Participants of an online astronomy project have found mysterious objects in our Milky Way.
Volunteers of the milky way project (http://www.milkywayproject.org/) where asked to scan thousands of images from the Spitzer Space Telescope. People started chatting about strange looking yellow balls that kept reappearing in some of the images. This caught the attention of astronomers working on the project.
The yellow balls appear to be several hundreds to thousands of times the size of our solar system. Researchers think they might be a missing link in the life cycle of stars. This new phase would fit in between the embryonic phase and the newborn phase.
In reality the objects aren't actually yellow but they appear as such in the processed infrared images of the Spitzer Space Telescope
