Thoughmost galaxies are rushing away from usas the Universe expands,Andromedaand the Milky Way are orbiting each other and closing in fast. Collisions between galaxies aren’t always catastrophic (the Milky Way is colliding with theCanis Major Dwarf galaxyright now, swallowing its stars up into th...
Now back in the 1920s, the Hooker telescope was the most powerful telescope in the world. 现在,回到十九世纪二十年代,胡克望远镜是世界上最强大的望远镜。 And through it we could see, see for the first time, that the universe extends far, far beyond the Milky Way galaxy. 通过它,我们第一次...
A galaxy is a collection of stars and planets, gas and dust, and dark matter, all held together in a gravitational pull, and orbiting around a central point of gravity. Kind of like our solar system, but on a MUCH larger scale. The concept of a galaxy was first described by the Greek...
It was thought that all the stars in the Universe were in the Milky Way. However, this changed in the 1920s during what is known as the “Great Debate”. Different religions/regions have different views on how the Galaxy came into creation. The term Milky Way comes from Roman/Greek ...
The spiral arms usually have more gas and dust, and they contain most of the newly formed stars, which make them appear blue in color imagery. A spiral galaxy may have a horizontal bar passing through its hub; our own galaxy, the Milky Way, is believed to contain a bar. Elliptical ...
What is the Large Magellanic Cloud an example of? The Large Magellanic Cloud is considered a dwarf galaxy. It was once thought to be a satellite galaxy of the Milky Way, or a very small galaxy that buzzes around our galaxy. Around five dozen satellite galaxies are currently known, but it...
on its way out ofthe Milky Waygalaxy at a speed of three times the orbital speed of the Sun around the Galactic Centre. HE 0437 is not expected to hit our Sun, but it is an example of a star that will eventually become a Rogue Star once it has left the confines of the galaxy. ...
A hypothetical view from Earth as the Andromeda galaxy (on left) is about to collide with part of the Milky Way galaxy. Credit: NASA Our Milky Way galaxy is a cannibal. It has grown by consuming other galaxies. Yet, it too, may be destined to collide and merge with an even bigger ...
It is now known to be part of a stellar stream, a group of objects with very similar velocity vectors that were once part of a dwarf galaxy engulfed by the Milky Way. 8. Aldebaran But intelligent beings living near another red giant — Aldebaran — could be much more optimistic about ...
Let’s talk about that before we move on to some of the newer technologies.Now back in the 1920s, the Hooker telescope was the most powerful telescope in the world.And through it we could see, see for the first time, that the universe extends far, far beyond the Milky Way galaxy.We...
