Hubble peeks at stellar treats Looking its best ever is the star cluster NGC 2203, here imaged by the NASA/ESA Hubble Space Telescope. Aside from its dazzling good looks, this cluster of stars contains lots of astronomical treats that have helped astronomers puzzle together the lifetimes of stars. phys.org Go to SourceRead More →
Differences between discs of active and non-active galaxies detected for the first time A study led by researchers at the Instituto de Astrofísica de Canarias (IAC) comparing the discs of several pairs of spiral galaxies, active and non-active, concludes that in the active discs, the rotational motion of the stars is of greater importance. phys.org Go to SourceRead More →
Machine learning finds a surprising early galaxy New results achieved by combining big data captured by the Subaru Telescope and the power of machine learning have discovered a galaxy with an extremely low 1.6% oxygen abundance, breaking the previous record of the lowest abundance. The measured oxygen abundance suggests that most of the stars in this galaxy formed very recently. phys.org Go to SourceRead More →
Juno Captures Pictures of Ganymede for the First Time On July 5, 2016, NASA’s Juno spacecraft arrived around Jupiter, becoming the second mission in history to study the gas giant from orbit – the last being the Galileo spacecraft, which orbited Jupiter from 1995 to 2003. Since then, the spacecraft has gathered data on Jupiter’s atmosphere, composition, gravity field, and magnetic field in the … Continue reading “Juno Captures Pictures of Ganymede for the First Time” The post Juno Captures Pictures of Ganymede for the First Time appeared first on Universe Today.
