IC 434 is an emission nebula in the constellation of Orion, about 1500 light years away from us. Its average temperature is about 6000 K. The nebula is illuminated by the star Alnitak, a young and hot star of spectral class O9.5, which ionizes the hydrogen atoms in the nebula, making them emit red light in the visible and blue light in the infrared. Inside IC 434 there is the Horsehead Nebula, a dark cloud shaped like an equine, also known as Barnard 33. Nearby there are also NGC 2023 and NGC 2024, two reflection and emission nebulae that contain young and hot stars. NGC 2023 reflects the light of the star HD 37903, a star of spectral class B2, and is one of the largest reflection nebulae known, with a diameter of about 4 light years. NGC 2024 has an irregular shape and contains a cluster of stars visible in X-rays. All these nebulae are part of the Orion molecular cloud complex, a region rich in star formation. To see them you need a powerful telescope and an H-alpha filter. Long exposure photos or CCD images show the details and colors of the nebula.

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.
