So ground based observatories have long benefited from the development of adaptive optics. That's basically where you have a small mirror that is synced to the movements of the upper atmosphere and essentially cancels out the shimmer that makes stars twinkle to the naked eye, bringing them into a sharp focus more like what you would get from a space telescope. But the tech can only achieve this feat over narrow patches sky, meaning wide field observatories were left out. I think that's what they're talking about here? You can't get much more wide field than Vera Rubin.
I believe this is a new deconvolution image stacking algorithm that can easily be run in hardware. It should work with any observatory. The math is far enough above my head that I can’t be sure though.
It would be cool if this makes it into software that people could use at home. I would love to see what amateur astrophotographers could to with it.
Hopefully, this new algorithm is not overly taxing. The amount of processing they’ll have to do to keep up with Rubin must be staggering. It’s got what, a 3.2 Gpixel camera mapping the entire night sky every few days. And then all that data has to be processed across the timeline of past observations. I wouldn’t be surprised if the computational demands are what kept it from becoming a reality until now.
What kind of alien god is looking on from deep space in the upper right? I see two eyes, a mouth, and the dark shading varies just enough to look vaguely like a head.
I’m starting to think maybe I’ve had a few too many arguments intense discussions with alien conspiracy theorists…
What a fabulous post this has been. Never seen this kind of useful post. I am grateful to you and expect more number of posts like these. Thank you very much. AARP® Medicare
In the evolving digital economy, access and trust are everything. Whether it’s financial trading, online gaming exchanges, or digital platforms, users are constantly searching for a reliable way to authenticate themselves without compromising speed or security. That’s where the Diamond Exchange Master ID plays a crucial role. More than just a login, it acts as a master key that opens doors to platforms while protecting user identity and simplifying transactions.
Long days on the go often lead to fatigue and stiffness. Massage provides targeted relief, helping you feel lighter, more 출장마사지 focused, and ready to handle any challenge that comes your way.
When it comes to looking your best naples hair salons, nothing beats the confidence boost of a fresh hairstyle. That’s why many people say the best stylist salon makes a real difference, offering expert techniques, modern looks, and personalized service that leaves every client feeling stylish and valued.
The saga started two years ago at Caltech’s Zwicky Transient Facility located at the Palomar Observatory in San Diego County, California. There, astronomers from Harvard University, the Smithsonian’s Center for Astrophysics, and MIT tasked a newly designed machine learning algorithm to scan the night skies for odd explosions in real time. Operators hoped that quickly flagging possible targets in this way could offer vital extra time for ground and space telescope array observations around the world. In July 2023, the AI system sighted one such event, which astronomers classified SN 2023zkd.
Comparative scanning of the night skies is a good use for AI.
There’s lots of good uses for AI, but people seem to equate AI with LLMs these days so I feel the need to point out that this is not a good use case for LLMs
I have such mixed feelings about all the time I spent with my cameras during the event. By time I realized I had no practice with the camera and eq mount for daytime use, it was cloudy the whole time at home. Totality is not something you can reasonably practice anyway. So yeah, I have a few cool totality pictures with varying detail and a couple hundred showing the partial phases… But for what? They’re not as good as many other amateurs, let alone professionals. If there was ever a time to deal with the hassle of raw photos, it was then. Part of why I gave up on most astrophotography is because the best I could possibly do is simply match it to scientific equipment. It’s cool to do it, but there’s no personalization. Instead, I look more for nightscapes or wide angle really detailed starfields. I’m still conflicted as to whether or not I experienced it properly. I got to show the pics to some people passing by after, assuming I was the go-to person for info on what they experienced, something I love about night time astronomy, but those aren’t such time-limited events.
I’ll probably revel in memories whenever I actually flip through the pictures. But, personally, I don’t think it was worth spending so much of my time getting pictures of a black hole in a black background rather than just letting my mark 1 eyeballs observe the hole in the blue-fade skies.
However, the one piece I absolutely would bring every single time again is binoculars. Maybe that’s why I feel like I didn’t see the eclipse. The view in my 10x binos was so incredibly detailed, the memory matches the stacked and tweaked pictures. I could see more than just the big laser-don’t flare on the bottom, I saw at least 3. Just unreal, no sight in my life before could explain it. A cartoonishly large corona with a black hole in a black background. Maybe I just couldn’t comprehend.
The light effects near totality were certainly something to experience. Decades of experience being in sunlight just didn’t jive with what the sun was doing then. It was more akin to a distant white streetlight rather than a sun. It dimmed and crisped shadows unlike a sunset by not turning orange and blurring of the edges.
I’m glad you had the emotional experience I was expecting to have.
Yeah, my photography issues were similar, re: unfamiliar context. I’m still puzzled as to why the quicksetting menu works totally differently when using it in mirrorless mode. But oh well. There’s always… 2044??? Oh, crap.
I admit, other than a better lens with a tighter view, the bits of equipment I really wished I’d invested in were a tracking motor and a shutter remote. I paid zero attention to my camera during totality, but I still had this nagging voice in the back of my head telling me that I should check my centering, and I didn’t need that.
To potentially save you the confusion I had, the next popular one in North America will really be 2045. They’re both in August, but the 2044 TSE is a relatively short, northerly event with totality ending in Montana at sunset. Meanwhile, 2045 is more akin to the 2017 path, passing from California to Florida.
I had a similar concern earlier. Most people don’t realize that the right setup can completely change comfort and style. When I was researching options, I found some detailed insights on window treatment , and it helped me understand what works best for different rooms. Sometimes it’s just about choosing the right balance between function and design.
Yeah, not much of an emotional reaction from me, beyond a slightly incredulous laugh and an extended wow punctuated by gawking in awe. Definitely should have brought my 'nocs!
