Our solar system is a weird place. Much more than a home to eight planets, it’s filled with a myriad of fascinating other smaller bodies, including moons, asteroids, and comets. In recent decades, ...
Astronomers are closing in on one of the most tantalizing possibilities in planetary science, evidence that a previously unknown world may be lurking in the outer reaches of the solar system. The ...
Scientists say a nearby red dwarf star hosts a planetary lineup that looks like a mirror image of our own solar system, with rocky worlds bookending a pair of gas-rich planets. Around the star LHS ...
Even at a glance, the planets in our solar system are wildly diverse. Huge and small, airless and densely packed with ...
The presence of deuterium, an isotope of hydrogen, in 3I/ATLAS suggests the interstellar comet formed in a much colder place ...
Measurements of this interstellar comet’s molecular makeup show an excess of heavy water molecules that is dramatically different from anything known to have ever formed around our sun ...
A new study shows a deep connection between some of the largest, most energetic events in the universe and much smaller, weaker ones powered by our own Sun. The results come from a long observation ...
CAPE CANAVERAL, Fla. — Astronomers have discovered a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside forces since their birth billions of years ...
Stars are thought to form within enormous filaments of molecular gas. Regions where one or more of these filaments meet, known as hubs, are where massive stars form. These massive stars, located ...
Estimating ages of specific events is one of the most difficult problems in astrophysics. While we have a precise (and probably accurate) age for the solar system, we do not have precise ages for each ...
Approximately 4.5 billion years ago, a cold cloud of gas and dust buried deep in one of the Milky Way galaxy’s spiral arms started to collapse. From there, gravity worked its magic. The cloud began to ...
