The presence of deuterium, an isotope of hydrogen, in 3I/ATLAS suggests the interstellar comet formed in a much colder place ...

An interstellar comet carries water unlike anything in our solar system, revealing a far colder birthplace and clues about ...

New research confirms Earth formed almost entirely from material in the inner Solar System, with Jupiter acting as a barrier to outer Solar System debris. Isotopic analysis of meteorites shows a close ...

New observations of interstellar comet 3I/ATLAS show high levels of deuterated water, suggesting it formed in a colder star ...

New work from Carnegie’s Alan Boss and Sandra Keiser provides surprising new details about the trigger that may have started the earliest phases of planet formation in our solar system. It is ...

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 system 130 light-years away that has long been a ...

Meteorite isotope research shows Earth's composition aligns almost entirely with inner solar system materials, with Jupiter's gravity likely blocking outer solar system debris. Published in Nature ...

An image from the ALMA telescope array in Chile shows jets of silicon monoxide blowing away from the young star HOPS-315. The blue jet is moving towards Earth, and the red jet is moving away from us.
