Voyager 1 reaches edge of our solar system

Scientists with the U.S. space agency NASA say the Voyager 1 spacecraft, launched 33 years ago, is on the edge of our solar system where there is no outward motion of solar wind.

NASA says the spacecraft is now more than 17 billion kilometers from the sun and has reached an area where the velocity of the solar wind - the hot, ionized particles flowing outward from the sun - has diminished to near zero.

The scientists say Voyager is preparing to exit the heliosheath, the turbulent outer shell of the sun's sphere of influence. In about four years, the spacecraft will fully reach interstellar space and come under the influence of another star system.

Voyager 1 was launched in 1977 and throughout its journey, has sent back data about the planets in our solar system and the solar wind that is helping to push it through space. 

A separate spacecraft, Voyager 2, was launched a month before Voyager 1. It is now about 14 billion kilometers from the sun, traveling at a different path and different speed than Voyager 1.

On the nights of August 11 and 12 2009, a prolific meteor shower known as the Perseids, passed over the Earth. The shower is visible from mid-July each year, but the peak in activity, when 60 or more meteors can be seen an hour, is usually mid-August. In 2009, this happened on August 11 and 12.

Earth will hide the Moon tonight

The wonders of nature keep on surprising in August. After the solar eclipse from August 1 and the meteor shower on august 12 and 13, in the night of August 16 a partial lunar eclipse will be observed. It will begin at 10.36 pm EEST and will end on 1.45am on August 17.It is the second of only two lunar eclipses in 2008 and will be visible by most of Eastern Europe and Africa, and a large portion of Western and Central Asia and India. Parts of Australia will see the eclipse begin before

Meteor shower for the Earth tonight

Stars will be raining tonight and on the night of August 13, scientists have promised. The Perseid meteor shower takes place when Earth enters the outskirts of a cloud of debris from Comet Swift-Tuttle. The comet dust enters earth atmosphere, heats to luminosity and gives the impression of falling stars. Depending on their chemical composition, the meteors burn in different colours. Rarely do such meteors reach the

The magic disappearing sun

IN a year's time, a total solar eclipse will traverse a path near to the position from which you read this article. Okay, so Antalya, Turkey may not generally be classified as `near' to Bulgaria, but when you consider the cosmic distances that the sun and moon have to travel in order to graciously align before the earth, Turkey doesn't seem so far away.
