New Efforts to Identify Dark Matter
Is dark matter “cold”, “warm”, or “hot”? New observations are helping us identify what makes up our universe.
The (Historical) Search for Planets Orbiting Proxima Centauri
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.
What Did the First Collections of Stars Look Like?
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.
When Charged Black Holes Merge
New research shows that mergers of charged black holes could generate a variety of observable signatures, from fast radio bursts to gamma-ray bursts.
A High-Velocity Collision With Our Galaxy’s Disk
A new study finds evidence that a high-velocity cloud may have smashed into the Milky Way’s disk five million years ago.
History of a Rare Radio Galaxy Revealed by Its Jets
The unusual structure of a recently discovered radio galaxy gives scientists clues about its temperamental past.
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.
Models of a Circumbinary Disk
This image captures a scene from a simulation of a binary star system surrounded by a circumbinary disk.
A New Player in the Search for Extraterrestrial Intelligence
Can we find life beyond Earth? A new experiment in the Search for ExtraTerrestrial Intelligence (SETI) has been conducted at the Murchison Widefield Array in Australia.
Exploring the Birth of Binary Stars
More than half of all stars are thought to be in binary or multiple star systems. But how do these systems form? The misaligned spins of some binary protostars might provide a clue.
Investigating Local Galaxies to Learn about Distant Ones
Astrobites reports on a study of nearby galaxies that mimic the properties of those found in the distant universe.
