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.
Astronomers are puzzled by the so-called "dwarf galaxy
problem" (also known as the missing satellites problem), arising from simulations predicting the evolution of the distribution of matter in the universe.
In 1994 they first observed the strung-out stars of the disintegrating Sagittarius dwarf galaxy
. Then, a few years later, the Sloan Digital Sky Survey (SDSS) began mapping very faint stars all across the northern hemisphere sky.
Washington, August 15 ( ANI ): NASA's Chandra X-ray Observatory has found a massive cloud of multimillion-degree gas in a galaxy about 60 million light-years from Earth, which is likely from a collision between a dwarf galaxy
and a much larger galaxy called NGC 1232.
The astronomers' computer simulation reveals that a collision between Andromeda and its companion dwarf galaxy
Ma2 reproduces the rings.
The strange path took the stars very close to the central region of our galaxy, something that led the team to posit these could be the remains from a massive collision with a dwarf galaxy
Gabriel Torrealba (University of Cambridge, UK) and others discovered the dwarf galaxy
in survey data collected at the Very Large Telescope in Chile.
TEHRAN (FNA)- A team of astronomers discovered a tiny and isolated dwarf galaxy
which is almost 7 million light years away from the Milky Way.
Washington, Apr 4 ( ANI ): Despite being a small, or so-called dwarf galaxy
, the Small Magellanic Cloud (SMC) is so bright that it is visible to the unaided eye from the Southern Hemisphere and near the equator.
Within hours, Belokurov replied that he had found yet another Milky Way satellite, a dwarf galaxy
in the constellation Bootes.
According to their theory, if a dwarf galaxy
had an encounter with the halo of our galaxy, the movement of its stars could be a result of Milky Way's gravitational pull.
When Yashar Hezaveh (Stanford University) and others employed the Blue Waters supercomputer to analyze the ALMA ring, they found a dwarf galaxy
hidden within the depths of the background galaxy's distorted image.
