Today we take a look back to 1916, when distances were measured in light years and uncertainties weren’t to be included in publications. The nearly 100-year old discovery of a small star has large implications for our understanding of stellar astrophysics, even today.
Could the strange-looking irregular galaxies actually be remnants of the birth of galaxies? This paper demonstrates a method to find such galaxies.
Supernovae happen in the Milky Way at a rate of two or three per century. But, will we be able to see it when it happens next, or will dusty galactic center prevent us from studying it?
The IceCube project at the South Pole makes the first detection of high-energy extraterrestrial neutrinos.
In search of a good origin story for the building blocks of life, the authors of this paper have set their sights higher. Literally higher, to exoplanets’ skies.
In today’s paper, the authors study how the periods of two black hole x-ray binaries are changing. They find that the periods are decaying faster than expected based on standard theoretical arguments.
