Given that annual fluctuations in solar irradiation become less pronounced the closer you get to the equator, it might get less relevant to track time by referring to our position to the sun?

On Saturday NASA astronaut Butch Wilmore noticed some strange noises emanating from a speaker inside the Starliner spacecraft. "I've got a question about Starliner," Wilmore radioed down to Mission Control, at Johnson Space Center in Houston. "There's a strange noise coming through the speaker ... I don't know what's making it." Wilmore said he was not sure if there was some oddity in the connection between the station and the spacecraft causing the noise, or something else. He asked the flight controllers in Houston to see if they could listen to the audio inside the spacecraft. A few minutes later, Mission Control radioed back that they were linked via "hardline" to listen to audio inside Starliner, which has now been docked to the International Space Station for nearly three months.

TL;DR it seems to have exotic short-lived radioactive elements in it, that have no business being in a star I also greatly enjoy that Przybylski's Twitter handle is "@ShuhBillSki" to help people know how to say his name

Quasars are the bright cores of distant galaxies and they are powered by supermassive black holes. The black hole in this record-breaking quasar is growing in mass by the equivalent of one Sun per day, making it the fastest-growing black hole to date
