The destruction of a planet may sound like the stuff of science fiction, but a team of astronomers has found evidence that this may have happened in an ancient cluster of stars at the edge of the Milky Way galaxy.
Using several telescopes, including NASA’s Chandra X-ray Observatory, researchers have found evidence that a white dwarf star – the dense core of a star like the Sun that has run out of nuclear fuel – may have ripped apart a planet as it came too close.

April 15, which was baseball’s opening day in 1947, has now come to commemorate Jackie Robinson’s memorable career and his place in history as the first black major league baseball player in the modern era. He made history with the Brooklyn Dodgers (now the Los Angeles Dodgers) and he was inducted to the Baseball Hall of Fame in 1962.

The mission is the company’s sixth cargo delivery flight to the station through NASA’s Commercial Resupply Services contract. Dragon’s cargo will support approximately 40 of the more than 250 science and research investigations that will be performed during Expeditions 43 and 44, including numerous human research investigations for NASA astronaut Scott Kelly’s one-year mission in space.

The space station’s solar arrays contain a total of 262,400 solar cells and cover an area of about 27,000 square feet (2,500 square meters) — more than half the area of a football field. A solar array’s wingspan of 240 feet (73 meters) is longer than a Boeing 777’s wingspan, which is 212 feet (65 meters). Altogether, the four sets of arrays can generate 84 to 120 kilowatts of electricity — enough to provide power to more than 40 homes. The solar arrays produce more power than the station needs at one time for station systems and experiments. When the station is in sunlight, about 60 percent of the electricity that the solar arrays generate is used to charge the station’s batteries. At times, some or all of the solar arrays are in the shadow of Earth or the shadow of part of the station. This means that those arrays are not collecting sunlight. The batteries power the station when it is not in the sun.

This photograph of the Mission Operations Control Room in the Mission Control Center at the Manned Spacecraft Center (now Johnson Space Center), Houston, was taken on April 13, 1970, during the fourth television transmission from the Apollo 13 mission. Eugene F. Kranz (foreground, back to camera), one of four Apollo 13 flight directors, views the large screen at front as astronaut Fred W. Haise Jr., Lunar Module pilot, is seen on the screen.
