A NASA probe has started its mission to map the heliosphere, which is a huge protective bubble around the solar system that was created by the sun, the space agency announced on Monday.The space agency's Interstellar Mapping and Acceleration...

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?

Voyager 1, NASA’s deep-space probe, is slated to reach one light-day from Earth in November 2026.

The term light-day refers to the distance at which it will take 24 hours for a signal or command traveling at the speed of light to reach the spacecraft from Earth. One light-day is equivalent to 16B miles (26B kilometers).

So if Voyager’s team is asking the spacecraft to do something once it reaches that point, it will take another day for Voyager to respond. “If I send a command and say, ‘good morning, Voyager 1,’ at 8 a.m. on a Monday morning, I’m going to get Voyager 1’s response back to me on Wednesday morning at approximately 8 a.m." https://www.cnn.com/2025/12/09/science/voyager-1-light-day-earth #NASA #Voyager1 #Space #SpaceCraft #Heliosphere #LightDay
