The third Extreme Solar System conference was held between Nov 29 to Dec 4th, in Kona, Hawaii, on the 20th anniversary of the first exoplanet detection around a main sequence star. This astrobite gives a brief overview of the conference.
Today we review a study searching for a way to measure the ages of stars in a galaxy. The quantity of long period variable stars gives information about the life cycle of a galaxy, and the authors explain that with their new technique it is possible to take the “pulse” of a galaxy.
What makes up the innards of the brightest galaxy in the universe?
Today we use a new paper to revisit the possible dwarf galaxy discovered 90 kpc from the Milky Way.
Planets with radii between Earth and Neptune and small radii are the most common in planetary systems. These planets are challenging to explain with classical models of planets. Do planets form instead in-situ in an inside-out manner?
These hot galaxies show signs of AGN and starburst activity occurring within their dusty interiors.
