A letter by SETI Institute scientist Oliver White focuses one of the most enigmatic landforms yet seen on Pluto.

It was five years ago this month that ESA’s GOCE gravity-mapping satellite finally gave way to gravity, but its results are still yielding buried treasure – giving a new view of the remnants of lost continents hidden deep under the ice sheet of Antarctica.

The sun, like all stars, was born in a giant cold cloud of molecular gas and dust. It may have had dozens or even hundreds of stellar siblings – a star cluster – but these early companions are now scattered throughout our Milky Way galaxy.

Ralph, one of NASA’s most well-traveled space explorers, has voyaged far and accomplished much.

How predictable is evolution? The answer has long been debated by biologists grappling with the extent to which history affects the repeatability of evolution. A review published in the Nov. 9 issue of Science explores the complexity of evolution’s predictability in extraordinary detail. In it,

International team of scientists observe plumes of cold molecular gas sprayed out by a black hole a billion light-years from Earth.

Earth’s water may have originated from both asteroidal material and gas left over from the formation of the Sun, according to new research.

Existing laser technology could be fashioned into Earth’s “porch light” to attract alien astronomers, study finds.
