A solar storm and the Earth's magnetic field as rendered by NASA.

Space Exploration Technologies Corporation's (SpaceX) Starlink satellite internet constellation failed to withstand the impact of a recent disturbance in the Earth's magnetic sphere (magnetosphere) caused by the Sun releasing a storm of charged particles. Starlink launched its latest batch of satellites last week, and the spacecraft was put into an emergency mode once the geomagnetic storm hit the next day on Friday. Now, the company has confirmed that up to 40 of the launched spacecraft have reentered the Earth's atmosphere, marring its rapid launch cadence that kicked off the year with two Starlink launches for a total of 98 satellites.
