Astronomers Have Discovered 2 Super-Earths Orbiting a Nearby Star

Two new worlds of probable rocky mineral goodness have just been found orbiting a star close to our own cosmic neighborhood. The two newly discovered exoplanets are what are known as super-Earths – bigger than Earth, but smaller than an ice giant – orbiting a cool red dwarf star called HD 260655, which is just …

NASA prepares to power-down Voyager spacecraft after more than 44 years | Science&TechNews

After more than 44 years of traveling farther from Earth than any man-made objects have before, the Voyager spacecraft are entering their very final phase. Both of the Voyagers were launched from Cape Canaveral in 1977 – with Voyager 2 actually the first to take off – taking advantage of a rare alignment (once every …

Martian meteorite upsets planet formation theory

Credit: Pixabay/CC0 Public Domain A new study of an old meteorite contradicts current thinking about how rocky planets like the Earth and Mars acquire volatile elements such as hydrogen, carbon, oxygen, nitrogen and noble gases as they form. The work is published June 16 in Science. A basic assumption about planet formation is that planets …
