Specifically, a trio of two white dwarf stars and a collapsed neutron star demonstrated the concept of freefall, according to research published this month in the journal Astronomy and Astrophysics. That’s the idea, famously illustrated by Galileo’s Leaning Tower of Pisa thought experiment, that gravity

The image shows the Soyuz MS-15 spaceflight taking three people to the ISS: Roscosmos cosmonaut Oleg Skripochka and NASA astronaut Jessica Meir as part
