Astronomers Stress the Need for Characterizing the Population of Nearby Potential Earth-Impactors

by Dan Majaess October 14, 2013

The meteor explosion over Russia in February 2013 raised concerns that even small asteroid impactors may wreak some havoc given our heavily populated cities.  A new study by NASA scientists aims to improve our understanding of such asteroids that are lurking in Earth’s vicinity.  The team, led by Amy Mainzer, noted that only a mere […]

Astronomers Refine Distances to our Closest Spiral-Galaxy Neighbors

by Dan Majaess June 10, 2013

M31 and M33 are two of the nearest spiral galaxies, and can form the basis for determining distances to more remote spiral galaxies and constraining the expansion rate of the Universe (the Hubble constant).  Hence the relevance and importance of several new studies that employed near-infrared data to establish solid distances for M31 (Andromeda) and M33 (Triangulum) (e.g., Gieren et […]
