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)

Played it 3 times. Only saw one.

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?

We'll just tell your mother that we ate it all.

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

janus2, w Saturn has 128 new moons – more than the rest of the planets combined

“Did you bring enough to share with the whole class?”

the class:

PixTupy, w Juno reveals dozens of lava lakes on Jupiter’s moon Io

I read lava cakes and was very confused for a second.

neuracnu, w Juno reveals dozens of lava lakes on Jupiter’s moon Io

I’d love to have been in the room when Galileo sent back its first images of Io back in the day. The collective “wtf am I looking at?” reaction would be priceless.

blarth, w NASA cuts off international climate science support

Not with a bang, but a whimper.

acockworkorange, w Astronomers 'looked back in time' and found a double jet shooting from a black hole, twice the width of our Galaxy

Everybody is always looking back in time.

bane_killgrind, w NASA rover discovers liquid water 'ripples' carved into Mars rock — and it could rewrite the Red Planet's history

This is cool

very_well_lost, (edited ) w Cosmic disturbance: The mystery of Titan's shifting orbit

The study suggests that some event within the last 350 million years altered its trajectory, preventing it from settling into a circular orbit.

That’s within the current best estimates for the age of Saturn’s ring system… maybe the same catastrophic event that formed the rings is also responsible for the anomaly in Titan’s orbit?
