The papers are published in The Astrophysical Journal and the Monthly Notices of the Royal Astronomical Society and show that NASA's James…

Low-metallicity globular star cluster challenges formation models

On the outskirts of the nearby Andromeda Galaxy, researchers have unexpectedly discovered a globular cluster (GC) - a massive congregation of relic stars - with a very low abundance of chemical elements heavier than hydrogen and helium (known as its metallicity), according to a new study. The GC, designated RBC EXT8, has 800 times lower abundance of these elements than the Sun, below a previously-observed…

NASA finds wind shear affecting Tropical Storm Nangka post-landfall

IMAGE: On Oct. 14, 2020 at 2:25 a.m. EDT (0625 UTC), NASA's Aqua satellite provided a visible image of Tropical Storm Nangka after it made landfall in northeastern Vietnam.... view more  Credit: Credit: NASA/NRL Tropical Storm Nangka made landfall south of Haiphong, Vietnam and began to weaken. NASA's Aqua satellite revealed wind shear was affecting the storm as it continued to push inland. The Moderate Resolution…

A billion tiny pendulums could detect the universe’s missing mass

IMAGE: Dark matter, the hidden stuff of our universe, is notoriously difficult to detect. In search of direct evidence, NIST researchers have proposed using a 3D array of pendulums as force... view more  Credit: NIST Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have proposed a novel method for finding dark matter, the cosmos' mystery material that has eluded detection for…

NASA rainfall imagery reveals Norbert regains tropical storm status

IMAGE: On Oct. 14 at 4:30 a.m. EDT (0830 UTC), NASA's IMERG estimated Tropical Storm Norbert was generating as much as 30 mm(1.18 inches of rain [dark pink]) near the center... view more  Credit: Credit: NASA/NOAA/NRL Norbert has been meandering around in the Eastern Pacific Ocean for several days as a tropical depression. A NASA satellite rainfall product that incorporates data from satellites and observations revealed…

NASA Astronaut Kate Rubins, Crewmates Arrive Safely at Space Station

NASA astronaut Kate Rubins and two Russian cosmonauts arrived aboard the International Space Station on Oct. 14, returning a medical researcher to the orbiting laboratory ahead of the 20th anniversary of uninterrupted human presence in space.

Scientists develop detector for investigating the sun
