Awesome time-lapse of the sun over a year

This amazing timelapse footage of the sun was filmed over a whole year by the NASA

It was released to mark the six year anniversary of Nasa's Solar Dynamics Observatory, which was set up to capture changes in the sun. A photo was taken every 12 seconds over the course of a year.

NASA’s Solar Dynamics Observatory (SDO) is always following the sun as it orbits the Earth. As part of its ongoing mission, the SDO captures high-resolution images of the sun at regular intervals, allowing scientists to monitor solar activity such as sun spots, solar flares, and coronal mass ejections. NASA’s multi-year mission just completed its sixth year of data collection and commemorated that milestone by releasing a stunning time-lapse video of the past year in review.

The six-minute video shows the sun over a period of just over a year, starting from January 1, 2015 and ending on January 28, 2016. The first half of the video shows the time-lapse with some celestial-inspired background music, while the second half explains the features and wavelengths that you are seeing. The ultra-high-definition images are shown on YouTube at a rate of approximately 30 frames per second with a resolution of 3,840 by 1,260 pixels. Each frame of the video corresponds to 2 hours of time on Earth. On its website, NASA also provides a downloadable version of the video that has a 59.94 fps frame rate with each frame representing one hour.

Earth Day is an annual event, celebrated on April 22, on which events are held worldwide to demonstrate support for environmental protection. It was first celebrated in 1970, and is now coordinated globally by the Earth Day Network, and celebrated in more than 192 countries each year.

In 1969 at a UNESCO Conference in San Francisco, peace activist John McConnell proposed a day to honor the Earth and the concept of peace, to first be celebrated on March 21, 1970, the first day of spring in the northern hemisphere. This day of nature's equipoise was later sanctioned in a Proclamation written by McConnell and signed by Secretary General U Thant at the United Nations. A month later a separate Earth Day was founded by United States SenatorGaylord Nelson as an environmental teach-in first held on April 22, 1970. Nelson was later awarded the Presidential Medal of Freedom Award in recognition of his work.^[While this April 22 Earth Day was focused on the United States, an organization launched by Denis Hayes, who was the original national coordinator in 1970, took it international in 1990 and organized events in 141 nations. Numerous communities celebrate Earth Week, an entire week of activities focused on environmental issues.

22nd March- WORLD WATER DAY

EVERY DROP CAN MAKE THE DIFFERENCE!

That we cannot live without water evrybody knows but are we really aware of the amount of water we waste every single day of 

our lives?

Saving water seems to be the key for our survival and this means everyone of us is responsible for that.

Have you ever thought about this when you're brushing your teeth or taking a shower or even when you don't drink all the water you drop in your glass?

World Water Day has been observed on 22 March since 1993 when the United Nations General Assembly declared 22 March as "World Day for Water".

This day was first formally proposed in Agenda 21 of the 1992 United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro, Brazil. Observance began in 1993 and has grown significantly ever since; for the general public to show support, it is encouraged for the public to not use their taps throughout the whole day. The day has also become a popular Facebook trend.

The UN and its member nations devote this day to implementing UN recommendations and promoting concrete activities within their countries regarding the world's water resources. Each year, one of various UN agencies involved in water issues takes the lead in promoting and coordinating international activities for World Water Day. Since its inception in 2003, UN-Water has been responsible for selecting the theme, messages and lead UN agency for the World Day for Water.

In addition to the UN member states, a number of NGOs promoting clean water and sustainable aquatic habitats have used World Day for Water as a time to focus public attention on the critical water issues of our era. Every three years since 1997, for instance, the World Water Council has drawn thousands to participate in its World Water Forum during the week of World Day for Water. Participating agencies and NGOs have highlighted issues such as a billion people being without access to safe water for drinking and the role of gender in family access to safe water. In 2003, 2006, 2009, and 2012 the UN World Water Development Report was launched on the occasion of the World Water Day.
