An all-girl team from Afghanistan joined an international robotics competition in Washington. Their experience was challenging as they had problems even before stepping foot in America. The girls applied for their visas twice but their applications were not accepted. Fortunately, they were still able to go to the U.S. with the help of President Donald Trump. The Department of Homeland Security allowed the Afghan girls to enter the U.S. for a short time even without visas. The Department officials said that they allowed these girls because their visit would benefit the public.

During the competition, the students got the chance to meet the Deputy Secretary of State, John Sullivan. They were also able to speak with the New Hampshire Senator Jeanne Shaheen. She expressed her happiness for the students as they had overcome all the challenges.

The Barcelona Soccer star Lionel Messi finally marries his girlfriend, Antonela Roccuzzo, after many years of being together. Their wedding took place in the town of Rosario, Argentina. The couple met through Messi’s friend, Lucas Sacaglia, who happened to be Roccuzzo’s cousin. Their relationship was kept a secret until they came out as a couple before the 2010 World Cup.

Messi could have chosen to get married in one of the best places in the world, yet he still chose Rosario where he was born and grew up. Some members of the Barcelona soccer team along with 250 guests attended the wedding. Messi’s fans watched on big screens as they were not allowed to go to the hotel where the wedding took place. The romantic event was even called “The Wedding of the Century” by a local newspaper in Argentina.

Ex-President Barack Obama has become more popular because of his tweet about an attack in Virginia. The most liked tweet was a line from Nelson Mandela’s book, “Long Walk to Freedom.” It said, “No one is born hating another person because of the color of his skin or his background or his religion. People must learn to hate, and if they can learn to hate, they can be taught to love, for love comes more naturally to the human heart than its opposite.”

The line was divided into three tweets. One of them has a photo of Obama greeting children through a window in Maryland.

A Twitter staff said, the most liked tweet before that was from Ariana Grande about an attack in her concert. It was beat by Obama’s tweet which was liked more than three million times.

Scientists from Brown University have discovered that there is a good bit of water inside the moon. According to the associate professor at Brown University, they found water trapped in glass beads. These beads are from the ashes and rocks of volcanic eruptions. They have also mentioned that almost all of the volcanic materials show signatures of water which means that a large part of the moon is wet.

In 2008, the volcanic beads that were brought back by the Apollo in 1971 and 1972 were examined. They found crystalline formations that contain water. However, they were unsure if these samples represented either the whole moon or just a small part of it. To confirm this, they studied the samples again. They were able to gather more evidence to prove that the volcanic materials were spread all over the moon.

Some people believe that ancient Egyptians knew the principles of flying. With the discovery of the Saqqara Bird in 200 B.C, people thought of it as an actual aircraft model because ancient Egyptians often put models of actual inventions in tombs. A model based on the Saqqara bird’s design was tested and was discovered that it could have flown. Thousands of years after that, a part of an ancient writing system that seems to be a helicopter was seen in the Temple of Seti The First built at around 1280 B.C. However, what ancient Egyptians knew about aircraft remains unknown.

The Quimbaya civilization which existed halfway across the world is what is now called South America. They are popular for their gold antiques. Among them was an airplane-like antique, which was possibly a model of a bird or an insect. However, some people believed that it can fly so in the 1990’s, it was tested with an engine and it flew above the ground.

About the same time with the Quimbaya civilization, the Mayan civilization existed. Some people thought that the ancient Mayans are familiar with space travel because of Pakal I’s tomb. Pakal I ruled from A.D. 615 to 683 and was buried in a spaceship-like tomb. Until now, the mystery behind the ancient models has not been solved.
