Dumbbell Nebula and Exoplanet HD 189733 b

Dumbbell Nebula (M27) an exploded star which use to be about the size of our sun, now a tiny white dwarf at the center, which is emitting copious amounts of UV and illuminating the remains. To the right circling a K2 star about 0.8 the size of the sun is an exoplanet about 1.2x that of Jupiter. My new game is measuring the light changes coming from stars with planets. By comparing the light of the exoplanet star to stable neighbors you can measure amazingly small differences. The light curve below was taken over about 4hrs. The Nebula consists of about 4hrs of LRGB data. The nebula is about 1300 lyr away the star is only 26 lyrs away. From the information you can learn things such as the ratio planet to star radius. It part of a citizen science program to beta test exoplanet software and eventually to help Pros keep track of the position of Exoplanets for future study with new giant telescopes.

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.
