Meteor Magnets in outer space—study finds elusive Giant Planets

The ‘wobble,’ or radial velocity technique for finding planets relies on the movement of the stars created as they’re circled by their planets. The blue wave represents movement toward Earth, while the red wavelength occurs as the star heads away. Credit: (NASA/JPL-Caltech)

Astronomers believe planets like Jupiter shield us from space objects that would otherwise slam into Earth. Now they’re closer to learning whether giant planets act as guardians of solar systems elsewhere in the galaxy.

A UCR-led team has discovered two Jupiter-sized planets about 150 light years away from Earth that could reveal whether life is likely on the smaller planets in other solar systems.

“We believe planets like Jupiter have profoundly impacted the progression of life on Earth...

Jupiter’s Unknown Journey Revealed

Jupiter was formed four times further from the sun than its current position would indicate, according to a new simulation.

The giant planet Jupiter was formed four times further from the sun than its current orbit, and migrated inwards in the solar system over a period of 700,000 years. Researchers found proof of this incredible journey thanks to a group of asteroids close to Jupiter.

It is known that gas giants around other stars are often located very near their sun. According to accepted theory, these gas planets were formed far away and subsequently migrated to an orbit closer to the star.

Now researchers from Lund University and other institutions have used advanced computer simulations to learn more about Jupiter’s journey through ou...

New Surprises from Jupiter and Saturn

Latest data on Jupiter and Saturn from Juno and Cassini missions challenge current theories of planetary formation. The latest data sent back by the Juno and Cassini spacecraft from giant gas planets Jupiter and Saturn have challenged a lot of current theories about how planets in our solar system form and behave.

The detailed magnetic and gravity data have been “invaluable but also confounding,” said David Stevenson from Caltech, who will present an update of both missions this week at the 2019 American Physical Society March Meeting in Boston.

“Although there are puzzles yet to be explained, this is already clarifying some of our ideas about how planets form, how they make magnetic fields and how the winds blow,” Stevenson said.

Jupiter’s Atmospheric Beauty is more than Skin Deep

NASA’s Juno discovers a brand new Jupiter. In the year and a half NASA’s Juno spacecraft has been orbiting Jupiter, the science team led by Southwest Research Institute’s Dr. Scott Bolton has discovered that the orange and white bands that characterize Jupiter’s outer atmosphere extend thousands of miles into the gas giant’s atmosphere. The findings are part of a four-article collection about Juno science results in the March 8th edition of the journal Nature.

“With Juno only about a thir...
