A New Paper All About #yellowballs

PIA18909_fig1

There is a new Milky Way Project paper in the news today, concerning the #yellowballs that were found by Milky Way Project volunteers.

The Yellowballs appeared on the very first day of the Milky Way Project when user kirbyfood asked ‘what is this?’ and I wasn’t sure so jokingly called it a ‘#yellowball’, since that’s what is looked like. We use hashtags on talk.milkywayprojct.org, and that user, and many others, went off and tagged hundreds of the things over the next few months. Before we knew it there was a catalogue of nearly 1,000 of them. However, we still didn’t know what they really were, and so Grace Wolf-Chase, Charles Kerton, and other MWP collaborators have put a lot of effort into figuring it out. From the JPL press release:

So far, the volunteers have identified more than 900 of these compact yellow features. The next step for the researchers is to look at their distribution. Many appear to be lining the rims of the bubbles, a clue that perhaps the massive stars are triggering the birth of new stars as they blow the bubbles, a phenomenon known as triggered star formation. If the effect is real, the researchers should find that the yellow balls statistically appear more often with bubble walls.

This new paper is the fourth from the Milky Way Project, and adds to the Zooniverse’s growing list of 80+ publications made possible thanks to our amazing volunteers. You can see the complete set at zooniverse.org/publications.

The full list of volutneers who helped tag the yellowballs is shown below. Each and everyone one of you made a valuable contribution to this paper. Thank you to everyone who helped in this search!

    Another paper for the Milky Way Project. The Yellowballs began on the very first day of the Milky Way Project when a user asked me ‘what is this?’ and I wasn’t sure so jokingly called it a ‘#yellowball’, since that’s what is looked like. We use hashtags on talk.milkywayprojct.org, and that user, and a few others, went off and tagged hundreds of the things over the next few months. Before we knew it there was a catalogue of them.
