Story summary

Canadian amateur satellite tracker Scott Tilley identified that SpaceX's Starshield network is transmitting in the 2025–2110 MHz uplink range.
The transmissions could violate International Telecommunication Union (ITU) standards and risk interfering with radio astronomy.
Experts warn the emissions could mask faint signals crucial for understanding the interstellar object 3I/ATLAS as astronomers prepare to observe it.
SpaceX and the U.S. government have not commented on the situation.
