... Most stars form in clusters, so the simple picture of star formation needs to incorporate the impact that young stars have on their environments, and each other. One region we study is NGC 1333, shown to the left as seen by the Spitzer Space Telescope. This is a тАЬproto-typicalтАЭ star-forming region located тАЬonlyтАЭ 1000 light years away in the direction of the constellation Perseus. ... Copyright 2015 Adele Plunkett. ...

4. Astronomy Magazine, July 1998
Image -- Jim Flood, Max Mutchler (Space Telescope Science Institute), and NASA. The Hubble image shows clusters of hot, young, blue stars in a 3,000 light-year segment of NGC 1808's starburst region. The ground-based image shows a faint halo surrounding the galaxy's disk - the aftereffect of dust filaments being ejected from the core by massive stars that exploded as supernovae in the starburst region. ... 1 April 1998 . for the July 1998 edition of Astronomy magazine) ...

5. The Electron Pressure Differential between the Sunspot Plume and the
... It was shown in the early 1980's that spectral lines formed around 1-2.5 x 10 5 K were enhanced in radiance by factors up to 15-25 over the normal quiet Sun. From the dynamical viewpoint, this would suggest a pressure imbalance between the sunspot and the surrounding region. ... Here, the electron density was evaluated over a bright sunspot plume region using lines within the O V 760? multiplet. ... The derived densities in all four regions are indicated. ...

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. ...

10. Density Determination
In order to measure the density of the Universe, it is necessary to sample a region that is larger than the scale on which the Universe becomes approximately homogeneous. ... When applied to clusters of galaxies we find a mass to luminosity ratio that implies a density of the Universe that is about 0.3 times the critical density. ... Thus the mass-to-muinosity ratio appears to vary with the size of the region measured, from 3 in the solar neighborhood to 30 in galaxies to 300 in clusters of galaxies. ...

... The large field size of UIT is ideal for studies of globular clusters. ... Very metal poor clusters are conducive for the formation of very hot horizontal branch stars which radiate most of that energy in the UV part of the spectrum. ... M31 is the nearest large spiral galaxy to us. ... These are small dwarf galaxies and NGC 205 is a bit unusual because it still has retained some gas for star formation despite its low mass. M33 is an actively star forming spiral galaxy in the local group. ...
