Tropical Cyclone Son-Tinh makes landfall and NASA examines its trail of...

Tropical Cyclone Son-Tinh made landfall in Vietnam and left a trail of heavy rainfall in its wake. NASA's Global Precipitation Measurement mission or GPM core satellite provided an estimate of that soggy trail through the Gulf of Tonkin. Tropical storm Son-Tinh struck Hainan Island, China and was headed toward northern Vietnam when the GPM core observatory satellite passed over the Gulf of Tonkin, South China…

Traveling to the sun: Why won’t Parker Solar Probe melt?

This summer, NASA's Parker Solar Probe will launch to travel closer to the Sun, deeper into the solar atmosphere, than any mission before it. If Earth was at one end of a yard-stick and the Sun on the other, Parker Solar Probe will make it to within four inches of the solar surface. Inside that part of the solar atmosphere, a region known as the…

Discovering structure in the outer corona

In 1610, Galileo redesigned the telescope and discovered Jupiter's four largest moons. Nearly 400 years later, NASA's Hubble Space Telescope used its powerful optics to look deep into space -- enabling scientists to pin down the age of the universe. Suffice it to say that getting a better look at things produces major scientific advances. In a paper published on July 18 in The Astrophysical…

CALET succeeds in direct measurements of cosmic-ray electron spectrum up to...

IMAGE: Approximately doubled statistics above 500GeV by using full acceptance of CALET. view more  Credit: Waseda University An international team of researchers succeeded in extending their result from a previous study and directly measured the cosmic-ray all-electron (electron + positron) spectrum in an energy range from 11 GeV to 4.8 TeV with the Calorimetric Electron Telescope (CALET). CALET, a detector optimized to observe high-energy electrons, was…

Suomi NPP satellite finds an elongated Tropical Storm Ampil

IMAGE: On July 19, NASA-NOAA's Suomi NPP satellite captured an infrared image of newly formed Tropical Storm Ampil in the Philippine Sea. Red and yellow colors indicate coldest temperatures and strongest... view more  Credit: NASA/NOAA/NRL Tropical Depression 12W formed in the Philippine Sea and NASA-NOAA's Suomi NPP satellite analyzed the storm in infrared light. The depression strengthened into Tropical Storm Ampil later on July 18. On…

SD mines scientists and students contribute to IceCube breakthrough

RAPID CITY, SD (July 17, 2018) - An international team of scientists, including researchers at the South Dakota School of Mines & Technology, have found the first evidence of a source of high-energy cosmic neutrinos, ghostly subatomic particles that can travel unhindered for billions of light years from the most extreme environments in the universe to Earth. Detecting high-energy cosmic neutrinos requires a massive particle…

Billion-year-old lake deposit yields clues to Earth’s ancient biosphere

A sample of ancient oxygen, teased out of a 1.4 billion-year-old evaporative lake deposit in Ontario, provides fresh evidence of what the Earth's atmosphere and biosphere were like during the interval leading up to the emergence of animal life. The findings, published in the journal Nature, represent the oldest measurement of atmospheric oxygen isotopes by nearly a billion years. The results support previous research suggesting…

SwRI-led team creates high-fidelity images of Sun’s atmosphere

SAN ANTONIO -- July 18, 2018 -- A Southwest Research Institute-led team discovered never-before-detected, fine-grained structures in the Sun's outer atmosphere, or corona. The team imaged this critical region in detail using sophisticated software techniques and longer exposures from the COR-2 camera on board NASA's Solar and Terrestrial Relations Observatory-A (STEREO-A). The Sun's outer corona is the source of the solar wind, the stream of…

Suomi NPP satellite sees compact storm Son-Tinh Headed for Vietnam

IMAGE: On July 19, NASA-NOAA's Suomi NPP satellite captured a visible image of Tropical Storm Son-Tinh in the Gulf of Tonkin. The image showed a compact system with a small area... view more  Credit: Credits: NASA/NOAA/NRL NASA-NOAA's Suomi NPP satellite flew over Tropical Storm Son-Tinh on July 18 after it crossed over Hainan Island, China and as it moved into the Gulf of Tonkin. The Visible…

Planck: final data from the mission lends support to the standard...

In 2013, ESA's Planck mission unveiled a new image of the cosmos: an all-sky survey of the microwave radiation produced at the beginning of the Universe. This first light emitted by the Universe provides a wealth of information about its content, its rate of expansion, and the primordial fluctuations in density that were the precursors of the galaxies. The Planck consortium publishes the full and…
