Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't have hard surfaces. Jupiter and Saturn are the gas giants in our solar system, but there are many ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new extrasolar planet transiting a distant star. The newfound alien world, designated TOI-6692 b, is the size ...
Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.
Dr. Leonardos Gkouvelis, researcher at LMU's University Observatory Munich and member of the ORIGINS Excellence Cluster, has solved a fundamental mathematical problem that had obstructed the interpretation of exoplanet atmospheres ...
An international team including Cornell researcher Jake Turner has developed a novel analysis method capable of uncovering previously undetectable stellar and exoplanetary signals hidden within archival radio-astronomical ...
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 latest: a possible rocky planet slightly larger than Earth, orbiting ...
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, ...
Scientists have discovered over 6,000 planets that orbit stars other than our sun, known as exoplanets. More than half of these planets were discovered thanks to data from NASA's retired Kepler mission and NASA's current ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new extrasolar planet orbiting a sun-like star. The newfound alien world, designated TOI-3862 b, turns out to ...
The early stage of giant telescope development involves a lot of horse-trading to try to appease all the different stakeholders that are hoping to get what they want out of the project, but also to try to appease the financial ...
