... December 23, 1998 . Ring Around the Galaxy . ... Explanation: It is difficult to hide one galaxy far behind another. The closer galaxy's gravity will act like a huge lens , pulling images of the background galaxy around both sides. This is just the case observed in the above recently released image from the VLT : the red galaxy in the middle is in the foreground, lensing the image of the background green galaxy into surrounding contorted arcs . ...

... The Far Infrared Sky . ... Three major sources contribute to the far-infrared sky: our Solar System, our Galaxy, and our Universe. The above recently released image, in representative colors, is the highest resolution projection yet created of the entire far-infrared sky (60 - 240 microns) created from years of observations by the now-defunct robot spacecraft COBE. ...

In this gallery are many images of Low Surface Brightness Galaxies which have recently been discovered and analyzed. ... The central surface brightness of this galaxy is 24.28 . Malin 2 This galaxy is another huge disk galaxy with a scale length of 15 kpc and a redshift of 15000 km/a. The high surface brightness knot in one of its spiral arms actually has the same color, luminosity and H-alpha equivalent width as the entire Large Magellanic Cloud . ... Truly it is a Low Surface Brightness Galaxy. ...

It is especially hard to explain this process of star birth in some spiral galaxies. ... Targets include both star clusters and galaxies, and star formation rates seen range from the starburst galaxy M82 (the Cigar Galaxy) which is creating about ten new stars in its core alone every year to the much less fecund star producer NGC 2841. ...

... By means of deep optical images obtained at the Special Astrophysical Observatory 6-m telescope it was discovered that some Seyfert galaxies that were earlier considered to be non-interacting objects displayed signatures of elongated tidal envelopes belonging to satellite debris. ... Our results suggest that statistic studies based on popular imaging surveys (for example SDSS) can lead to an underestimation of the fraction of minor mergers among galaxies with active nuclei (AGN). ...

Discover the cosmos! ... December 6, 1999 . M83: The Southern Pinwheel Galaxy from VLT . ... Explanation: M83 is one of the closest and brightest spiral galaxies on the sky. Visible with binoculars in the constellation of Hydra , majestic spiral arms have prompted its nickname as the Southern Pinwheel. Although discovered 250 years ago, only in this century was it appreciated that M83 was not a gas cloud but a barred spiral galaxy much like our own Milky Way Galaxy . ... About APOD > . ...
