Here we see the adolescent star CW Tauri nestled in part of the Taurus Molecular Cloud. It is the lower right star of the triad found at the center of this stellar cavern. It is a spectroscopic K3 T-Tauri star, cooler and more orange/red than our sun. This Young Stellar Object has bipolar jets that are not visible at this scale and wavelength. At Ha and SII wavelengths, a nearly one parsec optical out flow has been detected. Herbig-Haro object 827 can be seen to the right, and is thought to be associated with the outflow. The T-Tauri star varies in luminosity on a fairy short time scale. (As much as 2 magnitudes in as many months) This variability could be due to a variety of causes, including mass infall from the circumstellar accretion disk or periodic transiting of surrounding clouds. As time passes the protostar will evolve to a point where critical core temperatures allow fusion to occur and a main sequence star is born.

“Silently, one by one, in the infinite meadows of heaven, blossomed the lovely stars, the forget-me-nots of the angels” (Henry Wadsworth Longfellow, Evangeline: A Tale of Acadie)

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.
