  • Gliese 876 I

    Has anybody heard anything about this?

    To me, it's no surprise. I mean, if our star system produced both terrestrial and Jovian planets, then it's pretty obvious that most do.

    Recently, there was a reckoning. It occurred on November 4, 2014 across the United States. Voters, recognizing the failures of the current leadership and fearing their unchecked abuses of power, elected another party as the new majority. This is a first step toward preventing more damage and undoing some of the damage already done. Hopefully, this is as much as will be required.

    Yep, I did a couple of days ago on the Astronomy Picture of the Day (APOD). Not of the actual planet, of course, but it had a small blurb.

      I'd heard about all the neo-Jupiters they'd detected, and even the one planet they managed to spot visually (yes, a tiny blip right up against stellar glare, but they do have a picture), but not this one. Actual earth. Er, more like Mercury, but hey. Take what you can get.

        I had a discussion about this with someone yesterday. They were bitching about the planet being called "Earth-like." The deal is, the planet is Earth-like in its terrestrial nature as compared to the Jovians. For years, Venus and Mars have been described as "Earth-like." So, in that context, the description is apt, as the planet is indeed an inner "Rocky."

          And very much "inner" for what I have read... two HOURS per "day"? Well, that's quite fast and I guess it is a very narrow companion to its star.

          Problem is we have problems detecting smaller Planets because they do not distrub their star enough to measure the "wobble". This new planet is only two times the radius (although est. 7 times the mass) of earth, so it is one of the smaller ones detected.

          I'm still waiting for the space-bourne Interferometer to happen. You could even get the spectrum of a planet (s atmosphere) as it is moving in front of its star. Now it would be mindboggling if we could detect Oxygen in the atmosphere of a distant world, because as far as we know only living organisms can set oxygen (in measurable amounts) free! "Instant live detector"? 8-)

          Still: Sad we don't have any good transportation method available and can't even think of a feasable way to travel to the stars... c'mon, negative energy? Wormholes are not feasable, as far as I am concerned...

            Travel the way you'd travel to McDonalds? No. Travel the way ancient explorers did, load up a ship for living and spend exhausting amounts of time travelling? That'd do it.

            Only four real things stopping interstellar travel. (1) Not cheap enough. Whenever they finally build a space elevator and stop using rockets to move things into orbit, you'll see a rush of space-bourne stuff. (2) Practicality. No real need when we haven't even bothered checking out our moon for decades, nor Mars yet at all. We have enough on our research and feasability dinner plate right here. (3) Patience. Rare commodity in the best of times. (4) Lack of a place to go. Exploring space now would be like setting out from Fiji and hoping to hit Hawaii by picking a spot randomly on the horizon. If they ever do get that Inferometer running, that'd help that.

            Given all that (!), you just need a big long-burn rocket, protein in all the colors of the rainbow, and a bunch of suckers. And lots and lots of time.

              Aw, crap! So I guess spending my life savings on that parcel of land on the new planet was a dumb idea

                I think if it is ever done, it will be done by a private venture, rather than a government-funded project.

                Did anyone ever see that near-fantasy documentary on The Science Channel about interstellar travel? They postulate that we will genetically modify the travellers on the "generation ship" before setting out: Four arms instead of legs (for movement in a zero-G enviro), the skin and mass of bodies (to allow to go longer periods of time in zero-G and with less water), etc. It was pretty funny, really.

                  Scientists are more cautious than you. "One data point does not mark a trend."
                  Lacking a general model for planetary formation one can't assume that our Solar System is the norm.

                  Sure, many scientists will speculate and make public those speculations, but most would wait for actual data before assuming something as "obvious."

                  That Science Channel show you saw is old, I think I saw it on TLC originally. Interesting far out speculation at the end. I personally don't give any credence to the idea of the four armed genetic engineered person, but who knows what might happen and how the perception of what is human would change for those that leave the craddle.
                  Such... is the respect paid to science that the most absurd opinions may become current, provided they are expressed in language, the sound of which recalls some well-known scientific phrase

                    It's almost somehow wrong, kind of like how the Vorlons modified humans to be telepathic. It's...unnatural. Modifying people in any way would create a rift in the human race. It'd lead to something like genetic cleansing, trying to make the "perfect" human.

                        I once read a nice short story about a bunch of people who choose to leave earth to make a whole new start for the better on another planet.
                        Didn't take long before the new one was as much fucked up as the old one.

                        Another one dealt with a guy who was in space and acquired the ability to read other people's minds. He was looking forward to coming back to his wife n kids n stuff. When he did he couldn't help but reading the minds of his wife's, kids' and some more people. Took him about two weeks before he set sails for the stars again.

                        Personally I think that mankind willl be extinct way before they would actually have developed means to do spacetravelling or telepathy on a larger scale.

                          Luckily, that's a personal thought.
