The astronomers using Hubble space telescope made an unexpected discovery: a group of stars thought of the Milky Way galaxy in a galaxy that was only 30 million light years away in an isolated space.

The international team was investigating a coordinate called NGC 6752, about 13,000 light years away from Milky Way's borders. But after studying bright stars and temperatures, scientists realized that objects were 2,300 times farther before they thought.

"This was really a serendipite found," Luigi "Rolly" Bedin, an astronomer at the Padova Italian Astronomy Observatory, told NBC News MACH email. He is the director of the Bedin group and is the main author of the paper describing the discovery, published on Thursday in the News Monthly magazine of the Royal Astronomical Society.

Newfound galaxy, double bedin, thanks to the recognition of the scientist's discovery, seems to be a minor and annoying appearance of Hubble's force. And it's not surprising: they are 30 times smaller and a thousand times dimmer than the Milky Way.

Unlike the Milky Way, unlike a type of spiral galaxy, Bedin 1 is roughly spherical. Astronomers call them the spheroidal nano galaxy. It is one of the 36 galaxies known to the Local Galaxy Group, including Milky Way and the Andromeda Galaxy in the area.

The Galaxy is estimated to be about 13 million years ago, becoming "from the very beginning of the universe".

The universe itself is believed to be about 13.8 million years ago.

"Jolas Pasachoff, at Williams College Williamstown, Massachusetts Massachusetts astronomer, was not involved in the new investigation, said NBC News MACH's email." Hubble Space Telescope's focus on rice grain issued in arms One, it's very small, it's only an extra object, but this happened this time. "

These findings may not be so weird in the near future. NASA plans to launch the Wide Field Infrared Survey Telescope (WFIRST) in the mid-2020s, and Bedin has already said that it is still in the electronic space development telescope. This view will be 100 times greater than Hubble "You can find many of these Oddballs."
