Yesterday, when it was morning in the Pacific Ocean, the Space Telescope NuStar (Nuclear Spectroscopic Telescope Array) was launched and successfully entered orbit. NuStar will use a Wolter telescope, a telescope for high energy X-rays (6 to 79 keV) using grazing incidence optics. This is because X-rays can be deflected and focused only with small angles, unlike visible light.

Enceladus, one of Saturn’s moons, has been studied in recent years by the Cassini space probe. Recently it was talked about for the extraordinary jets of water and ice that rise up from the south polar region of Enceladus, because Cassini detected organic materials. The scientists, however, also focused their attention on dusty plasma, a condition observed for the first time, that those jets contain.
