It never gets here. Its light took a billion years.
Einstein's cross is located about 8 billion light-years away from Earth. It is a gravitational lensing phenomenon where the light from a distant quasar is bent by the gravitational field of a foreground galaxy, creating multiple images of the quasar.
No. Life cannot exist anywhere near a quasar. For one thing there is no "on" a quasar. A quasar consists of a disk of extremely hot matter falling into a supermassive black hole. What cannot cross the event horizon is ejected in jets at the poles at nearly the speed of light. The radiation of even a moderate quasar is more than 10 trillion times that of the sun. Even light years away any planet would be completely sterilized.
Arcturus is approximately 37 light years away from Earth.
Light travels at a speed of about 186,282 miles per second. Therefore, it would take approximately 8 minutes and 20 seconds for light to travel from Earth to the sun, which is approximately 90 million miles away.
It means it has taken light 130 years to travel the distance. Light travels 5,878,630,000,000 miles in 1 year, so something 130 light years away, is a LONG way away.
10 billion light years was the distance. And we believe it was a quasar.

It could be a star, a galaxy, a quasar.
A quasar is a highly energetic and luminous region at the center of a distant galaxy. It appears as a point-like source of light that can outshine an entire galaxy due to the accretion of material onto a supermassive black hole at its core.
2,880,526,350,000,000 miles.
Our sun is approximately 93,000,000 miles away. One light year isapproximately 5,866,000,000,000 miles away. 93,000,000/5,866,000,000,000 = 0.0000158 light years.
I think that proxima centauri is approximately 4 light years away from the sun. One light year is equal to 5,865,696,000,000 miles. So, 5,865,696,000,000x4 = 23,462,784,000,000 Proxima Centauri is approximately 23,462,748,000,000 miles away from the sun.
Pollux is approximately 33.78 light-years away from Earth, which is equivalent to about 198 trillion miles.
A distant, very small and very bright point of light is likely a star. Stars are celestial objects that emit light and are located at vast distances in space.
A distance of 40 light years is approximately 377 trillion kilometers or 235 trillion miles away.
One light year away is equal to: 9,461,000,000,000 kilometers 9,461,000,000,000,000 meters 5,879,000,000,000 miles
