The Milky Way is part of a collection of galaxies called the Local Group. We’re on a collision course with the most massive and largest member of that collection, which is the Andromeda Galaxy (also known as M31). The Milky Way is the second-largest galaxy, and the Triangulum Galaxy (...
The Milky Way is called the Milky Way because it looks like a milky road or river in the night sky. The way some things are named is truly amazing. In one of our previous articles, we talked about the reason that theoutput power of machines is measured in ‘horsepower‘. Now, it’s...
The solarsystem is located in the sun's neighborhood of stars that i in our Milky Way Galaxy.You will find that the Milky Way Galaxy is in the Virgo Super Cluster.About 4.6 billion years ago, way after the Big Bang happened and started to creategases and stars, the solar system began ...
Our galaxy, the Milky Way, is shaped like a flat disk surrounding a central bulge. Whereas Population I stars are found mainly in the galactic disk, Population II stars mostly reside in the central bulge of the galaxy and in the halo surrounding this bulge.Population II stars date to the ...
exchange gas and dust, but don’t actually collide.Many astronomers believe that the trail of gas and dust that stretches from our Milky Way Galaxy to one nearby is the result of an interaction when the gravitational forces of the Milky Way pulled some dust and gas off the other galaxy. ...
The black hole at the center of the Milky Way, called Sag A*, is much less active than those at the center of other galaxies. A new study points to a simple answer: heat.Spotts, Peter N
This would be an example of our human-centered biases. Although many of them do resemble the Milky Way, others come in wildly different shapes and forms. You've probably seen illustrations of our home galaxy hanging on the walls in countless science classrooms. But we bet you didn't know ...
“We can see that these stars wobble and move up and down at different speeds. When the dwarf galaxy Sagittarius passed the Milky Way, it created wave motions in our galaxy, a little bit like when a stone is dropped into a pond”, Paul McMillan, the astronomy researcher at Lund Observato...
humbling and powerful experiences we have as humans; it is a sight that has inspired us for tens of thousands of years. While the naked eye canseefewer than 4,500 stars at any given point on Earth, we know that there are at least 100 billion stars in the Milky Way (our galaxy) ...
9 The problem to be solved is even broader than this. Sir Martin Rees, Britain's Astronomer Royal, presents "just six numbers" that he argues are necessary for our emergence from the Big Bang. A minuscule change in any one of these numbers would have made the universe and life, as we...
