What happens every 11 years?

The solar cycle is the cycle that the Sun's magnetic field goes through approximately every 11 years. Our Sun is a huge ball of electrically-charged hot gas. This charged gas moves, generating a powerful magnetic field. The Sun's magnetic field goes through a cycle, called the solar cycle.

What is Sun's 11th cycle?

The solar cycle is an approximately 11-year cycle experienced by the Sun. During the solar cycle, the Sun's stormy behavior builds to a maximum, and its magnetic field reverses. Then, the Sun settles back down to a minimum before another cycle begins.

Why is the solar cycle 11 years?

The 11-year sunspot cycle is actually half of a longer, 22-year cycle of solar activity. Each time the sunspot count rises and falls, the magnetic field of the Sun associated with sunspots reverses polarity; the orientation of magnetic fields in the Sun's northern and southern hemispheres switch.

What happens if you live in space for a year?

There's a cornucopia of research that life in space changes your body. Astronauts in microgravity face bone loss and muscle atrophy, depressed immune systems, and sleep problems. Some astronauts have vision changes.Apr 12, 2019

Does the Sun change polarity every 11 years?

The sun's magnetic field changes polarity approximately every 11 years. It happens at the peak of each solar cycle as the sun's inner magnetic dynamo re-organizes itself. The coming reversal will mark the midpoint of Solar Cycle 24. Half of "solar max" will be behind us, with half yet to come.Dec 6, 2013

How many sunspots will there be in 2022?

Do sunspots make it hotter on Earth?

Sunspots have been observed continuously since 1609, although their cyclical variation was not noticed until much later. At the peak of the cycle, about 0.1% more Solar energy reaches the Earth, which can increase global average temperatures by 0.05-0.1℃. This is small, but it can be detected in the climate record.Sep 1, 2020

In what year did the last solar maximum occur?

April 2014Solar maximum occurred in April 2014 with sunspots peaking at 114 for the solar cycle, well below average, which is 179. Solar Cycle 24's progression was unusual. The Sun's Northern Hemisphere led the sunspot cycle, peaking over two years ahead of the Southern Hemisphere sunspot peak.

What caused sunspots?

Sunspots are caused by disturbances in the Sun's magnetic field welling up to the photosphere, the Sun's visible "surface". The powerful magnetic fields in the vicinity of sunspots produce active regions on the Sun, which in turn frequently spawn disturbances such as solar flares and coronal mass ejections (CMEs).

Who is Ira Flatow?

I’m Ira Flatow. A bit later in the hour, we’ll talk about the cherry blossom hunter, English ornithologist, and naturalist Collingwood Ingram, who gave up studying birds to devote his life to cataloging and preserving rare flowering cherry varieties. Subject of the new book, The Sakura Obsession.

Who is Christie Taylor?

Christie Taylor is a producer for Science Friday. Her day involves diligent research, too many phone calls for an introvert, and asking scientists if they have any audio of that narwhal heartbeat.

How fast does the International Space Station travel?

Daily life aboard the International Space Station moves fast. Really fast. Traveling at approximately 17,000 miles per hour, 300 miles above the Earth , astronauts watch 16 sunrises and sunsets every “day” while floating around in a box with a handful of people they depend on for survival.

What causes telomeres to shorten?

The rate at which telomeres shorten over time is influenced by many factors, including oxidative stress and inflammation, nutrition, physical activity, psychological stresses and environmental exposures like air pollution, UV rays and ionizing radiation.

What are the twins studies?

Studies included molecular, physiological and behavioral measures, and for the first time ever in astronauts, “omics”-based studies. Some teams evaluated the impact of space on the genome – the entire complement of DNA in a cell (genomics). Other teams examined which genes were turned on and producing a molecule called mRNA (transcriptomics). Some studies focused on how chemical modifications – which do not alter the DNA code – affected the regulation of the genes (epigenomics). Some researchers explored the proteins produced in the cells (proteomics), whereas others scrutinized the products of metabolism (metabolomics).

Who is Scott Kelly's brother?

At a press conference not long thereafter, it was Scott who hinted that that this mission might provide the chance to compare the impact of space living on his body with his Earth-dwelling identical twin brother, Mark Kelly, who had also been an astronaut and former Navy test pilot.

Who are the Kelly twins?

The Kelly twins are without a doubt one of the most profiled pairs – on or off our planet. They are also one of the most interviewed. One question often asked is whether Scott will return from space younger than Mark – a situation reminiscent of “Interstellar” or Einstein’s so-called “ Twin Paradox .”.

How long has Scott Kelly been in space?

After spending 340 days in space, U.S. astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko are scheduled to touch down on our little blue marble around 11:30 p.m. ET today. Though not the longest stint in space, it is the longest anyone has spent on board the International Space Station ...

What are the things that scientists discovered in space?

One of the first things that scientists discovered in our ventures into space is that the low-gravity lifestyle doesn’t lend itself to strong bones and muscles, including the heart. While Earth-bound, these body parts actually work a fair amount just to keep us standing still. Without the downward force of gravity, the body works considerably less, causing muscle deterioration and loss of bone density.

How does the inner ear work?

