Older than expected: artist’s impression of a magnetar in a cluster of ancient stars (in red) close to the spiral galaxy M81. The source of fast radio bursts (FRBs) first detected in 2020 is likely to be located within a dense cluster of ancient stars, according to astronomers led by Franz Kirsten at Chalmers University

WASHINGTON — European Space Agency officials said prospects are dimming for the recovery of a radar imaging satellite that malfunctioned nearly three months ago, but that efforts to save the spacecraft continue. The Sentinel-1B spacecraft malfunctioned in December, keeping the spacecraft from collecting C-band synthetic aperture radar (SAR) imagery. ESA said in January that they
