‘Lobster eye’ in space promises new look at x-rays
China last week launched an x-ray observatory with an unusual telescope inspired by the structure of lobster eyes to gather new data on gamma ray bursts, supernovae, and stars being swallowed by black holes. The Einstein Probe (illustration above)—a joint project of the Chinese Academy of Sciences, the European Space Agency, and the Max Planck Institute for Extraterrestrial Physics—will also capture x-rays from violent events that generate gravitational waves, such as two neutron stars colliding. The telescope features a survey instrument, modeled on a lobster’s eye, with microscopic square tubes that can funnel x-rays from many directions to a single detector—the first time the approach has been incorporated into a major telescope. The instrument can survey the entire night sky in less than 5 hours, allowing it to discover transient x-ray–emitting sources and alert astronomers for follow-up observations.
