00,000 light-years, and width of 10,000 light-years. It contains billions of stars which include our sun. You can get a glimpse of the band of stars in the Milky Way from a dark place at night. Our solar system is located somewhere between the centre and the edge of the...
Dust and stars in the plane of the Milky Way create a "Zone of Avoidance" in the extragalactic sky. Galaxies are distributed in gigantic labyrinth formations, filaments and great walls with occasional dense clusters. They can be traced all over the sky, except where the dust within our own ...
However, these factors are unlikely to be able to explain an overabundance of stars, leaving scientists with no real way to explain the new results. related stories —Some of the oldest stars in the universe found hiding near the Milky Way's edge — and they may not ...
VizieR Online Data Catalog: Galaxies Behind the Milky Way (Saito+ 1990-91; Roman+ 1996-98) This catalogue gathers the searches for galaxies of apparent size greater than 0.1mm (6.7") behind the Milky Way from photographic surveys in the near infr... M Saito,H Ohtani,A Asonuma,... -...
A value of 4.5 to 5.0 kpc is still preferred in spite of smaller values from surveys in the near-infrared. Finally, I show that as far as structural parameters are concerned, NGC 891, 5033 and 5375 closely resemble the Milky Way Galaxy....

A near galactic-collision between NGC 2207 (left) and IC 2163 (right) spiral galaxies captured by the Hubble Space Telescope in 2007. Scientists predict the Milky Way will collide with our neighbor galaxy Andromeda in about 3 billion years from now. NASA and The Hubble Heritage Team Scientist...
Deep ground-based observations in the near-infrared with NEWFIRM and IRAC observations with the Spitzer Space Telescope were used to conduct a census of the young stellar content associated with each of these clouds. The star formation rates from the stellar census in each of these regions was ...
Could the Milky Way ever become an active galaxy? Is it likely to ever be as luminous as a quasar? Why are quasars generally so much more luminous (why do they put out so much more energy) than active galaxies? Suppose we detect a powerful radio source with a radio telesc...
In part II several different classes of X-ray sources have been introduced, which can be observed within the Milky Way. One of the largest uncertainties in their study is the distance of the more luminous sources, which are often known to not better than a factor of two. This results in...
