... 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. ...

... This beautiful new image shows a glowing cloud of cosmic dust (called a nebula) sitting boldly against a backdrop of shining stars. To the naked eye, thick clouds like these appear empty and dark, but some are actually home to the brightest nebulae and hottest young stars in the Universe! Stars are made of gas, so it is no surprise that they are born inside thick gassy clouds. But the clouds that give birth to stars also block our view of them growing within. ...

... Micro Moon over Super Moon . 21.01.2014 . Did you see the big, bright, beautiful Full Moon last Wednesday night? ... On that night, the smallest Full Moon of 2014 reached its full phase only a few hours from lunar apogee, the time of its the most distant point from Earth in the Moon's elliptical orbit. ... How large do things appear when far away? When peering across the universe, the answer can actually tell us about its average gravitational history and hence its composition. ...

... This section highlights some typical FOC image characteristics. ... Occulting fingers located near the aperture entrance if the image size is greater than 512 x 512 pixels or if the FUV prism is in the beam. Reseau marks etched onto the faceplate of the detector to aid in geometric correction ( Figure 4.4 ). ... A faint diagonal parallel striping pattern called pattern noise . ... Warped edges ( Figure 4.4 ). ... Figure 4.5: FOC 512 x 512 Image Showing Faint "Thumbprint" Pattern or "Fringes" . ...

... 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. ...

Galaxies are diffuse objects which are imaged against a background of finite brightness and noise. Galaxies which have the maximum contrast with respect to this background are the ones that are first discovered. ... These galaxies have been missed to date but active surveys for them are underway. ... In this page we present several examples of these newly discovered Low Surface Brightness galaxies as well as examples of high surface brightness galaxies. ...

... August 24, 1996 . Why is QSO 1229+204 so Bright? Credit: J. Hutchings ( DAO ), NASA . Explanation: What causes the center of this barred spiral galaxy to light up brighter than almost anything in the universe? ... Not only was QSO 1229+204 at the core of an unusual barred spiral galaxy , but this galaxy was in the process of colliding with a dwarf galaxy . Gas from this collision quite possibly fuels a supermassive black hole causing QSO 1229+204 to shine so brightly. ... About APOD | ...

... STScI-PRC00-34 A BIRD'S EYE VIEW OF A GALAXY COLLISION What appears as a bird's head, leaning over to snatch up a tasty meal, is a striking example of a galaxy collision in NGC 6745. ... However, the situation is quite different for the interstellar media in the above two galaxies - material consisting largely of clouds of atomic and molecular gases and of tiny particles of matter and dust, strongly coupled to the gas. ... The hot blue stars in this image are evidence of this star formation. ...
