Sensible Sunrise


All astronomers are receiving to know their neighbors improved. Our Sun lies within a spiral arm of our Milky Way galaxy, about two thirds of the way in the opposite direction to the center. Recently, the satellite Wide-field Infrared Survey Explorer, or WISE, NASA has sought a new group of stars close to home: the family coldest brown dwarf star "failed". Now, just when scientists are "finding and greet" the new neighbors, WISE has a surprise in the room: there are many fewer stars brown around us predicted.

Since every two years the Specula Vatican organizes some international summer courses on astronomy. This is the thirteenth edition. The information was released by Vatican Radio, whose team interviewed Father Gabriel Funes, director of the Astronomical Observatory of the Holy See, located in Castel Gandolfo. The bishop confirmed the Vatican agency that there's interest, especially students from Latin America.

Sunrise at Uranus and Venus


Sky watchers will have an asymmetrical opportunity to spot the planet Uranus, because it will be located very close to the brilliant planet Venus in the sunrise sky.
You can easily spot Venus as the brightest article in the sky just before sunrise, but it will be better to be up a little earlier just as Venus clears the eastern horizon, so that the sky will be as dark as possible. This will help you to spot tiny Uranus, just within range of the naked eye under perfect conditions, but most of the time requiring binoculars or a small telescope to spot.

A strange hot spot on a planet from outside our solar system


The Spitzer Space Telescope NASA has exposed a strange point of heat in a planet outside our solar system in the Andromeda group, 44 light years from the Earth. The planet, Upsilon Andromeda, is a massive such as 'hot Jupiters', named for its high temperatures and gas formation. The strange thing, the mystery that scientists cannot manage to explain, is that this extraordinary heat zone is located in a part of the planet in which there should be, away from exposure to the star, which contradicts all theories known.

The discovery of an exoplanet


A reacharger group of European astronomers has announced the discovery of an exoplanet particular. Is larger than Jupiter and may be gaseous, so it does not look like Earth. But what is its origin awareness. In fact, that distant world was not formed in our galaxy, but entered it, along with its star, about 9,000 million years. The finding is published this week in Science.
"The discovery is very exciting, says Rainer Klement, one of the authors of the study, for the first time, astronomers have detected a planetary system in a stellar group of extragalactic origin.

Next two satellites are prepared for launch


The next two satellites in the Galileo European navigation have been subjected to an aggressive vacuum conditions and extreme temperatures in preparation for launch, scheduled for September 28. The fourth satellite Galileo completed earlier this month 20 days of thermal vacuum tests on the location of Thales Alenia Space on the outskirts of Rome, Italy. The third had passed the same test a month earlier.

The primary survey of stars and the finding of other 'Earths', amazing closer


The primary survey of stars close to the Sun with Earth-like planets are faster to creature a actuality thanks to the spectrometer calibration technique, a technology used to calculate the speed of a star and make measurements with precision and accuracy "unprecedented." This has been noted scientists of the Max Planck, the European Southern Observatory, who have tried this technique to trace the orbit of an exoplanet discovered and which revolve around the star HD75289 and the results published in Nature.
