... GALEX: The Andromeda Galaxy . ... A mere 2.5 million light-years away, the Andromeda Galaxy really is just next door as large galaxy's go. So close, and spanning some 260,000 light-years, it took 11 different image fields from the Galaxy Evolution Explorer (GALEX) satellite's telescope to produce this gorgeous portrait of the spiral galaxy in ultraviolet light. ... In fact, the rich stellar nursery already holds the massive star cluster known as the Cygnus OB2 association. ... Sun vs Super Moon . ...

... Missions . HST . ... Research . ... The key questions I would like addressed in my section include: 1) What are the remaining plausible models that explain the faint blue counts in both the field and cluster and are dwarfs necessary in these models? How much evolution is actually needed? ... 2) Showing some Keck redshift and kinematic data of very faint blue galaxies, as well as complementary HST structure and morphology that address the issue of faint blue galaxies being dwarfs. ...

... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

... Deutsch . ... The Milky Way is the galaxy in which we live, a collection of billions of hot burning stars, planets and cosmic gas. If you re lucky enough to have enjoyed a really dark sky, far from the light pollution in cities and towns, you might have seen the Milky Way arching majestically across the night sky. ... This star cluster lies in the Carina-Sagittarius arm, named after the two constellations we find it in (the Carina constellation and the Sagittarius constellation). ...

The ESA/ESO Astronomy Exercise Series 2 . The Distance to Messier 100 as Determined by Cepheid Variable Stars . ... The small variations in distance to the individual Cepheid variable stars in the Cloud are negligible compared with the much larger distance to the SMC. ... In this way Cepheid variable stars can be used as one of the 'standard candles' in the Universe that act either as distance indicators themselves or can be used to calibrate (or set the zero point for) other distance indicators. ...

... We have measured this "redshift" for the pink black holes, and allowed for it in our calculations. ... We see this effect in the emission from gas around these pink black holes, but it is far too small an effect to account for the pinkness. Thus the swirling motions of gas around or into the black holes cannot produc the colour. ... At first we thought that these things were normal blue black holes hidden behind clouds of interstellar dust, that absorbed the blue light and made them appear pink. ...

... STScI-PRC01-04 HUBBLE'S ULTRAVIOLET VIEWS OF NEARBY GALAXIES YIELD CLUES TO EARLY UNIVERSE Astronomers are using these three NASA Hubble Space Telescope images to help tackle the question of why distant galaxies have such odd shapes, appearing markedly different from the typical elliptical and spiral galaxies seen in the nearby universe. ... Light from these galaxies travels great distances (billions of light-years) to reach Earth. ... These stars emit mostly ultraviolet light. ...

High redshift radio galaxies and SMBH evolution Mark Lacy Outline - what did we learn in the last 10 years? Radio galaxies contain really big black holes. ... Some high-z radio galaxies are forming a lot of stars. Radio jets can both drive strong shocks into the ISM (negative feedback for star formation?) and form stars (positive feedback for star formation?) High-z radio galaxies are not alone - radio quiet and radio intermediate type-2 quasars are common at high redshifts. ...

... 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. ...
