Trojan asteroids are mysterious space rocks that hold clues to the early solar system. Special | 3m 26sVideo has Closed Captions | CC Back in 2021, Lucy set off to explore some of the oldest and most fascinating objects in our solar system—Trojan asteroids!
Comets didn’t seed life on Earth after all, a new study suggests, potentially overturning a century-old idea. The theory that comets delivered the molecular building blocks for life on Earth is a long-standing one, since comets are known to carry…
A visitor from another star system has just given astronomers a surprise, and it’s hiding in plain sight, frozen inside the comet’s icy grains. The James Webb Space Telescope took a close look, and what it found doesn’t quite match…
The James Webb Space Telescope finds comet 3I/ATLAS's chemistry resembles that of some icy worlds beyond Neptune in our Solar System Astronomers have pointed the James Webb Space Telescope at interstellar comet 3I/ATLAS and made some surprising discoveries about its…
JWST observations of interstellar comet 3I/ATLAS reveal micron-sized, dust-rich water ice grains whose spectra resemble icy bodies beyond Neptune, suggesting planetary building blocks around other stars share a continuum of grain properties with our own solar system.
A comet swept through the solar system carrying a strange chemical recipe — one that has astronomers taking a closer look at what kinds of worlds might form around distant stars. Astronomers studying the interstellar comet 3I/ATLAS detected two gases streaming…
Learn more about the unique ice grains from comet 3I/ATLAS and how they may hold clues to the building blocks of planets. Comet 3I/ATLAS may be heading away from the sun now, but we still have much to learn from…
Earth may have produced much of its water during the planet’s formation, as rocky pebbles reacted with the hydrogen-rich atmosphere surrounding the young planet, according to new research published in Nature Geoscience. The findings offer a potential explanation for how…
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have found that the water ice in the interstellar comet 3I/ATLAS is mixed with dark, rocky material in tiny grains. The grains’ spectral characteristics differ from those of ice grains…
[astro-ph.EP]. High-resolution cross-correlation spectroscopy (HRCCS) is a powerful technique for detecting molecules whose individual spectral lines are too weak to be identified directly, but its sensitivity is limited by the availability and quality of high-resolution opacity data. In this…
Molecules found between the stars, in comets and in planet-forming discs, and the astrochemistry of JWST and ALMA.
