NASA’s Juno Mission Reveals Jupiter’s Complex Colors



NASA’s Juno spacecraft observed the complex colors and structure of Jupiter’s clouds as it completed its 43rd close flyby of the giant planet on July 5, 2022.

Citizen scientist Björn Jónsson created these two images using raw data from the JunoCam instrument aboard the spacecraft. At the time the raw image was taken, Juno was about 3,300 miles (5,300 kilometers) above Jupiter’s cloud tops, at a latitude of about 50 degrees. North is up. At that moment, the spacecraft was traveling at about 130,000 mph (209,000 kilometers per hour) relative to the planet.

The first image (left) was processed to portray the approximate colors that the human eye would see from Juno’s vantage point. The second image (right) comes from the same raw data, but in this case Jónsson digitally processed it to increase both the color saturation and contrast to sharpen small-scale features and to reduce compression artifacts and noise that typically appear in raw images. This clearly reveals some of the most intriguing aspects of Jupiter’s atmosphere, including color variation that results from differing chemical composition, the three-dimensional nature of Jupiter’s swirling vortices, and the small, bright “pop-up” clouds that form in the higher parts of the atmosphere.

That Uplifting Tweet You Just Shared? A Russian Troll Sent It

Image
Here’s what Russia’s 2020 disinformation operations look like, according to two experts on social media and propaganda. By   DARREN LINVILL   &   PATRICK WARREN Internet trolls don’t troll. Not the professionals at least. Professional trolls don’t go on social media to antagonize liberals or belittle conservatives. They are not narrow minded, drunk or angry. They don’t lack basic English language skills. They certainly aren’t  “somebody sitting on their bed that weighs 400 pounds,”  as the president once put it. Your stereotypical trolls do exist on social media, but the amateurs aren’t a threat to Western democracy. Professional trolls, on the other hand, are the tip of the spear in the new digital, ideological battleground. To combat the threat they pose, we must first understand them — and take them seriously.

The Nightmare Scenario That Keeps Election Lawyers Up At Night -- And Could Hand Trump A Second Term

The Nightmare Scenario That Keeps Election Lawyers Up At Night -- And Could Hand Trump A Second Term   (Photo: Photos: Getty Images) Americans will almost certainly go to bed on Nov. 3 without knowing who won the presidential election. Since millions of people will vote by mail, constraints on time and resources will slow ballot counting into potentially a weeks-long process. Voting patterns suggest it’s likely that President  Donald Trump  could end Election Day in the lead in certain key states, only to be overtaken by Democratic opponent  Joe Biden  when more votes are tallied.  This could create a nightmare scenario during the three months stretching from Election Day to the Jan. 20 inauguration: a battle on the state and congressional level over who is the legitimate winner. This could include Congress reconvening on Jan. 6, presided over by Vice President  Mike Pence , with no consensus over its potential role in choosing the next president. This is arguably the most likely of th

Philosophical Question #14 – Lifestyle Choices

Image
Here is an interesting question in my list of philosophical questions: 1.) Should governments have penalties for those who live unhealthy lifestyles? A list of unhealthy lifestyles would include things like smoking, drinking, illegal drugs, prostitution, and other “vice” type activities. I guess the “government penalties” would be referring to monetary punishments, withholding medical treatments (insurance companies would love that), possibly imposing/regulating very high (exorbitant) prices on things considered unhealthy in order to cut down on their use, and other possibilities. 2.) Or, would you say that living an unhealthy lifestyle, likely resulting in a LOT of eventual personal pain and suffering, should be punishment enough for unhealthy lifestyles? When people make bad choices in life, often in their youth where ignorance and immediate gratification takes them over,  3.) Should a society be obligated to help "fix" them, by way of tax money?   Is that part of
