Messier 1 and Growth

Revision:
Growth from 1999 (Hubble Image) to 2023 (Planewave image) illustrated in GIF in revision B.

Over the years I have loved studying, imaging and exploring the Cosmos that surrounds us. It has filled me with awe and wonder and continues to do so today. I realized the other day that I had never pointed my telescope at this 1st object catalogued by Charles Messier.

Title: M1 Growth- Hubble 1999 to Planewave 2023

Description: On March 16th of this year Detlef Hartman posted a remarkable time-lapse of M1. Images that he himself had taken for 14 years (2008-2022). I highly recommend you check out his post.

I thought I might try and compare my image to the Hubble legacy image of M1 taken back in 1999. While this GIF is not a time-lapse from year to year, it does show the difference in size over the 24 years span. Here are some details regarding the expansion rate and estimated growth during that time.

M1 lies 6500 distant and went supernova in 1054 AD. It is expanding at 1500 km/s, or 0.5 % light speed. In 24 years it would have expanded 1.13 x 10^12 km, or .12 light years. Hubbles image was taken with narrowband filters, mine with broadband, but one can still get an idea of the expansion over this time period.

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.
