Long time since I was able to post a new image here.
I got a partial Milky Way shot.
Limited in field of view and framing due to a crappy stock lens, light pollution and roofs.

that out of the way, I think it’s pretty great for my lack of widefield experience.

Nice picture. :mallory:

Given that you had to contend with light pollution, I think you did an admirable job.

Scientists going through data from the now retired Kepler space telescope have discovered something not seen before.

it captured the complete collapse of a star into a supernova and the resulting shockwave.

I have to learn to process RAW video footage better (debayer etc) to get the color information.
But here is a composition of Saturn and Jupiter I shot a few days back.
It’s stacks of hundreds of video frames, processed in a couple of Astrophotography applications.
I shot with a dedicated planetary camera and my Newton telescope.
Surprisingly even 3 of Jupiter’s moons are visible.

Hi everyone. i got two new, very different images to share.
You'll recognize both objects, I'm sure.

"In an everyday sense, the findings seem to surprisingly suggest the ability to produce light from the empty vacuum"

Perhaps even more strange:
https://phys.org/news/2021-09-non-radiating-source-electromagnetism.html

For many years, physicists have grappled with the idea of "meta-atoms," macroscopic objects that have alternating current that prevents the emission of electromagnetic energy....The device consisted of a simple radiating antenna placed inside a hollow dielectric disk with high permittivity—a setup that allowed the disk to be smaller than the wavelength of the emitted radiation. The researchers note that the design of the device was such that the electromagnetic radiation emitted from the antenna would interfere in a destructive way with waves produced in the dielectric disk, where they would cancel each other out.

I wonder if dark matter can hide this way...

Speaking of hiding…we may have narrowed down Planet Nine’s locale:

"This totally unexpected result can have transcendental implications, not only for our understanding of the large-scale structure of the universe, but on the settings for the creation and evolution of galaxies," explains Vicente Quilis, director at the DAA and head researcher for the project.

"Cosmic voids are the largest structures in the cosmos, and knowledge on their creation and evolution is essential to understand the structure of the universe," says Susana Planelles, co-director of the research.

This new finding, from research led by Imperial scientists, improves our understanding of the conditions around Earth that contribute to ‘space weather’, which can impact our technology from communications satellites in orbit to power lines on the ground.

I have to clarify this one. It's not an actual image but a photoshop that went viral......Not our Sun

There Be Whales Here · Dec 8, 2021

While I've been into amateur astronomy since my teen years, it has only been in the last few I've dabbled in the photographic end of it with hit and (mostly) miss results. All of my attempts so far were taken with an older 12 MP digital point & shoot using a Meade EXT 70, so I know it won't come close to rivaling some of the stellar (no pun intended) examples here. But I present some of what I've determined are the most successful, but at the same time know they are nothing to write home about considering my limitations in both equipment and experience.

I'm still trying to sort most of the wheat from the chaff, but just to start off as a sample.
First one brief lunar image at low mag.

And a collage of my planetary attempts of Venus, Mars, Jupiter & Saturn also at low power.

Please be kind
