This disk is warped and has lots of clumpy dense regions, which may hint towards a past close encounter with the Andromeda galaxy. M33 has an extended neutral hydrogen gas disk which is larger than the optical galaxy as it extends further than the stars. "We now know a lot about where the gas is around M33 and what it looks like. However, they were not able to identify any stars associated with these clouds. They also found out that many previously detected clouds are actually part of the low neutral hydrogen disk of M33. The team managed to detect 11 new clouds. This meant we had to study each cloud in a lot of detail to work out if it was associated with M33," Keenan told. What was more difficult was working out whether the clouds were part of the disk of M33, near M33 but unattached, or whether they were, in fact, related to our Milky Way galaxy. "It wasn't too difficult to detect clouds around M33. Due to the proximity of M33 and the high quality of AGES data, the team could easily detect new clouds around this galaxy. Investigating this area, they were searching for any hydrogen clouds that could be starless dwarf satellites of the galaxy. The scientists have analyzed the data from AGES to look at the neutral hydrogen distribution around M33. AGES is a neutral atomic hydrogen survey aimed at searching for galaxies in different areas of the local universe. The researchers used a set of data provided by the Arecibo Galaxy Environment Survey (AGES) that utilizes the Arecibo Telescope in Puerto Rico. The detection was made by a team of astronomers led by Olivia C.
