ...

A mysterious object hurtling through space has been identified as a rare “interstellar object,” only the third of its kind ever seen. In July, NASA reported its ATLAS (Asteroid Terrestrial-impact Last ...

A NASA mission, IMAP, and two more spacecraft that will study space weather are traveling through space atop a single SpaceX rocket. By Kenneth Chang A SpaceX rocket launched on Wednesday morning ...

A NASA mission to study the heliosphere—the sun's magnetic bubble that shields our solar system—and develop a better understanding of space weather was launched from the agency's Kennedy Space Center ...
