Scientists have found evidence of 'flowing liquid water' exists on Mars during summer time on the Red Planet as the National Aeronautics and Space Administration said Monday morning.

According to Ojah, now a PhD candidate at the Georgia Institute of Technology and the lead author of the study, told to the Al Jazeera that "water does exist on Mars". He also said "We found evidence of water activity in hydrated salts on Mars."

NASA announce that "Our findings strongly support the hypothesis that recurring slope lineae form as a result of contemporary water activity on Mars,"

There is a total eclipse of the moon on the night of September 27-28, 2015. It happens to be the closest supermoon of 2015. It’s the Northern Hemisphere’s Harvest Moon, or full moon nearest the September equinox.

It’s the Southern Hemisphere’s first full moon of spring. This September full moon is also called a Blood Moon, because it presents the fourth and final eclipse of a lunar tetrad: four straight total eclipses of the moon, spaced at six lunar months (full moons) apart. Phew!

The White House is the official residence and principal workplace of the President of the United States, located at 1600 Pennsylvania Avenue NW in Washington, D.C. It has been the residence of every U.S. president since John Adams in 1800.

The house was designed by Irish-born James Hoban and built between 1792 and 1800 of white-painted Aquia Creek sandstone in the Neoclassical style. When Thomas Jefferson moved into the house in 1801, he (with architect Benjamin Henry Latrobe) expanded the building outward, creating two colonnades that were meant to conceal stables and storage.

Because of crowding within the executive mansion itself, President Theodore Roosevelt had all work offices relocated to the newly constructed West Wing in 1901. Eight years later, President William Howard Taft expanded the West Wing and created the first Oval Office which was eventually moved as the section was expanded. In the main mansion, the third-floor attic was converted to living quarters in 1927 by augmenting the existing hip roof with long shed dormers. A newly constructed East Wing was used as a reception area for social events; Jefferson's colonnades connected the new wings. East Wing alterations were completed in 1946, creating additional office space.

The flag of the United States of America, often referred to as the American flag, is the national flag of the United States.

The 50 stars on the American flag represent the 50 states of the United States of America, and the 13 stripes represent the thirteen British colonies that declared independence from the Kingdom of Great Britain, and became the first states in the Union.  Nicknames for the flag include the Stars and Stripes, Old Glory, and the Star-Spangled Banner.
