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.
