It began as a list of a thousand women speakers that I compiled inafter a debate on an atheist forum in which I was arguing for a better gender balance in speakers at such events.
Given that, it might — might — be Earthlike. This is pretty cool news. And it gets niftier: Now let me be clear: Reading the journal paper PDFthough, the data look pretty good.
By coincidence, it appears ot be about the age as the Sun, too: This is an extremely sensitive instrument that looks for changes in the starlight as a planet or planets orbits a star. The gravity of the star causes the planet to orbit it, but the planet has gravity too.
As it circles the star, the star makes a littler circle too I like to think of it as two kids, one bigger than the other, clasping hands and swinging each other around; the lighter kid makes a big circle and the bigger kid makes a smaller circle.
|- The Washington Post||Renowned scientists and experts from several organizations, including NASA, will share information about current research and what it has revealed. The conference includes four programming tracks that will appeal to everyone from the science community to science and sci-fi fans that want to learn more about our universe and our planet.|
This means its light is Doppler shiftedthe same effect that makes a motorcycle engine drop in pitch as it passes you. But in the end, by measuring just how the star is Doppler shifted, you can get the mass and orbital period of the planet.
But the data are public, so a team of astronomers grabbed it and used a more sensitive method to extract any planetary signatures from the data.
They found the three previously-seen planets easily enough, but also found three more! One of them is from a planet that has at least seven times the mass of the Earth, and orbits with a day period. It might be dense and only a little bigger than Earth, or it could be big and puffy.
The star is fainter and cooler than the Sun, remember. Water is common on Earth, and here we are. And that means liquid water. Note the scales are a bit different, so that the habitable zones of the Sun and of HD line up better remember, HD g is actually closer to its star than Earth is to the Sun — an AU is the distance of the Earth to the Sun, so HD is about 0.
What makes me smile is that the new planet is actually better situated in its "Goldilocks Zone" than Earth is! And take a look at the system: Kornmesser ; Tuomi et al.Ouellette topic. Ouellette is a name of French origin common among French Canadians.
