The Q Continuum simulation is currently the largest cosmological simulation available, evolving (1300 Mpc)^3 and over half a trillion particles.
How Normal is Our Solar System?
To date, we’ve discovered nearly 2000 confirmed exoplanets, as well as thousands of additional candidates. Amidst this vast sea of solar systems, how special is our own?
Collapsing Enormous Stars
A recent study explores what we would see if supermassive stars in the early universe collapsed directly into black holes.
Bow Shock Leads the Way for a Speeding Hot Jupiter
A bow shock has been detected ahead of transiting exoplanet HD 189733b, providing a potential indicator of the remarkably strong magnetic field of the planet.
What X-Shaped Sources Tell Us About Gravitational Waves
A new study suggests we may be over-predicting the rate of galaxy mergers — and the gravitational wave background — by counting X-shaped radio sources.
What’s Causing the Activity on Comet 67P?
Recent models provide an explanation for the “early activity” unexpectedly emerging from the neck of comet 67P.
Forming Stars From the Cosmic Web
Observations of starbursts in low-metallicity galaxies have provided long-awaited evidence supporting predictions of how stars formed throughout cosmic history.
Water Vapor in an Unexpected Location
A recent study has found that the transitional disk DoAr 44 contains water vapor in its inner regions.
Explaining the Kuiper Belt with a Jumping Planet
Neptune’s unusual migration in the early years of our solar system might have created features we now observe in the Kuiper Belt.
Featured Image: A Supernova Remnant in X-Rays
Chandra X-ray images of RCW 103 provide an updated picture of what’s happening in this puzzling supernova remnant.
Don’t Cross the (Tidal) Streams
When an unfortunate star passes too close to a dormant supermassive black hole it gets torn apart by tidal forces, feeding the black hole for a short time. A recent study of the streams of stellar material in these events explains why we might be missing many of them.
