Whale Galaxy

At 30 million light years from Earth, the photons collected to make the picture of NGC4631 (the Whale Galaxy)started their journey in the later half of the Rupelian age. The beginning of the Rupelian age, named for the Belgium river Rupel, saw the formation of the first Antarctic permanent ice-sheets.

On geologic timelines...

* the Rupelian age is in the Oligocene epoch

* the Oligocene epoch is part of the Paleogene period

* the Paleogene period is in the Cenozoic era

* and the Cenozoic era is part of the Phanerozoic eon

The Cenozoic era is the current era and we are in the:

* Quaternary period (-2.6 million years to present)

* Holocene epoch (-12 thousand years to present)

* Meghalayan age (-4.2 thousand years to present)

But the Anthropocene epoch is proposed to begin in 1950 to mark the impact of humans on Earth's geology and ecosystems. As of March 2021 this has not been approved so technically we're still in the Meghalayan age / Holocene epoch?

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.
