Hi everyone, I hope you're doing well
NASA recently announced the discovery 7 earth-sized planets in a solar system, with 3 of them in the habitable-zone. (https://www.nasa.gov/press-release/nasa-telescope-reveals-largest-batch-of-earth-size-habitable-zone-planets-around)
There are some pretty interesting properties that have been found so far:
- "At about 40 light-years (235 trillion miles) from Earth, the system of planets is relatively close to us"
- "Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water."
- "In contrast to our sun, the TRAPPIST-1 star – classified as an ultra-cool dwarf – is so cool that liquid water could survive on planets orbiting very close to it, closer than is possible on planets in our solar system."
- "All seven of the TRAPPIST-1 planetary orbits are closer to their host star than Mercury is to our sun."
- "The planets also are very close to each other. If a person was standing on one of the planet’s surface, they could gaze up and potentially see geological features or clouds of neighboring worlds, which would sometimes appear larger than the moon in Earth's sky."
Feel free to also watch this video posted by NASA:

I think it's a really exciting discovery, and I'm keen to find out more about them as the planets get examined more. If it's possible, I'd love to be able to witness a project to send some kind of rover to the planets to see what it's to be on them. With a 40-year delay in communication, I'd imagine it would be difficult to get a truly interactive experience of any of the planets
Having said that, NASA created a 360-video showing what it could be like on the planet:

Feel free to discuss anything you find interesting about the discovery, or about exoplanets in general
