ESO astronomers using the Very Large Telescope (VLT) reported today that they have captured a detailed image of the Toby Jug Nebula.

Sharpest Ever Image Of Prawn Nebula Unveiled
2013-09-18 10:42:57

Astronomers using the Very Large Telescope at the European Southern Observatory's Paranal Observatory in Chile have taken the sharpest image ever of the Prawn Nebula.

Magnetic Jets Stars Final Transformation
2013-09-17 12:37:48

New observations of magnetic jets may shed some light on how stars transition into planetary nebulae.

Bizarre Alignment Observed In Butterfly-Shaped Nebulae
2013-09-04 08:57:07

Planetary nebulae occur in the final stages of a star's life when its outer layers begin to stretch out into the surrounding space. These nebulae can create beautiful objects in the night sky, with some stretching out into an hourglass or butterfly shape.

Not All Rogue Planets Are Born Within Solar Systems
2013-08-20 11:30:55

A team of astronomers say free-floating planets can be born freely, outside of an existing solar system -- a discovery that contradicts previous beliefs they must be ejected from host systems.

Life Of Eskimo Nebula Coming To A Beautiful End

At the end of their lives, stars like our Sun become remarkably photogenic. For example, NGC 2392, located approximately 4,200 light years from Earth, is giving astronomers a beautiful display as it nears the end of its existence.

Cats Paw Nebula Baby Boom

Astronomers presented research on Wednesday at the American Astronomical Society (AAS) about how the Cat's Paw Nebula is experiencing a "baby boom."

NGC 6334: Shedding Light On Starburst Regions
2013-06-05 13:00:40

Stars are formed in massive clouds of gas that are being compressed by some nearby event. Over time, the region will be consumed by the forming stars, leaving a cluster that will eventually drift apart. But what starts this process in the first place?

Hubble Provides Most Detailed Image Of Ring Nebula To Date
2013-05-23 12:48:25

The Hubble Space Telescope has provided one of the most detailed images of the Ring Nebula so far, allowing scientists to construct a model of the nebula in 3D.

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 -- A star is a self-gravitating sphere of plasma in hydrostatic equilibrium that generates energy in its interior through the process of nuclear fusion. Energy from this process radiates into space as electromagnetic radiation and neutrinos. Star formation and evolution As learned by star formation astronomers, stars are born in molecular clouds, regions of higher density of matter, and form by gravitational instability inside those clouds. High mass stars illuminate powerfully...

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...
