Using NASA's SPHEREx space telescope, astronomers have observed remnants of the eruption of Nova Persei 1901. As a result, they detected a bipolar molecular hydrogen shell around this nova, which may be a large planetary nebula. The finding was detailed in a paper published March 13 on the arXiv pre-print server.
