1. APOD: 2004 November 16 - Sagittarius Dwarf Irregular Galaxy
... 2004 November 16 . Sagittarius Dwarf Irregular Galaxy . ... ESA , NASA . Explanation: How old is this galaxy? The nearby Local Group galaxy dubbed the Sagittarius Dwarf Irregular Galaxy (SagDIG) is not only very small but also has relatively few elements more massive than helium . Now the lack of heavy elements might mean that SagDIG is very young, so that component stars had little time to create and disperse massive elements. ... About APOD | ... NASA Official: Jay Norris. ...

2. Sagittarius Dwarf Irregular Galaxy
... ESA , NASA Explanation: How old is this galaxy? The nearby Local Group galaxy dubbed the Sagittarius Dwarf Irregular Galaxy (SagDIG) is not only very small but also has relatively few elements more massive than helium . ... Although SagDIG does have some groups of young stars, many stars are very old, and the galaxy as a whole helps astronomers to understand how the universe evolved , and show that at least one metal-poor galaxy is almost as old as the universe. ...

4. The Galaxy Gallery Page 6: Comparative Morphology
Star formation is often best manifested by bright H II regions.These are regions of hydrogen which have been ionized by ultraviolet photons which are emitted from massive stars (typically stars more than 20 times the mass of the Sun). ... A narrowband filter image centered on this wavelength will then readily reveal these H II regions and hence the current sites of star formation in a galaxy, The luminous blobs that can be seen here are all H II regions . ...

5. Discovery of an isolated dwarf spheroidal galaxy neighboring the Local Group
... Our recent observations with the Hubble Space Telescope (August 29, 2014) led to revealing a highly isolated dwarf spheroidal galaxy KKs 3 situated at a distance of 2.12 0.07 Mpc from the Milky Way. The dSph galaxy locates on the southern sky (RA=02 h 24 m 44.4 s , Dec.= ... Over the last decade, about 30 dSph galaxies have been discovered inside the Local Group through systematic search in the vicinity of M31 and more that a dozen dSphs were discovered in the nearby group around M81. ...

8. Hubble Uncovers Dust Disk Around a Massive Black Hole (STScI-PRC98-22) A
... Resembling a gigantic hubcap in space, a 3,700 light-year-diameter dust disk encircles a 300 million solar-mass black hole in the center of the elliptical galaxy NGC 7052. ... Because the front end of the disk eclipses more stars than the back, it appears darker. ... Despite its size, the disk is 100 times less massive than the black hole. ... The bright spot in the center of the disk is the combined light of stars that have crowded around the black hole due to its strong gravitational pull. ...

18. (S-7a) The Black Hole at the Center of our Galaxy
... 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. ...

20. New Results Confirm Dark Galaxy Existence
... Confirmation that a mysterious cloud of hydrogen in the Virgo Cluster is a dark galaxy has been published by a team of astronomers . New evidence from NASA's Hubble Space Telescope and the Westerbork Synthesis Radio Telescope in the Netherlands has been used to rule out all but one of the ideas put forward to explain the existence of VIRGOHI 21, an intergalactic gas cloud 50 million light-years from the Earth. ... Only Dark Matter can account for the existence of such a system. ...
