NASA infrared imagery shows Hagupit nearing landfall in China

IMAGE: On Aug. 3 at 1:41 p.m. EDT (1741 UTC) NASA's Aqua satellite analyzed Typhoon Hagupit less than 2 hours before landfall in China. Using the Atmospheric Infrared Sounder or AIRS... view more  Credit: Credit: NASA JPL/Heidar Thrastarson NASA's Aqua satellite provided a look at Typhoon Hagupit as it was nearing landfall in southeastern China. One of the ways NASA researches tropical cyclones is using infrared…

VLBA finds planet orbiting small, cool star

Using the supersharp radio "vision" of the National Science Foundation's continent-wide Very Long Baseline Array (VLBA), astronomers have discovered a Saturn-sized planet closely orbiting a small, cool star 35 light-years from Earth. This is the first discovery of an extrasolar planet with a radio telescope using a technique that requires extremely precise measurements of a star's position in the sky, and only the second planet…

IMAGE: NASA's Aqua satellite passed over Isaias on Aug. 4 at 2:50 a.m. EDT (0650 UTC). Coldest cloud top temperatures (darker brown) were as cold as or colder than minus 70... view more  Credit: Credits: NASA/NRL Tropical Storm Isaias made landfall late on Aug. 3 and by today, Aug. 4, the huge storm stretched from Virginia to Maine. NASA satellites have been providing forecasters with rainfall…

Surprisingly dense exoplanet challenges planet formation theories

IMAGE: New detailed observations with NSF's NOIRLab facilities reveal a young exoplanet, orbiting a young star in the Hyades cluster, that is unusually dense for its size and age. Slightly smaller... view more  Credit: NOIRLab/NSF/AURA/J. Pollard New detailed observations with NSF's NOIRLab facilities reveal a young exoplanet, orbiting a young star in the Hyades cluster, that is unusually dense for its size and age. Weighing in…

New study: The quiet Sun is much more active than we...

IMAGE: The brightenings observed in the polar areas on the solar maps could be identified as coronal holes. view more  Credit: Aalto University Solar activity varies in 11-year cycles. As the activity cycle switches to a new one, the Sun is usually very calm for several years. For a long time, researchers have believed that there is not much of interest going on in the Sun…

Stars rich in phosphorus: Seeds of life in the universe

IMAGE: Scheme which represents the origin of phosphorus on Earth, with respect to possible stellar sources of phosphorus in our Galaxy view more  Credit: Gabriel Pérez Díaz, SMM (IAC) All the chemical elements in the universe, except for hydrogen and most of the helium, were produced inside stars. But among them there are a few (carbon, nitrogen, oxygen, sulphur and phosphorus) which are particularly interesting because…

Unequal neutron-star mergers create unique “bang” in simulations

IMAGE: Through a series of simulations, an international team of researchers has determined that some mergers of neutron stars produce radiation that should be detectible from Earth. When neutron stars of... view more  Credit: Adapted from figure 4 in "Accretion-induced prompt black hole formation in asymmetric neutron star mergers, dynamical ejecta and kilonova signals.

Washington, DC-- New work led by Carnegie's Peng Ni and Anat Shahar uncovers new details about our Solar System's oldest planetary objects, which broke apart in long-ago collisions to form iron-rich meteorites. Their findings reveal that the distinct chemical signatures of these meteorites…

NASA puts visible and water vapor eyes on Tropical Storm Isaias

IMAGE: NASA's Aqua satellite provided a visible image to forecasters of Tropical Storm Isaias of Florida's east coast on Aug. 2 at 1:30 p.m. EDT. view more  Credit: Image Courtesy: NASA Worldview, Earth Observing System Data and Information System (EOSDIS). NASA's Aqua satellite obtained visible and water vapor imagery as Tropical Storm Isaias continued moving along the east coast of Florida. On Aug. 3, Warnings and…
