In the search for extraterrestrial life, scientists have turned over all sorts of rocks. Mars, for example, has geological features that suggest it once had…
The discovery of an exoplanet has most often resulted from the monitoring of a star’s flicker (the transiting method) or its wobble (the radial velocity…
The slow fade of radioactive elements following a supernova allows astrophysicists to study them at length. But the universe is packed full of flash-in-the-pan transient…
Galaxies and dark matter go together like peanut butter and jelly. You typically don’t find one without the other. Therefore, researchers were surprised when they…
