Student cleans up archival data and uncovers two stellar cocoons

While investigating 16 years of images of young stars from a retired astronomical camera, Leiden master's student Sam de Regt discovered that two of those stars were still enveloped in birth clouds that had not been seen at this level of detail before. He publishes his data-cleaning method and the new images of the two stars in the journal Astronomy & Astrophysics.
