Hubble discovers dwarf galaxy in cosmic neighborhood

The cosmic neighbor, the nickname Bedine 1, is a nominal size, a longer galaxy.

It measures approximately 3000 light-years on its largest limit - a fraction of the size of the Milky Way.

The Hubble Space Telescope has unexpectedly discovered a dwarf galaxy in our cosmic backyard, which is located just 30 million light-years away, scientists say

Researchers used the NASA / ESA Hubble Space Telescope to study white dwarf stars within the globular cluster NGC 6752.

According to the European Space Agency (ESA), the purpose of the observation was to use these stars to measure the age of the circular cluster, but in this process, the researchers did an unexpected search.

Royal Astronomical Society: According to a study published in Letter's monthly notice, a compact collection of stars was visible in the outer parts of the field seen with Hubble's advanced camera for the survey.

After careful analysis of its brightness and temperature, astronomers concluded that these stars were not related to the cluster - which is part of the Milky Way - but they are millions of light years away.

The cosmic neighbor, the nickname Bedine 1, is a nominal size, a longer galaxy.

 It measures approximately 3000 light-years on its largest limit - a fraction of the size of the Milky Way.

Not only is this small, but it is also incredibly unconscious, researchers said. 

These qualities led astronomers to classify it as a dwarf globular galaxy.

Dwarf spherical galaxies are defined by their small size, low-brightness, lack of dust and old stellar population. 

This type of 36 galaxies is already known, which are present in the local group of galaxies, of whom 22 are Milky Way's satellite galaxies.

It is located approximately 30 million light-years from the Milky Way and 2 million light-years away from the nearest admirable Big Galaxy Host, NGC 6744. 

This is probably the most different little dwarf galaxy discovered today.

From the properties of their stars, astronomers were able to predict that the galaxy is approximately 13 billion years old - almost as old as the universe.

Due to its alienation - which resulted in a rare interaction with other galaxies - and its age, Benedin 1 is the celestial equivalent of a living fossil from the initial universe.

The discovery of Bedin 1 was really a serious discovery.

 Very few Hubble images allow for viewing such unconscious objects, and they only cover a small area of the sky.

A large area of view of the future telescopes, such as the WFIRST telescope, will be cameras covering a very large area of the sky and they can meet many galactic neighbors.
