before that.

The average global temperature on Neptune unexpectedly fluctuated during
a recent 17-year period, according to a new study published by the
American Astronomical Society in The Planetary Science Journal.
Researchers, including scientists from NASA, analyzed ground-based
images of Neptune taken in the mid-infrared range between 2003 and 2020.
The images reveal Neptune’s stratosphere appears to have cooled between
2003 and 2009, followed by a dramatic warming of the south pole between
2018 and 2020. Conversely, upper-tropospheric temperatures didn’t vary
much except for the south pole, which appeared warmest between 2003 and
2006.
Scientists had expected seasons would change slowly on Neptune because
it takes the planet so long to orbit the Sun – 165 years.

The discovery: Saturn's vast ring system is heating the giant planet's
upper atmosphere. The phenomenon has never before been seen in the solar
system. It's an unexpected interaction between Saturn and its rings that
potentially could provide a tool for predicting if planets around other
stars have glorious Saturn-like ring systems, too.
The telltale evidence is an excess of ultraviolet radiation, seen as a
spectral line of hot hydrogen in Saturn's atmosphere. The bump in
radiation means that something is contaminating and heating the upper
atmosphere from the outside.

An unexpected ‘heat wave’ of 700 degrees Celsius, extending 130,000
kilometres (10 Earth diameters) in Jupiter’s atmosphere, has been
discovered. James O’Donoghue, of the Japanese Aerospace Exploration
Agency (JAXA), has presented the results this week at the Europlanet
Science Congress (EPSC) 2022 in Granada.
Jupiter’s atmosphere, famous for its characteristic multicoloured
vortices, is also unexpectedly hot: in fact, it is hundreds of degrees
hotter than models predict. Due to its orbital distance millions of
kilometres from the Sun, the giant planet receives under 4% of the
amount of sunlight compared to Earth, and its upper atmosphere should
theoretically be a frigid -70 degrees Celsius. Instead, its cloud tops
are measured everywhere at over 400 degrees Celsius.
Looking more deeply through their data, Dr O’Donoghue and his team
discovered the spectacular ‘heat wave’ just below the northern aurora,
and found that it was travelling towards the equator at a speed of
thousands of kilometres per hour.
The heat wave was probably triggered by a pulse of enhanced solar wind
plasma impacting Jupiter’s magnetic field, which boosted auroral heating
and forced hot gases to expand and spill out towards the equator.

According to National Geographic: "Habibullo Abdussamatov, head of the
St. Petersburg's Pulkovo Astronomical Observatory in Russia, says the
Mars data is evidence that the current global warming on Earth is being
caused by changes in the sun.
‘The long-term increase in solar irradiance is heating both Earth and
Mars,’ Abdussamatov said."
This scientific research regarding Mars and the Sun, follows another new
study about the impact of cosmic rays on the Earth’s climate. A release
from the Danish National Space Center details the latest research from
scientists from Denmark, Canada and Israel.
"Nir Shaviv of the Hebrew University in Jerusalem, together with Ján
Veizer of the Ruhr University and the University of Ottawa, link
[Earth’s temperature] changes to the journey of the Sun and the Earth
through the Milky Way Galaxy," the release stated.
The leader of Sun-climate research at the Danish National Space Center,
Henrik Svensmark said, "The past 10 years have seen the reconnaissance
of a new area of research by a small number of investigators.'"

NASA's Mars Global Surveyor and Mars Odyssey missions have provided
evidence of a relatively recent ice age on Mars. In contrast to Earth's
ice ages, a Martian ice age waxes when the poles warm, and water vapor
is transported toward lower latitudes. Martian ice ages wane when the
poles cool and lock water into polar icecaps.
The "pacemakers" of ice ages on Mars appear to be much more extreme than
the comparable drivers of climate change on Earth. Variations in the
planet's orbit and tilt produce remarkable changes in the distribution
of water ice from Polar Regions down to latitudes equivalent to Houston
or Egypt. Researchers, using NASA spacecraft data and analogies to
Earth's Antarctic Dry Valleys, report their findings in Thursday's
edition of the journal Nature.
"Of all the solar system planets, Mars has the climate most like that of
Earth. Both are sensitive to small changes in orbital parameters," said
planetary scientist Dr. James Head of Brown University, Providence,
R.I., lead author of the study. "Now we're seeing that Mars, like Earth,
is in a period between ice ages," he said.

Mars will continue to warm as the Sun heats up throughout its lifetime.
•
Mars will reach the melting temperature of water ice, and both CO2 and
H2O will be mobilized at the surface.
•
Mars could end up with a climate conducive to supporting life.
•
Results show the importance of processes intrinsic to a planet in
determining the climate and habitability of an exoplanet.
As the solar luminosity continues to increase over the next 6 billion
years, the Martian surface will heat up to above the melting temperature
of water ice.
