網頁D) The keeping of accurate time. D- Distant stars are obscured by dust in interstellar space. 2. Why are we able to see only a relatively small part of our Galaxy, the Milky Way Galaxy? A) There are so many stars in our Galaxy that the more distant ones are hidden behind the nearer ones.

This artificial-color mosaic of 30 images taken with the Chandra X-ray satellite shows a region 400 × 900 light-years in extent and centered on Sagittarius A*, the bright white source in the center of the picture. The X-ray-emitting point sources are white dwarfs, neutron stars, and stellar black holes. 網頁2024年6月10日 · The newly detected wandering black hole lies about 5,000 light-years away, in the Carina-Sagittarius spiral arm of our galaxy. However, its discovery allows astronomers to estimate that the nearest isolated stellar-mass black hole to Earth might be as close as 80 light-years away. The nearest star to our solar system, Proxima Centauri, …

網頁2011年6月21日 · As mentioned in Section 2.1, some studies of the inner Galaxy prefer models with a central ‘hole’ in the disc (e.g. Picaud & Robin 2004).We do not consider such models here. The kinematic data we consider is all related to parts of the Galaxy which lie outside any central disc hole, so, in this study, a model with a central hole should simply …

The mass distribution within the Milky Way closely resembles the type Sbc in the Hubble classification, which represents spiral galaxies with relatively loosely wound arms. Astronomers first began to conjecture that the Milky Way is a barred spiral galaxy, rather than an ordinary spiral galaxy, in the 1960s.
