NGC 6789 is a void [4] irregular galaxy in the constellation Draco. It was discovered by Lewis Swift on Aug 30, 1883. [5] It is located within the Local Void, a region of space with far fewer galaxies than its surroundings. [4] NGC 6789 is the nearest blue …

NGC 6789 is a Elliptical Galaxy located in the constellation of Draco in the northern hemisphere. NGC 6789's distance from Earth is 11,007,777.75 light years. NGC 6789 is called NGC 6789 in the New General Catalogue (NGC).

2001年4月12日 · We find that NGC 6789 is the most nearby example of a blue compact dwarf galaxy known to date. With the help of the Wide Field Planetary Camera 2 aboard the Hubble Space Telescope, we resolve NGC 6789 into over 15,000 point sources in the V and I bands. The young stars of NGC 6789 are found exclusively near the center of the galaxy.

NGC 6789 is the nearest BCD galaxy to us. Blue compact dwarf galaxies (BCDs) are small, faint, and blue starburst galaxies. They have little dust. They are blue because they contain massive young stars that emit high energy radiation.

NGC 6789 is a Irregular Galaxy in the Draco constellation. NGC 6789 is situated close to the northern celestial pole and, as such, it is visible for most part of the year from the northern hemisphere. Given its B magnitude of 13.76, NGC 6789 is visible with the help of a telescope having an aperture of 14 inches (350mm) or more.

We present a detailed auto-consistent study of the nearest blue compact dwarf galaxy NGC 6789 by means of optical and ultraviolet (UV) archive photometry data a

NGC 6789 is a very small irregular galaxy in eastern Draco about 11 to 12 million light-years distant. This was determined by the Tip of the Red Giant Branch method using HST data. Redshift is useless at this close distance and in fact, the galaxy …

2018年6月24日 · NGC 6789 (UGC 11426, VV 414 and others) is a blue compact dwarf galaxy located approximately 12 million light-years away in Draco. 390 minutes total exposure – 6 hours 30 minutes. Imaged June 11th, 17th and 18th, 2018 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on …
