comment Could mirrors be replaced with CCDs?
The math and physics of how and why mirrors and lenses work is actually pretty advanced stuff - MUCH harder to explain than to use. On the flip side, in the radio bands, astronomers have to do all the math that the lenses and mirrors do pretty much for free. The universe is a weird place.

comment Could mirrors be replaced with CCDs?
There's a lot more to astronomy observations than just recording photons. For example, look at prisms, grisms, gratings, and filters. A CCD just records photons, without noting the wavelength.

This question is too old to migrate. Just so you know.

comment Could the sun burn a human floating next to it?
You need to clarify what you mean by "burn". In this context it could mean different things. One meaning refers to sunburn - damage to the skin caused by too much UV radiation. On refers to combustion - when self sustaining exothermic chemical reaction occur (on Earth, there's usually oxygen involved). Or did you mean something else? Please be clear and specific.

comment How can a low-mass star increase its mass to 1.4 Msun?
@FJC For questions that are on-topic on two sites, the user gets to pick. By accepting the answer on Physics, they have de-facto picked that site.

comment 3000th Question: What does the future of astronomy look like with the next generation of telescopes?
Hi Dean. While it's an interesting question, it's just way too broad in scope for Stack Exchange. It would be a good chat topic but unfortunately, we do not, as yet, have a meaningful activity level in our chat room.

comment What planets and moons have we seeded with life (if any)?
The question would seem to imply that "seeding" is sufficient, even if the body in question contains no medium in which any terrestrial life could possibly grow. Or am I missing something?

comment Does planets revolves around all the 88 constellations?
Planets (for the most part) revolve around individual suns. A constellation is just a group of stars that are in the same part of the sky - as viewed from Earth. So the question, as written, really just doesn't make any sense.
