Vibration Testing of NASA’s James Webb Space Telescope

Inside NASA’s Goddard Space Flight Center in Greenbelt, Maryland the James Webb Space Telescope team completed the environmental portion of vibration testing on the telescope. A shaker table is used to shake satellites to ensure a spacecraft like Webb can withstand the shaking that comes with a ride into space on a rocket. The new vibration test system simulates the forces the telescope will feel during the launch by vibrating it from 5 to 100 times per second.

The Universe’s First Molecule Is Found at Last

Scientists on the airborne observatory SOFIA detected the first type of molecule that ever formed in the universe. They found the combination of helium and hydrogen, called helium hydride, in a planetary nebula near the constellation Cygnus. This discovery confirms a key part of our basic understanding of the early universe and how it evolved over billions of years into the complex chemistry of today.
