Bursts
of solar winds caused a huge sparkling region on Uranus, scientists observed this
by using Hubble space telescope. Electrons that come from various origins such
as solar winds, the planetary ionosphere and moon volcanism, when charged in
the form of streams caused this, researchers from the Paris Observatory used
the NASA/ESA Hubble Space Telescope to observe this on
Uranus.
They
were able to catch it in powerful magnetic fields and, controlled it into the
upper atmosphere, where set off spectacular bursts of light when made
interactions with gas particles, such as oxygen or nitrogen.
Researches
have also been made in 2012 and 2014 on this. A team led by an astronomer from
Paris Observatory took a second look at the auroras using the ultraviolet
capabilities of the Space Telescope Imaging Spectrograph (STIS) installed on
Hubble. Two powerful bursts of solar wind traveling from the sun to Uranus
caused the interplanetary shocks and these shocks are tracked by the Scientists
by using Hubble.
They
found themselves observing the most intense auroras ever seen on the planet. They
collected the first direct evidence that these powerful shimmering regions
rotate with the planet, when they watched the auroras over time.
They
also re-discovered Uranus’ long-lost magnetic poles, which were lost shortly
after their discovery by Voyager 2 in 1986 due to uncertainties in measurements
and the featureless planet surface.
