Using advanced new simulations, a team of astronomers in the U.S. has developed a promising new theory for how giant, gaseous exoplanets migrate into stiflingly close orbits around their host stars. Led by J. J. Zanazzi at ...
Scientists may add a new dwarf planet to the official roster of our solar system. The distant, icy body, provisionally dubbed 2026 ED138, orbits our system beyond Pluto. It was spotted earlier this month by a scientist combing ...
A Southwest Research Institute–led study used NASA's James Webb Space Telescope to examine ice grains streaming from interstellar comet 3I/ATLAS, just the third object from beyond our solar system ever identified. The observations ...
Water isn't always as it seems. Under extreme conditions, such as those found on other planets, it has been discovered to change its atomic structure, giving it the means to alter its appearance and other properties.
By indirectly probing the depths of Uranus and Neptune's atmospheres, an international team of scientists has revealed a significant contrast in their chemical composition. Neptune appears to be more enriched in oxygen than ...
The fate of our solar system is written in the stars—well, one star to be precise: the sun. Estimates of what the end will look like once the sun sheds much of its mass and ultimately dies vary widely. New research published ...
The only known supernova remnant of its kind in the Milky Way has an unexpectedly intricate structure: chains of gas knots resembling pearls on a string, each wide enough to fit the solar system multiple times. Using the ...
This summer, exoplanet science—the study of planets orbiting stars beyond our sun—took a big step forward. Reports of helium gas escaping from the atmosphere of LHS 1140b propelled this exoplanet from the pages of scientific ...
In recent decades, astronomers have reconstructed a fairly complete scenario for planet formation, from minute dust motes clumping together to the emergence of rocky spheres thousands of kilometers across, like Earth, or ...
A star and its planets form when a cloud of gas and dust collapses in on itself somewhere in space. The cloud then forms a disk around the nascent star, within which the planets will form. This protostar and its disk then ...
