NASA Releases Incredible Photo of ISS Passing Across the Sun

ISS Flying in Front of the Sun

A photo of the sun with a glimpse of the International Space Station as it orbits the Earth was recently featured by NASA and it would be stunning enough on its own; however, the image is made all the more special because it features the Sun at a time when there are no sunspots. Thanks to Rainee Colacurcio, who captured the photo, the world is able to enjoy this unique moment.

Colacurcio has also posted several other photographs of ISS transiting the Sun, demonstrating her skill level in taking such a technically difficult photograph. “Transiting the Sun is not very unusual for the ISS, which orbits the Earth about every 90 minutes, but getting one’s timing and equipment just right for a great image is rare,” wrote NASA, who featured the photograph as its Astronomy Picture of the Day.

In order to get the final appearance, two photographs were composited together. The first featured the space station as it transited the Sun, while the other was taken in order to capture the details of the Sun’s surface. It’s in these details that we can see the lack of sunspots. This isn’t entirely unusual because we’re currently in a period of low solar activity known as the Solar Minima.

This cycle can last for at least 11 years and, during this time, the Sun can go days without solar flare or sunspots. Still, NASA notes that sunspot activity is currently quite low, even for a Solar Minima. What is a sunspot exactly? These temporary spots appear on the Sun’s outer shell thanks to reduced temperatures caused by magnetic fields. Looking like black patches on the Sun, they can be as large as planets and last for months. Though scientists don’t know exactly why we’re experiencing a reduced number of sunspots currently, it certainly makes for a beautiful photograph.

This incredible photo of the ISS transiting the Sun is made all the better by the lack of sunspots on the enormous star.

How to train your brain to have lucid dreams – Neuroscience News

Summary: A sleep researcher shares the secrets for training your brain to experience lucid dreams. Source: The Conversation Dreams can often be confusing and blurry experiences . Reduced critical thinking, little to no access to our true memories and heightened impulsivity and emotions during normal dream states often make for head-scratching moments when our eyes first open in the morning. But dreams don’t always play out this way. More than half of us have at least once in their lifetime experienced awareness of dreaming in the moment and, in some cases, the ability to direct a dream like a sleepy Steven Spielberg. Nearly a quarter of us report lucid dreaming once a month or more. Two key changes in the brain appear responsible for these states. The frontotemporal cortex, which controls our higher cognitive abilities and is inhibited during normal dreams, shows higher activation during lucid dreams. Researchers also observe an increase in gamma waves , synchronised firing by

A veteran in hospice care is reunited with his dog one last time | MNN – Mother Nature Network

After being admitted into hospice care, veteran John Vincent had just one special request: He wanted to spend a little time with his beloved dog. Vincent, a 69-year-old Marine who fought in Vietnam, was placed into the Hospice Center at the Raymond G. Murphy Veterans Affairs Medical Center in New Mexico. Because he had no family in the area to care for his pet, he had to give up his 6-year-old Yorkshire terrier mix named Patch to the Albuquerque Animal Welfare, the organization posted on Facebook . Knowing he likely didn’t have much time left, Vincent told Amy Neal, his palliative care social worker, that he wanted to say goodbye to Patch and see him one last time. Neal reached out to the city’s animal welfare department. “It was an immediate ‘yes’ from us,” Adam Ricci, Albuquerque Animal Welfare chief of field operations, told CNN . “So, we worked with the VA to get things organized.” Patch spent the day on Vincent’s bed.

Experts reveal health benefits of a banana based on its colour – and what brown spots REALLY mean | Daily Mail Online

As one of the cheapest and most satiating fruits, bananas are up there with the most popular snacks you can buy.  And while their health benefits are widely known, few are aware of how the ripeness of a banana impacts on its nutritional make-up. So to help make it clear, Australian sports dietitian Ryan Pinto recently shared a graphic about the various benefits – and why eating an over-ripe banana may not be a great idea.  ‘The best way to understand how the health of a banana can change is by investigating what really happens to them internally over time,’ he wrote on his page, High Performance Nutrition AU .  Australian sports dietitian Ryan Pinto recently shared a graphic about the various benefits of bananas at different stages – and why eating an over-ripe banana may not be a great idea Green bananas  According to Ryan, green bananas are ‘youthful, low FODMAP and full of starch’. ‘Referred to as “resistant” starch, this nutrient makes your digestive system work a little ha
