Suddenly Dr Crusher’s achievement to fly a Galaxy Class ship with special magic metaphysic shielding into a sun’s corona feels a lot less impressive!

NASA has official achieved this goal this year with the Parker Solar Probe for the first time in human history.

I returned to the Orion Nebula together with my Physics Professor, testing out new imaging equipment (dedicated Astrocamera and a filter wheel among others).
Here's what I could make of the collected data, about 15 minutes each channel (LRGB + H-alpha)

That's really nice! Captured lots of detail.

Thank you. I still feel like an OIII layer is missing for some blue reflection glow contrast.

And I need to get better at Star processing.

That looks great. :mallory:

New observations suggest that dark matter’s not as ubiquitous as scientists thought.

Jupiter
https://phys.org/news/2022-05-jupiter-inhomogeneous-metallicity-clues.html

An international team of astronomers, led by Yamila Miguel (SRON/Leiden Observatory), has found that Jupiter's gaseous envelope doesn't have a homogeneous distribution. The inner part has more metals than the outer parts, adding up to a total of between 11 and 30 earth masses, meaning 3–9% of Jupiter's total mass. This is a high enough metallicity to conclude that kilometer-sized bodies—planetesimals—must have played a role in Jupiter's formation.

Yes they described that as the two planets kissing if you viewed through a telescope on our evening news last night. I just couldn't stay up for this.

Wouldn't that be long dead now, I mean as fun as that idea sounds and all?

Yeah, I'd think that its battery would have long died, and not to mention its orbit having decayed.

Gingerbread Demon · May 3, 2022

But even if it was artificial would we even be able to tell? I mean every 18 minutes sounds very regular...

Owain Taggart · May 3, 2022

You mean the signal? Sure, there are always ways. It's just a matter of finding the right frequency and looking for something regular while filtering out the noise. The fact that it's regular actually makes it easier to pinpoint, because then you know what to look for.

Yes I meant that signal. Very, very regular and they should be focusing on that and really try to determine what it is in more detail.

Owain Taggart · May 4, 2022

Yeah, I have a friend who's into radio astronomy, with a homemade antenna in his backyard, and it's basically what he does. He finds the strongest signals then, with software he tries to identity patterns. Sometimes all it is is noise and interference, but sometimes it can lead to interesting results. He passes that info on to an organization which can use that info to help triangulate some data. If enough people doing this look at the same thing, from different locations, it can then lead to discoveries.

Seth Shostak is the go-to guy go interviews these days…Jill taking days off, but there was a loveable off-ramp in a Netflix documentary called:

“John Was Trying To Contact Aliens.”

This was a film by Matthew Killip…son of photographer Chris Killip, as reported by Sean O’Hagan in The Guardian: “The man who tried to contact aliens from his grandmas living room.”

So help me, I’d have John Shepherds Project STRAT and Emory Blagdon’s work and George Van Tassels nonsense (if not coral castle) all as an art exhibit somewhere. At least Shepherds looked to broadcast. The guys at The Long Now Project should have threw him a bone.

Quiet men with butterflies…or John and STRAT.

But we throw money at NASCAR and basketball. Sickening.
