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.
