Speaker: Prof. Darryl Stanford

Tonight SMCAS will be treated to a special Fall Planetarium show ‘ ‘The Sky Tonight’ by Astronomy Professor Darryl Stanford. This will be followed by the first showing at CSM of the fulldome movie ‘Unveiling the Invisible Universe‘:

For thousands of years humans observed the light coming from the night sky with their eyes. In the beginning of the 17th century, the invention of the telescope by Galileo revolutionized our knowledge of the Universe. Finally, in the 20th century with the advent of rockets, it became possible to go above the earth’s atmosphere and observe X-ray and gamma ray radiation which are the marks of the hot and violent Universe. But it is not only light that can give us information about the cosmos. Neutrinos and cosmic rays also provide vital information. Finally, the detection by the LIGO experiment of gravitational waves from two merging black holes opened a new window in astrophysics. This video presents images of the cosmos as revealed by all these different messengers.

We propose a mission concept for a space observatory with a large-aperture (50-meter) unsegmented primary mirror suitable for a variety of astronomical applications. The mirror would be created in space via a novel approach based on fluidic shaping in microgravity, which has already been successfully demonstrated in a laboratory neutral buoyancy environment, in parabolic microgravity flights, and aboard the International Space Station (ISS). Theoretically scale-invariant, this technique has produced optical components with superb, sub-nanometer (RMS) surface quality.
