Webb Looks at Massive Star-Forming Complex in Large Magellanic Cloud
Using the Mid-InfraRed Instrument (MIRI) onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have captured a spectacular image of N79, a region of interstellar ionized hydrogen in the Large Magellanic Cloud. This Hubble image shows N79, a star-forming region located 163,000 light-years away in the constellation of Dorado. Image credit: NASA / ESA / CSA
New Observations of Messier 87’s Black Hole Support Einstein’s Theory of General Relativity
In April 2019, the Event Horizon Telescope (EHT) Collaboration reported the first-ever event-horizon-scale images of a black hole, resolving the central black hole — known as M87* — in the giant elliptical galaxy Messier 87 (M 87). In a new paper, astronomers present new images of M87* from data collected by the Atacama Large Millimeter/submillimeter
Megalodon May Have Been More Slender than Previously Thought
The megatooth shark, Otodus megalodon, which likely reached at least 15 m in total length, is an iconic extinct shark represented primarily by its gigantic teeth in the Neogene fossil record. This ancient species is largely known only from its teeth and vertebrae in the fossil record. Thus, the living great white shark (Carcharodon carcharias)
Archaeologists Discover 2,500-Year-Old System of Urban Centers in Amazonian Ecuador
When intact, the Amazonian forest is dense and difficult to penetrate, both on foot and with scanning technologies. Over the past several years, however, improved light detection and ranging scans have begun to penetrate the forest canopy, revealing previously unknown evidence of past Amazonian cultures. In a new paper, CNSR archaeologist Stéphen Rostain and his
Mars Express Finds New Evidence for Ice-Rich Layered Deposits in Medusae Fossae
Over 15 years ago, ESA’s Mars Express spacecraft studied the Medusae Fossae Formation, revealing enigmatic deposits up to 2.5 km deep. From those early observations, it was unclear what the deposits were made of, but the new research has an answer. This image shows a height map of the Martian surface, with lowest land in
