Webb Telescope’s Back-plane arrived at Joint Base Andrews on Monday, August 24, 2015 aboard a U.S. Air Force C-5 cargo plane. The Back-plane, inside the Space Telescope Transporter for Air Road and Sea (STTARS) container, is off-loaded from the C-5 and carefully transported to NASA Goddard Space Flight Center. There the container is moved into the clean room and opened in preparation for the removal of the Back-plane.
The Webb Telescope’s Back-plane is a large composite structure that holds and supports Webb’s hexagonal mirrors. The back-plane supports the weight of the 21-foot (6.5 m) diameter mirror, and 7,500 lbs (2400 kg) of telescope optics and instruments.
The Galaxy and Mass Assembly catalog is a detailed map of the Universe showing where galaxies are in 3D. This simulated fly-through shows the real positions and images of the galaxies that have been mapped so far. Distances are to scale, but the galaxy images have been enlarged for your viewing pleasure.
Will the Sun destroy us one day?
What happens with a giant solar outburst on the scale of the Great Solar Storm of 1859 hits the Earth. Solar scientists got a taste of such a blast in 2012 when the Sun erupted in a giant coronal mass ejection. In one of the largest solar computer simulations ever performed, scientists tracked the impact of a massive wave of solar plasma as it slammed into Earth.
The weakness of gravity compared to the other subatomic forces is a real mystery. While nobody knows the answer, one credible solution is that gravity has access to more spatial dimensions than the other three known forces. In this video, Fermilab’s Dr. Don Lincoln describes this idea, with the help of some very urbane characters.
