NASA team to fly first-ever coronagraph to determine the formation of...

IMAGE: This image from the Solar and Heliospheric Observatory shows streaks of bright light. This represents material streaming out from the Sun, which is obscured in this picture by the central... view more  Credit: NASA/SOHO An observational technique first proposed more than four decades ago to measure the physical parameters of the corona that determine the formation of the solar wind -- the source of disturbances…

Simulating hypersonic flow transitions from smooth to turbulent

IMAGE: Deborah Levin, Professor of Aerospace Engineering, University of Illinois at Urbana-Champaign. view more  Credit: L. Brian Stauffer To break out of Earth's lower orbit, hypersonic vehicles must reach speeds greater than Mach 5. At these hypersonic speeds, the air particles and gases that flow around the vehicle and interact with the surfaces generate heat and create shock waves that disturb the flow's equilibrium. New research…

ALMA and MUSE detect galactic fountain

IMAGE: Composite image of the Abell 2597 galaxy cluster showing the fountain-like flow of gas powered by the supermassive black hole in the central galaxy. The yellow is ALMA data showing... view more  Credit: ALMA (ESO/NAOJ/NRAO), Tremblay et al.; NRAO/AUI/NSF, B. Saxton; NASA/Chandra; ESO/VLT Observations by ALMA and data from the MUSE spectrograph on ESO's VLT have revealed a colossal fountain of molecular gas powered by…

Galaxy-scale fountain seen in full glory

The yellow is ALMA data of... view more  Credit: ALMA (ESO/NAOJ/NRAO), Tremblay et al.; NRAO/AUI/NSF, B. Saxton; NASA/Chandra; ESO/VLT A billion light-years from Earth lies one of the universe's most massive structures, a giant elliptical galaxy surrounded by a sprawling cluster…

Satellite finds Tropical Cyclone 03S developing in Southern Indian Ocean

IMAGE: At 5:12 a.m. EDT (0912 UTC) on Nov.6, the VIIRS instrument aboard NOAA's NOAA-20 satellite captured a visible image of Tropical Cyclone 03S in the Southern Indian Ocean... view more  Credit: NASA/NRL Tropical Cyclone 03S formed in the Southern Indian Ocean and the NOAA-20 satellite passed overhead and captured a visible image of the storm. At 5:12 a.m. EDT (0912 UTC) on Nov.6, the Visible…

Cosmic fountain offers clues to how galaxies evolve

IMAGE: Artist impression of Abell 2597 showing the central supermassive black hole expelling cold, molecular gas -- like the pump of a giant intergalactic fountain. view more  Credit: NRAO/AUI/NSF; D. Berry Galaxy evolution can be chaotic and messy, but it seems that streams of cold gas spraying out from the region around supermassive black holes may act to calm the storm. This is according to an…

Ultra-hot gas around remnants of sun-like stars

IMAGE: This is an artist's impression of the hot white dwarf GALEXJ014636.8+323615 (white) and its ultra-hot circumstellar magnetosphere (purple) trapped with the magnetic field (green). view more  Credit: N. Reindl Solving a decades-old mystery, an international team of astronomers have discovered an extremely hot magnetosphere around a white dwarf, a remnant of a star like our Sun. The work was led by Dr Nicole Reindl, Research…

Weakening Tropical Storm Xavier observed by NASA

As Tropical Storm Xavier continued to rain on western Mexico, the Global Precipitation Measurement mission or GPM core satellite analyzed the rate in which rain was falling. The next day, Nov, 6, Xavier had weakened to a remnant low pressure area. The GPM core observatory satellite passed directly above tropical storm Xavier's low level center of circulation on November 4, 2018 at 11:33 a.m. EDT…

Laboratory experiments probe the formation of stars and planets

PORTLAND, Ore.--The cosmos is a void dotted with stars and an ever-increasing number of newly-observed planets beyond our solar system. Yet, how these stars and planets formed out of clouds of interstellar dust and gas remains mysterious. The study of black holes provides clues that could help solve this mystery. Black holes are typically depicted as vacuum cleaners sucking up all the nearby matter and…
