Hey guys! Its been 8 months since i ve started the hobby of astronomy.I would like to dig deeper now,i am looking for a book in astrophysics that involves mostly formulas and mathematics.With so many books in the market its hard to defferentiate science books from just books with information about the subject
This video was published on YouTube in March of this year and describes the development of universe in exponentially growing steps through time. That probably means that it is highly speculative, but it is interesting.
I'm about halfway through at 7 billion trillion trillion trillion years in the future, and quite curious about how it will end.
I've just joined the forums. I came here because I wanted to interact with the people with whom I have something in common, make friends and share knowledge with all of them and learn from them. I hope it could work out well, I have also planned to publish a paper that I am preparing on dark matter that is supposed to be completed 6 months later, I'm currently 15 years and have no good friends of me, so I came here.
So I've been trying to solve this question, which feels really simple, but there's a lot of room allocated for it so something feels wrong.
Q: Stars must have an apparent magnitude equal or greater than +6.0 to be seen by the naked eye, whereas the Hubble Space Telescope can view stars as faint as +30.0. How much fainter are the faintest objects visible to the Hubble Space Telescope relative to the dimmest stars visible to the naked eye?
While im here if someone could check this question as well
Q: If the Sun and the full moon have apparent magnitudes of -26.71 and -12.24 respectively, then how many times brighter is the sun compared to the full moon?
it's not just -26.71--12.24 right,,, something just definitely feels too simple.
Any help is really appreciated <3
Thank you for your time
