After many false alarms and postponements, finally the awaited moment has arrived. The NASA spacecraft Voyager 1 is officially the first human to enter interstellar space. The probe, which has switched off the 36th candle, is approximately 19 billion kilometers from the Sun. Source: www.jpl.nasa.gov The new data just published by Science reveal that Voyager 1
Searching and researching the sky

Exoplanet hunters are not ever satisfied. At the University of Arizona, they are developing a new type of search that could greatly improve the localization of terrestrial planets with advantageous conditions to biological life, like water in a liquid state. This artist’s conception shows NASA’s Wide-field Infrared Survey Explorer, or WISE, mapping the whole
The existence of a third star in the Fomalhaut system

It is the 18th brightest star in our night sky and one of the few stars possess an extended circumstellar disk of gas and dust. Of course, it is the main star in the constellation Piscis Austrinus and it is out of the ground about 25 light years. Let’s talk about Fomalhaut, at the center
There was once a habitable planet…

Could be that good, but we’ve already played. The planet or planets, which clearly orbited around the star GD 61, had probably all the characteristics we look for in a planet that is suitable to host life: Rocky surface and abundant presence of water. The area of the solar system (or any planetary system) where
Our bubble in the universe

One of the most shocking results of the past few years certainly refers to the discovery of the accelerating expansion of the universe. It has also been given the Nobel Prize for this achievement, accomplished through the observations of types of supernovae in galaxies far enough (beyond our local group).

The power of GAIA

In an attempt to answer one of the fundamental questions of mankind “Are we alone in the universe?” The planets and stars nearest to us, within a hundred light years from the Sun, are the most obvious and immediate sample to be analyzed. The interdisciplinary field of extrasolar planets with increasingly rapid expansion has recently
Juno travels to Jupiter after a fly-by very “safe”

In the close passage of the Juno probe, everything went well; resulted with some unexpected thrill. Wednesday, 9 October the mission NASA has performed his gravity assist approached land up to a distance of just 559 miles from us before returning to the route to Jupiter, which will reach in 2016. From the point of
Our planet would be doomed if it were not for the Moon

What if the moon were at 420 kilometers away from Terra? As it would seem? And what would happen to our planet? It’s a condition almost impossible, because our natural satellite tends to move away and not to approach, but there are those who, on the web, tried to imagine how the Moon would be
The cosmic lens to the edge of the universe
© Afrim Constantin –
Today it is the farthest ‘ telescope ‘ known that nature has made available, but it is not made of glass, mirrors and gears. Its lens is a galaxy far away, at 9.4 billion light years from us, so that its mass has allowed deflecting and amplifying light from another galaxy placed exactly behind it,
