#club75 || How do we see the past in space??!!!

Let's start with the sun first. The first light we see in the sun every morning is the light 6 minutes before the sun reached the earth just then. Suppose for some reason the sun is destroyed, then we will see the sun in the sky for the next 8 minutes, then we will not see the sun again. So the sun we saw in the sky for those 8 minutes is the sun of the past 6 minutes ago.

The nearest star to the Sun, named Proxima Centauri, is 4.1 / 2 light-years away. It has been calculated that if you travel from Earth to the Sun 2 lakh 72 thousand times, you have to travel as much as you have to travel to reach that star. This means that the light of this star that we see sitting on the earth is the light of two light-years past four decimal one. If that star is destroyed, we will see that it is exactly four decimal one-two light-years. But the funny thing is that the star we have seen so far is passed, in fact, the star has disappeared long ago.

The Andromeda (M-31), a neighboring galaxy of our Milky Way galaxy, is also visible to the naked eye. That means you're seeing something from 2.3 million years ago now. There are so many fragments in space that it takes thousands, millions, millions, billions of years for light to reach the earth. The famous Orion Nebula (M-42) is located in the middle of the waist belt of the Orion constellation (Adam Surat). It can be seen with the naked eye even though it is like a dazzling light.

Scientists have recently discovered a galaxy using the Hubble Space Telescope, and it has been calculated that this galaxy contains light that began its journey before the creation of our solar system. This means that the light of that galaxy has not yet reached our earth.

And the galaxy that scientists have recently discovered is the oldest galaxy ever discovered. Scientists have used data from the Hubble Space Telescope and the Cake-1 telescope to discover this galaxy. Name of this galaxy (z8_GND_5296). This means that scientists have reached the time closest to the Big Bang by discovering this galaxy. And we will never see this galaxy. Of course, this is not the last frontier of space, and its final boundary is still unknown. So whatever we see in space, nothing is present, everything is past.
