An artist's rendition of the 1-million-year-old star system UX Tau A, located approximately 450 light-years away. Observations from NASA's Sptizer Space Telescope showed a gap in the dusty disk swirling around the system's central star.

Astronomers have detected dust grains glomming together around a faraway star, capturing a snapshot of what appear to be newly forming alien planets caught in the act of being born.

Scientists used the Subaru Telescope in Hawaii to image the disk of dust and gas surrounding UX Tauri A, a young star found about 450 light-years from Earth in the constellation Taurus (The Bull). Analysis of the image revealed large and non-spherical dust particles — a telltale sign that grains are adhering to each other in a process that will eventually lead to planet formation, researchers said.

Ancient people probably assembled the massive sandstone horseshoe at Stonehenge more than 4,600 years ago, while the smaller bluestones were imported from Wales later, a new study suggests.

The conclusion, detailed in the December issue of the journal Antiquity, challenges earlier timelines that proposed the smaller stones were raised first.

"The sequence proposed for the site is really the wrong way around," said study co-author Timothy Darvill, an archaeologist at Bournemouth University in England. "The original idea that it starts small and gets bigger is wrong. It starts big and stays big. The new scheme puts the big stones at the center at the site as the first stage."
