How far away is GRB 090423?

13 billion light-years
On April 23, 2009 the Swift satellite detected a gamma ray burst and as we reported back in April, scientists soon realized that it was more than 13 billion light-years from Earth. GRB 090423 occurred 630 million years after the Big Bang, when the Universe was only four percent of its current age of 13.7 billion years.

What is the oldest thing we can see in the universe?

In 2000, scientists looked to date what they thought was the oldest star in the universe. They made observations via the European Space Agency’s (ESA) Hipparcos satellite and estimated that HD140283 — or Methuselah as it’s commonly known — was a staggering 16 billion years old.

What is the most distant object in the universe?

Astronomers have measured the distance to the farthest cosmic object known to humankind: a galaxy that lies 13.1 billion light-years away. Imaged last year by Hubble’s new Wide Field Camera 3, the galaxy takes researchers back to a mere 600 million years after the big bang.

Is there anything older than the universe?

The star HD 140283 is a subgiant star with an estimated age of 14.46 billion years. That might raise an eyebrow or two for those of you who remember that the age of the universe is estimated as 13.77 billion years.

What is the oldest celestial body?

The oldest celestial bodies discovered thus far have been 13.2 billion years old. Keller and his team used the SkyMapper telescope to find ancient stars as part of an ongoing project to produce the first digital map of the southern sky.

What is the oldest thing in the galaxy?

GN-z11
The oldest known galaxy in existence remains GN-z11, which formed around 400 million years after the Big Bang, as previously reported by Live Science’s sister site Space.com.

How did we find the afterglow of GRB 090423?

The faint infrared afterglow of GRB 090423 was recovered by large ground telescopes within minutes of being discovered. The afterglow is circled in the above picture taken by the large Gemini North Telescope in Hawaii, USA .

What is GRB 090423?

GRB 090423 occurred 630 million years after the Big Bang, when the Universe was only four percent of its current age of 13.7 billion years.

What does GRB 090423 tell us about the universe?

Surely, GRB 090423 provides unique data from a relatively unexplored epoch in our universe and a distant beacon from which the intervening universe can be studied. NASA Official: Phillip Newman Specific rights apply.
