M101 with SN2023ixf ~ 29 Jun 2023

SN 2023ixf is a type II (core collapse) supernova located near a prominent HII region, NGC 5461, in an outer spiral arm of the Pinwheel Galaxy (M101). The supernova is about 21 million light-years from Earth and is expected to have left behind either a neutron star or black hole based on current stellar evolution models.

It was first observed on 19 May 2023 by Kōichi Itagaki and initial magnitude at discovery was 14.9. After discovery, the Zwicky Transient Facility project found a precovery image of the supernova at magnitude 15.9 two days before discovery. By 22 May 2023 SN 2023ixf had brightened to about magnitude 11, and started to fade on around 10 June 2023.

The last supernova this close to Earth was SN 2014J in Messier 82, roughly 12 million light-years from Earth.

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.
