Using NASA's Chandra X-ray Observatory, a team of British astronomers has concluded that the supermassive black hole at the center of the Milky Way could be devouring asteroids, which would explain the frequent observed eruptions (one at day) from the center of our galaxy.

Two years ago, scientists at the National Center for Atmospheric Research in Boulder, Colorado, published a study that found inconsistencies between satellite observations of heat on Earth and measurements of ocean warming, which suggested there was "wasted energy" in the planet system. Where was that energy going?

A new high-definition image of the Earth, at 8,000 x 8,000 pixels, has been taken by NASA's latest observation satellite, the Suomi NPP, located 824 kilometers from the planet's surface. Named after Verner E. Suomi, a pioneer in the use of satellites, the instrument captures a complete image of the planet every day. The image consists of several photographs of the Earth taken on January 4, 2012.

Space debris has grown by 1.37 percent in the last year compared to 2010 levels, and there are 16,117 debris orbiting the Earth, from intact rockets and launchers to the remains of these damaged devices, according to the last one. quarterly report of the NASA Orbital Debris Program Office.

The European Space Agency (ESA) has just released the songs that have accompanied astronauts since manned space flights began. The first song heard was a Hawaiian tune aboard the Gemini 7 spacecraft in December 1965. A few years later, the Apollo astronauts brought with them the first cassette tapes of songs like Dvorak's New World Symphony. , the songs of The Beatles, Simon and Garfunkel, of the group The Moody Blues.

Thanks to new maps produced by the Lyman Alpha Cartography Project (LAMP), aboard NASA's Lunar Reconnaissance Orbiter probe, hitherto unknown features of regions at the north and south poles of the Moon have been discovered. in perpetual darkness.

It is the largest group of galaxies, the hottest, and the one that generates the most X-rays of all those discovered so far. And it has been found by US and Chilean astrophysicists with the help of the Atacama Cosmological Telescope and NASA's Chandra X-ray Observatory. Officially known as ACT-CL J0102-4915, the group of galaxies, located more than 7,000 million light years from Earth, has been nicknamed "El Gordo" by its discoverers.

"Apply to explore with us. Fly with NASA, where the sky is not the limit." This is how the campaign that the agency has launched through the Internet and YouTube to recruit new astronauts is announced. The requirements: be American, have a bachelor's degree in engineering or science, and more than three years of work experience.
