M101 Galaxia del Molinete

Distancia a la Tierra: 20,87 millones años luz
Radio: 85.000 años luz
Estrellas: 1 billón
Constelación: Osa Mayor

Fue descubierta por Pierre Méchain el 27 de marzo de 1781, quien posteriormente comunicó su descubrimiento a Charles Messier que verificó su posición y la añadió al Catálogo Messier como una de las últimas entradas.

Es una de las galaxias más grandes existentes en la vecindad de la Vía Láctea, con un diámetro de más del doble que ella, y se caracteriza tanto por su riqueza en gas para formar nuevas estrellas cómo por su elevado número de regiones HII (más de 3000, algunas tan grandes y brillantes que tienen número NGC propio y que han sido estudiadas por el Telescopio Espacial Hubble, mostrando la presencia de super cúmulos estelares en algunas de ellas) y de cúmulos estelares jóvenes (también estudiados por el Telescopio Hubble), esto apunta a una elevada tasa de formación estelar. Ello junto a su asimetría hace pensar, en términos astronómicos, que hace relativamente poco otra galaxia estuvo a punto de colisionar con ella, causando ambos fenómenos.

Esta galaxia tiene un bulbo casi inexistente, y de acuerdo a estudios recientes parece carecer de agujero negro supermasivo en su centro, a diferencia de, por ejemplo, nuestra galaxia.

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.
