They take some tacos and throw them in space and see if they hit another planet.
1 microlensing !
Probably, though most planets discovered so far - or perhaps all of them - are in our own galaxy. The reason for this is simply that it is easier to discover planets when they are relatively close to us. But, having discovered about a thousand planets nearby, there is no particular reason to believe that other galaxies would be devoid of galaxies. After all, the same laws of physics work in other galaxies as here.
None. Galaxies on the other hand do contain planets
Within our solar system, there are 8 planets, and 4 dwarf planets. There are also over 500 dwarf planets from 2 galaxies that have been discovered orbiting other stars.
To know what is the life there, and if there's any other creatures or "aliens". some scientists are looking for planets with water and life on them.
yes we can live
So far most planets are too hot or too cold to support life or are gas giants. Scientists are yet to find signs of life in other planets, other than planet Earth. The universe has many galaxies and planets, most are still yet to be explored. The search for extraterrestrial life is ongoing.
There is not much solid information known about planets in other galaxies. Most planets discovered so far are in our own galaxy. This is because it is easier to discover a relatively near-by planet than one that is much farther away. However, the planets found so far make it likely that in our own Milky Way, and therefore other galaxies as well, have at least as many planets as stars.
Very probably
Galaxies are generally a collection of stars. But within any galaxy, there are lots of other objects, including planets. So galaxies are related to planets in some ways.
There are many other planets in many other galaxies.
Yes. Scientists haven't been able to explore other galaxies. I believe that there is life in other galaxies just like Earth. but how do they explore galaxies? i mean how do they know there are other galaxies? do they have any proof of lik=fe on other galaxies? ^^^^^^^
