Aluminum on the way to titanium strength

IMAGE: 3D-printed detail prototype. view more  Credit: © Sergey Gnuskov/NUST MISIS NUST MISIS scientists have proposed a technology that can double the strength of composites obtained by 3D printing from aluminum powder, and advance the characteristics of these products to the quality of titanium alloys: titanium's strength is about six times higher than that of aluminum, but the density of titanium is 1.7 times higher. The…

NASA investigated rainfall in Hurricane Michael as it was developing

The Global Precipitation Measurement mission or GPM core satellite analyzed rainfall and structure of an intensifying low pressure area in the western Caribbean Sea on Oct. 5. That system strengthened into what has become Category 2 Hurricane Michael on Oct. 9. On Friday, Oct. 5, the National Hurricane Center (NHC) indicated that the low pressure center in the western Caribbean Sea may become a tropical…

TRIUMF launches new Five-Year Plan 2020-2025

NASA sees the development of Eastern Atlantic Tropical Storm Nadine

As Hurricane Michael barrels toward the U.S. states along the northwestern Gulf of Mexico, and Tropical Storm Leslie lingers in the Central Atlantic, Tropical Storm Nadine has formed off the west coast of Africa in the far eastern Atlantic. NASA-NOAA's Suomi NPP satellite provided a visible image of the new named storm. On Oct. 9, the VIIRS instrument aboard NASA-NOAA's Suomi satellite provided a visible…

The threat of Centaurs for the Earth

The astrophysicists Mattia Galiazzo and Rudolf Dvorak from the University of Vienna, in collaboration with Elizabeth A. Silber (Brown University, USA) investigated the long-term path development of Centaurs (solar system minor bodies which originally have orbits between Jupiter and Neptune). These researchers have estimated the number of close encounters and impacts with the terrestrial planets after the so-called Late Heavy Bombardment (about 3.8 billion years…

NASA to Televise Two Spacewalks, Preview Briefing

Astronauts on the International Space Station will conduct spacewalks Friday, Oct. 19, and Thursday, Oct. 25, to continue power system upgrades, and experts will preview the work during a news conference Tuesday, Oct. 16, at NASA’s Johnson Space Center in Houston.

The cosmological lithium problem

The international collaboration n_TOF, in which a group of University of Seville researchers participated, has made use of the unique capacities of three of the world's nuclear facilities, such as PSI (Paul Scherrer Institute, Suiza), ISOLDE (ISotope On-Line DEvice, CERN) and n_TOF (neutron-Time Of Flight, CERN), to carry out a new experiment aimed at exploring an explanation of the Cosmological Lithium Problem based on a…

NASA looks at large Leslie lingering in Atlantic

IMAGE: At 1:40 a.m. EDT (0540 UTC) on Oct. 5, 2018 the MODIS instrument aboard NASA's Aqua satellite revealed strongest storms with the coldest cloud top temperatures (yellow) northwest of Leslie's... view more  Credit: NASA/NRL NASA's Aqua satellite passed over the Central Atlantic Ocean and obtained infrared data on Leslie, now weakened to a large tropical storm. The National Hurricane Center or NHC said that Leslie…

NASA investigates Tropical Storm Kong-Rey’s rainfall rates

IMAGE: The GPM or Global Precipitation Measurement mission core observatory satellite passed above Kong-Rey on Oct. 5. GPM indicated that rain was falling at over 1.8 inches (45.7 mm) per hour... view more  Credit: NASA/JAXA/NRL The Global Precipitation Measurement mission or GPM core satellite passed over Tropical Storm Kong-Rey and analyzed the rates in which rain was falling throughout the storm. At the time GPM passed…

W. M. Keck Observatory awarded NSF grant to develop next-generation adaptive...

IMAGE: Adaptive optics (AO) measures and then corrects the atmospheric turbulence using a deformable mirror that changes shape 1,000 times per second. Initially, AO relied on the light of a star... view more  Credit: W. M. Keck Observatory/Andrew Richard Hara Maunakea, Hawaii - Nearly two decades after pioneering the technology on large telescopes, W. M. Keck Observatory is once again pushing the boundaries in the field…
