These two celestial bodies share a heartbeat, puzzling scientists

About 15,000 light-years away from Earth, a cloudy patch of space within our galaxy produces ultra-bright flashes of gamma radiation like clockwork. That’s not all—researchers found the unusual “heartbeat” coming from this cosmic gas cloud is beating along in time with the pulses of a black hole, located a whopping 100 light-years away from it. Researchers remain puzzled as to what the unusual long-distance relationship is between the two.

Gaze in Awe at Hubble’s Most Detailed View of the Triangulum Galaxy

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

Artificial Intelligence, NASA Data Used to Discover Eighth Planet Circling Distant Star

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

Scientists Discover Long-Sought Evidence of First Stars Forming

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

Remarkable Image Captures Surface Details of a Dying Star Located 530 Light-Years Away

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.
