Worlds next door: looking for habitable planets around Alpha Centauri

Could life survive around the nearest stars? In collaboration with the Breakthrough Initiative, Saber Astronautics and NASA’s Jet Propulsion Laboratory, Professor Peter Tuthill is leading TOLIMAN, a project to discover if the nearest stars have planets that could support life. A mission to discover new planets potentially capable of sustaining life around Earth’s nearest neighbour, …

A FLASH combination: ASKAP and MUSE sniff out gas around galaxies

The timescales in which star-forming galaxies deplete their gas is found to be short relative to the age of the Universe. This points to the conclusion that galaxies must have a way to replenish their gas reservoirs and indeed, early cosmological simulations reveal cold gas being channeled along dark matter filaments. At the same time, …

Galactic Archaeology and Modeling the Milky Way

Researchers have created a model of the evolution of the Milky Way which explains how key chemical distributions in the galaxy’s stars came to be. One of the biggest questions in astronomy is related to how our home galaxy, the Milky Way, came to be in its current state. Whilst this might seem like it …

Remnants of an old neighbour engulfed by the Milky Way

The paper, lead by Zhen Wan from USyd and co-authored by ASTRO 3D researchers and affiliates Jeffrey Simpson, Sarah Martell, Sanjib Sharma and Gayandhi De Silva, provides a new perspective about how galaxies evolve.  The research looks at a star cluster that is in the process of being pulled into the Milky Way, and may very well be the last of its kind. What …
