Voyager 1 is not heading towards any particular star, but in about 40,000 years it will pass within 1.6 light years of the star AC+79 3888 in the constellation Camelopardalis. That star is generally moving towards our Solar System at about 119 kilometers per second.
RUN!! there is a star coming for us!!! lol... anyway, that is a very long time to wait, we will be gone by then. And that star is a lot closer then it looks, because what we see could have happened hundreds, thousands or even millions of years ago. We see it after it happens due to the speed of light being limited.
Voyager 2 is currently transmitting scientific data at about 160 bits per second. Information about continuing telemetry exchanges with Voyager 2 is available from Voyager Weekly Reports.
As of April 27, 2011, Voyager 2 is traveling at 15.464 km/s, is 8.8 billion miles away or 94.913AU from the Sun, at ?55.01° declination and 19.905 h right ascension, and is also at an Ecliptic Latitude of -33.6 degrees, placing it in the constellation Telescopium as observed from Earth.
That is fast. It would be interesting to send a probe into... nothing, as in not through our galaxy, but headed for another. We would be able to observe if there are many objects out in the nothingness, and it would be a start for galaxy exploration. the main problem in that is fuel.... there isn't much light from stars out there.
