Stellar discovery: Researcher discovers massive binary star with unique properties

more »
The first massive binary star, epsilon Lupi, in which both stars have magnetic fields has been discovered by a PhD candidate. A binary star is a star system consisting of two or more stars, orbiting around their common center of mass.

Globally unique double crater identified in Sweden

more »
Researchers have found traces of two major meteorite impacts in Sweden, a twin strike that occurred around 460 million years ago. One is enormous, while the other is a tenth of the size of the first. The largest crater has a diameter of 7.5 kilometers.

A Giant Squid in the Flying Bat

more »
Very faint but also very large on planet Earth's sky, a giant Squid Nebula cataloged as Ou4, and Sh2-129 also known as the Flying Bat Nebula, are both caught in this scene toward the royal constellation Cepheus. Composed with a total of 20 hours of broadband and narrowband data, the telescopic field of view is almost 4 degrees or 8 Full Moons across. Discovered in 2011 by French astro-imager Nicolas Outters, the Squid Nebula's alluring bipolar shape is distinguished here by the telltale blue-green emission from doubly ionized oxygen atoms. Though apparently completely surrounded by the reddish hydrogen emission region Sh2-129, the true distance and nature of the Squid Nebula have been difficult to determine. Still, a recent investigation suggests Ou4 really does lie within Sh2-129 some 2,300 light-years away. Consistent with that scenario, Ou4 would represent a spectacular outflow driven by a triple system of hot, massive stars, cataloged as HR8119, seen near the center of the nebula. If so, the truly giant Squid Nebula would physically be nearly 50 light-years across.

Star GL 490 Green Cluster Space Room Decal

Here's a great wall decal featuring a beautiful image from deep space


tagged with: star photo, star cluster, nebula, star formation, green sky, nasa, universe, outer space, spitzer telescope, cool astronomy, astronomy, glowing, cosmos, cosmic, astronomical, astrophotography, cosmology, deep space, space, nature, natural, science, abstract, space picture, photo, image, stars, picture, light, sparkling, sparkly, starry, twinking, stellar, cool space

This is a NASA space photograph from the GLIMPSE360 survey, showing the star GL 490 (the bright orange star in the centre-right of the photo) and its surroundings. The cloudy green gaseous area is the result of hydrogen and carbon compounds that are used in the formation of new stars. This is a composite image that uses data from the Spitzer Space Telescope and the Two Micron All Sky Survey (2MASS).

Name, Cats Eye Nebula, Eye of God outer space Wrapping Paper

Get your out-of-this-world gift wrap here! Perfect for Christmas gifts for anyone who is fascinated by what the universe holds in store for us!


tagged with: nebulae, hubble chandra images, cats eye nebula, dying star, red giant evolution, outer space, galaxy stars, tcenebnch, deep space astronomy, eye of god, stellar evolution, nasa

Galaxies, Stars and Nebulae series A gorgeous design featuring a composite image of the Cat's Eye nebula from NASA's Chandra X-ray Observatory and the Hubble Space Telescope.
This famous nebula represents a phase of stellar evolution after a star like our Sun runs out of fuel. In this phase, a star becomes an expanding red giant and sheds some of its outer layers, eventually leaving behind a hot core that collapses to form a dense white dwarf star. A fast wind emanating from the hot core rams into the ejected atmosphere, pushes it outward, and creates the graceful filamentary structures.

Stellar Nursery R136 in the Tarantula Nebula Rectangular Sticker

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: galaxies, dorneblmc, stellar nursery, 30 doradus nebula, large magellanic cloud, amazing hubble images, tarantula nebula, r136, star cluster, astronomy pictures, massive stars

Galaxies, Stars and Nebulae series Hundreds of brilliant blue stars wreathed by warm, glowing clouds in appear in this the most detailed view of the largest stellar nursery in our local galactic neighborhood. The massive, young stellar grouping, called R136, is only a few million years old and resides in the 30 Doradus (or Tarantula) Nebula, a turbulent star-birth region in the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way.
There is no known star-forming region in our galaxy as large or as prolific as 30 Doradus. Many of the diamond-like icy blue stars are among the most massive stars known. Several of them are over 100 times more massive than our Sun. These hefty stars are destined to pop off, like a string of firecrackers, as supernovas in a few million years. The image, taken in ultraviolet, visible, and red light by Hubble's Wide Field Camera 3, spans about 100 light-years.
The movement of the LMC around the Milky Way may have triggered the massive cluster's formation in several ways. The gravitational tug of the Milky Way and the companion Small Magellanic Cloud may have compressed gas in the LMC. Also, the pressure resulting from the LMC plowing through the Milky Way's halo may have compressed gas in the satellite. The cluster is a rare, nearby example of the many super star clusters that formed in the distant, early universe, when star birth and galaxy interactions were more frequent.
The LMC is located 170,000 light-years away and is a member of the Local Group of Galaxies, which also includes the Milky Way. The Hubble observations were taken Oct. 20-27, 2009. The blue color is light from the hottest, most massive stars; the green from the glow of oxygen; and the red from fluorescing hydrogen.
