Your question: What is the farthest and oldest object in the universe?

Universe’s oldest known quasar discovered 13 billion light-years away. Astronomers have found the farthest known source of radio emissions in the universe: a galaxy-swallowing supermassive black hole. … Quasars are some of the oldest, most distant, most massive and brightest objects in the universe.

What is the oldest object in the universe?

With a redshift of z = 8.2, at the time of observation, the burst was the most distant known object of any kind with a spectroscopic redshift. GRB 090423 was also the oldest known object in the Universe, apart from the methuselah star. As the light from the burst took approximately 13 billion years to reach Earth.

What is the farthest thing from the earth?

MACS0647-JD is the farthest known galaxy from the Earth based on the photometric redshift. It has a redshift of about z = 10.7, equivalent to a light travel distance of 13.26 billion light-years (4 billion parsecs).

What is older than the universe?

A constant of 67.74 km per second per megaparsec would lead to an age of 13.8 billion years, whereas one of 73, or even as high as 77 as some studies have shown, would indicate a universe age no greater than 12.7 billion years. It’s a mismatch that suggests, once again, that HD 140283 is older than the universe.

What is hottest thing in the universe?

The dead star at the center of the Red Spider Nebula has a surface temperature of 250,000 degrees F, which is 25 times the temperature of the Sun’s surface. This white dwarf may, indeed, be the hottest object in the universe.

Which is the most dangerous thing in the universe?

Supermassive black holes are strange. The biggest black hole discovered so far weighs in at 40 billion times the mass of the Sun, or 20 times the size of the solar system. Whereas the outer planets in our solar system orbit once in 250 years, this much more massive object spins once every three months.

How far away is Voyager 2 now?

Voyager 2 has been traveling through space for 43 years, and is now more than 11 billion miles from Earth.

What has Voyager 1 found?

Voyager 1 is the first human-made object to venture into interstellar space. Voyager 1 discovered a thin ring around Jupiter and two new Jovian moons: Thebe and Metis. At Saturn, Voyager 1 found five new moons and a new ring called the G-ring.

How long would it take to travel 13 billion light-years?

At the rate of 17.3 km/sec (the rate Voyager is traveling away from the Sun), it would take around 225,000,000,000,000 years to reach this distance. At the speed of light, it would take 13 billion years!

How old is the youngest star?

It’s the youngest neutron star ever discovered: 33 years old.

What is the oldest star in our galaxy?

There is no question that the Methuselah star is old – indeed it is the oldest star in the universe for which there is a fairly precise estimate of its age.

How long before our sun dies?

Our sun’s death is a long way off — about 4.5 billion years, give or take — but someday it’s going to happen, and what then for our solar system?

At what temperature will humans die?

44 °C (111.2 °F) or more – Almost certainly death will occur; however, people have been known to survive up to 46.5 °C (115.7 °F). 43 °C (109.4 °F) – Normally death, or there may be serious brain damage, continuous convulsions and shock.

Is Lava The hottest thing on earth?

Lava is the hottest natural thing on Earth. It comes from the Earth’s mantle or crust. The layer closer to the surface is mostly liquid, spiking to an astounding 12,000 degrees and occasionally seeping out to create lava flows.

What is the hottest color of fire?

When all flame colors combine, the color is white-blue which is the hottest. Most fires are the result of a chemical reaction between a fuel and oxygen called combustion.
