| This time-lapse movie is made from a series of pictures taken by NASA's
Hubble Space Telescope. It shows astronomers that young stars and their
surroundings can change dramatically in just weeks or months.
As with most children, a picture of these youngsters taken today won't
look the same as one snapped a few months from now.
The movie shows jets of gas plowing into space at hundreds of thousands
of miles per hour and moving shadows billions of miles in size. The young
star systems reside about 450 light-years from Earth in the Taurus-Auriga
molecular cloud, one of the nearest stellar nurseries to our planet. Both
systems are probably less than a million years old, making them relative
newborns, given that stars typically live for billions of years. |
