All the stars in the night sky, including our Sun, are just some of the residents of this galaxy, along with millions of other stars too faint to be seen. When masses gather in high enough concentrations, they can bend the light of other objects. The Milky Way is on a collision course with the most massive member of the group, called M31 or the Andromeda Galaxy. From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within. We are not anywhere near the center — The numbers are pretty astounding. To convert to absolute distances, we ideally need to measure the distance to a nearby Cepheid with another, more direct, method. The Milky Way as a whole is moving at a velocity of approximately 600 km per second with respect to extragalactic frames of reference.

The numbers are pretty astounding. The term Milky Way is a translation of the Latin via lactea, from the Greek γαλαξίας κύκλος (galaxías kýklos, "milky circle"). If Voyager were to travel to the center of our Galaxy, it would take more than 450,000,000 years to travel the 8 kpc. Shapley's first estimate of the radius of the Milky Way was off by a factor of 2, but he made an important first step in understanding the nature of our Galaxy.

Casting a pair of binoculars or a telescope across it shows a mix of lighter areas and darker areas; the darker areas are dust that obscures any light from stars, galaxies and other bright objects behind it.

Here’s an article about the “the Milky Way’s overall age at 13.5 billion years old — just two million years younger than the rest of the universe” – you probably mean “two HUNDRED million years” right?Just remember that you’re standing on a planet that’s evolvingThe sun and you and me and all the stars that we can seeWe’re thirty thousand light years from galactic central pointThe universe itself keeps on expanding and expandingSo remember, when you’re feeling very small and insecureIn this week's questions show, I consider what the benefits might be to humanity if we discover that we aren't alone in the Universe. The oldest stars in the Milky Way are nearly as old as the Universe itself and thus probably formed shortly after the Dark Ages of the Big Bang. Because some of these galaxies are prominent in our sky, the names tend to be familiar. NASA estimates the galaxy at 100,000 light-years across. Several more modern methods have been used to map our Galaxy more accurately. But we do know that our Milky Way has a spiral nature from observations made from within our Galaxy (though whether or not it is a barred spiral is still being debated). Diameter of Milky Way in scaled km: 29. If it could travel at the At 17.3 km/s, it would take Voyager over1,700,000,000 years to traverse the entire length of the Milky Way. The constellation Based on observing globular clusters (star clusters) in the galaxy, astronomers have estimated the Milky Way’s overall age at 13.5 billion years old — just 200 million years younger than the rest of the universe.However, scientists are beginning to think that different parts of the galaxy formed at different times. RR Lyrae stars are similar to Cepheid Variables. )We have written many articles about the Milky Way for Universe Today.
