Mysterious Radio Signals Are Coming From A Galaxy Over A Billion Light-Years Away

Far out.

This Hubble Space Telescope view of the core of one of the nearest globular star clusters, called NGC 6397, resembles a treasure chest of glittering jewels. The cluster is located 8,200 light-years away in the constellation Ara. Here, the stars are jam-packed together. The stellar density is about a million times greater than in our Sun's stellar neighborhood. The stars are only a few light-weeks apart, while the nearest star to our Sun is over four light-years away. The stars in NGC 6397 are in constant motion, like a swarm of angry bees. The ancient stars are so crowded together that a few of them inevitably collide with each other once in a while. Near misses are even more common. Even so, collisions only occur every few million years or so. That's thousands of collisions in the 14-billion-year lifetime of the cluster. (Photo by NASA/WireImage)

Americans are terrified of what would happen if aliens invaded while Trump is president.

Some would be fine if they took a few of us with them.

According to scientists, extraterrestrial life is one of the less likely culprits, but the beauty of a repeating frequency is that scientists can use the patterns for clues as to what the source may be.
