The first image of a new gaseous component in a planetary nebula

Stars end their lives, mainly, in two ways: as supernovae and planetary nebulae. In both cases they throw out into the interstellar medium the chemical elements synthesized in their interiors. Knowing the composition of this gas gives us vital information for understanding the chemical evolution of our Galaxy and the universe.

Germs add ripples to make 'groovy' graphene

more »
Graphene, a two-dimensional wonder-material composed of a single layer of carbon atoms linked in a hexagonal chicken-wire pattern, has attracted intense interest for its phenomenal ability to conduct electricity. Now researchers have used rod-shaped bacteria -- precisely aligned in an electric field, then vacuum-shrunk under a graphene sheet -- to introduce nanoscale ripples in the material, causing it to conduct electrons differently in perpendicular directions.

NASA camera catches moon 'photobombing' Earth

more »
For only the second time in a year, a NASA camera aboard the DSCOVR satellite captured a view of the moon as it moved in front of the sunlit side of Earth. From its position between the sun and Earth, DSCOVR conducts its primary mission of real-time solar wind monitoring for the National Oceanic and Atmospheric Administration (NOAA).

Astronomers discover new distant dwarf planet beyond Neptune

more »
Astronomers have discovered a new dwarf planet orbiting in the disk of small icy worlds beyond Neptune. The new object is about 700 km in diameter and has one of the largest orbits for a dwarf planet. Designated 2015 RR245 by the International Astronomical Union's Minor Planet Center, it was found using the Canada-France-Hawaii Telescope on Maunakea, Hawaii, as part of the ongoing Outer Solar System Origins Survey (OSSOS).
