Monster Two-Lobed Radio Jet Detected in Early Universe
The newly-discovered radio jet spans an astonishing 215,000 light-years, and is associated with J1601+3102, an extremely radio-loud quasar that existed just 1.2 billion years after the Big Bang. This structure, observed by the Low Frequency Array (LOFAR), the Gemini Near-Infrared Spectrograph (GNIRS) on the Gemini North telescope, and the Hobby Eberly Telescope, is the largest
Earliest-Known Waterfowl Lived in Antarctica 69 Million Years Ago
Paleontologists from the United States and Australia have discovered and described a new, nearly complete skull of Vegavis iaai, a foot-propelled diver bird species that lived in Antarctica during the latest Cretaceous, between 69.2 and 68.4 million years ago. The new fossil provides insight into the bird’s feeding ecology and exhibits morphologies that support placement among
Ancient DNA Study Sheds New Light on History of Indo-European Languages
Paleoanthropologists from the University of Vienna and Harvard University have analyzed ancient DNA from 435 individuals from Eurasian archaeological sites dating between 6400-2000 BCE. They’ve discovered a previously unknown group, called Caucasus-Lower Volga (CLV) people, and found out that this population can be connected to all Indo-European-speaking populations. The Caucasus-Lower Volga group lived 4500-3500 BCE
Gaia Discovers Massive Exoplanet and Brown Dwarf around Nearby Low-Mass Stars
Astronomers using ESA’s Gaia star-mapping satellite have discovered two substellar companions — named Gaia-4b and Gaia-5b — orbiting two low-mass stars. An artist’s impression of the super-Jupiter exoplanet Gaia-4b. Image credit: ESA / Gaia / DPAC / M. Marcussen. Gaia-4b is a ‘super-Jupiter’ exoplanet (11.8 Jupiter masses) orbiting an M- or K-type dwarf star called
Impact-Generated Marsquakes Can Reach Deeper into Red Planet than Previously Known
In a new study, planetary researchers used global and high-resolution orbital imaging to discover a fresh, 21.5-m (71-foot) impact crater that appeared at the same time as one of the marsquakes detected by NASA’s InSight lander; this means the seismometer detected a meteoroid strike rather than geological activity within the planet. In an associated study
