TUMBLING IN CHAOS

“Data from the Hubble telescope has shown that two of Pluto’s moons “wobble
unpredictably,” according to NASA.

The data has revealed “a cosmic dance with a chaotic rhythm,” said
John Grunsfeld, associate administrator of NASA’s Science Mission Directorate
in Washington.

The New Horizons spacecraft is rapidly approaching Pluto, and the moons will be
studied in closer detail when it flies by in June.

According to the data, the moons Nix and Hydra are wobbling because of shifting
gravitational fields, caused by the double planet system of Pluto and Charon
whirling about each other. It is also thought that its other moons, Kerberos and
Styx, are behaving similarly.

The Hubble telescope has helped us discover all kinds of important things about
the universe, like how there’s a smiley face made up of faraway galaxies.“
