William Herschel

Frederick William Herschel, was a British astronomer and composer of German origin, and brother of fellow astronomer Caroline Herschel, with whom he worked. Born in the Electorate of Hanover, Herschel followed his father into the Military Band of Hanover, before migrating to Great Britain in 1757 at the age of nineteen.

Herschel constructed his first large telescope in 1774, after which he spent nine years carrying out sky surveys to investigate double stars. The resolving power of the Herschel telescopes revealed that the nebulae in the Messier catalogue were clusters of stars. Herschel published catalogues of nebulae in 1802 (2,500 objects) and in 1820 (5,000 objects). In the course of an observation on 13 March 1781, he realized that one celestial body he had observed was not a star, but a planet, Uranus. 

This was the first planet to be discovered since antiquity and Herschel became famous overnight. As a result of this discovery, George III appointed him Court Astronomer. He was elected as a Fellow of the Royal Society and grants were provided for the construction of new telescopes.

Herschel pioneered the use of astronomical spectrophotometry as a diagnostic tool, using prisms and temperature measuring equipment to measure the wavelength distribution of stellar spectra. Other work included an improved determination of the rotation period of Mars, the discovery that the Martian polar caps vary seasonally, the discovery of Titania and Oberon (moons of Uranus) and Enceladus and Mimas (moons of Saturn). In addition, Herschel discovered infrared radiation. Herschel was made a Knight of the Royal Guelphic Order in 1816. He was the first President of the Royal Astronomical Society when it was founded in 1820. He died in August 1822, and his work was continued by his only son, John Herschel.

The heliosphere is the bubble-like region of space dominated by the Sun, which extends far beyond the orbit of Pluto. Plasma “blown” out from the Sun, known as the solar wind, creates and maintains this bubble against the outside pressure of the interstellar medium, the hydrogen and helium gas that permeates the Milky Way Galaxy. The solar wind flows outward from the Sun until encountering the termination shock, where motion slows abruptly. The Voyager spacecraft have explored the outer reaches of the heliosphere, passing through the shock and entering the heliosheath, a transitional region which is in turn bounded by the outermost edge of the heliosphere, called the heliopause. The shape of the heliosphere is controlled by the interstellar medium through which it is traveling, as well as the Sun and is not perfectly spherical. The limited data available and unexplored nature of these structures have resulted in many theories. The word “heliosphere” is said to have been coined by Alexander J. Dessler, who is credited with first use of the word in the scientific literature.

In honor of World Elephant Day, we present you with 12 little known facts about one of our favorite creatures…in GIFs, of course.

1. Elephants know every member of their herd and are able to recognize up to 30 companions by sight or smell. 

2. They can remember and distinguish particular cues that signal danger and can recall locations long after their last visit.

3. An elephant’s memory is not limited to its herd, nor is it limited to its species. In one instance, two circus elephants that performed together rejoiced when crossing paths 23 years later. Elephants have also recognized humans that they once bonded with after decades apart. 4. 

4. The elephant boasts the largest brain of any land mammal as well as an impressive encephalization quotient (the size of the animal’s brain relative to its body size). The elephant’s EQ is nearly as high as a chimpanzee’s.

5. The elephant brain is remarkably similar to the human brain, with as many neurons and synapses, as well as a highly developed hippocampus and cerebral cortex.

6. Elephants are one of the few non-human animals to suffer from post-traumatic stress disorder.

7. Elephants are creative problem solvers. 

8. Don’t try to outsmart an elephant! They have an understanding of basic arithmetic and can even keep track of relative quantities.

9. Elephants communicate using everything from body signals to infrared rumbles that can be heard from kilometers away. Their understanding of syntax suggests that they have their own language and grammar. 

10. Elephants can recognize 12 distinct tones of music and recreate melodies.

11. Elephants are the only non-human animals to mourn their dead, performing burial rituals and returning to visit graves. 

12. Elephants are one of the few species who can recognize themselves in the mirror.

Given what we now know about elephants, and what they continue to teach us about animal intelligence, it is more important than ever to make sure that these magnificent creatures do not vanish.
