SpaceX's Starlink satellites are emanating low-frequency waves from their onboard electronics, messing with astronomical equipment.

A new study published in the journal Astronomy & Astrophysics suggests the satellites are emitting “unintended” radiation from the electronics onboard the satellites.

These low-frequency radio waves, are being picked up by telescopes designed to scan that frequency range. That’s because this range also happens to be instrumental to deep space observations.
