Evolution Of Cosmic Carbon
2013-05-15 10:50:47

John P. Millis, PhD for redOrbit.com — Your Universe Online In addition to being a key component of life on Earth, carbon is the sixth most abundant element in the Universe. Yet despite its ubiquitous existence in the cosmos, the evolution of carbon in molecules has been difficult to study. Until now. Researchers at NASA´s Ames Research Center have taken archival data to chart how chemicals known as complex polycyclic aromatic hydrocarbons (PAHs) vary in different...

Orion Reveals A Hidden Fiery Ribbon
2013-05-15 05:10:13

[ Video 1 ] | [ Video 2 ] Lee Rannals for redOrbit.com - Your Universe Online The European Southern Observatory (ESO) has released a new image of the constellation of Orion showing part of the Orion Molecular Cloud. The image shows off clouds of gas and interstellar dust at wavelengths too long for the human eye to see. These tiny dust grains block the view of what lies within and behind the clouds, making it difficult to observe star formation taking place in this region. In...

WATCH VIDEOS: [Panning Across NGC 6559] | [Zooming In On NGC 6559] John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The Danish 1.54-metre telescope located at ESO´s La Silla Observatory in Chile has released a new image of the star-forming region NGC 6559. Located relatively nearby, a mere 5000 light-years from Earth, NGC 6559 is found in the constellation of Sagittarius (The Archer). The nebula is only a few light years across, a stark contrast to its more...

Hubble Celebrates 23 Years In Space With Spectacular View Of Horsehead Nebula
2013-04-19 13:59:48

VIDEO: [Zooming Into The Horsehead Nebula] | VIDEO: [The Gaseous Landscape Of The Horsehead Nebula] Lee Rannals for redOrbit.com — Your Universe Online The Hubble Space Telescope is celebrating its 23rd year in orbit, and to commemorate the veteran observatory, NASA and the European Space Agency (ESA) have released an amazing image of the Horsehead Nebula. For 23 years, the Hubble Space Telescope has been making cutting-edge observations of several of the sky's best objects....

Planetary nebula IC 1295
2013-04-10 05:29:10

[ 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...

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...
