You did a much better job of explaining that in layman's terms than I did >.<


I thought you did fine; you actually explained what it meant to "support liquid water."

I think that depends on what you count as direct detection. My understanding of it is much as you described earlier: that the changes in starlight spectral patterns as it passes through the planet's atmosphere is analyzed to make conclusions about the size and atmosphere of the planet. To the best of my knowledge, any "observation" of an exoplanet is in the form of what amounts to a one-pixel picture; there is no "image", but the "colors" the planet shows up in (and blocks) can be used to assess composition.

So it's clear that not a lot of serious discussion is gonna come from this, which is fine.

So... who here would be okay with being one of the first to attempt procreation with an alien species?

I would do it. FOR SCIENCE!!


As an impersonal and indifferent concept, science wouldn't care - and couldn't mourn your death from the alien STD you'd get. But we all would. Don't have sex with the alien, octorockandroll.

We'd still need a lot of nuclear rockets to get to even the closest of them. What we really need to do is convert the solar system into a single self-propelled Dyson Sphere and go rampaging through the universe.

I stand corrected.

However, it still seems from the description there that it's only useful for finding/ imaging exceptionally large planets (which they amusingly use "masses of Jupiter" as the comparative yardstick), not Earth-size terrestrial planets.

I'll buy a planet. I'll name it "imoutoworld", and let imoutos run free and in the wild, where they belong, with a sweet, lovable onii chan such as myself to keep watch over them. Yes, it will be a xanadu of imoutos!


And then I, Allie Cat, Will swoop in and free the imoutos! Free them from the overlord that is Lecher PV!

Yeah, it's a pretty special case. They try all sorts of things in the exoplanet community; I think microlensing is the most absurd. Eventually I stopped going to the exoplanet talks, though, because they got boring.

Heh. Yeah, I've found that pretty much any topic, when examined in sufficiently fine detail, can get pretty tedious.

What's microlensing?

From the NASA release:

The planets also are very close to each other. If a person was standing on one of the planet’s surface, they could gaze up and potentially see geological features or clouds of neighboring worlds, which would sometimes appear larger than the moon in Earth's sky.



That would be crazy seeing another civilization above you but not being able to communicate with them.
Maybe they thought that the others were gods and vice versa. It really is mind blogging.

Oh come on, you know I'm not dumb enough not to use alien condoms.

I'll admit, THAT part struck my fancy, too.

...I wonder what it would do for tides? For that matter, I wonder how stable the orbits of each planet are? With other planets passing so close, that might cause interesting orbital fluctuations.

Yessss I was reading it this morning.

This is great news.

I was just watching the New Cosmos on Netflix that show makes you feel very very small

I quote The Galaxy Song by Monty Python.

So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth;
And pray that there's intelligent life somewhere out in space,
'Cause there's bugger all down here on Earth!
