NGC 5253

This bright object is a blue compact dwarf (BCD) galaxy located 11 million light years away in the constellation of Centaurus at a declination of -32 degrees. It is a magnitude 10.5 galaxy which spans 4 arc-minutes in our apparent view. This corresponds to a small diameter of 15,000 light years.

BCD galaxies are believed to be young galaxies having the following characteristics:
- Small size
- Starburst galaxy, with active star formation
- Blue color, due to the high energy radiation of massive young stars
- Low metal content

NGC 5253 is one of the nearest BCD galaxies to us. For its small size, this object has vivid blue and purple colors due to its active star formation. It also has interesting tiny dust lanes, as better seen in the Hubble image of the mouseover comparison.

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.
