Why The Discovery Of The Milky Way
Astronomers have discovered a vast galaxy made up almost entirely of dark matter, an unexpected find that could bring us one step closer to understanding what the mysterious Knockoff fashion jewelry bracelet stuff is all about.
Dubbed Dragonfly 44, the collection of stars lies Knockoff hermes leather tote about 330 million light years from Earth in a group of galaxies known as the Coma cluster. It's about the size of our own Milky Way galaxy but Knockoff enamel gold jewelry much, much fainter. It contains only about 1 billion stars, which is roughly 1 percent the number of stars in our galaxy.
The team of astronomers who discovered Dragonfly 44 with the help of Hawaii's W. M. Keck Observatory were completely surprised to find the dark galaxy.
"It is an exciting discovery," said Jeremiah Ostriker, an astrophysicist at Columbia University."It gives us a chance to study [dark matter] in detail close up."
How do we know Dragonfly 44 is made of dark matter if we can't see the stuff?
The greater a galaxy's overall mass, the faster its stars move relative to each other. "It means that Dragonfly 44 has a huge amount of unseen mass."
In other words, oodles of dark matter.
Theory holds that dark matter particles annihilate each other and emit gamma radiation whenever they collide, van Dokkum said. Scientists have been searching for this distinctive signal in dwarf dark galaxies, he added, but the signal would be much stronger in a big dark matter galaxy like Dragonfly 44.
"The race is on to find massive dark galaxies are even closer to us than Dragonfly 44, so we can look for feeble signals that may reveal a dark matter particle," he said imitation white enamel bracelet in the news release.
