Latest H II region Stories
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.
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.
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.
The Hubble Tarantula Treasury Program from NASA has revealed some fascinating new images deep inside the Tarantula Nebula, also known as 30 Daradus.
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.
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.
A new image released by the European Space Observatory 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.
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.
A new image taken by the European Space Observatory's La Silla Observatory shows off a stellar nursery nicknamed the Seagull Nebula.
Astronomers studying the Milky Way have discovered a large number of previously-unknown regions where massive stars are being formed.
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 Ã‰douard 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...
