Astronotes Armagh Planetarium's Stellar Blog! ... Stars . ... Starbursts are short-lived events, stars are forming so quickly that the reservoirs of interstellar gas from which stars are coalescing would be used up on a timescale much shorter than the age of the galaxy . ... Strong stellar winds from giant new stars in the starburst region combine with the blasts of supernovae to push a mighty flood of extremely hot gas, a ?superwind? from the galaxy thousands of light years into intergalactic space. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... STScI-PRC01-07 NGC 4013: A GALAXY ON THE EDGE NASA's Hubble Space Telescope has snapped this remarkable view of a perfectly "edge-on" galaxy, NGC 4013. This new Hubble picture reveals with exquisite detail huge clouds of dust and gas extending along, as well as far above, the galaxy's main disk. ... Dark clouds of interstellar dust stand out in the picture because they absorb the light of background stars. ... Dark interstellar clouds are believed to be where new stars are formed. ...

... Stars are born in big clouds of gas and dust in the Universe. ... This amazing new picture shows a small part of a cloud in our own galaxy (called the Milky Way) in which stars are being formed. In the picture you can see bright arc shapes in the cloud, but what created them is a mystery. ... When all of their fuel is gone, these massive stars explode in what is called a supernova explosion the biggest firework display in the Universe! ...

... The Large Magellanic Cloud is a Dwarf Irregular galaxy in orbit around our own Milky Way. It is a large object, several degrees in size, and easily visible to the unaided eye in Southern Hemisphere skies. The LMC is located in the constellation of Doradus at about 5h30m Right Ascension, -68 degrees Declination, and lies at a distance of roughly 50 kiloparsecs (160,000 light years) from Earth. ...

. A Hubble Space Telescope image shows the Ultraluminous Infrared Galaxy Arp 220, about 250 million light-years away in the constellation Serpens. The image shows the dust-obscured starlight from hundreds of star clusters in a small region of the galaxy about 5,000 light-years across. At the center of the image are two bright knots, where researchers detected magnetic fields. NASA, ESA, and C. Wilson (McMaster University, Hamilton, Ontario, Canada)

Without an optical afterglow, a galaxy within the 2 arc second error region of a GRB x-ray afterglow is identified as a host galaxy; however confusion can rise due to the facts that 1. the edge of a galaxy is diffused, 2. multiple sources could exist within 2 arc second error region, 3.the distance between the galaxy and the x-ray afterglow is measured by projection, and 4. lensing causes increase of brightness and position shifts. ...
