29P/Schwassmann-Wachmann comet

29P/Schwassmann–Wachmann (29P) is a periodic comet that orbits the Sun once every 5.3 years. Discovered in 1930 by Arnold Schwassmann and Arno Arthur Wachmann, this comet is notable for its bright and extended coma, or cloud of gas and dust, produced by the sublimation of frozen material on its surface (technically speaking it's more asteroid than comet).

The nucleus of 29P is estimated to be about 3.2 kilometers in diameter, and its coma can reach a diameter of up to 6 million kilometers. The comet's orbital inclination is approximately 6.3 degrees, meaning it follows a relatively circular path around the Sun. As it approaches perihelion – the point in its orbit where it is closest to the Sun – its coma can become particularly bright, making the comet visible to the naked eye.

The composition of 29P is fairly typical for comets, with a mix of volatile compounds such as carbon dioxide, water, and methane, as well as dust particles and organic molecules. During its close approach to the Sun, these materials sublimate and form the coma, which can be observed in visible light as well as infrared and ultraviolet wavelengths.

29P has been studied in detail by various astronomical instruments, including the Hubble Space Telescope, which has allowed researchers to map the rotation of its nucleus. The comet has also been observed in great detail using ground-based instruments, such as the Very Large Telescope in Chile.

The project included eight photographic sessions (two of them with my telescope and six with iTelescope observatory), spectroscopic measurements (unfortunately unsuccessful), photometric measurements and analysis of the nucleus by the Larson-Sekanina algorithm.

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.
