Astronomers using NASA's Hubble Space Telescope have uncovered surprising new clues about a hefty, rapidly aging star whose behavior has never been seen before in our Milky Way galaxy. In fact, the star is so weird that astronomers have nicknamed it "Nasty 1," a play on its catalog name of NaSt1. The star may represent a brief transitory stage in the evolution of extremely massive stars.

Most luminous galaxy in universe discovered
more »
A remote galaxy shining brightly with infrared light equal to more than 300 trillion suns has been discovered using data from NASA's Wide-field Infrared Survey Explorer, or WISE. The galaxy, which belongs to a new class of objects recently discovered by WISE -- nicknamed extremely luminous infrared galaxies, or ELIRGs -- is the most luminous galaxy found to date.

One-of-a-kind star discovered, nicknamed 'Nasty'
more »
Astronomers have spent decades trying to determine the oddball behavior of an aging star nicknamed "Nasty 1" residing in our Milky Way galaxy. Looking at the star using NASA's Hubble Space Telescope, astronomers had expected to see a bipolar outflow of twin lobes of gas from the star. The astronomers were surprised, however, to find a pancake-shaped disk of gas encircling the star. The vast disk is nearly 1,000 times the diameter of our solar system.

Hubble Observes One-of-a-Kind Star Nicknamed 'Nasty'

Astronomers have spent decades trying to determine the oddball behavior of an aging star nicknamed "Nasty 1" residing in our Milky Way galaxy. Nasty 1 was identified as a Wolf-Rayet star, a rapidly evolving star that is much more massive than our sun. The star loses its hydrogen-filled outer layers quickly, exposing its super-hot and extremely bright helium-burning core.

Carina Nebula - Breathtaking Universe Square Sticker
Here's a great sheet of stickers featuring a beautiful image from deep space
tagged with: stlrnrsry, star clusters, galaxies, awesome astronomy pictures, constellation puppis, the stern, star nurseries, nebulae, outer space exploration, universe photographs, starfields, european southern observatory, eso, vista
The image, looking like a colourful cosmic ghost or a gigantic celestial Mandrill, contains the open clusters Haffner 18 (centre) and Haffner 19 (middle right: it is located inside the smaller pink region - the lower eye of the Mandrill), as well as vast areas of ionised gas.
The bright star at the centre of the largest pink region on the bottom of the image is HD 64315, a massive young star that is helping shaping the structure of the whole nebular region.

A gorgeous set of oval stickers showing the area surrounding the stellar cluster NGC 2467, located in the southern constellation of Puppis ("The Stern"). With an age of a few million years at most, it is a very active stellar nursery, where new stars are born continuously from large clouds of dust and gas.The image, looking like a colourful cosmic ghost or a gigantic celestial Mandrill, contains the open clusters Haffner 18 (centre) and Haffner 19 (middle right: it is located inside the smaller pink region - the lower eye of the Mandrill), as well as vast areas of ionised gas.

New device may make converting waste heat to electricity industrially competitive
more »
(Phys.org)—Currently, up to 75% of the energy generated by a car's engine is lost as waste heat. In theory, some of this waste heat can be converted into electricity using thermoelectric devices, although so far the efficiency of these devices has been too low to enable widespread commercialization.

NGC 6240: Merging Galaxies
more »
NGC 6240 offers a rare, nearby glimpse of a cosmic catastrophe in its final throes. The titanic galaxy-galaxy collision takes place a mere 400 million light-years away in the constellation Ophiuchus. The merging galaxies spew distorted tidal tails of stars, gas, and dust and undergo fast and furious bursts of star formation. The two supermassive black holes in the original galactic cores will also coalesce into a single, even more massive black hole and soon, only one large galaxy will remain. This dramatic image of the scene is a composite of narrowband and near-infrared to visible broadband data from Hubble's ACS and WPC3 cameras, a view that spans over 300,000 light-years at the estimated distance of NGC 6240.

Helix Nebula, Beautiful Stars in the Galaxy Room Graphic
Here's a great wall decal featuring a beautiful image from deep space
tagged with: astronomy, celestial bodies, crab nebula, space, galaxy, twinkle, planets, stars, science, geek, physics, cosmos, big bang theory, hubble, telescope, exploration, orion nebula, hubble telescope, spitzer telescope, messier object, milky way, natural science, natural sciences, natural world, nebula, nobody, outer space, physical science, sciences, space exploration and research, taurus, zodiac, ngc 3603, emission nebula, universe, constellation, night sky, hubb
This infrared image from NASA's Spitzer Space Telescope shows the Helix Nebula, a cosmic starlet often photographed by amateur astronomers for its vivid colors and eerie resemblance to a giant eye. The nebula, located about 700 light-years away in the constellation Aquarius, belongs to a class of objects called planetary nebulae. Discovered in the 18th century, these colorful beauties were named for their resemblance to gas-giant planets like Jupiter. Planetary nebulae are the remains of stars that once looked a lot like our sun. When sun-like stars die, they puff out their outer gaseous layers. These layers are heated by the hot core of the dead star, called a white dwarf, and shine with infrared and visible colors. Our own sun will blossom into a planetary nebula when it dies in about five billion years. In Spitzer's infrared view of the Helix nebula, the eye looks more like that of a green monster's. Infrared light from the outer gaseous layers is represented in blues and greens. The white dwarf is visible as a tiny white dot in the center of the picture. The red color in the middle of the eye denotes the final layers of gas blown out when the star died. The brighter red circle in the very center is the glow of a dusty disk circling the white dwarf (the disk itself is too small to be resolved). This dust, discovered by Spitzer's infrared heat-seeking vision, was most likely kicked up by comets that survived the death of their star. Before the star died, its comets and possibly planets would have orbited the star in an orderly fashion. But when the star blew off its outer layers, the icy bodies and outer planets would have been tossed about and into each other, resulting in an ongoing cosmic dust storm. Any inner planets in the system would have burned up or been swallowed as their dying star expanded. So far, the Helix nebula is one of only a few dead-star systems in which evidence for comet survivors has been found. You can personalize the design further if you'd prefer, such as by adding your name or other text, or adjusting the image - just click 'Customize' to see all the options.

Trifid Nebula, Messier 16 Square Sticker
Here's a great sheet of stickers featuring a beautiful image from deep space
tagged with: breathtaking astronomy images, star forming nebulae, trfdnbl, star nurseries, galaxies, nebulae, star factory, trifid nebula, european southern observatory, clusters of stars, factories for stars, eso, vista
Galaxies, Stars and Nebulae series A fantastic picture from our universe featuring the massive star factory known as the Trifid Nebula.
It was captured in all its glory with the Wide-Field Imager camera attached to the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in northern Chile.
So named for the dark dust bands that trisect its glowing heart, the Trifid Nebula is a rare combination of three nebulae types that reveal the fury of freshly formed stars and point to more star birth in the future. The field of view of the image is approximately 13 x 17 arcminutes.
It's an awe-inspiring, breathtaking image that reveals some of the wonder that is our universe.
