This is a NASA Hubble Space Telescope near-infrared-light image of a three-light-year-tall pillar of gas and dust that is being eaten away by the brilliant light from nearby stars in the tempestuous stellar nursery called the Carina Nebula, located 7,500 light-years away in the southern constellation Carina. The image marks the 20th anniversary of Hubble’s launch and deployment into an orbit around Earth.
The image reveals a plethora of stars behind the gaseous veil of the nebula’s wall of hydrogen, laced with dust. The foreground pillar becomes semi-transparent because infrared light from background stars penetrates through much of the dust. A few stars inside the pillar also become visible. The false colors are assigned to three different infrared wavelength ranges. Hubble’s Wide Field Camera 3 observed the pillar in February and March 2010. Object Names: HH 901, HH 902 Image Type: Astronomical

Super Kamiokande is one of only a few neutrino observatories in the world. It is located a kilometre underneath the Kamioka mountain in Japan and consists of a cylindrical steel tank, about 40m in diameter, filled with 50,000 tons of ultra-pure water and lined with 11,146 hand blown glass photomultiplier tubes.

This huge but delicate device has been built to try and catch a glimpse of the countless neutrinos that travel through the Earth every moment – 50 trillion neutrinos are passing through your body every second. This strange, elementary particle has mass, travels close to the speed of light, yet can pass through matter almost unnoticed.
