Using the wide-field survey capabilities of the Subaru Telescope, astronomers discovered active supermassive black holes, or quasars, in the distant universe and then studied them with the James Webb Space Telescope (JWST). This work has revealed how galaxies and their central black holes grew 12.9 billion years ago.

The official number of exoplanets—planets outside our solar system—tracked by NASA has reached 6,000. Confirmed planets are added to the count on a rolling basis by scientists from around the world, so no single planet is considered the 6,000th entry. The number is monitored by NASA’s Exoplanet Science Institute (NExScI), based at Caltech’s IPAC in […]

The iron-rich core at the center of our planet has been a crucial part of Earth’s evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, it also influences plate tectonics which have continually reshaped the continents.

A collaborative team has revealed new observational evidence that sheds light on the mystery of massive star formation. Researchers from Yunnan University, the Shanghai Astronomical Observatory of the Chinese Academy of Sciences, and the University of Chile, along with other domestic and international institutions, have published their findings in The Astrophysical Journal Supplement Series.
