New observations of black hole devouring a star reveal rapid disk formation（图）
New observations black hole devouring star rapid disk formation
2020/9/11
When a star passes too close to a supermassive black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study the ...

SYNOPTIC OBSERVATIONS OF CALVING EVENTS IN ANTARCTICA USING SPACEBORNE IMAGES
Antarctica Calving Optical Images Rifts Icebergs
2019/2/28
Iceberg calving is the detachment of ice from ice shelves or glaciers. Although calving is a natural phenomenon, an abnormal rate of calving can be a threat to ice shelves. Some of the events were so ...
