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....

Young Universe Was A Massive Factory For Star Formation
2013-04-17 13:36:09

Lee Rannals for redOrbit.com — Your Universe Online Astronomers say they have discovered a star factory in a galaxy so distant that they see it when the Universe was only six percent of its current age of about 13.7 billion years old. The team wrote in the journal Nature that HFLS3 sits at about 12.8 billion light-years from Earth. They said the distant galaxy is producing about 3,000 Suns per year, which is more than 2,000 times that of our own Milky Way galaxy. "This is the...

Airborne Observatory Reveals Mystery Of Star Formation
2013-04-17 11:52:24

Brett Smith for redOrbit.com - Your Universe Online Using observations from an airborne observatory, NASA researchers have discovered new details on how massive stars form within a cloud of interstellar gas and dust. An emerging star known as G35 has been observed forming in an orderly process similar to the one undergone by smaller stars like our sun, according to the scientists´ report in the Astrophysical Journal. Lead author Yichen Zhang said the observations of G35 made...

Unexpected Star Formation Found Near Massive Black Hole
2013-04-05 10:29:46

Brett Smith for redOrbit.com - Your Universe Online The entire Milky Way galaxy revolves around a supermassive black hole, which is surrounded by a turbulent expanse of space fraught with extreme gravitational forces. Despite the inhospitable nature of this region, a team of American astronomers has found jets of material that typically indicate star formation when found in less tumultuous sections of the universe, according to their report in the Astrophysical Journal Letters....

Older Stars Help Baby Stars Grow Up To Be Massive
2013-03-28 08:55:25

April Flowers for redOrbit.com - Your Universe Online Stars with ten times or more the mass of our Sun should not exist. They push away the gas they feed on as they grow, starving themselves for fuel. Astrophysicists have been struggling to understand how some stars are able to overcome this developmental hurdle. A group of researchers led by the University of Toronto suggests that baby stars might grow to have great mass if they are lucky enough to be born within a corral of older...

Hunting High-mass Stars With Herschel Space Observatory
2013-03-27 13:09:59

ESA In this new view of a vast star-forming cloud called W3, ESA´s Herschel space observatory tells the story of how massive stars are born. W3 is a giant molecular cloud containing an enormous stellar nursery, some 6200 light-years away in the Perseus Arm, one of our Milky Way Galaxy´s main spiral arms. Spanning almost 200 light-years, W3 is one of the largest star-formation complexes in the outer Milky Way, hosting the formation of both low- and high-mass stars. The...

Europe's Herschel Space Observatory Has Detected Some Very Young Stars
2013-03-20 10:59:56

April Flowers for redOrbit.com - Your Universe Online Some of the youngest stars ever seen have recently been found, thanks to the European Space Agency's (ESA) Herschel Space Observatory. Herschel's observations were used in conjunction with contributing observations from NASA's Spitzer Space Telescope and the Atacama Pathfinder Experiment (APEX) telescope in Chile -- a collaboration involving the Max Planck Institute for Radio Astronomy (MPIFR) in Germany, the Onsala Space Observatory...

T Tauri -- T Tauri stars are a class of stars thought to represent extremely young pre-main sequence stars, in an early stage of life. They are seen near many molecular clouds in our galaxy. The first ones were found in 1945, identified by their optical variability and strong chromospheric lines. T Tauri stars have masses and temperatures similar to the Sun, but are significantly brighter. They have fast rotation rates, typically with a period of a few days, compared to a month for...

Star Formation -- Star formation is the process by which gas in molecular clouds gets transformed into stars. In the current paradigm of star formation, cores of molecular clouds (regions of specially high density) became gravitationally unstable, and start to concentrate. Part of the gravitational energy lost in the process is radiated in the infrared, another part increases the temperature of the core. The accretion of material happen partially though a circumstellar disc. When...

Molecular Cloud -- Molecular clouds are interstellar nebulae that have a density and size sufficient to permit the formation of H2, molecular hydrogen. However, this molecule is difficult to detect, and the molecule most used to trace the H2 is CO (carbon monoxide). The ratio between CO luminosity and H2 mass is roughly constant, although there are reasons to doubt this assumption in observations of some other galaxies. In the Milky Way, molecular clouds account for roughly one-half...

H II Region -- An H II region is an emission nebula associated with hot, young, blue stars, and star forming regions. H II, or singly-ionized hydrogen, is nebular gas ionized by ultraviolet light emitted by these hot, young stars of spectral type O and B. The sizes of H II regions are determined both by the amount of gas present, and by the luminosity of the O and B stars -- the more luminous the stars are, the larger the H II region can be. H II regions are found within the spiral...

Horsehead Nebula -- The Horsehead Nebula, a part of the optical nebula IC434 and also known as Barnard 33, was first recorded in 1888 on a photographic plate taken at the Harvard College Observatory. Its coincidental appearance as the profile of a horse's head and neck has led to its becoming one of the most familiar astronomical objects. It is, in fact, an extremely dense cloud projecting in front of the ionized gas that provides the pink glow so nicely revealed in this picture. We...
