The newfound Giant Coma Stream of stars stretches
nearly 1.7 million light years across the cosmos, and it could have holes
blasted through it by clumps of dark matter
The black streak is the newly discovered Giant Coma Stream, which is ten times as long as the Milky Way.
Some astromomers have found the biggest stream of
stars ever recorded. This tendril of stars is extraordinarily faint, but it and
others like it could eventually help us unveil the true nature of secrets
of dark matter.
The stream of stars, called the Giant Coma Stream,
appears to float unmoored from any particular galaxy in the Coma galaxy
cluster, about 300 million light years away from Earth.
