Oh Boy, Mercury Is Gonna Transit the Sun


#Mercury #NASA #Sun #Astronomy 

Mercury will transit the Sun for the first time since 2016 this coming Monday. It won’t do so again until 2032.

The smallest planet’s eccentric orbit means it doesn’t often pass in front of the Sun from Earth’s vantage point. This year, part of the 5.5-hour transit will be visible to much of North America starting at 7:36 a.m. ET. The eastern half of North America and all of South America will see the whole show, which will last until 1:04 p.m. ET. Africa, Europe, and western Asia will be able to see it at Monday’s sunset.

How can you see it? Well, I’d advise against staring directly into the Sun and even more strongly against staring into the Sun through binoculars or a telescope. Instead, it’s best to use a telescope with a solar filter, through which the transit will look like a small black speck passing in front of the Sun, which will appear 194 times larger than the speck. If you don’t have those tools, check if a local astronomy club will be hosting a public viewing. The Virtual Telescope Project will have a viewing on its website.

Transits occur when planets come between us and the Sun, meaning that only two planets can transit: Venus and Mercury. Witnessing a transit is all a matter of timing. Transits of Venus occur in pairs separated by 121.5 or 105.5 years, with eight years separating each transit; the next transit of Venus will occur in the year 2117. Transits of Mercury are far more frequent, since the planet travels on a smaller orbit around the Sun.

Mercury transits have long been useful tools for scientists. Back in the 17th century, astronomers observed transits of Mercury to try to determine the distance between the Earth and Sun using parallax—observing the transit from two different places on Earth, as National Radio Astronomy Observatory astronomer Brian Koberlein wrote for Forbes. One team used the transits to indirectly calculate the effect of tidal forces of the Moon on Earth. More recently, one team of scientists used a transit to see whether it would produce a discernible decrease in the amount of sunlight (it did not). That knowledge is valuable to astronomers hoping to use the transit method to spot exoplanets around distant stars.

Hopefully, you’ll have an opportunity to watch the transit on Monday. But remember, don’t look directly at Mr. Sun

Coors Light will cover dog adoption fees across the country until Feb. 21

#CoorsLight #DogAdoptions #COORS4k9   A day after former Florida State Seminoles and Kansas City Chiefs defensive lineman Derrick Nnadi paid for dog adoptions at a Kansas City shelter, Coors Light said hold my beer…literally.   Coors Light announced it will reimburse up to $100 in fees for 1,000 dog adoptions across the country for pups taken to their forever homes. The offer is good through Feb. 21 for adopters who are 21 or older.     “Cuffing Season is a major cultural trend and poses tension for our younger drinkers, as they navigate the stress of finding someone to spend the cold months with,” Chelsea Parker, marketing manager at Molson Coors, said in a statement. “With almost half of millennials planning to stay in on Valentine’s Day, we wanted to help empower people to savor the day with Coors Light and a dog by their side.”  Eligible participants can text “COORS4k9” and a picture of their adoption receipt to 28130. After review, th...

A Brief History of Skittles - Taste the rainbow

#Candy #Skittles #TastetheRainbow The candy that we are so familiar with today first came into existence in 1974. Skittles spent the first five years of their lives solely in Britain since it wasn’t until 1979 that North America got a chance to taste  the  rainbow. There is much speculation surrounding the creator of Skittles, as nobody really knows exactly who first made them. One story suggests that a British man named Mr. Skittles looked at a rainbow one day and wondered how it would taste. Other sources state that the Wrigley Company, founded in 1891, created candy and other confectionery, including Extra chewing gum. However, although Wrigley produces Skittles today, it is widely accepted that an unknown British company was the original manufacturer. After three years of being imported to North America from the UK, Skittles started being manufactured in the US and Britain. There were very few flavors compared to the varieties available today. Consumers enjoyed gra...

Coping With Moods: The Challenge of the Turbulent Mind

#Mood #Impulses #selfregulate #selfsoothe  #Triple5LightTherapy #BlackMaleTherapist #Psychotherapy The power of moods and impulses can be overwhelming, but we can learn to self-regulate and self-soothe through awareness practices like meditation and mindfulness. By developing a healthy dialogue with our emotional nature, we can access deeper parts of ourselves and become more resilient in the face of stress and pressure. Rather than being swept away by our ever-shifting moods, we can learn to pause and reflect before acting. by Gillian McCann, Ph.D., and Gitte Bechsgaard, RP
