Although magnetic fields exist virtually everywhere, we still do not know quite a lot about the role they play in the evolution of our Universe. On galaxy scales and larger, they can be difficult to observe, but may play a crucial role in how they evolve. Today’s astrobite discusses work done to try and understand how initially weak fields in the early Universe can affect galaxy evolution over time.
On using photometric data from Kepler to study starspots, and to measure differential rotation rates.
Today we take a closer look at rare system that might just be host to an even rarer Cepheid.
The dark matter halos of galaxies and clusters of galaxies—objects of literally astrophysical dimensions—have lots to say about the mysterious, likely subatomic, dark matter particle.
Finding extraterrestrial intelligence would be one of the most enlightening and profound discoveries in history. Today’s post looks at two potential means of finding extraterrestrials by seeing their advanced technology elsewhere in the Milky Way and the Universe.
Astronomers have known for a while that GRBs are sign-posts to galaxies which are forming lots of stars. But today’s paper used radio observations of the gas to connect that star formation to a recent merger.

Planets seem to occur all over the place in the universe. However, it is still unknown how they form. The growth of objects larger than meter size is difficult because objects of this size quickly fall into the central star. This Astrobite gives a small overview of the meter-size barrier as found by Stuart J. Weidenschilling in 1977.
Much of what we know today about exoplanets is due to the success of the radial velocity method. Where does it stand now? What is its future?
