Lagoon Nebula & Trifid Nebula

The Lagoon Nebula (M8) and the Trifid Nebula (M20) are a pair of famous celestial objects located in the Scutum-Centaurus Arm of the Milky Way, both approximately 4100 light years away from Earth.

The Lagoon Nebula is a vast emission nebula and a star-forming region, spanning about 110x50 light years, embedded within it are protostellar materials and a group of young, hot stars.The Trifid Nebula is a rare combination nebula, encompassing emission nebula (red part), reflection nebula (blue part), and dark nebula (dark gaps within the emission nebula).

The Trifid Nebula is also a star-forming region, containing open clusters and many young stars.

Using a small, short-focus refractor telescope, both nebulas can be captured at the same time. Part of the Scutum-Centaurus Arm where the nebulas are located is also captured in the image, presenting a dark yellow color due to the abundance of gas and dust within the arm.

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.
