Moon water discovered for the first time from the lunar surface

A Chinese lunar lander Chang'E-5 used an onboard instrument to take measurements from the surface of the moon to find traces of water, something previously only done from Earth or orbit. Its findings were published in a study last week, raising more questions on how water is formed and staying on the moon. ....

Manmade Satellites Cause Light Pollution in Night Sky, Study Finds


Manmade Satellites Cause Light Pollution in Night Sky, Study Finds
Those days may be behind us now.
Satellite companies are rushing to launch small satellites into low orbits of Earth to provide fast internet access to remote places. These satellites form artificial mega-constellations that are quickly changing the night sky.
For instance, Elon Musk’s SpaceX has launched around 1,300 small satellites into space as part of its Starlink internet service, and SpaceX has already gotten permission to launch 12,000 of them. Now, even in the darkest places on Earth, the night sky is contaminated by the trajectories of these small satellites, which can sometimes be seen with the naked eye. ....

Starlink satellites create bright lines through an observatory’s view of the night sky.
If you travel to one of the darkest places on Earth, you can see one of the last great things completely unaltered by humans: the entire night sky.
But increasingly, even in the darkest places on Earth (which are vanishingly rare themselves), humankind is beginning to interfere with this primordial view. The unimpeded view of the night sky is being lost, and quickly.
In their quest to provide global broadband internet access to remote places, satellite companies are launching small constellation satellites into orbit close to the Earth so that the internet connection doesn’t have too long of a delay. ....

Elon Musk's Starlink satellites are still too bright
