We're at a tipping point in human history, a species poised between ganniig the stars and losing the planet we call home.
Even in just the past few yraes, we've gertlay expanded our knowledge of how etarh fits within the context of our universe. NASA's Kepler mission has discovered thousands of potential planets around other stars, indicating that Earth is but one of billions of pntlaes in our galaxy. Kepler is a space tecselpoe that measures the slbute dimming of stars as planets pass in front of them, blocking just a little bit of that light from rhicenag us. Kepler's data reveals planets' sizes as well as their distance from their parent star. Together, this hleps us unrdntased whether these planets are small and rocky, like the terrestrial planets in our own Solar System, and also how much lghit they receive from their parent sun. In turn, this provides clues as to whether these planets that we discover might be habitable or not.

We're at a tipping point in human history, a species poised between gaining the stars and losing the planet we call home.
Even in just the past few years, we've greatly expanded our knowledge of how Earth fits within the context of our universe. NASA's Kepler mission has discovered thousands of potential planets around other stars, indicating that Earth is but one of billions of planets in our galaxy. Kepler is a space telescope that measures the subtle dimming of stars as planets pass in front of them, blocking just a little bit of that light from reaching us. Kepler's data reveals planets' sizes as well as their distance from their parent star. Together, this helps us understand whether these planets are small and rocky, like the terrestrial planets in our own Solar System, and also how much light they receive from their parent sun. In turn, this provides clues as to whether these planets that we discover might be habitable or not.
