Only, only from the Light that is being sent from there to here. The only reason that we know so much (temperature, mass, age) is that this Light comes in many types - Gamma, X-Ray, UV, visible, IR, radio, ... each has its own unique story ... to tell.
The oldest planetary systems in the Milky Way Galaxy are believed to have formed around Population II stars, which are older and have lower metallicity compared to younger stars like our Sun. These early planetary systems likely contain rocky planets similar to Earth.
We do not know. Although we have detected planets in other solar systems, we do not know what colors they are.
Truest answer is we don't know. Extra solar planetary science is still in its infancy. There have been several super Earths discovered in other systems, but it is not certain for those planets support life, of it they would be habitable by humans. What we do know is that we do not have the technology yet to reach them even if they could support human life.
Inside a cold nebula, gravity will cause gas and dust to clump together, eventually forming new stars and planetary systems. These regions are conducive to star formation due to the collapse of dense pockets of gas and dust under their own gravity. As the newly formed stars continue to evolve, they may also create planetary systems with orbiting planets and other celestial bodies.
thats hard to know! a lot thats all you need to know

Our solar system is called the "Solar System." It consists of the Sun and all the objects that orbit around it, including planets, moons, asteroids, and comets. Compared to other planetary systems in the universe, our Solar System is unique in its arrangement and composition, but there are many other planetary systems out there with their own set of planets and celestial bodies.

Any other solar systems in our neighborhood of space would still be 10-50 light years away - simply too far to do anything more than specialty astronomy that allows us to infer whether there are planetary bodies circling the stars within that distance range. That's about the best we can do.
Some astronomers are likely to be good at DIY, but most would probably get a contractor in.
Astronomers know because they have studied star patterns and placements and know when there has been a change between where there is a black hole and where there isn't one.
They dont

to see stars and planets and other stuff in space... IDK im guessing, someone answer, i needa know plzzz
No. There are almost no astronomers that think Pluto is a planet. They know it's officially a dwarf planet.
By their gravitational effects.
