The Sun is a bit over 4.5 billion years old, leading many to think of all stars as billions of years in age. Astronomers have now demonstrated that isn't always the case. Using high-resolution millimeter and submillimeter imaging telescope arrays, John Tobin of the National Radio Astronomy Observatory (NRAO) and his collaborators have now discovered an infant star whose age is measured in thousands, rather than billions, of years. While at present the protostar has only about a fifth of the Sun's mass, projections point to the eventual formation of a stellar system broadly similar to our Sun and its planets.
