New Evidence Explains How The 'Pillars Of Creation' Came Into Being
2014-06-27 06:48:02

The ‘Pillars of Creation’ is one of the most famous images made with the Hubble Space Telescope. It shows cooler interstellar gases being eroded by intense radiation and wind from nearby massive stars.

Star Cluster Study Inspires New Ideas On How Sun-Like Stars Form
2014-05-08 10:15:43

The prevailing theory on star cluster formation states that gravity causes a giant cloud of gas and dust to condense to concentrations that trigger the ignition of stars at the center of the cloud.

WASHINGTON, May 7, 2014 /PRNewswire-USNewswire/ -- Using data from NASA's Chandra X-ray Observatory and infrared telescopes, astronomers have made an important advance in the understanding of

Protostars In Orion Nebula Doomed By Larger Stars
2014-03-11 06:11:18

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found that some protostars in the Orion Nebula are doomed from the beginning.

Red Dead Redemption: Black Holes Bully Galaxies Into Submission
2014-02-26 15:13:15

Typically filled with only the oldest stars, which are relatively low in mass and appear red, giant elliptical galaxies have long baffled astronomers. These galaxies are mysteriously shut down with respect to star-forming activity

Snake Nebula

Astronomers using the Smithsonian's Submillimeter Array telescope have imaged the most detailed look yet of stellar nurseries within the Snake nebula.

Astronomers Discover Drastic Chemical Change In The Birth Of A Planetary System
2014-02-14 04:33:39

A team of scientists led by the University of Tokyo say that the chemical compositions of an interstellar cloud and the disk are not identical.

Active Supermassive Black Holes Discovered In Two Merging Galaxies
2014-01-28 13:17:31

Astronomers publishing a paper in the Astrophysical Journal say they have found that two merging galaxies have active supermassive black holes.

Massive Star Formation Mystery Solved
2014-01-28 04:04:20

Enormous young stars, which have over 10 times the mass of the Sun, shine brilliantly in ultraviolet wavelengths, energizing the gas around them, and it has long been a mystery why this superheated gas doesn't explode outwards.

NASA's Hubble Telescope Looks Deep Inside The Tarantula Nebula
2014-01-10 09:14:19

The Hubble Tarantula Treasury Program from NASA has revealed some fascinating new images deep inside the Tarantula Nebula, also known as 30 Daradus.

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...
