Astronomers have discovered what may be the oldest and most distant galaxy ever observed. The galaxy, called HD1, dates from a bit more than 300 million years after the Big Bang that marked the origin of the universe some 13.8 billion years ago, researchers said on Thursday.

What is older than the universe?
Far from being 13.8 billion years old, as estimated by the European Planck space telescope’s detailed measurements of cosmic radiation in 2013, the universe may be as young as 11.4 billion years. If that is, indeed, the case, then Methuselah is one again older than the universe.
What is the youngest thing in the universe?
GN-z11 is the youngest and most distant galaxy scientists have observed. This video zooms to its location, some 32 billion light-years away.
What is the oldest thing ever on Earth?
Microscopic grains of dead stars are the oldest known material on the planet — older than the moon, Earth and the solar system itself. By examining chemical clues in a meteorite’s mineral dust, researchers have determined the most ancient grains are 7 billion years old — about half as old as the universe.
What was there before the universe?
In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today.
What’s the oldest star we can see?
HD 140283 (also known as the Methuselah star) is a metal-poor subgiant star about 190 light years away from the Earth in the constellation Libra, near the boundary with Ophiuchus in the Milky Way Galaxy. Its apparent magnitude is 7.205. It is one of the oldest stars known.
What’s the farthest thing we’ve seen in space?
Cambridge, MA — An international team of astronomers, including researchers at the Center for Astrophysics | Harvard & Smithsonian, has spotted the most distant astronomical object ever: a galaxy.
What is the oldest galaxy known to man?
Poring over some of the earliest science observations the telescope took, they found a galaxy that stood out from the rest. Named GLASS-z13, this appears to be the oldest galaxy we’ve ever seen. GLASS-z13 in JWST NIRCam (Naidu et al. 2022).
What’s the farthest galaxy we can see?
Researchers have spotted what might be the farthest astronomical object ever found — a galaxy candidate named HD1 that they estimate is 13.5 billion light-years away. That’s an astonishing 100 million light-years more distant than the current farthest galaxy, GN-z11.
Which is first language in world?
Dating back to at least 3500 BC, the oldest proof of written Sumerian was found in today’s Iraq, on an artifact known as the Kish Tablet. Thus, given this evidence, Sumerian can also be considered the first language in the world.
How old is the oldest water?
1.6 billion years
The world’s oldest known water has been discovered by researchers in Canada. A 17-year search of Ontario’s Kidd Creek Mine uncovered liquid that has been trapped between rocks for 1.6 billion years, according to the team at the University of Toronto.
How was Earth created?
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
Who created the universe?
Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
When did time begin?
approximately 14 billion years ago
According to the standard big bang model of cosmology, time began together with the universe in a singularity approximately 14 billion years ago.
Can something be created from nothing?
So particle-antiparticle pairs can be created from “nothing”, that is from no particles to two particles, but energy must be provided, so these particles can be viewed as having been created from the energy.
What’s bigger than the universe?
No, the universe contains all solar systems, and galaxies. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy, and the universe is made up of all the galaxies – billions of them.
How much life is left in our Sun?
So our Sun is about halfway through its life. But don’t worry. It still has about 5,000,000,000—five billion—years to go. When those five billion years are up, the Sun will become a red giant.
How old is the youngest star?
Age and distance
| Title | Object | Data |
|---|---|---|
| Oldest star | HD 140283 | 14.5±0.8 billion years |
| Youngest | Stars are being formed constantly in the universe so it is impossible to tell which star is the youngest. For information on the properties of newly formed stars, see Protostar, Young stellar object and Star formation. |
Is the space infinite?
There’s a limit to how much of the universe we can see. The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
How many Earth years is a Lightyear?
Coe et al. For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year.
How long would it take to travel 13 billion light-years?
At the speed of light, the fastest speed we know, it’ll take 13.3 billion years.
