Latest Star formation Stories
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 to hide the stars.
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 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.
An unusually dense cloud located near the center of the galaxy does not appear to be forming any massive stars.
Using the airborne telescope on the Stratospheric Observatory for Infrared Astronomy, astronomers have learned that a series of recent starbursts had taken place in the central region of the Milky Way.
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.
The youngest still-forming solar system ever seen has been discovered by astronomers and reported about in the journal Nature.
A team from Max Planck Institute for Astronomy has observed the earliest stages of star formation using the European Space Agency's Herschel Space Observatory.
The European Space Agency (ESA) said its Herschel space observatory found a gas and dust cloud that contains enough water vapor to fill Earth's oceans more than 2,000 times over.
A new image taken by the European Space Agency’s Herschel space observatory, shows off two nebulous blue orbs in the Vela C region.
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...
