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...

New Image Shows Off Star Birth Region In Orion
2013-01-23 05:14:35

Lee Rannals for redOrbit.com - Your Universe Online A new image released by the European Space Observatory (ESO) shows off a great view of clouds of cosmic dust in Orion. ESO's Atacama Pathfinder Experiment (APEX) telescope in Chile helps bring out the heat glow of the dust, revealing places where new stars are being formed. Dense clouds of cosmic gas and dust in space are the birthplaces of new stars. When viewing these in visible light, the dust is dark and obscuring, which helps...

Hubble Space Telescope Snaps Image Of Large Magellanic Cloud’s Hidden Treasure
2013-01-17 07:37:54

[Watch Video 1] [Watch Video 2] Lawrence LeBlond for redOrbit.com - Your Universe Online The Large Magellanic Cloud (LMC), an irregular galaxy that shares some features with spiral galaxies, is known for its array of star-forming regions. One of those regions, LHA 120-N 11 (N11), captured by the Hubble Space Telescope, offers proof that the LMC is producing noticeable signs that stellar nurseries within are still hard at work. The LMC is in an ideal position for astronomers to study...

Astronomers Capture Rare Glimpse Of Star-Forming Region In Visible Light
2013-01-16 07:00:46

[Watch Videos: 1 - Zooming in on Lupus 3 / 2 - Panning Over Lupus 3] Lawrence LeBlond for redOrbit.com - Your Universe Online The European Southern Observatory (ESO) released a stunning new image of a dark cloud where new stars are forming, along with a cluster of brilliant stars that have already emerged from the stellar nursery. The new image, taken with MPG/ESO 2.2-meter telescope at La Silla Observatory in Chile, is one of the finest and clearest ever taken in visible light of...

Dense Cloud Defies Rules Of Star Formation
2013-01-13 09:53:05

redOrbit Staff & Wire Reports — Your Universe Online An unusually dense cloud located near the center of the galaxy does not appear to be forming any massive stars, astronomers at the California Institute of Technology (Caltech) have discovered, and that behavior has them puzzled as it appears to defy the rules of star formation. The cloud, which the researchers have named G0.253+0.016, is located in the vicinity of a supermassive black hole three millions times as massive as...

Starbursts Caught Near The Milky Way's Galactic Center
2013-01-09 10:47:01

redOrbit Staff & Wire Reports - Your Universe Online Using the airborne telescope on the Stratospheric Observatory for Infrared Astronomy (SOFIA), astronomers have learned that a series of recent starbursts had taken place in the central region of the Milky Way, NASA officials reported on Tuesday. According to the US space agency, our galaxy´s nucleus is home to a black hole with four million times the mass of the sun. It is orbited by a large disk of dust and gas, and holds...

With its 2160 liters of liquid helium about to run out, the Herschel Space Observatory will, by the end of March, become just another piece of space junk. In January´s Physics World, Steve Eales, a University of Cardiff astronomer who leads one of the telescope´s largest surveys, explains how this space facility has advanced our understanding of star and galaxy formation. Submillimeter wavelength astronomy -- the kind of astronomy that the European Space Agency´s Herschel...

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...

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
