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?

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)

Paragone, w Curiosity Mars rover discovers largest organic molecules ever seen on Red Planet

Alkanes, from the possible breakdown of fatty-acids, in distant past…

To me, the question then becomes … is there any nonbiological-method for Mars to have produced those molecules?

IF so, THEN … probably that’s how they got there…

but without knowing the answer to that question…

it isn’t decided, is it?

Man I need to get my scope out again. It’s been years. Maybe one of these days…

threelonmusketeers, w Asteroid 2024 YR4 now has a 1.94% chance to hit the Moon (according to my own calculations)

Do we know if the Moon will be in the correct phase in it’s orbit when 2024 YR4 comes by? I didn’t notice a term to account for that, but I’m not too familiar with Desmos.

LostXOR,

The calculations for the close approach data I'm using to calculate the probability already take the Moon's orbit into account.
