Probe! Probe! Probe! Probe!


I suggest Orion or Daedalus propulsion. I think we have a few pulse units lying around that might as well be put to that use as the plausible alternative.

Yes, because those poor overheated aliens really need a dressing gown around now :-P

I foresee more of this sort of thing as mobile devices catch on ... :oops:

Holy Dooley!


There is a planet with a mass comparable to Earth orbiting Alpha Centauri B! http://www.spacedaily.com/reports/Nearest_Star_Has_Earth_Mass_Planet_999.html


Yay! :)
Now that we know there's at least one house next door, how do we find out if someone's living there (Not this particular world which unpleasant, but maybe there's more)?

Well unfortunately, it seems to so close to AC-b that it is likely to have a molten rock surface. No water - no life.

BUT, where there is ONE planet, there is likely more planets and if AC-b can have planets, so might AC-a...

Handy-dandy illustration of the nearest stars to Sol, including how many planets they're known to have!

Astronomers Conduct First Remote Reconnaissance of Another Solar System

Astronomers claim to have studied the spectra of four red planets (I don't know their masses but I'll assume they're gas giants since that's most of what we've found so far) orbiting HR 8799 128 light years away. As temperatures are estimated to be around 1000 K, we're not talking Earth-like conditions, but as proof of concept it's great.

On the page you'll find a short video showing HR 8799's location with respect to Earth and a pdf with a link to the study.

We are well over 1000 charted exoplanets now. Anyone heard anything about probes, extended baseline telescopes a couple of AU appart or other improved ways of mapping things? Is it time to put more sensitive and capable radio ears into orbit?

Here is a nice find! HD 133131 is a binary system of two low-metallicity G2 main-sequence stars separated by 360 AU, lately discovered to contain at least three giant planets, at least two orbiting one star and at least one orbiting the other. The giant planets are in the 1.5 to 2.5 M range, in moderately eccentric orbits at about 1.4 to 6.4 AU.

Nice find! :)

"Astronomers have found a system of seven Earth-sized planets just 40 light-years away. Using ground and space telescopes, including ESO’s Very Large Telescope, the planets were all detected as they passed in front of their parent star, the ultracool dwarf star known as TRAPPIST-1. According to the paper appearing today in the journal Nature, three of the planets lie in the habitable zone and could harbour oceans of water on their surfaces, increasing the possibility that the star system could play host to life. This system has both the largest number of Earth-sized planets yet found and the largest number of worlds that could support liquid water on their surfaces."
