ALMA sees super stellar nurseries at heart of starburst galaxy

16 February 2015 Astronomy Now

Starburst galaxies transmute gas into new stars up to 1,000 times faster than typical spiral galaxies like the Milky Way. To try and understand why, an international team of astronomers used the Atacama Large Millimeter/submillimetre Array (ALMA) to dissect a cluster of star-forming clouds at the heart of NGC 253 — one of the nearest starburst galaxies.

Astronomers catch multiple-star system in first stages of formation

11 February 2015 Astronomy Now

Scientists studying a dense core of gas called Barnard 5 that lies 800 light-years away in the constellation Perseus discover a young protostar and three dense condensations that will give birth to four stars in ~40,000 years.

Swarms of Pluto-size objects kick up dust around adolescent Sun-like star

14 December 2014 Astronomy Now

ALMA observations of the dusty protoplanetary disc surrounding a star known as HD 107146 provides evidence for an entire family of orbiting Pluto-size objects, a solar system in transition from early life to maturity where planets have finished forming.

Planet-forming disc around young star revealed in unprecedented detail

6 November 2014 Astronomy Now

A new image from ALMA, the Atacama Large Millimeter/submillimeter Array, reveals extraordinarily fine detail that has never been seen before in the planet-forming disc around a young star.
