NGC 1555, also known as Hind's Variable Nebula, is a reflection nebula illuminated by the variable star T Tauri, located in the constellation of Taurus. It's a Herbig-Haro object. These are small nebulous formations around young stars. They are formed when gas ejected from the star meets clouds of dust. Herbig-Haro objects are ubiquitous in star-forming regions. Often they are seen around a single star where they are aligned along its axis of rotation.
Herbig-Haro objects are very short-lived, with a lifespan of a few thousand years at best. They can become visible in a very short time as they move rapidly away from their star of origin and into the cloud of gas in interstellar space (also called interstellar matter).

The nebula complex with the central small Hind's variable nebula lies north of the Hyades at a distance of more than 400 light-years. Dust clouds reflect light from variable star T Tauri. It is a protostar in a phase between cloud collapse and stable hydrogen burning. Its brightness fluctuates irregularly between magnitudes 9 and 14. Consequently, the brightness of the nebula also changes.

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.
