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 ...

Cloud Seeding For Snow Scientists Report First Quantifiable Observations
2018/2/1
For the first time, scientists have obtained direct, quantifiable observations of cloud seeding for increased snowfall -- from the growth of ice crystals, through the processes that occur in clouds, t...
