Jupiter's Great Red Spot Getting Taller as it Shrinks

Discover how a team of our scientists has uncovered evidence that Jupiter’s Great Red Spot is growing taller as it gets smaller.

Though once big enough to swallow three Earths with room to spare, Jupiter’s Great Red Spot has been shrinking for a century and a half. Nobody is sure how long the storm will continue to contract or whether it will disappear altogether.

A new study suggests that it hasn’t all been downhill, though. The storm seems to have increased in area at least once along the way, and it’s growing taller as it gets smaller.

Observations of Jupiter date back centuries, but the first confirmed sighting of the Great Red Spot was in 1831. But until then, researchers aren’t certain whether earlier observers who saw a red spot on Jupiter were looking at the same storm.

Amy Simon, an expert in planetary atmospheres at our Goddard Space Flight Center in Greenbelt, Maryland, and her team traced the evolution of the Great Red Spot, analyzing its size, shape, color and drift rate. They also looked at the storm’s internal wind speeds, when that information was available from spacecraft.

This new study confirms that the storm has been decreasing in diameter overall since 1878 and is now big enough to accommodate just over one Earth at this point. Then again, the historical record indicates the area of the spot grew temporarily in the 1920s. Scientists aren’t sure why it grew for a bit.

Because the storm has been contracting, the researchers expected to find the already-powerful internal winds becoming even stronger, like an ice skater who spins faster as she pulls in her arms.

But that’s not what is happening. Instead of spinning faster, the storm appears to be forced to stretch up. It’s almost like clay being shaped on a potter’s wheel. As the wheel spins, an artist can transform a short, round lump into a tall, thin vase by pushing inward with his hands. The smaller he makes the base, the taller the vessel will grow.

The Great Red Spot’s color has been deepening, too, becoming is a more intense orange color since 2014. Researchers aren’t sure why that’s happening, but it’s possible that the chemicals coloring the storm are being carried higher into the atmosphere as the spot stretches up. At higher altitudes, the chemicals would be subjected to more UV radiation and would take on a deeper color.

In some ways, the mystery of the Great Red Spot only seems to deepen as the iconic storm gets smaller. Researchers don’t know whether the spot will shrink a bit more and then stabilize, or break apart completely.

2017 Was One of Our Planet’s Hottest Years on Record

We just finished the second hottest year on Earth since global temperature estimates first became feasible in 1880. Although 2016 still holds the record for the warmest year, 2017 came in a close second, with average temperatures 1.6 degrees Fahrenheit higher than the mean.

2017’s temperature record is especially noteworthy, because we didn’t have an El Niño this year. Often, the two go hand-in-hand.

El Niño is a climate phenomenon that causes warming of the tropical Pacific Ocean waters, which affect wind and weather patterns around the world, usually resulting in warmer temperatures globally. 2017 was the warmest year on record without an El Niño.

We collect the temperature data from 6,300 weather stations and ship- and buoy-based observations around the world, and then analyze it on a monthly and yearly basis. Researchers at the National Oceanic and Atmospheric Administration (NOAA) do a similar analysis; we’ve been working together on temperature analyses for more than 30 years. Their analysis of this year’s temperature data tracks closely with ours.

The 2017 temperature record is an average from around the globe, so different places on Earth experienced different amounts of warming. NOAA found that the United States, for instance, had its third hottest year on record, and many places still experienced cold winter weather.

Other parts of the world experienced abnormally high temperatures throughout the year. Earth’s Arctic regions are warming at roughly twice the rate of the rest of the planet, which brings consequences like melting polar ice and rising sea levels.

Increasing global temperatures are the result of human activity, specifically the release of greenhouse gases like carbon dioxide and methane. The gases trap heat inside the atmosphere, raising temperatures around the globe.

We combine data from our fleet of spacecraft with measurements taken on the ground and in the air to continue to understand how our climate is changing. We share this important data with partners and institutions across the U.S. and around the world to prepare and protect our home planet.

Earth’s long-term warming trend can be seen in this visualization of NASA’s global temperature record, which shows how the planet’s temperatures are changing over time, compared to a baseline average from 1951 to 1980.

Roses are red, that much is true, but violets are purple, not fucking blue.

feels-for-the-fictional

I have been waiting for this post all my life.

marzipanandminutiae

They are indeed purple, But one thing you’ve missed: The concept of “purple” Didn’t always exist.

Some cultures lack names For a color, you see. Hence good old Homer And his “wine-dark sea.”

A usage so quaint, A phrasing so old, For verses of romance Is sheer fucking gold.

So roses are red. Violets once were called blue. I’m hugely pedantic But what else is new?

ineptshieldmaid

My friend you’re not wrong About Homer’s wine-ey sea! Colours are a matter Of cultural contingency;

Words are in flux And meanings they drift But the word purple You’ve given short shrift.

The concept of purple, My friends, is old And refers to a pigment once precious as gold.

By crushing up molluscs From the wine-dark sea You make a dye: Imperial decree

Meant that in Rome, to wear purpura was a privilege reserved

For only the emperor!

The word ‘purple’, for clothes so fancy, Entered English By the ninth century

.

Why then are voilets Not purple in song? The dye from this mollusc, known for so long

Is almost magenta; More red than blue. The concept of purple is old, and yet new.

The dye is red, So this might be true: Roses are purple And violets are blue

.

squeeful

While this song makes me merry, Tyrian purple dyes many a hue From magenta to berry And a true purple too.

But fun as it is to watch this poetic race The answer is staring you right in the face: Roses are red and violets are blue Because nothing fucking rhymes with purple.
