IC 1795 Fishhead Nebula (Enrico Scheibel)

IC 1795 Fishhead Nebula

IC 1795 (nicknamed the Fishhead Nebula or Northern Bear Nebula) is a bright emission nebula of about 70 light-years across with glowing gas and dark lanes of obscuring dust, located just over 6,000 light-years away from Earth in the northern constellation of Cassiopeia. The brighter region of the nebula is designated NGC 896.

It is part of a complex of star forming regions that lies at the edge of a large molecular cloud called W3, along the Perseus spiral arm of our Milky Way, where star formation is most actively still going on. IC 1795 is located right at the tip of the heart in the famous Heart Nebula (IC 1805).

The stars inside IC 1795, energizing the nebula and making it glow, have not yet emerged from their natal cocoon. In other words, we can’t see the massive stars lighting up this nebula. This suggests that the stars inside are very young, on the order of millions of years. That is young in comparison to stars like the Sun, which is nearly 5 billion years old. These stars are also probably quite massive, since the nebula is so prominent and bright.

IC 1795 is recognized as being a very strong source of radio emissions.

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.
