Advanced observational tools such as ALMA allow the detection of complex organic molecules – the building blocks of life. However, how and where they are formed is still unknown.
Cosmic reionization is a period in the Universe history when it switched from being predominantly neutral to mostly ionized. We still haven’t quite pinned down the source(s) that caused this transition, but we have our suspicions. It could be quasars. It could be galaxies. Or could it be something else?

How efficiently can a galaxy turn gas into stars? Most galaxies do so at a very typical rate, but some convert gas incredibly fast in a huge starburst – but how efficient can they get?
White dwarfs in a binary often merge into a variety of interesting phenomena. However, nobody has sought to understand the role that magnetic fields play during the merger. The authors simulate the merging of two white dwarfs with magnetic fields to see what happens.
The evolution of a galaxy is strongly dependent upon the environment the galaxy lives in. Galaxies moving through galaxy groups and galaxy clusters can get stripped of their gas that would otherwise be used to form stars. Today’s astrobite discusses simulations of the stripping and removal of the hot, gaseous coronae that surround galaxies.
The exoplanet hunt is on. The stakes are high. What will our next-generation telescopes find?

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?

The years of 2014 and 2015 may well be known as the time when our exploration of the solar system truly took off, as we explored asteroids, comets, and minor planets. Here’s a look back at what we’ve accomplished in the last year, and what we’re about to achieve in the year to come.
