The collection of stars at the edge of the area was analyzed and deemed that they were not part of the cluster contained in the Milky Way, but a small galaxy which is nearly 30 million light-years away.
The newly discovered star system, called Bedin 1, in recognition of the scientist's emerging part in its invention, looks weeny and weak even under the powerful Hubble magnification.
The medium-sized, elongated galaxy measures approximately 3,000 light years at its widest, barely 1/30th of the diameter of the Milky Way.
Donald Trump: Chant 'Finish the Wall' Instead of 'Build the Wall'
The wall is part of a larger border security package requested by experts at the Department of Homeland Security. Asked if he expects the move to be challenged in courts, he said "well, we have very strong legal standing".
The different wavelength observations allow viewers to examine the galaxy's structure, discerning between older and younger stars, and spot features, such black holes and nebulas.

They're also fairly common in our Local Group of galaxies - we know of 36 galaxies of this type and 22 of them are in orbit around our galaxy! Scientists were studying the globular cluster NGC 6752 and made an 'unexpected discovery, ' writes the press release on Hubble Space Telescope. The researchers suspect that Bedin-1 is the most isolated galaxy ever discovered. NASA likens it to the "astronomical equivalent of a living fossil from the early universe". Perhaps the most isolated small dwarf galaxy discovered so far, the Bedin 1 is located 30 million light-years away from the Milky Way galaxy and two million light-years from NGC 6744, its nearest plausible galaxy host. Future telescopes with a large field of view, such as the WFIRST telescope, will have cameras covering a much larger area of the sky and may find many more of these galactic neighbours.
Today, September 9, 2009, NASA released the first images taken with the Hubble Space Telescope since its fix in the spring.
