When you title a research paper “In Search for a Planet Better than Earth,” you’re not messing around. Earth, the only place we know for sure hosts life, sets a high bar for all other planets.
Discovering a new star is always a delight in astronomy. So you can probably imagine the excitement over discovering a giant stream of stars winding through the Milky Way. Continue reading Astronomers found a stream of thousands of stars hiding in the Milky Way
Usually when astronomers talk about our neighboring galaxy, they’re talking about Andromeda, which is a cozy 2.5 million light-years away. But just a little farther—okay, 500,000 light-years farther—is another spiral galaxy, the third largest in our local group. Hubble has just released its most detailed view yet of that galaxy, which is known as Triangulum (can you see why?). Continue reading Gaze in Awe at Hubble’s Most Detailed View of the Triangulum Galaxy
Our solar system now is tied for most number of planets around a single star, with the recent discovery of an eighth planet circling Kepler-90, a Sun-like star 2,545 light-years from Earth. The planet was discovered in data from NASA’s Kepler Space Telescope. Continue reading Artificial Intelligence, NASA Data Used to Discover Eighth Planet Circling Distant Star
When you sweep across the FM radio band, you don’t always hear music—mostly, you hear static. Lots of this ambient noise is actually garbled signals from throughout the Milky Way. If you had perhaps the most sensitive FM receiver on Earth, you might pick up the tiniest dip in volume: a signal that comes not from our galaxy, but from the earliest stars in the Universe. Continue reading Scientists Discover Long-Sought Evidence of First Stars Forming
By combining the power of four telescopes, an international team of astronomers has captured the most detailed image yet of a distant star—an observation that’s meshing well with pre-existing theories about the physical characteristics of giant stars.
