Something's wrong with the sun again

“The very existence of HFR modes and their origin is a true mystery
and may allude to exciting physics at play. It has the potential to
shed insight on the otherwise unobservable interior of the Sun,”
said Shravan Hanasoge, the paper’s co-author and astrophysicist
at NYU Abu Dhabi’s Center for Space Science. The study
(https://bit.ly/3LsG43W) was directed by researchers from NYU
Abu Dhabi’s Center for Space Science in cooperation with the Tata
Institute of Fundamental Research and NYU. Scientists originally
thought that acoustic solar waves form near the Sun’s surface,
thanks to the Coriolis effect wherein points on a rotating sphere’s
equator seem to move quicker than points on its poles. The Coriolis
effect is an apparent effect (https://bit.ly/3Lx561M) created by
a rotating frame of reference. It happens when an object moving
along a straight way is seen from a non-fixed frame of reference.
Addressing the shortcomings in their knowledge might help the
researchers gain a better understanding of the Sun’s interior in
addition to getting a better sense of how the Sun affects Earth and
other planets in the solar system. It could also provide insight into
the same kind of high-frequency wave known as the Rossby
waves, which had been seen crossing Earth’s oceans four times
faster than current models can explain. Astronomers examine
acoustic waves (https://yhoo.it/3uEUNSC) like these for the reason
that we are still a long way from building technology capable of
peeking deep into the Sun’s interior. NASA, ESA launch solar
probes In 2018, the National Aeronautics and Space Administration
(NASA) launched the Parker Solar Probe, which was named after
the late solar physicist Eugene Parker from Florida’s space coast.
During the course of its seven-year mission, the Parker Solar Probe
will move closer to the Sun than any other spacecraft in history.
It has already broken speed records in just four years, traveling at
a maximum speed of 430,000 mph. It has also done a series of
astonishing discoveries about solar winds, high-energy particles
and much more. In February 2020, the European Space Agency
(ESA) launched the Solar Orbiter probe, which the agency created
to study space weather; the heliosphere or the protective plasma
bubble that encloses our solar system; and the Sun’s poles, a
mysterious area that has never been fully studied. Exactly six
months after it was launched, the Solar Orbiter was able to take
a closer photo of the Sun. The particular image showed the presence
of small solar flares named campfires, which could help explain
why the Sun’s corona – the outermost layer of the Sun’s atmosphere
– is hotter than its surface. The discoveries these probes make
could aid researchers in better foreseeing catastrophic space
weather and comprehending how the Sun’s cycles affect physical
procedures here on Earth.
