Hubble reveals the ring nebula's true shape

(Phys.org) —The Ring Nebula's distinctive shape makes it a popular illustration for astronomy books. But new observations by NASA's Hubble Space Telescope of the glowing gas shroud around an old, dying, sun-like star reveal ...

NASA-built nanosatellite launch adapter system ready for flight

(Phys.org) —Nanosatellites now have their own mass transit to catch rides to space and perform experiments in microgravity. A new NASA-designed and developed satellite deployer, dubbed the Nano Launch Adapter System (NLAS), ...

Orion's hidden fiery ribbon

(Phys.org) —This dramatic new image of cosmic clouds in the constellation of Orion reveals what seems to be a fiery ribbon in the sky. This orange glow represents faint light coming from grains of cold interstellar dust, ...
