FOR KIDS: Galaxies on the go

Millions of stars are mysteriously racing toward one point in the sky

Scientists have a mystery of cosmic proportions on their hands. Recently astronomers noticed something strange. It seems that millions of stars are racing at high speeds toward a single spot in the sky.

Huge collections of stars, gas and dust are called galaxies. Some galaxies congregate into groups of hundreds or thousands, called galaxy clusters. These clusters can be observed by the X-rays they give off.

Scientists are excited about the racing clusters because the cause of their movement can't be explained by any known means.
