Listed on Forbes "30 under 30" for Science in 2017, Michelle Kunimoto has discovered 17 new, extra-solar planets.
Astronomy student discovers 17 new planets, including Earth-sized world:
University of British Columbia astronomy student Michelle Kunimoto has discovered 17 new planets, including a potentially habitable, Earth-sized world, by combing through data gathered by NASA's Kepler mission.
Over its original four-year mission, the Kepler satellite looked for planets, especially those that lie in the "Habitable Zones" of their stars, where liquid water could exist on a rocky planet's surface.
The new findings, published in The Astronomical Journal, include one such particularly rare planet. Officially named KIC-7340288 b, the planet discovered by Kunimoto is just 1 ½ times the size of Earth—small enough to be considered rocky, instead of gaseous like the giant planets of the Solar System—and in the habitable zone of its star.
"This planet is about a thousand light years away, so we're not getting there anytime soon!" said Kunimoto, a Ph.D. candidate in the department of physics and astronomy. "But this is a really exciting find, since there have only been 15 small, confirmed planets in the Habitable Zone found in Kepler data so far."
The planet has a year that is 142 ½ days long, orbiting its star at 0.444 Astronomical Units (AU, the distance between Earth and our Sun) - just bigger than Mercury's orbit in our Solar System, and gets about a third of the light Earth gets from the Sun.
Of the other 16 new planets discovered, the smallest is only two-thirds the size of Earth—one of the smallest planets to be found with Kepler so far. The rest range in size up to eight times the size of Earth.

Well, it's nice to see more planets being squeezed out of the Kepler data. Finding one 2/3 the size of Earth is also nice.
Too bad there's no JWST or ATLAST/LUVOIR to give them a look.

Maybe in a year or two for JWST (fingers crossed). I'm not holding my breath for LUVOIR, nor am I even sure it's responsible for the astronomical community (of which I'm party) to propose such an obscenely expensive project. But some people say that bigger projects secure larger budgets (rather than the other way around) -- so, who knows?!
