Are millisecond pulsars causing excess gamma-rays?
Millisecond pulsars may be responsible for the extra gamma rays near the Galactic Center. Why haven’t we detected more of them?
Effects on Habitability from Nearby Neighboring Planets
Planets can live very close to one another, but are planetary neighbors destructive to life, or might they help it get started in the first place?
Disentangling Dark Matter Physics
We can’t study dark matter directly by our usual means of studying the cosmos: light. But dark matter leaves its fingerprints on the universe in other ways…
My cousin is out finding exoplanets, and what do I get? Stellar activity
In 2014, astronomers found evidence for the existence of two super-Earths orbiting the 10 billion years-old Kapteyn’s star. However, today’s paper is casting doubt on the detection of at least one of these planets, and stellar activity is to blame.
Observational Evidence for the First Generation of Stars
Have we found evidence for the first generation of stars? This paper details observations made of CR7, one of the brightest observed high redshift galaxies
The ‘Ultimate’ X-ray Sky Survey: Finding Active Galaxies in Superclusters
The XXL Survey is here as the rightful successor to the XMM-Newton survey that gave us a unique and extravagant look into the high-energy universe. Here, we look at some of the observations that the XXL has to offer!
