buggy-pull-buggy, w Citizen Astronomers Help Confirm New Temperate Jupiter

That is pretty f'n sweet

emuspawn, w Astronomy has a major data problem. Simulating realistic images of the sky can help train algorithms
@emuspawn@geostationary.orbiting.observer avatar

What kind of algorithms are those trains running?!

Make sure you check out the simulator webpage for some sweet old school design and a lot of neat pictures! I love a good simulation.

bleistift2, w The Cosmic Owl: Astronomers discover a peculiar galaxy merger

[…] only a few hundred of them have been detected in the local universe

Why haven’t they checked other universes?

Flyberius, w “The models were right”: astronomers find ‘missing’ matter

Nice. It’s a huge cock and balls

Winged_Hussar, w Learning The Basics Of Astrophotography Editing
@Winged_Hussar@lemmy.world avatar

Always appreciate updated and current videos on the process, even if I can’t mimic on Linux.

Something that has always frustrated me about the editing process is that every program has its own unique features

Some you get wavlets

Some you get stacking and aligning

Some you get level adjustments and curves

All while most of the programs are deprecated and/or abandonware

I think currently I have Registax, Auto Stakkar, Siril, PiPP, and Gimp installed for processing just because some programs perform features better than others.

abcdqfr, w 1.5TB of James Webb Space Telescope data dumped on the internet — new searchable database is the largest window into our universe to date

Tangent, how would this telescope do turned around and pointed at our deepest oceans? There’s infinitely more alien life to actually find and study, and it’s still unstudied for good reasons I suppose I’m fishing for.

Wait… what?

We’ve got tons of oceanographic satellites. James Webb is extremely good at picking up light. The ocean is extremely dark.

RedSnt, w Milky Way may not be destroyed in galactic smash-up after all

But don’t worry either way:

Phew!

no galactic smash-up is expected for billions of years, long after our ageing Sun will have burnt away all life on Earth.

Timecircleline, w Milky Way may not be destroyed in galactic smash-up after all

The one thing I had to look forward too. Dang.

keepthepace, (edited ) w Johannes Kepler's accidental marriage equation – ParallaxNick (15:42)

Everytime he is mentionned this webcomic en tête springs into my mind, and I can’t help giggle out of it.

Took me a minute… I have to jump through many self made hoops to get new websites through my firewall’s DNS filter and I don’t enable http. It is however on archive. I’m probably the only nerd here with such masochistic network, but whatever. Thanks for the comment. Tycho was a character, that’s for sure.

anguo, w "Big surprise": astronomers find planet in perpendicular orbit around pair of stars

Isn’t that literally the premise of the Three Body Problem?

teft,
@teft@lemmy.world avatar

The 3 body problem has no general solution. This would be a special case solution.

anguo,

Ah, yes, I just read the title again!

Bldck,

Not exactly. In the novel/tv show the Three Bodies are stars that are interacting with a fourth object, the planet Trisolaris.

Because the movements of the three suns are unpredictable, they never know when the climate of the planet will be habitable.

anguo,

Yes, I remember now that I thought “that’s a four body problem” when I read it.

Balthazar, w Scientists hail ‘strongest evidence’ so far for life beyond our solar system

In the best case, the detection is at the 2.4 sigma confidence level (less than the usual 3 for reasonable confidence and will below the 5 required for strong confidence), and if previously suspected issues with the instrument are true, the detection could disappear completely.

I do not have a strong confidence in this result. (But at least they didn’t publish it in Nature, in which case you would absolutely know it’s wrong…)

SolarMonkey, w For the first time, astronomers watch a black hole 'wake up' in real-time

Are the tracking systems for those massive telescopes sophisticated enough to track objects by designation, or do they still require coordinates? Like I know they have tracking for earths rotation but I can’t even imagine needing to look up the info to set sights on some body for the allotted view time, however many days that would be done for (I assume it’s a set of long precise numbers, far too long to easily memorize)
