Early on the morning of Dec. 19, 2013, the pre-dawn sky above the coastal town of Kourou in French Guiana was briefly sliced by the brilliant exhaust of a Soyuz VS06 rocket as it ferried ESA's "billion-star surveyor" Gaia into space, on its way to begin a five-year mission to map the precise locations of our galaxy's stars. From its position in orbit around L2 Gaia will ultimately catalog the positions of over a billion stars… and in the meantime it will also locate a surprising amount of Jupiter-sized exoplanets – an estimated 21,000 by the end of its primary mission in 2019.

The celestial critter in the new Hubble telescope photo is actually a cloud of gas stretching one light-year (10 trillion kilometers) across, scientists said. This cloud is in the process of collapsing under its own gravity to give birth to a star — but it's a race against time, because the established bright stars in its vicinity are fighting this process.
