Globular Clusters for Faint Galaxies
The origin of ultra-diffuse galaxies (UDGs) has posed a long-standing mystery for astronomers. New observations of several of these faint giants with the Hubble Space Telescope are now lending support to one theory.
Discovery of a Free-Floating Double Planet?
An object previously identified as a free-floating, large Jupiter analog turns out to be two objects — each with the mass of a few Jupiters. This system is the lowest-mass binary we’ve ever discovered.
Exploring the Minispiral at the Milky Way’s Center
The region around Sgr A*, the 4-million-solar-mass black hole at the heart of our galaxy, is a complex and dynamic place. New Atacama Large Millimeter/submillimeter Array (ALMA) observations of the Milky Way’s center now reveal more about this harsh, inhospitable environment.
A Partly Cloudy Exoplanet
Direct imaging of exoplanets was once only possible for the brightest of planets orbiting the dimmest of stars — but new observations of the Jupiter-like exoplanet 51 Eridani b provide tantalizing clues about its atmosphere.
ASKAP Joins the Hunt for Mysterious Bursts
ASKAP, the Australian Square Kilometre Array Pathfinder has only had a 3.4-day pilot survey and has already found a fast radio burst!
