“Here is the video I shot, be prepared to be mind-blown!” Marco Langbroek wrote on his website SatTrackCam Leiden (b)log, where he shared an amazing capture of dozens of SpaceX Starlink internet satellites chugging along, in a straight line, across the heavens.

Does Pluto have an ocean? That idea seems preposterous at first, but a new study adds to the growing evidence for a subsurface ocean on this distant dwarf planet … and explains how it stays liquid.

New research suggests that a wayward dwarf planet collided with the moon in the early history of the solar system, causing the stark difference between the moon’s heavily-cratered far side and the lower-lying open basins of its near side.

Early results from China’s historic 1st landing on the moon’s far side. Chinese scientists have used in situ data from a far side crater to identify materials on the moon’s surface that originated deeper inside the moon.

A new study shows that Mars has a unique water vapor cycle that occurs only once about every 2 years. The cycle might help explain how Mars lost most of its water.

A cosmic collision in action. Read more about what happens when 2 galaxies sideswipe each other.

A new “survival guide for exoplanets” outlines how different kinds of planets fare when their host star dies. It suggests the smallest rocky worlds are the most likely to escape annihilation.

Dwarf planet Haumea orbits in Pluto’s realm of the solar system. It’s the most distant little world known to have a ring. Scientists in Brazil have new insights on how Haumea’s ring maintains its nearly perfect circular shape.

Before we send people to Mars, we need to understand more about how Martian dust could affect astronauts and their equipment. Here are 3 things we’ve learned from the planet’s 2018 global dust storm.

Analysis of data from the Gaia satellite shows a powerful burst of star formation – a stellar baby boom – in our Milky Way galaxy 2 to 3 billion years ago. This single burst might have created half the stars in the galaxy’s flat disk.

The moon’s south pole has never been explored from the ground, but India’s new Chandrayaan-2 mission will attempt a 1st-ever landing there, with a rover, this September.
