Low-mass stars are much more common than massive ones. But massive stars outshine the smaller ones a thousand to one! How can astronomers account for this hidden majority? Maybe alcohol will help…
Amino acids were possibly brought to Earth by meteorite impacts, which contaminated the young environment with organic compounds. However, where and how did these most basic ingredients of life form in the first place?
If parallel Universes exist, their fundamental laws of physics may be different to ours. How sensitive is the existence of life to these laws? Read on to find out.
The process of star formation is exciting. During the early phases, a protostar undergoes two characteristic collapses. Today’s Astrobite explains the two collapse phases and briefly discusses their effects on the “final” product: the second core.
Planets in binary star systems can receive a sizable amount of water from asteroids getting perturbed out of their orbits
How do galaxies and black holes co-evolve and grow together? The authors of this paper search for a link between active black holes with high and low amounts of radio emission and search for a connection to mergers of galaxies which can grow both the mass of galaxies and black holes simultaneously.

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?
