M31 is the most remarkable galaxy for those stargazing from the northern hemisphere and can be easily found as a fuzzy patch in binoculars, even under urban skies. At about half a trillion stars, it's larger than the Milky Way and will collide with it in a few billion years. — Jamie ...
[…] By contrast, orbits with larger pericenters do not decay due to dynamical friction. In this case, the MW and M31 continue to evolve in isolation. Based on the best current data, both outcomes are almost equally likely.” “Equally likely” is not an expected outcome when talking...
Not only is it growing larger, but the edge of the universe is expanding at a faster and faster rate. Scientists think that the edge of the universe is expanding faster than the speed of light.What is the universe made of?Even though the Earth seems really big to us, it's actually a...
Massive elliptical galaxies are another type of galaxy, which are much larger than the Milky Way. "They look somewhat spherical, kind of egg-shaped," Samuel said. "Their stars are going to be older, and the galaxy will have stopped forming new stars a long time ago." Elliptical galaxies ...

Female ejaculation is surprisingly more common than you might think, but the exact numbers are tricky to nail down because of how differently people have defined it. Some people define it as: Vaginal lubrication Squirting Coitalincontinence

It's pretty likely that Omega Centauri is the largest globular cluster in the Milky Way. At 10 million stars, it's much bigger than most, which have more like a million stars. Also, it has multiple populations in it and possibly a central black hole. It may be that Omega Centauri is...
the Milky Way Galaxy is not alone in the Universe. In addition to our galaxy being part of theLocal Group– a collection of 54 galaxies and dwarf galaxies – we are also part of the larger formation known as theVirgo Supercluster. So you could say the Milky Way has a lot of neighbors...
The size of the galaxy is measured from the point at which the number of stars in the disk significantly drops, so finding disk stars is key to determining the Milky Way’s size. Coincidentally, disk stars tend to be much younger than the halo stars. Since stars gradually build up ...
