Evidence for such tiny clumps of dark matter has not been found yet; observers have only studied much bigger systems, namely galaxies like our own Milky Way, containing gas and stars as their inner core, which is surrounded by a halo of dark matter.

Has dark matter been detected?

“Dark matter accounts for around 85% of all the universe's mass but we have not been able to detect it so far – despite building more and more powerful detectors,” said physicist Professor Chamkaur Ghag of University College London.

Has NASA found dark matter?

When astronomers using NASA's Hubble Space Telescope uncovered an oddball galaxy that looks like it doesn't have much dark matter, some thought the finding was hard to believe and looked for a simpler explanation. Dark matter, after all, is the invisible glue that makes up the bulk of the universe's contents.
