Galactic Center And The Pigtail Molecular Cloud
2012-09-05 11:06:34

Astronomers using a telescope at the National Astronomical Observatory of Japan have discovered a molecular cloud that has a peculiar helical structure.

Chandra Finds Young Supernova Remnant Spitting Out X-rays
2012-07-31 05:18:12

In a galaxy not that far away, astronomically speaking at least, researchers using NASA's Chandra X-ray Observatory have detected the first x-rays emitted by the debris of a young supernova, SN 1957D.

New Hubble Image Shows Space Geyser
2012-07-03 14:32:32

The Hubble Space Telescope has unleashed a new image of a geyser of hot gas flowing from a newborn star.

Astronomers Spot Fastest Moving Pulsar Ever

Researchers may have discovered the fastest moving pulsar ever seen using NASA's Chandra X-ray Observatory and ESA's XMM-Newton.

Hubble Images Searchlight Beams From A Preplanetary Nebula
2012-04-27 09:52:56

The NASA/ESA Hubble Space Telescope has been at the cutting edge of research into what happens to stars like our sun at the ends of their lives.

Spitzer Telescope Finds Hidden Jet

NASA's Spitzer Space Telescope took this image of a baby star sprouting two identical jets (green lines emanating from fuzzy star).

Image 1 - Planck Getting Closer To The Cosmic Blueprint
2012-02-13 07:23:13

ESA’s Planck mission has revealed that our Galaxy contains previously undiscovered islands of cold gas and a mysterious haze of microwaves. These results give scientists new treasure to mine and take them closer to revealing the blueprint of cosmic structure.

Image 1 - New Facets Of The Vela Pulsar Wind Nebula

An international team of scientists led by University of Hawai'i at Mānoa Professor Ralf I. Kaiser, Alexander M. Mebel of Florida International University, and Alexander Tielens of Leiden Observatory in the Netherlands, discovered a novel chemical route to form polycyclic aromatic hydrocarbons (PAHs) – complex organic molecules such as naphthalene carrying fused benzene rings – in ultra-cold regions of interstellar space.

Image 1 - Fermi Shows That Tycho's Star Shines In Gamma Rays
2011-12-13 11:56:08

In early November 1572, observers on Earth witnessed the appearance of a "new star" in the constellation Cassiopeia, an event now recognized as the brightest naked-eye supernova in more than 400 years.

Supernova Remnant -- A supernova remnant (SNR) is made up of the materials left behind by the gigantic explosion of a star in a supernova. There are two possible routes to this end: either a massive star may cease to generate fusion energy in its core, and collapse inward under the force of its own gravity, or a white dwarf star may accumulate material from a companion star until it reaches a critical mass and undergoes a similar collapse. In either case, the resulting supernova...

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...

Reflection Nebula -- In astronomy, reflection nebulae are clouds of dust which are simply reflecting the light of a nearby star or stars. The nearby star or stars are not hot enough to cause ionization in the gas of the nebula like in emission nebulae but are bright enough to give sufficient scattering to make the dust visible. The distiction between these two types of nebulae was done by Hubble in 1922. They are usually blue because the scattering is more efficient for blue light...

Planetary Nebula -- A planetary nebula is an astronomical object that usually appears nebulous and disk-like in low-resolution observations. Because of this appearance, similar to the appearance of planets in early observations, the "planetary" adjective was attached and has since been retained for historical consistency. According to current observations and models, planetary nebulae in fact have little to do with planets. Instead, as a small star (less than a few times the mass...

Nebula -- in astronomy, observed manifestation of a collection of highly rarefied gas and dust in interstellar space. Prior to the 1960s this term was also applied to bodies later discovered to be galaxies, e.g., the so-called Great Nebula in the constellation Andromeda. In 1864, William Huggins confirmed William Herschel's conclusion that nebulae are not swarms of stars by determining that the spectra of nebulae are made of bright lines characteristic of radiating gases. Diffuse...
