back to article Pack your bags! NASA spots SEVEN nearby Earth-sized alien worlds

NASA has discovered a mini solar system of seven Earth-sized planets orbiting a small cool dwarf star, including three within the Goldilocks zone where liquid water is possible. Last year, a telescope in Chile – dubbed the TRAPPIST aka the TRAnsiting Planets and PlanetesImals Small Telescope – spotted two planets orbiting an …

    I tried the "travel poster" link and it shows the message "Web application could not be started" along with all sorts of info like the application root directory, environment variables, user and group info, ruby config settings, and load and library paths. To me that's like showing phpinfo() for a crashed php page. Why would it do this?

    Grr. Some back of envelope maths, and I can't fit these planets into the Titius-Bode sequence. This annoys me. Still, there could be missing bodies, or other information we don't have (yet) that will change that.

    1. tacitust

      Well, this will be a very good test to see if that hypothesis holds up (and it is only a hypothesis). The interesting thing is that the planets are close enough together that Spitzer can detect variations in their orbits every time they pass in front of the star. There's a lot of interaction, yet they have very likely been in stable orbits for billions of years.

      One thing's for sure. We're going to learn a ton of orbital mechanics and planetary science just from this one system alone, and now we know where to look, we're going to find a lot more like it.

    2. Mage Silver badge


      They do have interesting resonant orbits.

      The "goldilocks" zone might be too close to star, so planet(s) might be tidally locked or periodically hit by solar flares. Both mitigate against life.

      The Talmud suggests there are 18,000 planets with life. Given number of stars in the Milky Way, that might be a serious under-estimate.

      We are only at the beginning of this kind of search. The James Webb telescope will allow search for biological or industrial activity via better spectroscopic analysis.

    Tides and stuff

    Isn't part of the current theory of why advanced life evolved here that the tides, night and day and the seasons were important. These planets will lack all that. So maybe bacteria, Fred the chimp not so much?

      Not necessarily - in a system that crowded you may have one or more with large enough satellites to prevent it from being tidal locked to the star.

      Re: Tides and stuff

      It's very hard to put any meat on any hypothesis when you're working with a sample of one -- Earth. Those who favor the "rare earth hypothesis" will point to all the factors that created Earth's environment, from the large moon, plate tectonics, Jupiter's role in sweeping up the debris in the inner Solar System, the Sun's stability, and on and on.

      But, in reality, it's all conjecture until we have more sample data to work with, since we don't yet even have a clear understanding of the events that led to abiogenesis here on Earth. We don't know which conditions are required, which conditions simply improve the chances, and which conditions have no impact. If life on Earth got started among the deep ocean fumaroles as some scientists propose, it could reduce the number of required conditions quite considerably, given the protective covering of miles of water.

      That doesn't really help when considering the advent of intelligent life, but one step at a time...!

    I always love the way people assume life evolved on earth. No prebiotic soup, inhospitable conditions and not enough time. Plus we can't actually make a cell WITH intelligent design let alone without it. Then we have the problem of how error correcting coding in DNA got there by chance. Philosophically those clinging to the Darwinian model are no better than someone observing a firing squad of a million shooters all missing the condemned man and insisting they did so by chance... and please before some Dawkins fanboy trots out the mantra ' but evolution is a fact' please remember that the only field tests of bacterial evolution show that any animal over 4kg will not produce enough beneficial mutations to explain the rapid speciation in the fossil record.

      Really, a creationist?

      Deny it all you like, but evolution *is* a fact. There is more than enough evidence for evolution for that fact to be non-controversial expect with people with a religious agenda. Your efforts -- and indeed, the efforts of the entire Creationist community -- are as effective as trying to demolish Mount Everest with a spoon.

      By the way, not too long ago, people like you were poo-pooing the idea that there were billions of other planets in the galaxy. That turned out well...

      Back to the subject in hand. It's way to early to know whether there is a chance life exists on these freshly discovered planets. First we have to detect and analyze the gases in their atmospheres (if any) and then we will have to figure out what we find could have been the byproduct of life as opposed to non-biological chemical processes.

      This is an important discovery, but there is still a long way to go and a lot of hard work ahead for NASA scientists and other astronomers. Meanwhile Creationists will do what they do best -- remain armchair critics.

      "we can't actually make a cell WITH intelligent design"

      FYI We're more than half way there.

      "let alone without it"

      If you provide an Earth sized laboratory and the funds to run it for a few dozen million years, then you can be pretty sure lots of those cells will be created, and without any Intelligent Design involved.

      "Then we have the problem of how error correcting coding in DNA got there by chance"

      In exactly the same way other characteristics of living beings got there, that is, through chance and Evolution. Pre-biotic evolution in this case.

      "please remember that the only field tests of bacterial evolution show that any animal over 4kg will not produce enough beneficial mutations to explain the rapid speciation in the fossil record."

      Citation required, and not a citation from some Creationist hellholeecho room, please. While you are at it, please explain also how the Hell you translate "bacterial evolution over a few decades" into "any animal bigger than 4Kg over millions of years". TY in advance.

    Tidal locking bothers me.

    Those planets must be rather uncomfortable, with one cooked side and one frigid side and craaazy winds.

    We keep finding earth-sized planets in the goldilocks zone around various dwarf stars but they are necessarily always close to their star and therefore tidally locked. I think our best chance of finding alien life will be on planets orbiting larger stars, so that the planets are orbiting far enough out to be spinning. Unfortunately those ones are not so easy to spot.

    1. tacitust

      Re: Tidal locking bothers me.

      If the planets in the goldlocks zone are rich in water, (and simulations indicate that may be the case for many planets orbiting red dwarf stars) there is a chance life could have evolved deep underwater close to fumaroles similar to those found on Earth. Such life might not be detectable, however.

      A point in favor of red dwarfs is their sheer abundance - there are more of them than Sun-like stars so even if conditions suitable for life are much more rare around them, it's still worth investigating them, especially given the easier observing conditions they provide for the planets orbiting them.

      On the downside, many red dwarfs are flare stars -- though too unstable to be conducive to life, but I don't know the numbers off hand.

    Spectral type?

    Can anyone confirm the spectral type of the primary? Only source I've been able to find is Wikipedia, which claims it's an M8, whereas the Reg article says 'white dwarf' which is emphatically NOT the same thing (a white dwarf is a very hot white small star, whilst an M8 is a very cool red dwarf star). The spectral type could have quite an effect on the potential habitability. I'm presuming that because NASA is depicting an orangey looking star that Wikipedia is right on this one, anyone know for sure if that's so?

    1. LDS Silver badge

      Re: Spectral type?

      You're right, but you should use the link to send corrections. Moreover a white dwarf is what happens after the red giant phase, and any planet orbiting the star within hundreds of UA will get a very rough treatment when the star expands..

      1. Esme

        Re: Spectral type?

        @LDS - I wasn't sending a correction, m'dear, just asking for clarification, because I know that Wikipedia isn't an entirely reliable source of information, and I couldn't offhand recall whether there were any white dwarves within 40LY of Sol.
