  Washington (AFP) May 29, 2019 It looked like a scene from a sci-fi blockbuster: an astronomer in the Netherlands captured footage of a train of brightly-lit SpaceX satellites ascending through the night sky this weekend, stunning space enthusiasts across the globe. But the sight has also provoked an outcry among astronomers who say the constellation, which so far consists of 60 broadband-beaming satellites but could one day grow to as many as 12,000, may threaten our view of the cosmos and deal a blow to scientific discovery. ... read more |

 Glasgow UK (The Conversation) May 27, 2019 
In the Chinese science fiction film The Wandering Earth, recently released on Netflix, humanity attempts to change the Earth's orbit using enormous thrusters in order to escape the expanding sun - and prevent a collision with Jupiter.
The scenario may one day come true. In five billion years, the sun will run out of fuel and expand, most likely engulfing the Earth. A more immediate threat ... more |

With less than a fifth of the Moon's mass, Pluto can still retain an atmosphere, though a tenuous envelope of gas produced by the periodical sublimation of nitrogen ices. A study that followed the evolution of Pluto's atmosphere for fourteen years shows its seasonal nature, and predicts that it will now start to condensate as frost.
This study1 was published in the journal Astronomy and As ... more |

The mystery of why Earth has so much water, allowing our "blue marble" to support an astounding array of life, is clearer with new research into comets. Comets are like snowballs of rock, dust, ice, and other frozen chemicals that vaporize as they get closer to the Sun, producing the tails seen in images.
A new study reveals that the water in many comets may share a common origin with Eart ... more |
