The search for life beyond Earth is a key driver of modern astronomy and planetary science. The U.S. is building multiple major telescopes and planetary probes to advance this search. However, the ...

Astronomers have uncovered a unique exoplanet system, revealing a surprising and rare pattern among its planets. The discovery, detailed in a research paper published on the arXiv pre-print server, ...

Astronomers have developed the most realistic model to date of planet formation in binary star systems. The researchers, from the University of Cambridge and the Max Planck Institute for ...

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 by simulations from researchers at SwRI, ...

A Sun-type star situated nearly 3,000 light-years from Earth has provided astronomers with a unique opportunity to observe an ...

An unusual planetary system with three known ultra-low density 'super-puff' planets has at least one more planet, according to new observations. An unusual planetary system with three known ultra-low ...

A decade of observations of four planets around the young planetary system V1298 Tau revealed a rare, long-sought missing ...

Artist impression of the four classes of planetary system architecture. A new architecture framework allows researchers to study an entire planetary system at the systems level. If the small planets ...

An international team of researchers has just revealed the existence of three Earth-sized planets in the binary stellar system TOI-2267 located about 190 light-years away. This discovery, published in ...

Illustration comparing the planets of the Solar System and the Sun on the same scale. The planets are shown to scale relative to each other but their distances are not. From left to right the bodies ...
