This is not to say that there will not be some very exciting news! I can't wait!


Well this is my point. These aren't SETI folks on the panel. One's SST. One I believe had lots of work on Kepler. One is a the AD of NASA's science mission directorate I believe. They're all exoplanet folks. Kepler is the most popular exoplanet space instrument. Spitzer is certainly no small player in that as well. Arecibo is involved with that stuff in some light, but not as part of SETI.

Whatever it is, it should be big. My guess is the direct spectrographic imaging of water of a close earth-like planet occulting its host star.

Yep that's what I expected! But very cool to see that they discovered a star with 7 earth size planets and three of which or in the Goldilocks zone and one potential watery world. I am at work so I didn't get a chance to see the whole announcement but will read more about it when I am off. Cool news! Only thing I saw is that they mentioned the planets might be tidely locked because of the close proximity to the star. Not sure how conducive to life that would be given that one side is always daylight and temperatures might be quite higher and really low in the dark side. I suppose there may be a zone in the terminator where the conditions could be pleasant.

Ps: for those interested there is an iPhone app I have used for many years called exoplanet. It's a data base of all the exoplanets discovered and gets updated everytime new planets are discovered. You can do a database search on any of these planets and get lots of information about said planet and it's star! Certainly very cool and informative for those who love this stuff.

If a planet supports life, tidal locking really isn't a big player. It would only have serious implications of temperature with planets that don't have significant atmospheres... something complex life forms will need.

Given a low mass star that's only 500 million years old, I doubt those planets are all tidally locked anyways.

Either way, the most important thing for early life is that it's a spinning geologically active rock with the right stuff on it at the right temperature.

It's very exciting news - hopefully with advancements in instrumentation in the next few decades, we will be able to directly take spectra from objects like these.

On a non-political note, awesome news with all this science talk in here! Sounds like quite an exciting find, and I'm loving the discussion about it in here.

Yes I guess having a dense enough atmosphere would have a moderating effect on the temperature of tidely locked planets. Even if the temperatures are still higher then the normal temperatures of earth, life could still exist in the form of microorganisms. If anything life here on earth has been shown to exist in some very extreame environments like those found in fumerals at the bottom of the ocean where temperatures are quite high by the fumerals. Also it's positive news that the evidence they have regarding their atmospheres would suggest these to be rocky planets. So exciting all around. I too look forward to the next couple decades for improved technology to dig deeper into these planets. I think the James Webb telescope to be launched next year will help answer a lot of the questions regarding these planets.

here is another cool space news! Seems rather optimistic but if they can pull it off it would be awesome!

i see spacex has decided to go with the three-man capsule now. hope they have enough experience with the large rockomax launchers to make it work, the degree of difficulty goes up considerably with the extra size and weight. but as long as they use an experienced pilot like jeb or val they should be fine.

This announcement comes as my masters project was announced... development of a lunar surface to orbiter transport system. How... coincidental.

as in, designing a new LM for a manned apollo-style mission? or would this be more of a ship's tender kind of thing for an orbiting moon station to travel regularly to and from the surface?

this is all so exciting. i hope i'm around long enough to see these all these plans become reality.

The latter. Plans of the highest order are already in place for a lunar space station orbiter i.e. agreeable designs exist from the broadest level.

Thanks so much Dave for the very kind comments! I use a variety of telescopes (I have 3 of them) and a few different cameras that I attach to the scopes where the eyepiece would go. For most of the planet shots, Jupiter, Mars, Neptune etc I use my largest scope (a 10" Schmidt cassegrain) and I use either a webcam like camera (actually a modified security camera) that I can get the image on the computer screen directly) or I use an old canon point and shoot with a special adaptor. For my wider field images of the moon and sun and stars or deep sky, I use either 5" maksutov cassegrain telescope or an 80 mm refractor telescope and my Canon DSLR. DSLRs are great for wide field because of their large sensor sizes but for close ups of planets providing the atmosphere is clear and steady, the more power the better! Also the very tiny sensors of webcams usually under 1 MP are great for planets. I'll write a bit more in depth later as my phone is about to die

Edit: ok I am back now with my phone plugged in! As for the planetary shots including the closeup moon photos I actually take videos of the planets usually around 60-120 frames per second depending on the brightness of the objects. I then convert and split the videos to individual still images (I try to get atleast 1000 frames or more). Since the atmosphere is very dynamic there are moments of complete steadyness or no turbulence in which the images come out very sharp while other times the images appear very blurry due to the air currents. I remove all the blurry images and only keep the best ones. I then stack them together which reduces the noise and increases the details. The more images you stack the better the signal to noise ratio is and the better the image turns out. Usually I try to get about 500-1000 good images from a video to get a single better stacked image. This works great but on some planets like Jupiter all your images must be taken within a very short period of time because Jupiter rotates very fast and if too much time elapses between images, you can loose a lot of detail. Well this is the very short and condensed explanation of how I get my planet shots. It is a bit time consuming but the results as compared to a single raw image are just amazing. I haven't done much astrophotography lately due to time and the fact that at this time of year, the weather is garbage here in the west coast. Also I don't seem to have the energy I used to back when I was in my 20's lol so I often get too lazy to haul out and set up all my equipment which can take quite a bit of time to set up, align and get the images. I hope though to get back into it this summer. There is an awesome total solar eclipse on the 21st of August! I will probably drive down to Oregon where it will be best seen and set up somewhere there weather permitting.

I agree, going to the moon is a whole different animal then just LEO and the amount of things that can go wrong are much greater then low earth orbit. So I hope they are not setting themselves up for failure or a tragedy but I guess we will learn more about their plans later this year. I am glad though that there seems to be a will to go especially by private companies. I think the future success of space travel will depend largely more on private companies rather than NASA, ESA etc. And unfortunately unlike the 60's where there was a huge political motivation to go to the moon and beat the Russians, there seems to be little motivation to really push hard these days to go back to the moon and go to Mars! Sure there are plans now and Oroin and the SLS are taking shape, but the money is just not there so this process is really slow. I think private funding and the private industry is the way to go now. So kudos to space-X. I just hope they realize the extreame challenges. When I heard the 2018 timeline I get a little skeptical that they will be able to pull it off in such short time frame.

TBH, I'm not sure this really is a different beast in that sense. I'm pretty confident, given today's technologies, that a lunar flyby is virtually the same thing as putting humans in orbit around earth. Not actually the same thing, but similar. Quite frankly, I'm more worried about spacex putting humans on their rocket just yet. Gonna have to have a few less blow up upon launch before that's cool, IMO.