Your inner ear works roughly like an accelerometer in a smartphone—it tells your body when you are moving or stopped, and when you are standing on your head or lying on your side. But in space, that little mechanism goes awry, which often gives astronauts motion sickness for a day or so after entering microgravity.

Where were the art stolen during the Nazi occupation?

During the Nazi occupation of France, many valuable works of art were stolen from the Jeu de Paume museum and relocated to Germany. One brave French woman kept detailed notes of the thefts

Who was the first person to orbit Earth?

Then in 1962, astronaut John Glenn became the first American to orbit Earth, along with a tube of applesauce. “They picked a nice soft, slippery food and put it in a toothpaste tube and had him take just little bits at a time to see if he could swallow and if the food would move down to his stomach,” says Neal.

Does the ISS have a magnetic shield?

Earth's magnetic field provides a form of natural shielding that protects life on the surface from a good amount of high-energy radiation, which could otherwise damage DNA. Outside this safe zone, artificial shielding on the ISS can partially protect astronauts from radiation exposure, but it isn’t effective for all radiation types, leaving astronauts more susceptible to cancer and other long-term health risks.

Why is the Sun so active?

The Sun is typically very active when sunspot counts are high. Sunspots are indicators of disturbances in the Sun's magnetic field, which can generate energetic solar events like solar flares and coronal mass ejections.

How long is the Sunspot cycle?

The duration of the sunspot cycle is, on average, around eleven years. However, the length of the cycle does vary. Between 1700 and the present, the sunspot cycle (from one solar min to the next solar min) has varied in length from as short as nine years to as long as fourteen years.

Where are sunspots located?

At solar min, sunspots tend to form around latitudes of 30° to 45° North and South of the Sun's equator. As the solar cycle progresses through solar max, sunspots tend to appear closer to the equator, around a latitude of 15°.

Who is Scott Kelly?

Few people know this better than Scott Kelly, the NASA astronaut who spent nearly a year on the International Space Station from 2015 to 2016. Like other astronauts, Kelly served as a test subject in the study of space travel’s effects on the human body. Unlike other astronauts, Kelly has an identical twin, Mark, an astronaut himself.

Who is running for Senate in Arizona?

Another important mission is coming up: the 2020 election. Mark Kelly , also retired, is running for a Senate seat in Arizona. Maybe some researchers would like to see how astronauts do in a different kind of stressful situation.

Is space travel stressful?

Some of the effects were no more dramatic than stress-related changes studied on Earth—and space travel is certainly stressful. The others, such as the eyeball squishing, can clearly be attributed to Scott’s unique experience in space. But that’s where the explanations end.

Does Kelly have a twin?

Unlike other astronauts, Kelly has an identical twin, Mark, an astronaut himself. This gave researchers an uncommon opportunity to monitor the two brothers as they lived in two very different environments—one on Earth and the other 250 miles above it. According to their results, published Thursday in Science, Scott experienced a number ...

What is the afterlife?

Many people believe in an afterlife, a concept that not only denies the finality of death but literally describes it as a different form of life. Perhaps the most glaring example is the open-casket funeral, when humans go through the effort of dressing up a dead person in nice attire and laying them in a giant jewelry box with plush lining, ...

What happens to the brain after death?

After spending its whole life trying to keep the rest of you alive, in death your brain does the same thing in much more dramatic fashion. As detailed in What We Leave Behind, after four minutes of oxygen deprivation, your brain cells will break themselves down in a process called autolysis. Per Scientific American, that breakdown results from one of the very processes that once kept your cells alive: breathing. Breathing produces carbon dioxide, which is acidic. During autolysis, that carbon dioxide ruptures your cells, which in turn release nutrients that other cells can use.

How much water is in the brain?

Meanwhile, things get gooey in the coffin. As Business Insider describes, the fluid in your brain cells, which are about 70 percent water, leak onto the floor of your final resting box.

Why do clothes decompose?

After a little more than a year, your clothes will decompose because of exposure to the various chemicals your corpse produced. And like that, you've gone from being a sleeping beauty to naked mush.

What happens when you breathe in cold water?

Breathing produces carbon dioxide, which is acidic. During autolysis, that carbon dioxide ruptures your cells, which in turn release nutrients that other cells can use. Part of the timing is temperature-dependent. Cold temperatures delay the onset of autolysis, which is the reason that people who have drowned in freezing water can sometimes be ...

Can you rest in one piece after death?

No matter how peaceful your death is, you'll never rest in one piece, thanks to the magic of decomposition. But under certain circumstances — particularly, if your coffin is kept above ground in a mausoleum — the rest of your pieces could be flung everywhere as your coffin explodes in a blaze of, well, not glory, but gory.

Mapping The Solar System’S Edge, One Particle at A Time

Shaping Up The Heliosphere

  • From 2009 to 2014, the wind blew fairly low and steady, a gentle breeze. The heliosphere contracted. Then came a surprise swell in the solar wind, as if the sun heaved a great sigh. In late 2014, NASA spacecraft orbiting Earth detected the solar wind pressure increase by about 50 percent — and it has remained high since then. Two years later, the b...
