From :- Sky & Telescope By: J. Kelly Beatty Edited by: Amal Udawatta During the last months of 2025, Saturn and the star Fomalhaut are the only two easy-to-spot objects in a southern sky full of faint constellations (as seen from mid-northern latitudes). Sky & Telescope Bottom of Form In this month’s Sky Tour astronomy podcast, we’ll watch two sets of shooting stars, spot some bright planets, point out a few late-autumn constellations, and put a spotlight on five interesting stars. November is the month when those of us in the U.S. and Canada adjust our clocks to “fall back” an hour to standard time. That takes place before dawn on November 2nd in the U.S. and Canada, a week later than it does for our friends in Europe. Mexico and tropical countries don’t make the change at all, nor do China or Russia. The return to standard time means that most of us are still heading home from work as evening’s twilight sets in. That’s just fine, though, ...
Scientists use James Webb Space Telescope to make 1st 3D map of exoplanet — and it's so hot, it rips apart water
From - Space,com , By Stefanie Waldek Edited by Amal Udawatta An artist's representation of WASP-18b, an exoplanet some 400 light-years from Earth. (Image credit: NASA/JPL-Caltech (K. Miller/IPAC)) Astronomers have produced the first-ever three-dimensional map of a planet outside our solar system — WASP-18b — marking a major leap forward in exoplanet research. Using the James Webb Space Telescope , researchers applied a new technique called 3D eclipse mapping, or spectroscopic eclipse mapping, to track subtle changes in various light wavelengths as WASP-18b moved behind its star . These variations allowed scientists to reconstruct temperature across latitudes, longitudes and altitudes, revealing distinct temperature zones throughout the planet's atmosphere. "If you build a map at a wavelength that water absorbs, you'll see the water deck in the atmosphere, whereas a wavelength that water does not ab...
