The origin and nature of Mars is mysterious. It has geologically distinct hemispheres, with smooth lowlands in the north and cratered, high-elevation terrain in the south. The red planet also has two small oddly-shaped oblong moons and a composition that sets it apart from that of the Earth.
Scientists have discovered mystery signals coming from a star 11 light-years away. The “very peculiar” pulses appear to be unique to the red dwarf, scientists say, with observations of similar nearby stars showing no similar behavior.
Unchecked climate change would eventually lead to widespread devastation on Earth.
NASA’s Van Allen Probes have observed a new population of space sound waves, called plasmaspheric hiss, which are important in removing high-energy particles from around Earth that can damage satellites.
Searching for aliens is a tricky business. Most likely, the first alien life we discover will be hidden beneath miles of ocean on a distant world like Jupiter’s moon Europa or Saturn’s moon Enceladus.
Scientists have long held the belief that planets — including Earth — were built from rocky asteroids, but new research challenges that view.
A new study of a nearby cluster of newly formed stars reveals that brown dwarfs may rival stars in the Milky Way in number, with one brown dwarf for every two bona fide stars.
Russia’s first crowd-funded satellite, named Mayak (Russian for “beacon of light”), promises to be the “brightest object in the night sky next to the Moon.”
Astronomers say they’ve detected “strange signals” coming from the direction of a small, dim star located about 11 light-years from Earth.
Sealed behind the steel doors of two bunkers in a Beijing suburb, university students are trying to find out how it feels to live in a space station on another planet, recycling everything from plant cuttings to urine.
