Astronomers driving the Atacama Large Millimeter/submillimeter Array (ALMA) have imaged a cosmic "dinosaur egg;" a dense knot of star-birth within a pair of interacting galaxies, likely similar to ancient regions where star clusters were born.
07 May 2015, 07:47 AM ET
While some scientists are focused on finding Earth's exoplanet twin, one group is looking for twins of Venus. Their findings may help the hunt for Earth-like planets.
