Sh2-142: The Wizard
Discovered by Caroline Herschel in 1787, Sh2-142 is an open star cluster ~20ly across located ~8.5kly distant. A beautiful emission nebula and star-forming region.

In 2024, Opher et al published a paper in which they describe how from a few million years ago, a cold hydrogen cloud started to traverse the solar system https://www.nature.com/articles/s41550-024-02279-8
Here's an app from the authors:

The cloud dented the #heliosphere and so, exposed Earth to more incoming cosmic rays. And its hydrogen probably did stuff to the ozone layer too, and maybe to the methane concentration.
Huge impacts on #climate.
My question is, can #astrophotography still capture this cloud? What would it look like, photos with more blue tint than photos taken away from the cloud?
I'd imagine, it would be visible only seasonally, given how its location is now "to the left" of the sun.
I would love to search on Astrobin if I only knew how to translate the cloud position today to #deepsky objects.
Can you help?

Modelling suggests that the Solar System may have passed through a cold dense cloud 2–3 Myr ago, in agreement with geological evidence from 60Fe and 244Pu isotopes, putting Earth in direct contact with the dense interstellar medium with potentially substantial impacts on its climate.
