  • Brightest gamma-ray burst illuminates our galaxy as never before
    on March 28, 2023 at 6:00 pm

    ESA space telescopes have observed the brightest gamma-ray burst ever seen. Data from this rare event could become instrumental in understanding the details of the colossal explosions that create gamma-ray bursts (GRBs).

  • Webb measures the temperature of a rocky exoplanet
    on March 27, 2023 at 3:00 pm

    An international team of researchers has used the NASA/ESA/CSA James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet’s thermal emission: heat energy given off in the form of infrared light detected by Webb’s […]

  • Hubble monitors changing weather and seasons on Jupiter and Uranus
