Researchers have identified a young star, located almost 11,000 light-years away, which could help us understand how the most massive stars in the universe are formed. This star, already more than 30 times the mass of our Sun, is still in the process of gathering material from its parent molecular cloud, and may be even more massive when it finally reaches adulthood.

The Very Large Telescope Interferometer at ESO’s Paranal Observatory in Chile has obtained the sharpest view ever of the dusty disc around an ageing star. For the first time such features can be compared to those around young stars — and they look surprisingly similar. It is even possible that a disc appearing at the end of a star’s life might also create a second generation of planets.

Mystery of missing exoplanet water solved using NASA space telescopes

14 December 2015 Astronomy Now

A survey of ten hot, Jupiter-sized exoplanets conducted with NASA’s Hubble and Spitzer telescopes has led a UK-US team to solve a long-standing mystery — why some of these worlds seem to have less water than expected. The findings offer new insights into the wide range of planetary atmospheres in our galaxy and how planets are assembled.
