NOAA's JPSS-1 satellite provided a visible image of the tropical storm after it made landfall along the Pilbara Coast in the northwestern part of Western Australia.
The paper, titled "Collocated ionosonde and dense GPS/GLONASS network measurements of midlatitude MSTIDs", covers the first ever complex analysis of MSTIDs obtained by two methods of radio sounding. MSTIDs, which are huge wave perturbations somewhat resembling aurora borealis, are invisible in midlatitude areas.
Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets blasting radio waves. By analyzing nearly 8000 quasars from the Sloan Digital Sky Survey, research team found that the oxygen emissions are 1.5 times stronger in radio loud quasars than in radio quiet quasars. This implies that spin is an important factor in the generation of jets.
Increased fluctuations in the path of the North Atlantic jet stream since the 1960s coincide with more extreme weather events in Europe such as heat waves, wildfires and flooding. The new research published in Nature Communications is the first reconstruction of historical changes in the North Atlantic jet stream prior to the 20th century. By using tree rings, the researchers developed a historical look at the position of the North Atlantic jet back to 1725.
Astronomers using NASA's Hubble Space Telescope have uncovered the largest known population of brown dwarfs sprinkled among newborn stars in the Orion Nebula.
A new NASA study shows rings, arcs and spirals in disks around stars may not be caused by planets. They may self-generate.
Tropical Cyclone Joyce, formerly known as tropical cyclone 5S, was moving south along the coast of Cape Leveque, Western Australia on Jan. 11 when a polar-orbiting satellite passed overhead. NOAA's JPSS-1 satellite provided a visible image of the tropical storm as it continued to move south along the northwestern part of Western Australia.
By seeing which way the wind blows, a University of Texas at Dallas fluid dynamics expert has helped propose a solution to a Martian mountain mystery. Dr. William Anderson, an assistant professor of mechanical engineering, co-authored a paper published in the journal Physical Review E that explains the common Martian phenomenon of a mountain positioned downwind from the center of an ancient meteorite impact zone.
Astronomers using the Green Bank Telescope have made the first definitive interstellar detection of benzonitrile, an intriguing organic molecule that helps to chemically link simple carbon-based molecules and truly massive ones known as polycyclic aromatic hydrocarbons. This discovery is a vital clue in a 30-year-old mystery: identifying the source of a faint infrared glow that permeates the Milky Way and other galaxies.
Scientists studying a cold molecular cloud of the Taurus region with radio telescopes have detected the presence of a particular organic molecule called benzonitrile. The finding marks the first time a specific aromatic molecule has been identified in space using radio spectroscopy.
