New Efforts to Identify Dark Matter

Is dark matter “cold”, “warm”, or “hot”? New observations are helping us identify what makes up our universe.

red dwarf exoplanet

We’ve spent the last couple decades searching for planets around our nearest stellar neighbor, the red dwarf Proxima Centauri. Here’s a look at what we’ve learned so far.

simulations of Pop III star groups

Astrobites reports on simulations of the first groups of stars in our universe, which reveal how these groups evolve and where they might be hiding in the local universe.

Why Is Mercury So Far from the Sun?

Why is Mercury’s orbit so large, compared to the close-in orbits of the planets observed in many exoplanetary systems? Astrobites reports on a recent study seeking to answer this question.
