The Venus Transit and Hunting For Alien Worlds

Posted by Soulskill on from the pretty-pictures-and-awesome-science dept.

astroengine writes "Forget simply detecting a slight 'dip' in brightness as an exoplanet transits in front of its star; soon we'll be able to image the event. What's more, by doing this we'll see that exoplanetary transits look exactly like the historic Venus transit that wowed the world on Tuesday. This is according to astronomer Gerard van Belle, of Lowell Observatory near Flagstaff, Ariz., who hopes to use an interferometer to carry out the mind-blowing goal of capturing the silhouettes of exoplanets drifting in front of distant stars. But that's not all: this whole effort may help us track down the first bona fide Earth-like alien world." In case you missed it, NASA posted a bunch of great footage and pictures of the Venus transit, as did Boston.com's The Big Picture. Phil Plait pointed out a cool shot from Thierry Legault of a transit during a transit.

    If you have to use gimmicks like:
    • Starting your summary with "Forget... Soon we'll be able to..."
    • Using phrases like "wowed" and "mind-blowing"
    • Closing with "but that's not all"

    It's generally a warning to readers that either there is no substance to what you're going to tell us, or we're about to hear the breathlessly-excited gossip of a 13-year old.

    Try to stick to concisely telling us the facts, and let the story is be impressive on its own merits.

  2. I was talking to a friend of mine about the transi by tlambert · · Score: 4, Interesting

    Moderately off topic...

    My friend was very upset that she did not get to see it in person.

    It seems a lot of newsspeak organizations were quoting "experts" that "there will be plenty of people with setups to view it", and that "the apparatus to view it is dead simple". But she didn't get to see it /directly/ because there were not sufficiently scientifically inclined people set up in her area to let her see it.

    All it required a small amount of optics (binoculars), a mirror, and something to project the image onto. Getting to this point was beyond her, and it was beyond the people she worked with. It really drives home to me how disconnected science programs in schools are from cause/effect in reality.

    It makes me wonder how much stuff that is "obvious" to us just doesn't filter down into the impact it makes on humans everyday lives.

    This reminds me very much of a discussion I had with someone about "the theory of evolution" when I pointed out that dropping an object was a demonstration of "the theory of gravity". She was appalled that gravity was considered a theory from a scientific point of view -- "You mean you don't know how this stuff works?!?"; I had to explain that yes, we knew *how* it worked, we just didn't know *why* -- the same as evolution.

    The idea that people can do science (maybe Science, with a capitol 'S'?) with stuff they have lying around their house is probably not emphasized enough; it made me want to become a science teacher, but of course I'm not qualified, only being a physicist and a computer scientist, and not havig a degree in education, or being a member of a teachers union.

    Makes me worry about the future more than I already do.
