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. ...

... Scientists from G. I. Budker Institute of Nuclear Physics- Syberian Branch of the Russian Academy of Science, Novosibirsk State University, Novosibirsk State Technical University, Samara State Aerospace University (SSAU) and Image Processing Systems Institute (IPSI) of the Russian Academy of Science, became the first people in the world obtained terahertz non-diffractive twisted Bessel beams and used them for the first time the formation of surface electromagnetic waves on the metal surface. ...

I-GALFA View of a Galactic Tangent Region . ... Image featured in NAIC Newsletter #46 . I-GALFA image of hydrogen gas in a tangent region outside the Sagittarius arm. ... Because we are viewing this gas in a direction closely aligned with (tangent to) its orbital motion, it appears to be moving away from us (we are orbiting the Galactic center with a similar speed, but our own motion in a different direction). ... The gas near 60 degrees longitude is being viewed tangent to its orbital motion. ...

Umbriel . Uranus II . Umbriel [UM-bree-ul] is the darkest satellite of Uranus. It is about the same size as Ariel and has about the same density. The surface appears to be old with large craters and does not change much from one location to another. Near the top is a puzzling bright ring called the fluorescent cheerio . ... Dark regions are represented as red and bright regions are represented as blue. The two white regions are bright ejecta from two fresh craters. ...
