Astronomers Identify 157-Day Cycle in Ultra-Powerful Radio Bursts from Space There are a lot of things in the universe that we don’t fully understand, and Fast Radio Bursts (FRBs) are at the top of the list. We didn’t even know these phenomena even existed until 2007, and since then we’ve …

Archaeologists Use Ground-Penetrating Radar to Map Ancient Roman City of Falerii Novi The first high-resolution ground-penetrating radar survey of a complete ancient Roman town — Falerii Novi, in Lazio, Italy — has revealed previously unrecorded public buildings, such as a temple, a macellum or market building, a bath complex, and …

New Study Sheds Light on Diet of Juvenile Great White Sharks The diet of juvenile white sharks (Carcharodon carcharias) is about 32% mid-water fish, 17% bottom-dwelling fish, 5% reef fish, and 15% batoid fish such as stingrays; the remainder is unidentified fish or less abundant prey, according to new research …

Experiments with Tritium and Helium-3 Reveal New Questions in Understanding of Nuclear Structure Physicists from the Jefferson Lab Hall A Tritium Collaboration have compared the nuclei of helium and hydrogen isotopes to each other to get a clearer view of how the components of the nuclei are arranged and found …

Faster than Previously Thought Saturn is orbited by 82 moons, and tidal friction within the giant planet causes the moons to migrate outwards. In a study published this week in the journal Nature Astronomy, researchers used two independent measurements obtained with NASA’s Cassini spacecraft to measure Titan’s orbital expansion rate. …

Mars Odyssey Captures New Thermal Images of Phobos Astronomers using the Thermal Emission Imaging System (THEMIS) camera on NASA’s Mars Odyssey orbiter have captured new infrared images of Phobos, the larger and inner of the two natural Martian satellites. These images from the THEMIS camera on NASA’s Mars Odyssey orbiter …

Scientists Find a ‘Mirror Image’ of Our Solar System While scanning the skies, humanity has identified thousands of exoplanets orbiting distant stars. However, very few of them are at all similar to Earth. Now, the Max Planck Institute for Solar System Research in Göttingen reports a newly discovered exoplanet could …

The InSight Mars Lander’s Heat Probe Finally Makes It Underground NASA’s InSight lander touched down at Elysium Planitia on Mars in late 2018, and it has subsequently made history by taking the first seismic readings on another planet. However, the mission’s burrowing probe was stuck on the surface after the …

People with Severe Vision Loss Less Accurately Judge Distance of Nearby Sounds, Study Shows A new study shows that greater severity of vision loss is associated with increased auditory judgments of distance and room size; on average, participants with severe visual losses perceived sounds to be twice as far away, …
