A Cepheid Anomaly
Today we take a closer look at rare system that might just be host to an even rarer Cepheid.
The Small Magellanic Cloud in 3D
In today’s paper, the authors use Cepheid distance moduli to study the structure of the SMC.
Mapping the Milky Way
How many spiral arms does the Milky Way have? You might be surprised to learn that astronomers are still not completely sure.
A long-awaited discovery
More than 50 years ago, a Norwegian astronomer named Sjur Refsdal outlined an interesting new method for calculating the Hubble constant. Last November, astronomers found the perfect test case.
Discovering the mysterious companions of Cepheids
Cepheids are bright enough that we can use them to measure distances to other galaxies, but their luminosities also makes detecting their companions particularly difficult. So how do astronomers find their uncover their secret partners? Today’s paper takes a look…
A new tool for hunting exoplanetary rings
Planetary rings such as those around Saturn are fascinating features. Recent observations also reveal evidence for rings around exoplanets, but it’s a difficult task to distinguish these planets from ringless planets. This Astrobite presents a technique, which simplifies the search for candidates. Even better, the developed code is publicly available and allows you going out to look for candidates for exoplanetary rings.
