  • The 9:1 Battle for Time: The Operational Framework and the Dual-Anonymous System that Selects the Universe’s Next Great Discoveries

    Summary, Step-by-Step Guide to JWST Proposal Success, and Comprehensive Proposal Checklist The James Webb Space Telescope (JWST) was designed with multiple, complementary access policies—primarily the General Observer (GO) program (open competition), the Guaranteed Time Observations (GTO) (rewarding instrument developers with about 16% of the first three cycles), and Director’s Discretionary Time (DDT) (reserved for time-critical…

  • HL Tau Protoplanetary Disk Contains More Water Than Earth

    The observations show that there is at least three times more water in the inner disc of the young Sun-like star HL Tauri than in all of Earth’s oceans combined. HL Tau also called HL Tauri is a young T Tauri star located approximately 450 light-years away from earth in the Taurus Molecular Cloud. It…

  • Infant Star SAO 206462 With Protoplanetary Disk 440 Lightyears From Earth

    SAO 206462 (also known as HD 135344B) is a young Herbig F star in the constellation Lupus with a prominent circumstellar protoplanetary disk. The Subaru Telescope captured remarkable images of this system, revealing never-before-seen details of a solar system in the making: 4. Recent high-resolution observations from the James Webb Space Telescope have captured detailed…
