O. ur Sun sits in a typical region of the Milky Way Galaxy.. Our nearest neighbor, Proxima Centauri, lies 4.2 light-years away. The average stellar density here in the galactic disk is one star ...
The Centauri system shows that the average distance between stars across the galaxy doesn't paint a full picture of star distribution, which also changes over time.
Two of the stars are among the fastest objects of their kind ever observed in the galaxy, including one that has the highest constant velocity. The star J0927-6335 is moving at a whopping 2,285 ...
On average stars in spiral galaxies tend to be much younger than those in ellipticals. ... over 250 million stars in our galaxy's bulge have been surveyed in near-ultraviolet, optical, ...
In some regions of the galaxy, star formation has proceeded more vigorously than in other regions, and in these more vigorous regions, more generations of stars have formed. Thus, the average ...
Astronomers have discovered more than 200 distant variable stars known as RR Lyrae stars in the Milky Way’s stellar halo. The most distant of these stars is more than a million light years from Earth, ...
And this leads to the more general—and, in my opinion, more awe-inspiring—result of the survey: looking at so many stars, they found that the average number of planets per star in their sample ...
Using the sharp-eyed NASA Hubble Space Telescope, astronomers have for the first time precisely measured the rotation rate of a galaxy based on the clock-like movement of its stars. According to ...
