... 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. ...

... Calibration and analysis of this observation posed very interesting challenges for the authors, in particular dealing with an exciting new instrument whose on-orbit calibration was not yet well defined. ... Five mosaic positions were observed during five consecutive orbits as well as observations for dark and flat calibration. ... Darks and flats had to be created from contemporaneous reference observations and problems within the calibration process had to be resolved. ...

An image of the grand design of spiral galaxy M100 obtained with NASA's Hubble Space Telescope resolves individual stars within the majestic spiral arms. ... Hubble has the ability to resolve individual stars in other galaxies and measure accurately the light from very faint stars. This makes space telescope invaluable for identifying a rare class of pulsating stars, called Cepheid Variable stars embedded within M100's spiral arms. ... 617) 495-7062 . Fax: (617) 495-7356 . ...

Dimitri ZVONKINE (Paris-7 Jussieu): Models of 2-dimensional gravity and enumeration of ramified coverings of the sphere . We explain why the enumeration of ramified coverings of the sphere provides a model of 2-dimensional gravity. ... We also prove some combinatorial results concerning ramified coverings of the sphere. ... It appears naturally in elementary graph enumeration problems, in the intersection theory on moduli spaces of stable curves, and in the enumeration of ramified coverings. ...

. This new image of the Hubble Ultra Deep Field (HUDF) 2012 campaign reveals a previously unseen population of seven faraway galaxies, which are observed as they appeared in a period 350 million to 600 million years after the Big Bang. The galaxy census is the most robust sample of galaxies ever found at these early epochs. The galaxies were seen in near-infrared light using Hubble's Wide Field Camera 3. // Credit: NASA/ESA/R.
