CTA1 is a very dim supernova remnant located within the constellation Cassiopeia, approximately 4600 light-years away. This celestial object has garnered substantial attention from astronomers due to its complex structure and puzzling characteristics.A point source within CTA1 was presumed to be a pulsar. However, despite these expectations, no radio pulses were ever detected. This was until NASA's Fermi Space Telescope uncovered that it pulses at gamma-ray energies. This peculiar source marks the inaugural discovery of a unique class, named "dark pulsars" (rotating neutron stars that exclusively emit pulses in the form of high-energy radiations). These dark pulsars might elude detection in radio or visible light if their emissions are confined to a narrow beam, that is unseen from Earth. The study of gamma-ray properties exhibited by pulsars offers invaluable insights into the physics governing the emission regions on neutron stars.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
