139:. Phase 3 aims to create a reliable bubble catalog (DR2) with the data from phase 2+3 (4.4 million classifications), an improved yellowball catalog and the largest bowshock catalog to date. For this goal the 24 μm part of the image is important: Bubbles are more easy to spot and bowshocks are most of the time visible at this wavelength.

The Milky Way
Project works with data taken from the Multiband Imaging Photometer for Spitzer Galactic Plane Survey (MIPSGAL) and Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE). Only a small part uses WISE data. The project looks for bubbles, which can mean the formation of stars.

The second Data
Release was published in 2019, which contains 2,600 infrared (IR) bubbles and 599 candidate IR bow shock candidates. With a subset of highly reliable subset of 1394 IR bubbles and 453 bow shocks. The lower number of bubbles is being explained with a better quality of the catalog. The
