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

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.

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

A new image released by the European Space Observatory illustrates the bright star cluster NGC 6520, located in one of the richest star fields in the sky.

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

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.

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

A new image released by the European Space Observatory 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.

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

Thanks to a powerful National Science Foundation telescope and an observation made by one National Radio Astronomy Observatory official, the W50 nebula located approximately 18,000 light years away has a new name – the Manatee Nebula.

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

NASA and the ESA reveal a Hubble Space Telescope image of a planetary nebula that resembles a Christmas ribbon.

Orion Nebula Lives Behind Cluster Of Older Stars
2012-11-14 06:26:22

The Orion nebula is viewed, unsurprisingly, as a benchmark for star formation studies by astronomers; a true golden standard. Most of the established measurements of how stars form have been derived from observations of the Orion nebula.

Aging Stars Sculpt Spectacular Shape Of Planetary Nebula
2012-11-08 14:21:55

Astronomers have discovered a pair of stars orbiting each other at the center of a remarkable example of a planetary nebula. The latest find confirms a theory about what controls the spectacular and symmetric appearance of the material flung out into space.

Planetary Nebula Survey By Chandra
2012-10-11 05:21:48

An international team of astronomers using NASA's Chandra X-ray Observatory has created a sweeping new survey of dying stars – or planetary nebula – in the neighborhood of the Sun.

Seagull Nebula

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...
