. This new NASA Hubble Space Telescope image of the Antennae galaxies is the sharpest yet of this merging pair of galaxies. During the course of the collision, billions of stars will be formed. The brightest and most compact of these star birth regions are called super star clusters. The new image allows astronomers to better distinguish between the stars and super-star clusters created in the collision of two spiral galaxies. NASA, ESA, the Hubble Heritage Team (STScI/AURA)-ESA

... This program was created for correlating chosen regions in the series of fts images. ... Chosen regions' . ... In this section the program counts the integral for each region of the grid for each image. ... As a matter of fact, the integral is total brightness of the region and it is counted by 'int_tabulated' IDL function. ... In addition, the program will show the count of the regions which correlate with the corresponding region (the brighter region means the bigger count) and its contour. ...

... This paper describes the main algorithms used by the Einstein Level One processing to create the exposure masks and the background maps for Einstein IPC images, and how these algorithms were recreated in the IRAF environment. Our goal was to recreate the algorithms used by the Level One Processing to create exposure masks and background maps for Einstein Image Proportional Counter (IPC) data (cf. sections 2.5 and 2.7 of Harnden et al. ...

... 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. ...

... The SAS task especget has been designed to allow extraction of source+background and background spectra, redistribution matrices, and effective area vectors from an EPIC event list with a single command. especget can be launched from the main xmmselect window, in which case an extraction region size optimization algorithm is also ran, which maximizes the signal-to-noise of the net source spectrum. ... When you are happy with your definition, click the button 1D region in the xmmselect window. ...

... 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. ...

... 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.

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! ...

An investigation of the spectral energy distribution (SED) of the compact steep-spectrum (CSS) source and possible radio-loud narrow-line Seyfert 1 galaxy (NLS1), PKS 2004-447, is presented. ... Analysis of a non-contemporaneous, low-resolution optical spectrum suggests that the narrow-line region (NLR) is much more reddened than the X-ray emitting region suggesting that the gas-to-dust ratio in PKS 2004-447 may be very different than in our own Galaxy. ...

. To remove a directory that is a symbolic link that points to another directory use the command: rm directory_name . Notice that the directory does not need to be empty and you do not have to use the rmdir command. You are not really removing a directory, just a named symbolic link that points to the "real" directory.
