It lies about 145,000,000 light years away in the constellation Centaurus. Astronomers have not yet “seen” the black hole at the centre of NGC 4696, a galaxy in the constellation Centaurus. The image shows a region about 45,000 light years across. It is speculated that this black hole emits energy that heats up the surrounding gas, pushing cooler filaments of gas and dust outward and stopping star formation.
Show image source This image, taken by the Hubble Advanced Camera for Surveys, shows NGC 4696, the largest galaxy in the Centaurus cluster. Like most galaxies, NGC 4696 contains a central supermassive black hole.
Does NGC 1705 form stars?
NGC 1705 is a peculiar lenticular galaxy and a blue compact dwarf galaxy (BCD) in the southern constellation Pictor, less than one degree east of Iota Pictoris, and is located in a starburst. The large diamonds and large square on the right represent the measurements for NGC 1705 and NGC 1569, respectively, along with their 2σ errors. Hubble observations of the stars in NGC 1705 and other nearby irregular galaxies show that these galaxies are several thousand million years old. The central region of the small galaxy NGC 1705 glows with the light of thousands of young and old stars in this image taken by NASA’s Hubble Space Telescope.
What kind of galaxy is NGC 1705?
The central region of the small galaxy NGC 1705 shines with the light of thousands of young and old stars in this image taken by NASA’s Hubble Space Telescope. The central region of the small galaxy NGC 1705 shines in the light of thousands of young and old stars. Evidence for this is the chemical homogeneity of most star-forming galaxies, in which the expected spatial variations in oxygen abundance are not observed despite the presence of several massive star clusters (Kobulnicky & Skillman 1997, 199). As mentioned earlier, we must assume that the winds driving the evolution of NGC 1705 are differential, i.e. you can refuse to give a name, in which case the comment is assigned to any star.
What kind of galaxy is NGC 3982?
NGC 3982 is a member of the M109 group, a group of galaxies in the constellation Ursa Major that can include over 50 galaxies. Since a supernova occurs in a typical spiral galaxy (approximately) every 100 years, astronomers have software that uses high-resolution automated survey cameras to continuously monitor images of galaxies like NGC 3982 to detect supernova explosions early. They have imaged the spiral galaxy NGC 3982 and hundreds of other galaxies in the hope that one of the millions of stars in these images will one day explode as a supernova. The following image is of NGC 3982 from the Digitised Sky Survey 2 (DSS2 – see imprint), taken in the red channel.
