The Discovery A candidate planet that might be remarkably similar to Earth, HD 137010 b, has one potentially big difference: It could be colder than perpetually frozen Mars. Key Facts Scientists continue to mine data gathered by NASA’s Kepler Space Telescope, retired in 2018, and continue to turn up surprises. A new paper reveals the […]

At the heart of our own galaxy, there is a dense thicket of stars with a supermassive black hole at the very center. NASA’s Nancy Grace Roman Space Telescope will provide the deepest-ever view of this zone, revealing stars, planets, and unique objects that resist definition. Based on the input of astronomers from across the […]

Like a game of cosmic bumper cars, scientists think the early days of our solar system were a time of violent turmoil, with planetesimals, asteroids, and comets smashing together and pelting the Earth, Moon, and the other inner planets with debris.

NASA’s next big eye on the cosmos is now fully assembled. On Nov. 25, technicians joined the inner and outer portions of the Nancy Grace Roman Space Telescope in the largest clean room at the agency’s Goddard Space Flight Center in Greenbelt, Maryland. “Completing the Roman observatory brings us to a defining moment for the […]

The (Proto) Planet:  WISPIT 2b  The Discovery:  Researchers have discovered a young protoplanet called WISPIT 2b embedded in a ring-shaped gap in a disk encircling a young star. While theorists have thought that planets likely exist in these gaps (and possibly even create them), this is the first time that it has actually been observed. […]

The milestone highlights the accelerating rate of discoveries, just over three decades since the first exoplanets were found. The official number of exoplanets — planets outside our solar system — tracked by NASA has reached 6,000. Confirmed planets are added to the count on a rolling basis by scientists from around the world, so no […]
