Astronomers using the James Webb Space Telescope have captured breathtakingly detailed images of two giant exoplanets orbiting a distant sun-like star. These observations revealed sand-like silicate...
Planets may begin forming much earlier than scientists once believed during the final stages of a star s birth, not afterward. This bold new model, backed...
Tracing the origin of an ultra-hot exoplanet: The chemical composition of WASP-121b suggests that it formed in a cool zone of its natal disc, comparable to...
Scientists may have solved the mystery of why the moon shows ancient signs of magnetism although it has no magnetic field today. An impact, such as...
The puzzling behavior of Titan's atmosphere has been revealed. The team has shown that the thick, hazy atmosphere of Saturn's largest moon doesn't spin in line...
Apples-to-apples comparisons in the distant universe are hard to come by. Whether the subject is dwarf galaxies, supermassive black holes, or 'hot Jupiters,' astronomers can spend...
The NASA New Horizons spacecraft's extensive observations of Lyman-alpha emissions have resulted in the first-ever map from the galaxy at this important ultraviolet wavelength, providing a...
Astronomers have found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars. This is the first time we...
Why do comets and their meteoroid streams weave in and out of Earth's orbit and their orbits disperse over time? Researchers show that this is not...
The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system in HR 8799, a multiplanet...
