Because the SparsePak data detect the warm ionised gas component in NGC 3310, these data suggest that NGC 3310 has maintained its disk structure and rotation in the star-forming component of its disk despite recent significant mergers with this system. Because the SparsePak data detect the warm ionised gas component in NGC 3310, these data suggest that NGC 3310 has maintained its disk structure and rotation in the star-forming component of its disk despite recent extensive mergers with this system. In most galaxies, however, the stars are separated by age, making it difficult to classify distant stars. Wikipedia NGC 3310 is a large-scale spiral galaxy in the constellation Ursa Major.
The fact that some regions are still much redder than the underlying disk stars suggests that they do not originate from the disk of NGC 3310.
How old is NGC 4889?
During its active period, astronomers would have classified NGC 4889 as a quasar, and the disk around the supermassive black hole would have emitted up to a thousand times the energy output of the Milky Way. The ionised medium detected around the black hole suggests that NGC 4889 may have been a quasar in the past. The first known observation of NGC 4889 was made in 1785 by Frederick William Herschel I, who was assisted by his sister Caroline Lucretia Herschel and included it in the Catalogue of Nebulae and Clusters of Stars published a year later. Although NGC 4889 is much larger than NGC 4886, its core appears to be much less dense than that of NGC 4886.
How heavy is NGC 4889?
Using instruments from the Keck II Observatory and the Gemini North Telescope, astronomers have measured the speed of stars moving around the centre of NGC 4889. For this particular black hole in the galaxy NGC 4889, scientists used instruments from the Keck II Observatory and the Gemini North Telescope to measure the speed of stars moving around the centre of the galaxy. However, because NGC 4889 is a spheroid rather than a flat spiral, it has a three-dimensional profile, so it could be as large as 15 trillion solar masses. The black hole at the centre of NGC 4889 is one of the largest ever discovered, but it is currently dormant.
A new photo of the galaxy NGC 4889 may look peaceful from so far away, but it actually hosts one of the largest black holes astronomers have ever identified.
What is NGC s33?
NGC 3310 is located towards the constellation Ursa Major and is about 59 million light years from Earth. It is a catalogue of 31 diffuse nebulae and 36 stellar emission line objects in the irregular galaxy NGC 6822 of the Local Group. The 36 stellar emission line objects in NGC 6822 appear to be emission line stars, small H ıı-spheres and planetary nebulae. The objects were identified from several broadband and interference filter plates of NGC 6822 taken with CTIO’s 4 m telescope at prime focus under excellent seeing.
It is one of a loose cluster of about six or seven dozen galaxies located towards the Big Dipper in the constellation Ursa Major (the Great Bear).
How did the Hubble telescope find black holes?
This invisible component could only consist of the remnants (white dwarfs, neutron stars and black holes) of massive stars whose interiors collapsed under their own gravity after their nuclear fuel was exhausted. The study not only revealed the feeding habits of the black hole at the centre of NGC 1566, but also showed that the swirling filaments of dust could cause the darkening of the centres of many galaxies when their black holes are active at the core. Hubble, born in 1889, discovered that many objects previously thought to be clouds of dust and gas and classified as nebulae were actually galaxies beyond the Milky Way. This instrument made it much easier to observe the region near the centre of a galaxy and to detect the rapid movements of stars orbiting near a black hole.
