Astrophysicists studying a popular exoplanet in its star's habitable zone have found that electric currents in the planet's upper atmosphere could create sufficient heating to expand the atmosphere enough that it leaves the ...
NASA and other space agencies worldwide periodically send robots and automated vehicles into space to explore planets and other celestial objects in our solar system. These missions can greatly improve our understanding of ...
Japan's Aerospace Exploration Agency sent the Hayabusa2 spacecraft to 162173 Ryugu in 2019, an asteroid in orbit near Earth that is comprised of rocky fragments originating from a larger parent body. Multiple rovers brought ...
During their entry to Earth, meteoroids and asteroids can deposit energy, causing great concerns to astrophysicists. Recent discoveries of the massive Aletai irons in Northwest China constitute the longest-known strewn field, ...
Mercury is a most unusual planet. The smallest planet in the solar system, and the closest planet to the sun, it is in a 3:2 spin resonance, slowly turning and experiencing scorching heat up to 430 degrees Celsius, and the ...
Planet Earth is surrounded by a system of magnetic fields known as the magnetosphere. This vast, comet-shaped system deflects charged particles coming from the sun, shielding our planet from harmful particle radiation and ...
On Aug. 5, 2026, an abandoned piece of space junk is predicted to crash into the moon near a spot called Einstein Crater. Astronomers will be watching because the collision and aftermath may be visible from Earth.
Researchers in the U.S. have carried out the most stringent tests to date of the idea that an ultraviolet glow in the atmospheres of giant planets could partly arise through the indirect interaction between dark matter and ...
Nearly a decade after the discovery of LHS 1140b, a rocky exoplanet in the habitable zone of a nearby low-mass star, a new study reveals that the object may have its own atmosphere.
