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.
The Greenhouse Gases Bulletin produced annually by the World Meteorological Organization (WMO) reveals that in 2010 a new record was reached in the concentrations of these elements in the atmosphere. This increase was mainly caused by carbon dioxide.
The asteroid 2005 YU55, which was once classified as a threat to Earth, will pass 324,600 kilometers from the planet on November 8. According to experts, there is no danger of collision, however, being a distance shorter than the orbit of the Moon, NASA will follow the trajectory of the body until it moves away.
An international team of astronomers has identified in Comet Hartley 2, belonging to the Kuiper Belt, water with the same chemical composition as the Earth's oceans. The finding supports the theory that comets brought to our planet a significant portion of the water from the oceans, which scientists estimate formed about eight million years after Earth itself.
Like many of its inhabitants, the Earth is increasing in size right in the center of its "body", according to a new study. This "waist widening" of the planet is due to the melting of the Greenland and Antarctic ice sheets, the authors conclude.
Most near-Earth asteroids are egg-shaped, with eccentric orbits that move directly through the inner solar system. However, a new object discovered by NASA's WISE infrared telescope, named 2010 SO16, is different. Its orbit is almost circular, so it cannot get close to any other planet in the solar system except Earth.
Next Saturday the 19th look at the sky at dusk. The Moon will be located 356,575 kilometers from Earth, that is, 7% closer to the average distance that separates our planet from its satellite (382,900 kilometers). This will make it look much larger in the Northern Hemisphere.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
