Gas-giant planets orbiting close to other stars have powerful magnetic fields, many times stronger than our own Jupiter, according to a new study by a team of astrophysicists. It is the first time the strength of these fields has been calculated from observations.
The team, led by Wilson Cauley of the University of Colorado, also includes associate professor Evgenya Shkolnik of Arizona State University's School of Earth and Space Exploration. The other researchers are Joe Llama of Northern Arizona University and Antonino Lanza of the Astrophysical Observatory of Catania in Italy. Their report was published July 22 in Nature Astronomy.
"Our study is the first to use observed signals to derive exoplanet magnetic field strengths," says Shkolnik. "These signals appear to come from interactions between the magnetic fields of the star and the tightly orbiting planet."
Surprisingly Powerful
The field strengths, the team says, are larger than one would expect considering only the rotation and age of the planet. The standard dynamo theory of planetary magnetic fields predicts field strengths for the sampled planets that are much smaller than what the team found.
Instead, the observations support the idea that planetary magnetic fields depend on the amount of heat moving through the planet's interior. Because they are absorbing a lot of extra energy from their host stars, hot Jupiters should have larger magnetic fields than planets of similar mass and rotation rate.
"We are pleased to see how well the magnitude of the field values corresponded to those predicted by the internal heat flux theory," says Shkolnik. "This may also help us work toward a clearer understanding of magnetic fields around temperate rocky planets."
Gold Nanoparticles in Contact Lenses CouldProtect Your Eyes
Researchers have made a new incognito technology in the form of a “golden eye” that seems like something James Bond would use. The researchers developed contact lenses that use tiny amounts of gold to help protect eyes from damaging light. They hope future versions will deliver medicine or detect diseases. These new contact lenses absorb light and dissipate the energy using tiny, gold-based nanocapsules. In a paper published this month in the journal Applied Materials Today, researchers described the new material and how it absorbs light. They argue that their results demonstrate that it is possible to embed gold nanoparticles within soft contacts while maintaining visibility and that the process might protect wearers' eyes from bright lights.

Lesser known facts
aboutGOOGLE
1. The name ‘Google’
is actually derived
from the
mathematical term
‘googol’ which is
basically 1 with a
100 zeroes following
it.
2.Co-founders Larry
page and Sergey
Brin originally
named Google
‘Backrub’.
3. Google uses a web
tool called foo.bar
to recruit new
employees based on
what they search for
online.
4. Google owns
comman
misspellings of its
own name as well,
such as-
www.gooogle.com ,
www.gogle.com ,
www.googlr.com
5. Like prisnors,
every Google
employee has a
number.
