Analog of the Milky Way and the Magellanic Clouds
A hunt for merging dwarf galaxies has yielded an intriguing result: 180 million light-years away, a galaxy very similar to the Milky Way — with two dwarf-galaxy satellites just like our own Magellanic clouds
Little Eyes on Large Solar Motions
What can we learn from observations made with digital cameras mounted on ~10-cm telescopes? It turns out, a lot about the solar corona.

Have you ever considered the idea of a cosmic velocity web? Learn more about these intriguing visualizations from the study led by Daniel Pomarède.
How Do Earth-Sized, Short-Period Planets Form?
Matching theory to observation often requires creative detective work. In a new study, scientists have used a clever test to reveal clues about the birth of speedy, Earth-sized planets.
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.
