NGC 1555 is a quite strange target, it is a socalled Herbig–Haro (HH) object, a nebulosity associated with newborn stars. It is sometimes known as Hind's Variable Nebula, after the astronomer who discovered it in the 19th century. This nebulosity is a variable illuminated by the star T Tauri.

As bad weather and professional commitments prevent me from doing some pictures in my Normandy's observatroy 100 km away from my home in Amiens I decided to buy data from Insight Observatory. I did not use the L layer, 10x300s each RGB. Taken with the f/3.7 astrograph reflector (ATEO-1).

Looking at this picture I cannot help but think about our human body which is 96% composed of four elements : hydrogen, oxygen, nitrogen and carbon. A human cell has about 10e14 atoms and a human body about 10e14 cells. One estimates the number of galaxies in the known part of the universe to some 10e11. Amazing, isn't ? Why we don't teach this to all kids on this planet ?

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.
Dismissals 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.
