How do we see distant galaxies?
The most distant galaxies are caught up in the expansion of the Universe, causing distant galaxies to redshift past the point where our optical and near-infrared telescopes (like Hubble) could detect them. Finite sizes and observing times meant that only the galaxies above a certain brightness threshold could be seen.
Why are you looking back in time when you view distant galaxies?
The time it takes for light from objects in space to reach Earth means that when we look at planets, stars and galaxies, we’re actually peering back in time. When we look up at the stars, we are looking back in time. The light entering our eyes from these distant objects set off years, decades or millennia earlier.
Can we look back in time?
This ability to look back in time is based on the fact that even light has a speed limit. It bowls along at 186,000 miles per second. So if you look at a star that is 30 light years away, that is what it looked like 30 years ago. The same applies to stars that are millions of light years away.
Do we see the sun in real time?
3 Answers. Yes, you are right. We don’t only see the Sun 8 minutes in the past, we actually see the past of everything in space. The further an object is from us the longer its light takes to reach us since the speed of light is finite and distance in space are really big.
What stage is the Sun’s currently in?
The Sun is currently a main sequence star and will remain so for another 4-5 billion years. It will then expand and cool to become a red giant, after which it will shrink and heat up again to become a white dwarf. The white dwarf star will run out of nuclear fuel and slowly cool down over many billions of years.
