- This just in! Turns out it wasn’t just dust on the telescope lens: NASA just announced the discovery of seven earth-size planets orbiting the same star only 235 trillion miles away. In space terms, that practically makes us next-door neighbors! What exactly does this new solar system TRAPPIST-1 mean for our universe? Well, three of these newly discovered planets land smack-dab in the middle of what scientists call the habitable zone, or the distance from the star it orbits “where a rocky planet is most likely to have liquid water.” Though scientists have some serious studying to do before we can definitively say whether any of the new TRAPPIST-1 planets are habitable, the potential is very promising. So if three of these new TRAPPIST-1 planets land in the habitable zone, what about the other four? According to NASA, all seven planets could have liquid water, the most crucial ingredient for life -- assuming the right atmospheric conditions. Unlike our solar system, the planets in TRAPPIST-1 are very close together. If we’re able to visit one of the TRAPPIST-1 planets one day, we could be able to watch each neighboring planet pass by on its orbital journey! Until then, you can explore TRAPPIST-1 d, the third planet in the TRAPPIST-1 solar system in 3D using your computer or mobile device. If you have a virtual reality device, you can also take a stroll around. Happy solar-searching! We don’t know about you, but we’re hoping to spend our next vacation luxuriating by the cosmic pool. At least that's where you'll find Nate Swinehart, the artist for today's star-studded Doodle.
