Scientists discover a small galaxy, 30 million light-years away, that could be a "living fossil" from the beginning of the universe
- The newly discovered galaxy was recorded in the globular cluster NGC 6752
- It is estimated to be about 13 billion years old, so it's from the beginning of the universe
- Scientists have discovered this while trying to determine the age of the cluster
Astronomers encountered a previously unseen dwarf galaxy in our "cosmic yard."
Hubble Space Telescope originally determined that it determines the age of the globular cluster by measuring the weakest stars.
But they discovered a small galaxy with a mere 3000 light-years in its widest point.
According to experts, the weak galaxy can be roughly 13 billion years old – so it is almost as old as the universe itself.

Astronomers in our space yard will stumble on a previously unoccupied dwarf galaxy. The team has since then called Bedin 1 (seen in a dense star star)
The newly discovered galaxy was recorded in the globular cluster NGC 6752.
The team has since called Bedin 1.
Spherical dwarf galaxies, such as Bedin 1, are fairly common in the universe – but the new remaining galaxies discovered on the outside of Hubble's Advanced Surveillance Cameras are out of the question.
Although it is estimated to be about 13 billion years old, it seems to have little interaction with other galaxies.
"While dwarf spheroidal galaxies are not unusual, Bedin 1 has some remarkable features," the Hubble team said.

"Not only is it just a few dwarfs that have well-established distance but are also extremely isolated.
"It lies about 30 million light-years from the Milky Way and 2 million light-years from the nearest acceptable host of galaxy NG 6744.
"It's the safest little dwarf galaxy."
According to Hubble's team, Bedin 1 is extremely weak and reaches a maximum of 3,000 light-years.
WHAT IS TELESCOPE HUBBLE SPACE?
The Hubble Telescope was launched on April 24, 1990 via the Discovery Space Shuttle in Florida's Kennedy Space Center.
It is named after the famous astronomer Edwin Hubble, who was born in Missouri in 1889.
He is probably best known when he finds out that the universe is expanding and the speed that is happening now has created the Hubble constant.
Hubble has made more than 1.3 million observations since its mission began in 1990 and helped to publish more than 15,000 scientific papers.
Hubble's telescope is named after Edwin Hubblet, who was responsible for the advent of the Hubble Constant and is one of the greatest astronomers of all time
Earth's orbit runs at a speed of about 17,000 mph in a low orbit about 340 kilometers altitude.
Hubble has a positioning accuracy of .007 seconds, which is like the ability to fire a Franklin D. Roosevelt's laser beam at tenths about 200 miles away.
Hubble's primary mirror is 2.4 meters (7 feet, 10.5 inches) and is 13.3 meters in length – the length of a large school bus.
In the local group of galaxies, there are another 36 known dwarf spherical galaxies and 22 Milky Way satellites.
The newest, however, appears to have existed mostly in isolation from the days of the early universe.
"The discovery of Bedin 1 was a really unfortunate finding," says the Hubble team.
"Very little of Hubble's images allow you to see such weak objects and cover only a small area of the sky."
