Record-breaking gamma-ray burst lasts more than seven hours, challenging existing explanations

Infrared and optical observations from NOIRLab and Gemini observatories indicate a relativistic jet formed in an extremely dense and dusty environment in a massive galaxy

NASA Examines Technology Demonstration to Raise Swift Space Telescope Orbit

The telescope, which has been in space for over 20 years, could burn up in the atmosphere if its orbit is not raised. * Design studies are examining an orbit raise that could extend the Swift Space Telescope's operation and advance satellite servicing capabilities.
