NASA News 2014: Russia Astronomers Discover Dwarf Galaxy KKs3 Using Hubble Space Telescope Data
The latest scientific discovery has found something close to comic books' "microverse," or miniaturized universe. The National Aeronautics and Space Administration's (NASA) Hubble Space Telescope, along with some astronomers, have discovered a dwarf galaxy -- a universe that is 1,000 times smaller than anything previously found.
The findings were released, late this month, by the Monthly Notices Letter of the Royal Astronomical Society. The discovery was made by a Russian-American team of astronomers in Aug. 2014. Using data from NASA's Hubble Space Telescope, the team of astronomers were not only able to pinpoint the galaxy's location, but they also gave it a name: it has been dubbed KKs3, the "dwarf spheroidal" galaxy.
KKs3 is in the southern sky within the direction of the constellation Hydrus. Besides the Milky Way's discovery, KKs3 has been classified in what some are calling a "Local Group of galaxies" which include the Andromeda Galaxy and dozens of others, Huffington Post reported.
KKs3 is really tiny. According to the astronomers team, KKs3 measures at one ten-thousandth the mass of the Milky Way. It is also the second most isolated dwarf spheroidal galaxy ever seen in the Local Group category.
Of course, finding a galaxy this size was not at all easy. In fact, professor Dmitry Makarov of the Special Astrophysical Observatory in Karachai-Cherkessia, Russia, who is also a member of the Russian-American Astronomy teams, aid via a statement that it is "painstaking work," even with the use of the Hubble Space Telescope.
One of the reasons why the galaxy is so small is the weight of the stars (suns) which are much larger than the Earth's sun. Based on the team's research, they have discovered stars that, weighed together, equal 23 million times more than the Sun, Morning Vertical reported.
While KKs3 has some of the features found in our galaxies, it does not have the necessary raw materials to form its own star, and even leave behind anything older or even remains of stars. The scientists believe that bigger stars like Andromeda are stripping these tiny galaxies of all their raw materials.
It was first perceived that KKs3 was part of a larger galaxy. It was mapped out in August.
The scientists are hopeful in finding similar galaxies like KKs3, but they would need a more powerful telescope like the James Webb Space Telescope and the European Extremely Large Telescope.
KKR25 is the first known isolated dwarf galaxy, and it was found in 1999.
