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

The crazy story of how ‘Stockholm syndrome’ got its name

#Movies #Hostage #PattyHearst #Psychology #StockholmSyndrome #Sweeden “Is there something wrong with me? Why don’t I hate them?” In 1973, 21-year-old Elisabeth Oldgren posed this question to a psychiatrist in the wake of a robbery in Stockholm, Sweden, in which she and three other bank workers had been held hostage from Aug. 23-28. As the standoff neared an end, police were perplexed by the victims’ concern for their two captors: Despite cops’ orders that the hostages be the first to leave the bank vault in which they’d all been holed up, all four refused. ame> “Jan and Clark [the criminals] go first — you’ll gun them down if we do!” 23-year-old Kristin Ehnmark yelled back. The nationwide spectacle led to the genesis of the term “Stockholm syndrome,” in which a person held against their will comes to sympathize deeply with their abductor. In America, the phrase is more commonly associated with the 1974 case of Patty Hearst, the kidnapped heiress turned bank robber. It h...

Is it couple therapy, couple’s therapy, or couples therapy?

#BenCaldwell #MentaHealth #Psychology #HealthyRelationships  #Couples #Therapy #MFT By  Ben Caldwell ,  www.psychotherapynotes.com Okay, let’s not pretend this is an important question in the grand scheme of things. It is not. But for anxious types (like me) who want to make sure we’re using the right terminology, how do we describe that service of providing relationship therapy for two people?  Is it couple therapy, couple’s therapy, or couples therapy? I’m proud to offer a definitive, authoritative answer.* Read on. The evidence: AAMFT and state licensing boards The  American Association for Marriage and Family Therapy  seems content to not stake a flag in this debate. They manage to use all three variations in the  most recent issue of  Family Therapy Magazine . Heck, they’re all in the first seven pages. But we can draw some inferences from the organization’s title: While they don’t say “couple,” they do use the sin...
