'Starquakes' shake the surface of thousands of stars, Gaia galaxy mapper reveals
"Blinking stars do offer astronomers a very powerful tool to study their internal physics and chemistry."
The galaxy-mapping mission Gaia has detected thousands of stellar earthquakes
The discovery is rather surprising as the spacecraft was not designed to do such work,
The stellar earthquakes were discovered in a subset of observations focusing on the distribution of variable stars in the Milky Way galaxy,
The June 13 Gaia data release also contains the largest ever compiled data set of binary star systems in our galaxy,
"We can also detect some really interesting things like stars that have neutron stars or black holes as companions."
This new data set contains 40 times more binary star systems than have been previously known and studied
