According to wiki:
It is extremely difficult to define the age at which the Milky Way formed, but the age of the oldest star in the Galaxy yet discovered is estimated to be about 13.2 billion years, nearly as old as the Universe itself. This estimate is based on research by a team of astronomers in 2004 using the UV-Visual Echelle Spectrograph of the Very Large Telescope to measure, for the first time, the beryllium content of two stars in globular cluster NGC 6397. From this research, the elapsed time between the rise of the first generation of stars in the entire Galaxy and the first generation of stars in the cluster was deduced to be 200 million to 300 million years. By including the estimated age of the stars in the globular cluster (13.4 ± 0.8 billion years), they estimated the age of the oldest stars in the Milky Way at 13.6 ± 0.8 billion years. Based upon this emerging science, the Galactic thin disk is estimated to have been formed between 6.5 and 10.1 billion years ago.
It is very difficult to define the age of the Milky Way as it is constantly changing.
However, the oldest star so far found in our Galaxy is about 13.2 billion years, nearly as old as the Universe itself.
The oldest galaxy so far found - within the observable Universe - is about 13.2 billion years old. (At present it is not named)
This would have formed about 750 million years after the big bang,
It's very difficult to answer this question as spiral galaxies have different ages.
The Milky Way Galaxy - our galaxy - is approximately 13.2 billion years old, nearly as old as the Universe as a star HE 1523-0901, was estimated to be about that old.
It's a bit like asking how old is a human.
about 20 billion years old
Firmadon the universe is only 13.7 billion years old.
Galaxies range in age however they're billion/s of years old.
elliptical galaxies seem to have stopped making new stars more than 10 billion years ago
I would say about 500 million light years
The size of a galaxy means how old the galaxy really is and also the stars indicate how old the galaxy is. So both the size nd the amount of stars indicate how old the galaxy is.
No one really know how old our galaxy is, but most scientists belive it is billions years old. Personally, I don't belive that our galaxy is billions of years old. I belive that the galaxy was created when the earth was created. So, I think that the out galaxy is only about 2,000 years old or so.
Kaokor Galaxy is 52 years old (birthdate: May 15, 1959).
about 14 billion years old
Yes, it is old.
An elliptical galaxy
Elliptical Galaxy The Elliptical Galaxy has mostly old stars and blue stars are new stars.
Pick anyone - they are all old.Our Milky Way Galaxy is believed to be about 13.2 billion years old
sombrero galaxy is 10 to 13 billion years old
the name of the galaxy was callled chocolate caramel
48 year old
The "real" answer is a protogalaxy or primeaval galaxy as these are the first stages in the formation of a galaxy.However, it's more than likely, the question has to do with new star formation, in which case, it will be a spiral galaxy (but the galaxy is not young) Our galaxy - the Milky Way - is about 13.2 billion years old - almost as old as the Universe itself.
