Something strange is happening on Jupiter’s icy moon Europa — and it has scientists around the world on edge. Recent data has confirmed that Europa is sending out radio signals that are not only consistent but growing stronger over time. These signals, detected by powerful radio telescopes, appear to be coming directly from the moon and are unlike anything we have ever heard before from a celestial body.

🚀 Voyager 1 Sent Back Its “Final Image” — What Did It See?
- The Context
Voyager 1, launched in 1977, is the farthest human-made object from Earth.
It crossed the heliopause in 2012, entering interstellar space — beyond the Sun’s magnetic influence.
Its instruments are mostly still active, but the camera was shut off in 1990 to conserve power, so Voyager cannot take new images today.
- What We Actually Have
The most famous image Voyager 1 sent was the “Pale Blue Dot” (1990): Earth appearing as a tiny speck in a sunbeam, taken from 6 billion kilometers away.
Voyager continues to send back particle, magnetic field, and plasma data, giving scientists insight into interstellar space.
- Why It Feels Like a “Final Image”
Because Voyager 1 no longer has a functioning camera, the Pale Blue Dot image is symbolic — the last photograph of our solar system from its perspective.
All current “images” are visualizations from data, not photographs.
- What Voyager 1 Revealed
The heliopause is turbulent, with unexpected magnetic interactions.
Cosmic rays from outside the solar system are stronger than anticipated.
The probe shows interstellar space is dynamic, not empty.
