This mass was consistent with a count of about 90 and 70 globular clusters observed around Dragonfly 44 in two different studies.

[5] The most recent work found 20 globular clusters around the galaxy, which is consistent with the current mass measurement.

[6][7] The lack of X-ray emission from the galaxy and its surroundings also shows that the number of globular clusters cannot be as many as was claimed before.

[10] To determine the amount of dark matter in this galaxy, in 2016, astronomers used the DEIMOS instrument installed on Keck II to measure the velocities of stars for 33.5 hours for six nights so they could determine the galaxy's mass.

[11] Following this observation, in August 2016, astronomers reported that this galaxy might be made almost entirely of dark matter.
