McDonald Observatory astronomers working with NASA’s Kepler mission have helped to discover the first near-Earth-sized planet around a Sun-like star in the “habitable zone,” the range of distances where liquid water could pool on a planet’s surface.
The Giant Magellan Telescope's 11 international partners, including UT Austin, have unanimously approved its construction, securing the future of the project with more than $500 million to begin work on the world’s most powerful optical telescope. GMT is expected to see first light in 2021.
Countless lights fill the night sky, from stars and planets to airplanes and weather balloons. One of the brightest is the International Space Station, which is sometimes visible in the deep twilight before sunrise or after sunset.
