M1-92, commonly called Minkowski's Footprint, is a bipolar protoplanetary nebula in the constellation Cygnus. It consists of material expelled by a star transitioning from the asymptotic giant branch toward the planetary-nebula stage, rather than debris from a planet-forming system. Two opposing lob...
IRAS 09371+1212, the Frosty Leo Nebula, is a protoplanetary nebula in Leo distinguished by its unique, crystalline water-ice rich outflow.
Michael Rowan-Robinson is a British astronomer at Imperial College London recognized for his research in infrared and submillimeter astronomy and his models of galaxy formation.
IRAS 22036+5306 is a protoplanetary nebula located in the constellation Cassiopeia. Identified through infrared astronomical surveys, it is characterized by a distinct bipolar outflow. The nebula exhibits point-symmetric structures and high-velocity molecular jets as it transitions from an asymptoti...
IRAS 13208-6020 is a protoplanetary nebula in Centaurus whose Hubble Space Telescope observations revealed intricate, looped structures produced by ongoing mass loss.
IRAS 23304+6147 is a protoplanetary nebula in Cassiopeia notable for displaying the rare 21-micron dust feature, indicating unusual carbon-rich material in its envelope.
IRAS 20068+4051 is a protoplanetary nebula in Cygnus with a bipolar morphology and an asymmetric dust envelope, identified by the IRAS infrared satellite mission.
