Mysterious Gas Clouds between M31 and M33
Seven gas clouds have been found in the region between two galaxies. Are they part of a intergalactic filament or remnants from a past galaxy interaction?
Evidence for two distinct populations of Type Ia Supernovae
Type Ia Supernovae are extensively used in astronomy research, but the progenitors of these massive explosions are still not well understood. This paper discusses new evidence that there are two distinct populations of type Ia supernovae, and that they originate from different stellar populations.
Asteroid Excavation: Probing the interior of Vesta through major impacts
The asteroid Vesta has been scared by two giant impacts, dredging up material from deep below its surface. New simulations of the impacts allow us to trace where the material should end up and creates a conflict between theory and observation.
Asteroid belt found in the Vega System
A new asteroid belt discovered around Vega makes this system look more similar to the Solar System than we had previous thought. The gap between the two belts around Vega may indicate the presence of multiple planets.
