Spiral Galaxy ESO 498-G5

Hubble See Spiral Galaxy ESO 498-G5

NASA’s Hubble Space Telescope captured the image of the spiral galaxy known as ESO 498-G5. One interesting feature of this galaxy is that its spiral arms wind all the way into the center, so that ESO 498-G5’s core looks like a bit like a miniature spiral galaxy. This sort of structure is in contrast to the elliptical star-filled centers of many other spiral galaxies, which instead appear as glowing masses. Astronomers refer to the distinctive spiral-like bulge of galaxies such as ESO 498-G5 as disc-type bulges, or pseudobulges, while bright elliptical centers are called classical bulges.

Hubble Image Show Spiral Galaxy NGC 4980

This image, which shows NGC 4980, is composed of exposures taken in visible and infrared light by Hubble’s Advanced Camera for Surveys. The image is approximately 3.3 by 1.5 arcminutes in size.NGC 4980 is a spiral galaxy in the southern constellation of Hydra. The shape of NGC 4980 appears slightly deformed, something which is often a sign of recent tidal interactions with another galaxy. In this galaxy’s case, however, this appears not to be the case as there are no other galaxies in its immediate vicinity.

Galaxy NGC 3810

New study finds that supernova explosions and the jets of a monstrous black hole are scattering a galaxy’s star-making gas like a cosmic leaf blower. The findings, which relied on ultraviolet observations from NASA’s Galaxy Evolution Explorer and a host of other instruments, fill an important gap in the current understanding of galactic evolution. It has long been known that gas-rich spiral galaxies like our oun smash together to create elliptical galaxies such as the one observed in the study.

Astronomers Discovered Rare Dwarf Galaxy

An international team of astronomers from Australia, Germany, Switzerland, and Finland has discovered a rare dwarf galaxy, called LEDA 074886, which has a striking resemblance to an emerald cut diamond. The astronomers discovered the rectangular shaped galaxy within a group of 250 galaxies some 70 million light years away. As said Associate Professor Alister Graham from Swinburne University of Technology in the Universe around us, most galaxies exist in one of three forms: spheroidal, disc-like, or lumpy and irregular in appearance.
