The discovery highlights a powerful new way to find planets in dusty star systems and expands the science return from Webb exoplanet observations. Atmospheric retention ranks rocky planets - A new exoplanet habitability model focuses on whether rocky worlds can hold onto their atmospheres over geologic timescales, giving researchers a better way to rank promising targets. By adding atmospheric survival to the usual habitable zone logic, scientists can better narrow the search for potentially life-friendly planets beyond Earth. Webb captures ancient galaxy cluster - The James Webb Space Telescope has captured a striking view of galaxy cluster MACS J0553.4-3342, showing it as it appeared 4.4 billion years ago. The image offers both a dramatic look-back-time snapshot and valuable data on how massive galaxy clusters form and evolve. Mercury ends apparent retrograde motion - Mercury has reached a stationary point in the sky, ending its apparent retrograde motion and beginning to move eastward again against the background stars. The event is a useful reminder that retrograde is a line-of-sight effect caused by orbital mot…
