NGC 3741 (John Bozeman)

NGC 3741

NGC 3741 is an irregular galaxy in the constellation Ursa Major. At a distance of about 10 million light-years (3.2 Mpc), it is located in the M94 Group. It is relatively undisturbed by other galaxies. NGC 3741 is an unusual galaxy in several aspects. It has a disk of neutral hydrogen (H I) that is extremely wide, extending some 23,000 light-years (7 kpc). The disk is strongly but symmetrically warped. With a mass-to-light ratio of MT/LB ~ 149, it is highly rich in dark matter. NGC 3741 has a central bar and a faint spiral arm rich in H I. The bar rotates slowly, likely due to interaction with the dark matter. The bar and spiral arms would make NGC 3741 a low-luminosity spiral galaxy. The unusual properties could be explained if NGC 3741 were a late-stage merger between a low-mass companion or if it accreted mass from the intergalactic medium.

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.
