The newly discovered exoplanet Kepler-78b has a size, mass, and density similar to Earth. This is the smallest exoplanet to have a measurement of both its radius and its mass.
Constraining fine-structure constant variations using QSOs
From measurements of quasar spectra, we can determine whether or not the fine structure constant is really a constant.
Galactic Archaeology through Stars
How the various structures within our own Milky Way galaxy evolved is still an open question that astronomers have been slowly piecing together for a very long time. These galactic archaeologists are beginning to test a previously proposed method known as “chemical tagging” to fingerprint stars in our galaxy and trace their origin.
The Changing Faces of Active Galactic Nuclei
Has a multi-wavelength study of AGN across a large redshift range revealed that these energetic giants do not impact upon their host galaxy as significantly as previously thought?
