Nebula Private Cloud Decouples Cost From Scale, Enabling Enterprises to Utilize Existing Workflows and Architecture with Private Clouds MOUNTAIN VIEW, Calif., Dec.
New upgraded benchtop nanocoating machine now fully-automated and more cost-effective with North American leasing programs through Direct Capital. LOS ANGELES, Oct.
Blue Box’s Jesse Proudman, Myles Steinhauser and Craig Tracey to lead four debates and discussions about OpenStack. SEATTLE, Wash.
The Wide Field Imager on the MPG/ESO 2.2-meter telescope at ESO’s La Silla Observatory in Chile has taken this beautiful image, dappled with blue stars, of one of the most star-rich open clusters currently known — Messier 11, also known as NGC 6705 or the Wild Duck Cluster.
Joshua McKenty, cloud computing pioneer and entrepreneur, joins Pivotal as Field CTO for Pivotal Cloud Foundry SAN FRANCISCO, Sept.
The Wide Field Imager at the ESO’s La Silla Observatory in Chile has captured new images of two dramatic regions of star formation in the southern Milky Way, one of which features a Wolf–Rayet multiple star system.
For many years astronomers have known that young 'protostars' drive supersonic jets of gas from their north and south poles. However, this is the first time that so many of them have been detected at once.
In the mid-1800s a massive eruption occurred in the binary Eta Carinae, emitting 10 times the sun’s mass and becoming the second brightest star in the sky. Astronomers have developed a high-resolution 3D model of the expanding cloud produced by the outburst.
The little-known cloud of cosmic gas and dust called Gum 15 is the birthplace and home of hot young stars. Beautiful and deadly, these stars mold the appearance of their mother nebula and, as they progress into adulthood, will eventually also be the death of her.
The region in space around a planetary nebula is filled with harsh radiation. Yet despite this hostile environment, the area is seeded with a molecule essential to the formation of water.
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...
