Hubblecast 77: Hubble and the Bermuda Triangle of space
This Hubblecast tells the story of what happens to Hubble in the mysterious region known as the South Atlantic Anomaly. When satellites pass through this area they are bombarded with swarms of intensely high energy particles. This can produce “glitches” in astronomical data, malfunctioning of on-board electronics, and has even shut down unprepared spacecraft for weeks!

The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA’s Goddard Space Flight Center manages the telescope. The Space Telescope Science Institute (STScI), is a free-standing science center, located on the campus of The Johns Hopkins University and operated by the Association of Universities for Research in Astronomy (AURA) for NASA, conducts Hubble science operations.
