Solar Eclipse Science Google Doodle

A solar eclipse (as seen from the planet Earth) is a type of eclipse that occurs when the Moon passes between the Sun and Earth, and when the Moon fully or partially blocks (“occults”) the Sun. 

This can happen only at new moon when the Sun and the Moon are in conjunction as seen from Earth in an alignment referred to as syzygy. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun is obscured

There are two kinds of eclipses. lunar and solar. In a solar eclipse, the moon comes between Earth and the Sun, casting a shadow on the surface of Earth.A lunar eclipse occurs when Earth comes between the sun and a full moon, blocking light from the sun and casting a shadow on the surface of the moon.

Eclipses affect animals too: the sudden darkness and resulting drop in temperature during a total solar eclipse can cause critters to behave as it it were dusk.

Skywatchers on the American continent today are in for a special astronomical treat: front row seats to a total solar eclipse. An eclipse occurs when the moon passes between the sun and the earth, blocking the light of the sun from reaching us. 

While eclipses aren’t rare, a total eclipse, when viewers from Earth are at the very center of the moon’s shadow, only happens once every 18 months. To see one requires you to be in just the right place on earth, and a total eclipse in the same location only happens every 375 years on average.

He was a fixture in media discourse in the late 1960s, though his influence began to wane in the early 1970s

McLuhan also started the journal Explorations with anthropologist Edmund "Ted" Carpenter

He never fully recovered from the stroke and died in his sleep on December 31, 1980.

Cassini Spacecraft Dives Between Saturn and its Rings in Today's Google Doodle

Cassini–Huygens is an unmanned spacecraft sent to the planet Saturn. It is a Flagship-class NASA–ESA–ASI robotic spacecraft.

Cassini is the fourth space probe to visit Saturn and the first to enter orbit, and its mission is ongoing as of April 2017.

It has studied the planet and its many natural satellites since arriving there in 2004

Google celebrate Cassini Spacecraft Dives Between Saturn and its Rings! with doodle

Cassini is currently planned to be destroyed by diving into the planet's atmosphere on September 15, 2017, when it will beam its last batch of images.

Cassini was developed simultaneously with the Comet Rendezvous Asteroid Flyby (CRAF) spacecraft, but budget cuts and project rescopings forced NASA to terminate CRAF development to save Cassini. 

Cassini Size: 6.7 metres high by 4.0 metres wide and Weight: 5712 kilograms

Powered by: Nuclear thermoelectric generators, packed with 30 kilograms of plutonium

Launched on: 15 October 1997

Distance travelled on journey to Saturn: 3.5 billion kilometres

The Cassini space probe performed two gravitational-assist flybys of Venus on April 26, 1998, and June 24, 1999. 

These flybys provided the space probe with enough momentum to travel all the way out to the asteroid belt. At that point, the Sun's gravity pulled the space probe back into the inner Solar System

Google doodle honors Ghanaian entrepreneur Esther Afua Ocloo

Esther Afua Ocloo (April 18, 1919, Peki Dzake - February 8, 2002) was a Ghanaian entrepreneur and pioneer of microlending. She was born Esther Afua Nkulenu.

She was one of the founders of Women's World Banking in 1976, with Michaela Walsh and Ela Bhatt, and served as its first chair of trustees. She received the 1990 Africa Prize for Leadership.

April 18, 2017 the search engine Google shows a Doodle for 98th Birthday of Esther Afua Ocloo, in few countries. The Google Doodle shows Esther Afua Ocloo empowering the women of Ghana with the tools to improve their lives and communities.

As both an entrepreneur and an advocate for microlending, “Auntie Ocloo” worked tirelessly to help others like her succeed. Esther Afua Ocloo had only six shillings to her name — less than a dollar — when she made and then sold her first jar of marmalade as a teenager in the 1930s.

Esther was determined to expand her livelihood of making marmalade and orange juice, but she needed a loan to increase production, and credit was hard to come by for poor women. It took persistence and a supply contract to secure the money to start her company, Nkulenu Industries.

After traveling to England to learn the latest techniques in food processing, Esther returned home and shared those skills with other Ghanaian women. Perhaps more importantly, she taught them everything she knew about starting and running a business, which put more money in their pockets. She made such an impact that in 1975 she was invited to the first U.N. World Conference on Women.

Esther and other advisors knew that lending money to women could have a ripple effect, improving the prosperity and health of the women as well as their communities. But because they lacked collateral, low-income women were often ignored by banks. So in 1979, Esther helped found and became Chairman of the Board of Directors of Women’s World Banking, which provides millions of low-income women with the small loans needed to reach their financial goals.

Afua Nkulenu was born in the Volta Region to George Nkulenu, a blacksmith, and his wife Georgina, a potter and farmer

She was a founding member of religious groups such as the Evangelical Presbyterian Church in Madina (a suburb of Accra) and the Unity Group of Practical Christianity (Ghana). She also assisted in forming a women’s group in the E.P Church known as Bible Class with the aim of studying the bible and home management.

She served on the synod committee of the E.P Church for 12 years.
