Out of curiosity, are there any potential exoplanets which align with ufo style claims? Eg around the plaeides cluster. (Just gor fun speculation sake) And what do you think the chances are of imagery of exoplanets using the JWST?

Yes. I look forward to launching JWST

Why does earth rotate on its axis? Do all planets rotate like that (faster or slower) or are there planets that don't rotate at all?

From what I know I believe the planets all the planets spin. Even when we see only the same side of the face of the moon, it is in rotation, but its orbital period is equal to its period of rotation, so we have the impression that it does not rotate. This also happens with planets that are very close to your star. more

Even we've talked about it in school I still don't quite understand why the lifespan of larger stars is shorter than that of smaller stars. Could you maybe explain it to me? Thanks in advance.

The stars remain stable throughout their life due to hydrostatic equilibrium (nuclear fusion vs. gravity). The larger the mass of a star, the faster it will burn its fuel, to counterbalance the pressure of gravity. That way your fuel ends up astronomically fast. While smaller stars live for billions of years. Red dwarfs live for trillions of years.

Why do people say you can travel through time in a worm hole theoretically?

Meteor Shower Time: The Geminids!

The biggest rival of the Perseid meteor shower has arrived! The Geminids which has a reputation for the enormous about of meteors it produces peaks Friday the 14th. This shower often gets overlooked due to the fact that much of the Northern Hemisphere is freezing its buns off during this time. But if you are somewhere warm… or even have a decent sized window, you will want to give this one a shot.

What is cosmic radiation, is it everywhere? If not, how are they created?

I did not understand. Cosmic microwave background or cosmic ray?
