Watch the king of the planets turn on its throne

NASA’s Juno spacecraft finds lightning bolts in Jupiter’s atmosphere are similar to discharges on Earth, but they only occur at high latitudes thanks to the giant planet’s distance from the sun

From its perch in orbit around Jupiter, NASA’s Juno spacecraft routinely provides stunning views of the giant planet’s turbulent atmosphere and the Great Red Spot. But a jaw-dropping close-range look at Io’s shadow during an eclipse is yet another show stopper.

Contradicting the long-standing idea that large Jupiter-mass planets take a minimum of 10 million years to form, astronomers have just announced the discovery of a giant planet in close orbit around a 2 million-year-old star that still retains a disc of circumstellar gas and dust. CI Tau b is at least eight times larger than Jupiter and 450 light-years from Earth.
