Solar System Set For Eventual Collision With Stellar Orange Dwarf

A local orange dwarf star has a 90 percent probability of passing within the orbit of our outer solar system’s Oort Cloud between 240,000 and 470,000 years from now, says the author of a new study detailing the computer-modeled orbits of more than 50,000 nearby stars.<p>In a paper just accepted for …

NGC 7023: The Iris Nebula!

<b>NGC 7023: The Iris Nebula!</b><p>These clouds of interstellar dust and gas have blossomed 1,300 light-years away in the fertile star fields of the constellation Cepheus. Sometimes called the Iris Nebula, NGC 7023 is not the only nebula in the sky to evoke the imagery of flowers, though. Still, this deep telescopic view shows off the Iris Nebula's range of colors and symmetries in impressive detail. Within the Iris, dusty nebular material surrounds a hot, young star. The dominant color of the brighter …

The Flames of Supergiant Star Betelgeuse

<b>The Flames of Supergiant Star Betelgeuse</b><br>This picture of the dramatic nebula around the bright red supergiant star Betelgeuse was created from images taken with the VISIR infrared camera on ESO’s Very Large Telescope (VLT). This structure, resembling flames emanating from the star, forms because the behemoth is shedding its material into space. The earlier NACO observations of the plumes are reproduced in the central disc.<p>The small red circle in the middle has a diameter about four and half …

<b>NASA’s Chandra Weighs Most Massive Galaxy Cluster in Distant Universe</b> | This Chandra composite image shows the distant and massive galaxy cluster that is officially known as XDCP J0044.0-2033. Dec. 18, 2014: A newly discovered galaxy cluster is the most massive one ever detected with an age of 800 million years or younger. Using data from NASA’s Chandra X-ray Observatory, astronomers have accurately determined the mass and other properties of this cluster, as described in our latest press …

<b>The Great Andromeda Galaxy</b>
The Andromeda Galaxy, also known as Messier 31 or NGC 224, is a spiral galaxy that is approximately 2.5 million light-years away in the Andromeda constellation. The Andromeda Galaxy is the nearest spiral galaxy to our Milky Way galaxy, but not the nearest galaxy overall. The Andromeda Galaxy is also the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum Galaxy, and about 44 other smaller galaxies. Our Milky Way and the Andromeda are …

<b>Day 13</b> of the <b>2014 Hubble Space Telescope Advent Calendar</b> - http://goo.gl/g4BawQ - 25 photos eventually. The Cat's Eye Nebula. This Hubble image of the Cat's Eye Nebula shows a bull's eye pattern of eleven or even more concentric rings, or shells. Each "ring" is actually the edge of a spherical bubble seen projected onto the sky - that's why it appears bright along its outer edge. Observations suggest the star ejected its mass in a series of pulses at 1,500-year intervals. These convulsions …

Lagoon Nebula

Lagoon Nebula<br>Saturday September 6, 2014<br>The M8 Lagoon Nebula or NGC 6523, is an emission nebula in the constellation of Sagittarius. Is approximately at a distance of 5,000 light years. It was discovered by Guillaume Le Gentil in 1747. He seems to have a depth comparable to its width and includes a number of Bok globules (clouds of gas and dust) in the process of collapse to form stars, some of which have been cataloged by Edward Emerson Barnard.<p>In the brightest part of the nebula a structure …

Hoag's Object, a galaxy made up of a nearly perfect ring of hot, blue stars rotating around a yellow nucleus. The entire galaxy is about 120,000 light-years wide, which is slightly larger than our Milky Way Galaxy. What appears to be a gap separating the two stellar populations may actually contain some star clusters that are almost too faint to see. Curiously, an object that bears an uncanny …

This is just a small portion of one of the largest seen star-birth regions in the galaxy, the Carina Nebula. Towers of cool hydrogen laced with dust rise from the wall of the nebula. The scene is reminiscent of Hubble’s classic “Pillars of Creation" photo from 1995, but is even more striking in appearance. The image captures the top of a three-light-year-tall pillar of gas and dust that is being eaten away by the brilliant light from nearby bright stars. The pillar is also being pushed apart …
