M101 Supernova SN 2023IXF - 22 May 2023 vs 2021 data (Mau_Bard)

M101 Supernova SN 2023IXF - 22 May 2023 vs 2021 data

Supernova SN 2023IXF
A new supernova, dubbed SN 2023IXF, was discovered on 19 May 2023 by Japanese astronomer Koichi Itagaki and subsequently located on automated images from the Zwicky Transient Facility two days earlier. SN 2023ixf occurred in the photogenic Pinwheel Galaxy M101, which, being only about 21 million light years away, makes it the closest supernova seen in the past five years, the second closest in the past 10 years, and the second supernova found in M101 in the past 15 years. Rapid follow up observations already indicate that SN 2023ixf is a Type II supernova, an explosion that occurs after a massive star runs out of nuclear fuel and collapses. The featured image shows home spiral galaxy on 22 May 2023 ago with the supernova highlighted, while the roll-over image shows the same galaxy in spring 2021. SN 2023ixf will likely brighten and remain visible to telescopes for months. Studying such a close and young Type II supernova may yield new clues about massive stars and how they explode.

What is Zwicky Transient Facility (ZTF)?

The Zwicky Transient Facility (ZTF) is a public-private partnership aimed at a systematic study of the optical night sky. Using an extremely wide-field of view camera, ZTF scans the entire Northern sky every two days. The resulting large area survey will enable the astronomical community to pursue a broad range of time-domain science ranging from near-Earth asteroids to the study of distant superluminous supernovae. ZTF is funded in equal part by the US National Science Foundation and an international consortium of universities and institutions.

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.
