Astronomers used ESO's Atacama Large Millimeter/submillimeter array to gain one of the best views yet of a star in the process of forming.

Galactic Raw Material Plays Crucial Role In Star Formation
2013-06-25 08:28:48

New observations using an Australian telescope have offered up evidence of the raw material that played a part in forming some of the first stars in galaxies when the Universe was just three billion years old.

More Galactic Gas In Milky Way Than We Thought
2013-06-11 14:31:02

The building blocks of stars, molecular gases and clouds, are strewn across the Milky Way, and a new study has found that scientists have been underestimating the amount of gas in the galaxy by about one-third.

Very Large Telescope Celebrates 15 Years

The European Southern Observatory (ESO) has released a new image of the constellation of Orion showing part of the Orion Molecular Cloud.

Pinpointing Radio Wave Origins In The Distant Universe
2013-05-01 05:04:41

For the first time, astronomers have identified discrete sources that account for nearly all of the radio waves coming from distant galaxies.

Galaxy Forms New Stars With Extreme Efficiency

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.

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

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.

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

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.

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...
