star formation region Gum 15
2014-07-02 10:48:50

European Southern Observatory The little-known cloud of cosmic gas and dust called Gum 15 is the birthplace and home of hot young stars. Beautiful and deadly, these stars mold the appearance of their mother nebula and, as they progress into adulthood, will eventually also be the death of her. This image was taken as part of the ESO Cosmic Gems program [1] using the Wide Field Imager on the MPG/ESO 2.2-meter telescope at the La Silla Observatory in Chile. It shows Gum 15, located in the...

Monkey Head Nebula
2014-03-17 14:27:53

NASA/ESA Hubble Space Telescope To celebrate its 24th year in orbit, the NASA/ESA Hubble Space Telescope has released a beautiful new image of part of NGC 2174, also known as the Monkey Head Nebula. This colorful region is filled with young stars embedded within bright wisps of cosmic gas and dust. NGC 2174 lies about 6400 light-years away in the constellation of Orion (The Hunter). Hubble previously viewed this part of the sky back in 2001, creating a stunning image released in 2011,...

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

Brett Smith for redOrbit.com - Your Universe Online 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. According to a new study in The Astrophysical Journal Letters, a group of scientists using the Jansky Very Large Array (VLA), a radio observatory in New Mexico, has validated theories that say as the gas cloud...

NASA's Hubble Telescope Looks Deep Inside The Tarantula Nebula

[ Watch the Video: Hubble Images Tarantula Nebula In New Detail ] Gerard LeBlond for redOrbit.com - Your Universe Online The Hubble Tarantula Treasury Program from NASA has revealed some fascinating new images deep inside the Tarantula Nebula, also known as 30 Daradus. This nebula is positioned inside the Large Magellanic Cloud 170,000 light-years away and contains some 800,000 stars and protostars. Upon completion of the program, a huge catalog of stellar properties will be...

Fiery Drama Of Star Birth And Stellar Death
2013-11-27 07:05:14

ESO The Large Magellanic Cloud is one of the closest galaxies to our own. Astronomers have now used the power of ESO’s Very Large Telescope to explore one of its lesser known regions. This new image shows clouds of gas and dust where hot new stars are being born and are sculpting their surroundings into odd shapes. But the image also shows the effects of stellar death — filaments created by a supernova explosion. Located only about 160 000 light-years from us in the constellation of...

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

[ Watch the Video: Zooming In On The Prawn Nebula ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the Very Large Telescope (VLT) at the European Southern Observatory's (ESO) Paranal Observatory in Chile have taken the sharpest image ever of the Prawn Nebula. The stellar nursery, formally known as IC 4628, sits 6,000 light-years from Earth in the constellation of Scorpius. The new image shows clumps of hot new-born stars nestled among the clouds making up the...

Seagull Nebula Wings Shown In New ESO Image
2013-02-06 05:10:24

[ Video 1 ] | [ Video 2 ] Lee Rannals for redOrbit.com - Your Universe Online A new image released by the European Space Observatory (ESO) taken by its Wide Field Imager shows off a section of the Seagull Nebula. The cloud of dust and glowing gas seen in the image that forms the "wings" of the seagull reveals a mix of dark and glowing red clouds. The Seagull Nebula, or IC 2177, lies between the constellations of Canis Major and Monoceros in the southern sky. Astronomers refer to...

Milky Way Star Formation Survey Yields Surprising Results
2013-01-10 09:33:34

[ Watch the Video: HII Region Discovery Survey ] redOrbit Staff & Wire Reports - Your Universe Online A new survey of the Milky Way has uncovered hundreds of previously-unknown regions of massive star formation, including some of the most distant located to date in the galaxy, researchers revealed on Wednesday. Using the National Science Foundation's (NSF) Green Bank Telescope (GBT) in West Virginia and the Arecibo Observatory Telescope in Puerto Rico, as well as data from the...

Seagull Nebula

Watch the Video: [ Zooming in on the Seagull Nebula ] Watch the Video: [ Panning Across the Head of the Seagull Nebula ] Lee Rannals for redOrbit.com - Your Universe Online A new image taken by the European Space Observatory's La Silla Observatory shows off a stellar nursery nicknamed the Seagull Nebula. This nebula looks like the head of the seagull, and glows brightly due to the energetic radiation from a hot young star that sits at its heart. Nebulae are interstellar...

Astronomers studying the Milky Way have discovered a large number of previously-unknown regions where massive stars are being formed. Their discovery provides important new information about the structure of our home Galaxy and promises to yield new clues about the chemical composition of the Galaxy. "We can clearly relate the locations of these star-forming sites to the overall structure of the Galaxy. Further studies will allow us to better understand the process of star formation and to...

Stephan's Quintet in the constellation Pegasus is a visual grouping of five galaxies which four form the first compact galaxy group ever discovered. The group was discovered by Édouard Stephan in 1877 at Marseilles Observatory and is the most studied of all the compact galaxy groups. NGC 7320, which has extensive H II regions, is the brightest member of the visual grouping and is where active star formation is occurring. Hickson Compact Group 92, which contains four of the five...

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...

Triangulum Galaxy -- The Triangulum Galaxy, Messier object M33, is a spiral galaxy of type Sc located in the constellation Triangulum. Triangulum is small relative to its larger neighbors such as the Milky Way and Andromeda Galaxy, but is about average compared to most spiral galaxies in the universe. Triangulum is a member of the Local Group of galaxies and may be a gravitationally bound companion of the Andromeda Galaxy. LGS 3, one of the small Local Group member galaxies, is itself...
