Space is filled with strange signals, but some are so mysterious that even scientists can’t explain them. Here are the top 5 weirdest space signals ever recorded:
1️⃣ The SHGb02+14a Signal (2003)
- A radio signal detected from deep space at 1420 MHz—a frequency that hydrogen atoms naturally emit.
2️⃣ The “Fast Radio Burst” (FRBs) Mystery
- Short, powerful bursts of radio waves that last just milliseconds, coming from billions of light-years away.
3️⃣ The Lorimer Burst (2007)
- The first confirmed Fast Radio Burst—it had the energy of 500 million suns, but lasted just a few milliseconds.
4️⃣ The Green Bank Signal (2019)
- A repeating radio transmission coming from a nearby exoplanet every 16 days.
5️⃣ The Wow! Signal (1977)
- The most famous unexplained signal—some scientists believe it could have been sent by extraterrestrials.
Could these signals be natural cosmic phenomena—or alien communication attempts?
