What is the Biggest thing in Milky Way?

Answer 1

We can't be sure, but it is likely that the oldest things in the universe are brown dwarf stars. The bigger a star is, the faster it ages and to sooner it will explode, but brown dwarf stars can last for the lifetime of the universe itself.

Our universe is, we believe, somewhere around 14 billion years old, and it seems unlikely that any stars could have formed for the first several million years. So the oldest stars still in existence are probably about 13.5 billion years old, and essentially unchanged since then.

Answer 2

The oldest thing in the Milky Way is most likely an stars that are near the end of their lives or any extremly large objects that move so slowly that when they first appeared here they were unable to be moved out of the Milky Way.

Answer 3

That's a tough one!

The galaxy has the unglamorous name of UDFy-38135539, the team of European researchers said.

"Here we report the detection of ... photons emitted less than 600 million years after the Big Bang," they wrote.

Light travels at a speed of 186,000 miles a second, or about 6 trillion miles (10 trillion km) a year. Astronomers can use light-speed as a kind of time machine, and seeing light emitted from objects very far away shows them as they were in the past.

In this case, the galaxy's light first started traveling 13 billion years ago, right after the Big Bang.

The distance is measured using what is called red shift, a kind of Doppler effect of light. Just as a train's whistle seems to change in pitch as the train approaches and passes, light's color also shifts.

This galaxy has a red shift of 8.55, making it the farthest and oldest ever seen.

At this time in the early universe, a haze of hydrogen gas was everywhere, but radiation from primeval galaxies was causing a process called ionization that changed the nature of the hydrogen.

Answer 4

There are possibly many answers to this question.

There is a giant black hole in the centre of the Milky Way of about 3.6 million solar masses.

The Gum Nebula is about 1,100 ly across.

Omega Centauri is the largest globular cluster with a diameter of about 150 light-years.

VY Canis Majoris is a red hyper-giant star and is among the largest known stars in our galaxy with a radius about 2,000 times the radius of the Sun

Answer 5

We don't know; we hardly know details on even relatively close galaxies, and the ones REALLY far away are specks of light in even our biggest telescopes.

Answer 6

Basically that's the cosmic microwave background radiation.
