[ Watch the Video: Zooming In On The Planetary Nebula IC 1295 ] Lee Rannals for redOrbit.com - Your Universe Online A new image released by the European Space Observatory (ESO) shows the glowing green planetary nebula IC 1295. The new pictures taken by the Very Large Telescope (VLT) shows the nebula surrounding a dim and dying star located about 3300 light-years away in the constellation of Scutum (The Shield). "It has the unusual feature of being surrounded by multiple shells...

X-Ray Emissions In Young Metal-Poor Stars Similar To Metal-Rich Stars
2013-04-03 08:10:18

Lawrence LeBlond for redOrbit.com - Your Universe Online Astronomers have found that a region of space known as the Wing has fewer “metals” (elements with more than two protons in the nucleus) compared to most other areas within our own Milky Way galaxy. There are also relatively lower amounts of gas, dust and stars in the Wing compared to the Milky Way. This knowledge makes the Wing an excellent candidate for the study of the life cycle of stars and the gas lying between...

Nebula Launches Cloud Based Computer
2013-04-02 11:29:29

Michael Harper for redOrbit.com — Your Universe Online It´s been a long time coming, but Nebula One, the cloud based computer that harnesses the power of multiple computers into one package, has finally been launched. This setup allows computers manufactured by Dell, HP and IBM to be plugged into one system and controlled by a single person via Nebula´s control software. The Nebula One also works well with other cloud-based solutions, such as OpenStack or Amazon Web...

Astronomers Spot 'Soccer Ball' Molecules In Space
2013-03-05 13:10:23

Lee Rannals for redOrbit.com - Your Universe Online An international team of astronomers are reporting in The Astrophysical Journal they have spotted what resembles a soccer ball sitting in the dying star M1-11. Five instruments helped astronomers detect C60 fluorine in the dying star, which are molecules of carbon with 60 atoms arranged in patterns that resemble a soccer ball. Astronomers used the Subaru Telescope, the Spitzer Space Telescope (SST), ESO's Very Large Telescope, the...

Astronomers Shed Light On Old Star Using New Greek Observatory
2013-02-27 08:44:17

The Royal Astronomical Society Continuing a tradition stretching back more than 25 centuries, astronomers have used the new 2.3-m 'Aristarchos' telescope, sited at Helmos Observatory (2340m high) in the Pelοponnese Mountains in Greece, to determine the distance to and history of an enigmatic stellar system, discovering it to likely be a binary star cocooned within an exotic nebula. The researchers, Panos Boumis of the National Observatory of Athens and John Meaburn of the...

Cosmic Gecko Imaged By ESO's Wide Field Imager
2013-02-13 05:09:02

[ Video 1 ] | [ Video 2 ] | [ Video 3 ] Lee Rannals for redOrbit.com - Your Universe Online A new image released by the European Space Observatory (ESO) illustrates the bright star cluster NGC 6520, located in one of the richest star fields in the sky. Astronomers using ESO's La Silla Observatory in Chile took advantage of the Wide Field Imager on the telescope to snap the image. The image not only shows off NGC 6520, but also its neighbor, the strange dark cloud known as Barnard...

WISE Captures The Heat From Orion's Sword
2013-02-06 09:58:22

NASA's Jet Propulsion Laboratory The tangle of clouds and stars that lie in Orion's sword is showcased in a new, expansive view from NASA's Wide-field Infrared Survey Explorer, or WISE. Orion, the famous hunter, is visible in evening skies throughout the world from about December through April. The constellation appears tranquil and still to the naked eye, but lying in its sword, at what appears to be a slightly fuzzy star, is a turbulent cauldron of stellar birth. WISE scanned the...

Seagull Nebula Wings Shown In New ESO Image
2013-02-06 05:10:24

[ Video 1 ] | [ Video 2 ] Lee Rannals for redOrbit.com - Your Universe Online A new image released by the European Space Observatory (ESO) taken by its Wide Field Imager shows off a section of the Seagull Nebula. The cloud of dust and glowing gas seen in the image that forms the "wings" of the seagull reveals a mix of dark and glowing red clouds. The Seagull Nebula, or IC 2177, lies between the constellations of Canis Major and Monoceros in the southern sky. Astronomers refer to...

Manatee Nebula Named For Its Resemblance To The Sea Cow
2013-01-19 07:04:37

[ Watch the Video: A Microquasar Makes a Giant Manatee Nebula ] redOrbit Staff & Wire Reports - Your Universe Online Thanks to a powerful National Science Foundation (NSF) telescope and an observation made by one National Radio Astronomy Observatory (NRAO) official, the W50 nebula located approximately 18,000 light years away has a new name — the Manatee Nebula. Images of the massive supernova remnant captured recently by the NSF´s Karl G. Jansky Very Large Array (VLA)...

Hubble Image Of Planetary Nebula Resembles Christmas Ribbon
2012-12-18 13:37:12

Lee Rannals for redOrbit.com — Your Universe Online NASA and the European Space Agency (ESA) have released a new Hubble Space Telescope image of the planetary nebula NGC 5189. In the essence of the Christmas spirit, ESA describes the cosmic structure of the eruption as a "giant and brightly colored ribbon in space." The structure visible within NGC 5189 is particularly dramatic, and the space agencies said the image is the most detailed yet image of this object. Planetary...

Supernova Remnant -- A supernova remnant (SNR) is made up of the materials left behind by the gigantic explosion of a star in a supernova. There are two possible routes to this end: either a massive star may cease to generate fusion energy in its core, and collapse inward under the force of its own gravity, or a white dwarf star may accumulate material from a companion star until it reaches a critical mass and undergoes a similar collapse. In either case, the resulting supernova...

Star -- A star is a self-gravitating sphere of plasma in hydrostatic equilibrium that generates energy in its interior through the process of nuclear fusion. Energy from this process radiates into space as electromagnetic radiation and neutrinos. Star formation and evolution As learned by star formation astronomers, stars are born in molecular clouds, regions of higher density of matter, and form by gravitational instability inside those clouds. High mass stars illuminate powerfully...

Reflection Nebula -- In astronomy, reflection nebulae are clouds of dust which are simply reflecting the light of a nearby star or stars. The nearby star or stars are not hot enough to cause ionization in the gas of the nebula like in emission nebulae but are bright enough to give sufficient scattering to make the dust visible. The distiction between these two types of nebulae was done by Hubble in 1922. They are usually blue because the scattering is more efficient for blue light...

Planetary Nebula -- A planetary nebula is an astronomical object that usually appears nebulous and disk-like in low-resolution observations. Because of this appearance, similar to the appearance of planets in early observations, the "planetary" adjective was attached and has since been retained for historical consistency. According to current observations and models, planetary nebulae in fact have little to do with planets. Instead, as a small star (less than a few times the mass...

Nebula -- in astronomy, observed manifestation of a collection of highly rarefied gas and dust in interstellar space. Prior to the 1960s this term was also applied to bodies later discovered to be galaxies, e.g., the so-called Great Nebula in the constellation Andromeda. In 1864, William Huggins confirmed William Herschel's conclusion that nebulae are not swarms of stars by determining that the spectra of nebulae are made of bright lines characteristic of radiating gases. Diffuse...
