The astro-ph Reader’s Digest
Last month Nasa announced, in what seems like a roughly annual event, the discovery of “Earth 2.0″. Described as a “Bigger, Older Cousin to Earth”, Kepler 452b is the first small planet (defined here as less than twice the radius of the Earth) to be in a roughly one year orbit around a Sun-like star.
But is it otherwise that similar to the Earth? Is it potentially habitable? To try and answer that, let’s look at the discovery paper.
In today’s paper, the authors use Cepheid distance moduli to study the structure of the SMC.
We’re attempting to map the universe in fine detail at its largest scales in 3D. Meet the astrophysical rouges that seek to upend our goal, and the tools we need to weed them out.
Today’s astrobite is not about disc jockey insects informing us about spacetime. Read on to find out a novel way of detecting electromagnetic counterparts of merging supermassive black holes.
Failed supernovae result in massive stars disappearing into the night sky without a trace. Although many stars may meet this fat, we’re just beginning to look for them!
Solar neutrinos constrain the origin of the elements in the Big Bang.

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.
