Venus gets called Earth’s twin because of how similar the two planets are in size and structure, but that’s where […] ...

Astronomers have found a compact new cluster of objects inside the Kuiper belt, which is a distant band of icy bodies at the edge of our solar system beyond Neptune. The cluster sits 4.0 billion miles ...

Comet 3I/ATLAS will get closest to Earth on Dec. 19, and astronomers will be watching. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Darryl Z.

Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...

The system is based on a highly compact and flexible ultrathin soft solar blanket that acts as the collection panel and can unroll once the satellite reaches orbit. As it does so, a 3D printer system ...

Far beyond Neptune, at the outer rim of our Solar System, astronomers have spotted what resembles a hidden “structure” or “band” of small worlds. The Kuiper Belt is a vast ring of icy bodies beyond ...

Nothing manmade has reached further from Earth than the Voyager series of spacecraft. Hurtling away from the sun at 38,000 miles an hour, the duo have now traveled over 12 billion miles, with Voyager ...

Astronomers have spotted an intriguing cluster of objects in the Kuiper belt, the enormous, donut-shaped region of icy objects beyond the orbit of Neptune. This latest “inner kernel” was identified by ...

The Kuiper belt, a disc of icy rocks on the outermost edges of the solar system, seems to have more structure than we thought. In 2011, researchers found a cluster of objects there on similar orbits ...

A new analysis of radio galaxies hints that our solar system is racing through the universe much faster than expected, defying key predictions of standard cosmology. Credit: Shutterstock Study from ...

Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and ...

WASHINGTON — The Army is launching a complete rework of its weapons portfolio organization in the biggest acquisition shakeup the service has seen in years, officials exclusively told Breaking Defense ...
