5 days ago · Extrasolar planet, any planetary body that is outside the solar system and that usually orbits a star other than the Sun. Extrasolar planets were first discovered in 1992. More than 5,000 are known, and almost 9,000 await further confirmation. Learn more about extrasolar planets in this article.

4 days ago · Cassini–Huygens ( / kəˈsiːni ˈhɔɪɡənz / kə-SEE-nee HOY-gənz ), commonly called Cassini, was a space-research mission by NASA, the European Space Agency (ESA), and the Italian Space Agency (ASI) to send a space probe to study the planet Saturn and its system, including its rings and natural satellites.
3 days ago · The surface of Titan, Saturn’s icy moon, is believed to be composed of various molecular minerals with a great diversity in structure and composition. Under the surface conditions, 93 K and 1.45 atm, most small molecules solidify and form minerals, including acetylene and ammonia. These two compounds can not only form single-component solids but also a 1:1 binary cocrystal that exhibits ...

[ NAOJ, CC BY 4.0] The galaxy RX J2129–z8He II is remarkable for its high redshift, sloped spectrum, and strong emission lines. New research suggests that the elusive first stars could be responsible for the galaxy’s ...

4 days ago · Description. This was an uncrewed test flight of the Saturn 1 (SA-3) booster. The Saturn 1st stage carried upper stages filled with 23,000 gallons of water on a sub-orbital flight to a peak altitude of 167 km, 4 minutes 53 seconds after launch.
6 days ago · Here, the novel technique of extended-range high-energy-resolution fluorescence detection (XR-HERFD) has successfully observed the n = 2 satellite in manganese to a high accuracy. The significance of the satellite signature presented is many hundreds of standard errors and well beyond typical discovery levels of three to six standard errors. This satellite is a sensitive indicator for all ...
