Carina Nebula in Argo Navis constellation Rectangular Sticker
Here's a great sheet of stickers featuring a beautiful image from deep space
tagged with: stars, galaxies, astronomy, peel off, carina nebula, argos navis constellation, carina the keel, star formation, gas clouds, carnebngcttst, ngc 3372
Galaxies, Stars and Nebulae series Hubble's view of the Carina Nebula shows star birth in a new level of detail. The fantasy-like landscape of the nebula is sculpted by the action of outflowing winds and scorching ultraviolet radiation from the monster stars that inhabit this inferno. In the process, these stars are shredding the surrounding material that is the last vestige of the giant cloud from which the stars were born. The immense nebula is an estimated 7,500 light-years away in the southern constellation Carina the Keel (of the old southern constellation Argo Navis, the ship of Jason and the Argonauts, from Greek mythology).
The original image is a mosaic of the Carina Nebula assembled from 48 frames taken with Hubble Space Telescope's Advanced Camera for Surveys. The Hubble images were taken in the light of ionized hydrogen. Colour information was added with data taken at the Cerro Tololo Inter-American Observatory in Chile. Red corresponds to sulfur, green to hydrogen, and blue to oxygen emission.

Green Flash at Moonrise
more »
Follow a sunset on a clear day against a distant horizon and you might glimpse a green flash just as the Sun disappears, the sunlight briefly refracted over a long sight-line through atmospheric layers. You can spot a green flash at sunrise too. Pinpointing the exact place and time to see the rising Sun peeking above the horizon is a little more difficult though, and it can be harder still to catch a green flash from the fainter rising Moon. But well-planned snapshots did record a green flash at the Full Moon's upper edge on June 2nd, from the Roque de los Muchachos Observatory on the Canary Island of La Palma. Looking a little south of due east, this long telephoto view finds the rising Moon above mountains and a sea of clouds. In sunlit profile are the mountaintop Teide Observatory telescope domes on the island of Tenerife some 143 kilometers away.

Keeping astronauts in space longer with better air and water
more »
As astronauts embark on increasingly ambitious space missions, scientists have to figure out how to keep them healthy for longer periods far from Earth. That entails assuring the air they breathe and the water they drink are safe -- not an easy task given their isolated locations. But scientists are now reporting a new method to monitor the quality of both in real time with one system.
