SpaceX's GO Navigator revokes the ship to Endeavor and pulls the compartment onto the deck shortly after landing. After a series of tests, the support team opened the Endeavor and began evaluating the health of Behknen and Hurley. This is the first time US spacecraft have landed in the sea in more than four decades. The most recent landing in July 1975 was when NASA astronauts Tom Stafford, Vance Brand and Deke Slayton finished the Apollo-Soyuz test project by landing in the Pacific Ocean.

Recently, researchers discovered that stars from SGR 1935 + 2154 emit both X-ray signals and radio waves. The discovery of the ESA space telescope, a device floating at an altitude of nearly 153,000 km above Earth to track radiation in the universe, is the first observation to reveal the relationship between magnetic stars and radio waves . The results of the study were published July 27 in the Astrophysical Journal Letters.

The huge dust cloud caused the Caribbean sky to turn gray on its way to America with unprecedented size and density over the past half century. The scene in the Caribbean countries is blind due to the dust. Video: Guardian. Air quality in most of the Caribbean is "dangerous" and experts nicknamed the cloud of Godzilla, while also advising people to stay indoors and use an air purifier if available. "This is the most significant event in the last 50 years," said Pablo Méndez Lázaro, an environmental health specialist at the University of Puerto Rico. "The situation is very dangerous in many Caribbean islands". Lázaro, who is working with NASA to develop a Sahara dust storm warning system, said the dust density in recent days was so high that it could have harmful effects on healthy people.

The Greater Adria continent is about the size of Greenland that existed hundreds of millions of years ago after separating from the Gondwana supercontinent. Today's continents on Earth come from the Pangea supercontinent. Pangea split into two smaller parts, Laurasia in the north and Gondwana in the south. Tectonic plates facing northward later form Europe, Asia and North America. The southward drift forms Africa, Antarctica, South America and Australia. The researchers discovered the 8th continent separating from Gondwana named Greater Adria.

NEW ZEALAND The first time the researchers published a map depicting geological and tectonic features of Zealandia, the continent sank into the sea 8 million years ago. Once in the same region as Antarctica and Australia, the missing continent of Zealandia split 85 million years ago, sank into the sea and was inundated for most of the centuries. The GNS Science Research Institute in New Zealand, announced two new maps and an interactive website on June 22. Maps depicting the shape of the sea floor and the tectonic characteristics of Zealandia reveal the origin of the continent. The map also helps explain the formation of volcanoes, sedimentary basins and many other geological features of New Zealand.

Steve Jobs changed the world with crazy expensive products, while Elon Musk was selling human dreams at unbelievably cheap prices. Silicon Valley needs a spiritual leader. Steve Jobs lit that creative spirit 40 years ago. Then Bill Gates, Jeff Bezos, Mark Zuckerberg, two Google founders Larry Page and Sergey Brin ... took over the torch. But Jobs and these people were not in the same group. The father of the iPhone is the "real product", while the technology CEOs in Silicon Valley belong to the Internet generation. Elon Musk is different. The "most controversial" billionaire "technology village is changing the world with tangible products such as electric cars, rockets and satellites. From Steve Jobs to Elon Musk When the first generation iPhone came out, the media called it "God's phone". Nobody calls SpaceX's Falcon 9 "rocket of the gods" or something like that. But it opened up a whole new perspective to the human world. It took 13 years for the world of technology to witness a landmark product.

Astronomers found a black hole 1,000 light-years from Earth to form a system with two stars. The new black hole is in the southern constellation Telescopium, along with two companion stars bright enough to see with the naked eye. But you won't see the black hole itself, because it has gravity so strong that nothing can escape, including light. The team, led by astronomer Thomas Rivinius at the Southern European Observatory, discovered a black hole while studying a system they thought was a binary star system. They used a 2.2-meter MPG / ESO telescope at the La Shilla Observatory in Chile to observe the HR 6819 in a broader study of binary star systems. When analyzing the data, the team suddenly realized that the third object hidden in the system was a black hole.

Scientists think the tension between the two magnetic fields below Canada and Siberia is the reason why the north magnetic field of the Earth moves. A team at the University of Leeds found that the pole's magnetic north position is controlled by two magnetic fields, one below Canada and one below Siberia. They create a tension effect that determines the position of the magnetic pole, according to lead researcher Dr Phil Livermore.

Chinese experts have been to the camp at the foot of the mountain in Tibet since March 2 to prepare to measure the height of Mount Everest, SCMP reported on May 1. Mount Everest is in the Himalayas, on the border between Nepal and China. The two countries have long debated how to determine the height of Mount Everest, whether or not to calculate the peaks or the peaks. In 2005, a Chinese expedition conducted a measurement of the height of the rock peak and the snow cover. As a result, China claims the peak height of 8,844.43 meters is the most accurate data up to that point.

As expected, X-37B aircraft will take off from Cape Canaveral air base in Florida, USA, on the back of Atlas V liquid fuel rocket on 16/5, bringing a series of equipment to conduct 3 experiments. different. Experiments include converting the sun's energy into radio frequency microwave energy to send to Earth and supplying it to various facilities, including military bases. In addition to harnessing energy from the Sun, the aircraft will also evaluate the reaction of materials in space and the impact of radiation on seeds for NASA. This unmanned aircraft has performed many top secret missions for the US military, allowing testing of new technology in space environment.
