Astronomers found a strange planetary system 116 light-years away. It orbits a red dwarf star called LHS 1903. The planets are arranged in an unexpected order. The outermost planet is rocky, which ...

For decades, scientists have believed that planetary systems typically form with rocky planets close to their star and gas-rich planets farther away. This discovery questions their knowledge.

NASA researchers show that artificial intelligence can anticipate solar flare buildups by tracking subtle changes across the Sun’s surface.

Using data collected by NASA's Parker Solar Probe during its closest approach to the sun, a University of Arizona-led ...

Researchers in Taiwan demonstrate that installing solar panels above clam ponds can simultaneously support aquaculture and renewable energy under increasing climate stress. Using real-world farm data, ...

Things are much bigger outside the solar system.

A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit — but it may be colder than Mars due to its dimmer star. If it has a thick enough atmosphere, though, ...

Why is it so rare to find exoplanets orbiting two stars, also called circumbinary planets (CBPs)? This is what a recent study ...

Close to the sun, the solar wind, a steady stream of charged particles, accelerates until it cannot turn back. During a record pass about 3.8 million miles above the surface, Parker Solar Probe ...

The growth and impact of artificial intelligence are limited by the power and energy that it takes to train machine learning ...

Luna 9 was the first spacecraft to soft-land on the Moon, sending the first images from the lunar surface to Earth. The Luna ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...
