Researchers have made a new discovery about a huge and long-lasting storm in the atmosphere of the planet Jupiter.
A study published recently in Science says that Jupiter's Great Red Spot, a storm wide enough to cover the Earth, is also extremely deep.
The U.S. space agency NASA's spacecraft, Juno, is using special tools to make images of the planet.
Scott Bolton of the Southwest Research Institute in Texas was the lead scientist in the study.
He said microwave radiation and gravity-mapping tools from Juno show the storm "fades out" slowly and "keeps going down."
He explained that the storm does not have a clear ending point below the clouds.
The storm probably has a depth between 350 and 500 kilometers.
It is 16,000 kilometers wide.
The planet is known for powerful storms in its atmosphere.
Thousands of storms swirl around Jupiter at any time, scientists said.
The storms cause the colorful cloud patterns shown by photography and mapping tools.
Some of the tools produce images in three dimensions.
Bolton said the next project for Juno is to map the storms in the extreme north and south of the planet.
They could be even deeper than the Great Red Spot.
Bolton said he did not want to guess that the Great Red Spot was the deepest of the planet's storms.
He said, however, since the spot is the widest, it might also be the deepest.
The Juno spacecraft started orbiting Jupiter in 2016.
NASA recently announced the project will be extended to 2025.
