To unlock the secrets of the (local) universe, Adam Riess observes the brightness of supernovae and Cepheid variables to measure the distance to galaxies far, far away. Read more about his research before his plenary talk at #AAS231 on Tuesday.
Over its lifetime, the Milky Way has battled with several dwarf galaxies and won, leaving behind the streams of stars we observe today. This bite explores whether such a battle resulted in the formation of the mighty Monoceros ring!
In our latest installment of “how on Earth do we get to Proxima b?”, we consider the effects of magnetic fields on the trajectory of Breakthrough Starshot’s proposed sailcraft.
Here on Earth, and within the solar system, we have become very familiar with star-planet interactions through observations of the dazzling aurora. However we have not been able to observe it on an exoplanet before. Is it too dim? Or are we just limited by instrumentation?
With the imminent launch of the James Webb Space Telescope next year, many scientists are asking what is next? Today’s bite, which focuses on a recent workshop on global coordination: future space-based Ultraviolet-Optical-Infrared Telescopes, hopefully represents the first steps towards the next big space telescope.
