Pleiades: The Seven Sisters (Messier 45)

Jean-Dominique Maraldi The first known globular cluster, now called M22 , was discovered in by Abraham Ihle , a German amateur astronomer. When William Herschel began his comprehensive survey of the sky using large telescopes in there were 34 known globular clusters. Herschel discovered another 36 himself and was the first to resolve virtually all of them into stars. Beginning in , Harlow Shapley began a series of studies of globular clusters, published in about 40 scientific papers. He examined the RR Lyrae variables in the clusters which he assumed were Cepheid variables and used their period—luminosity relationship for distance estimates. Later, it was found that RR Lyrae variables are fainter than Cepheid variables, which caused Shapley to overestimate the distances of the clusters. Of the globular clusters within the Milky Way, the majority are found in a halo around the galactic core, and the large majority are located in the celestial sky centered on the core. In , this strongly asymmetrical distribution was used by Shapley to make a determination of the overall dimensions of the galaxy. By assuming a roughly spherical distribution of globular clusters around the galaxy’s center, he used the positions of the clusters to estimate the position of the Sun relative to the galactic center.

A Guide to the Night Sky Pleiades: The brightest stars in the cluster represent the Pleiades, the Seven Sisters in Greek mythology, and their parents, the nymph Pleione and the Titan Atlas. Messier 45 is one of the nearest star clusters to Earth. Its brightest stars lie at a distance between and light years. The cluster is mostly composed of hot, blue, highly luminous stars belonging to the spectral class B with an estimated age under million years.

It is the easiest star cluster to find in the sky, mainly because of its brightness and size, and it is well known in many different cultures and mythologies. The earliest images of the Pleiades cluster date all the way back to the Bronze Age.

Larger settlements like Jericho arose along salt and flint trade routes. Northern Eurasia was resettled as the glaciers of the last glacial maximum retreated. World population was at a few million people, likely below 5 million.

Hopefully I can make people aware. Miss Price contacted Durham County Council’s environmental health department and was referred to pest control ‘I don’t think the health and safety procedure is up to scratch for bringing produce in from other countries.

They are known as the wandering spider because they do not build webs, but instead walk the jungle floor at night looking for prey. Brazilian wandering spiders are nocturnal, and so find places to hide during the day.

Relationships per se are difficult. Two individuals come together — attraction, lust, love, personality styles, personal and family histories, attachment, and lifestyles collide — and there you are in the middle of a daring, challenging, and steamy relationship. Remember we all have personality traits, which does not make us personality disordered. Notoriously famous personality disorders discussed in films, courts, and domestic disputes are all part of the dramatic-erratic cluster: The film Fatal Attraction quite an excellent performance by Glenn Close and the recent court case of Jodi Arias come to mind.

This is why they are so dangerous, because they hide in houses and cars, where they are easily disturbed by humans.

Updated 8 January c Introduction In a related article on geologic ages Ages , we presented a chart with the various geologic eras and their ages. In a separate article Radiometric dating , we sketched in some technical detail how these dates are calculated using radiometric dating techniques. As we pointed out in these two articles, radiometric dates are based on known rates of radioactivity, a phenomenon that is rooted in fundamental laws of physics and follows simple mathematical formulas.

Dating schemes based on rates of radioactivity have been refined and scrutinized for several decades. The latest high-tech equipment permits reliable results to be obtained even with microscopic samples. Radiometric dating is self-checking, because the data after certain preliminary calculations are made are fitted to a straight line an “isochron” by means of standard linear regression methods of statistics. The slope of the line determines the date, and the closeness of fit is a measure of the statistical reliability of the resulting date.

My friend shared with me later just how anxiety-provoking this new relationship has become. After a few weeks, they’ve officially entered that awkward phase where uncertainty is king, and I’m sure each member of the couple is spending a great deal of time talking about the relationship with their respective friends. Oh, the drama that new love brings! The beginning of a new relationship is scary because you don’t really know the person you’re dating, so you can’t be sure what you’re going to get.

In other words, you’re investing in a relationship based purely on faith , or your hope that this new person will be good for you. But let’s all admit what a risk it is to start falling in love! Can you imagine taking a thousand dollars and putting it into a stock that you don’t know much about? If you only knew a few details about the company you were investing in, you’d probably decide not to invest in it. Because it would feel too risky.

Yet in relationships, the pull toward a new lover is so strong that it feels as if you really don’t have a choice at all. If you like the person and want to get to know them better, you have no choice but to proceed.
