What looks like a vortex of fire is in reality a disc around the young AB Aurigae star.
Close to the centre, the ‘twist’ (in very bright yellow) marks the spot where scientists believe a planet is forming. 🔭

年の瀬ですが、太陽系の果ての天体が星を隠す瞬間の撮影に成功しました！
12月26日(おととい)、国内最大の光学望遠鏡『せいめい望遠鏡』を使用して、カイパーベルト天体(78799) Xewiosoによる恒星掩蔽の観測に世界で初めて成功しました！
円内の恒星が一瞬で隠され見えなくなり、その後出現している様子をご覧ください。

Laser light and the quantum nature of gravity: New concept for energy transfer between gravitational waves and light - Helmholtz-Zentrum Dresden-Rossendorf, HZDR
When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of light and cause tiny distortions in space-time. Albert Einstein predicted the...
