On Sept. 9, 2018, NASA's Solar Dynamics Observatory, SDO, saw two lunar transits as the Moon passed in front of the Sun. A transit happens when a celestial body passes between a larger body and an observer. This first lunar transit lasted one hour, from 4:30 pm to 5:30 p.m. EDT and obscured 92 percent of the Sun at the peak of its journey. The second transit happened several hours later at 9:52 p.m. and lasted a total of 49 minutes, ending at 10:41 p.m. EDT. This transit only obscured 34 percent of the Sun at its peak.
Astronomers from the Department of Physics at the University of Tokyo discovered a dense disk of material around a young star, which may be a precursor to a planetary system. Their research could vastly improve models of how solar systems form, which would tell us more about our own place in the cosmos.
The conditions for life surviving on planets entirely covered in water are more fluid than previously thought, opening up the possibility that water worlds could be habitable, according to a new paper from the University of Chicago and Pennsylvania State University.
For centuries, scientists have worked to understand the makeup of Jupiter. It's no wonder: this mysterious planet is the biggest one in our solar system by far, and chemically, the closest relative to the Sun. Understanding Jupiter is a key to learning more about how our solar system formed, and even about how other solar systems develop.
But one critical question has bedeviled astronomers for generations: Is there water deep in Jupiter's atmosphere, and if so, how much?
A team of scientists led by researchers from the University of Hawai'i at Mānoa School of Ocean and Earth Science and Technology (SOEST) found the first direct evidence for the surface exposed water ice in permanently shaded regions (PSRs) of the Moon.
Heavy rainfall and towering cloud heights were the findings when Hurricane Lane was scanned by the Global Precipitation Measurement mission or GPM core observatory satellite on Aug. 17. Lane strengthened to a Category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale.
Tropical Storm Bebinca showed powerful, heavy rain-making thunderstorms on infrared satellite imagery when NASA's Terra satellite saw the storm along the northern Vietnam coast.
The Vietnam Hydrological Administration (VHA) has issued a tropical storm warning for coastal Vietnam.
Infrared light provides valuable temperature data to forecasters and cloud top temperatures give clues about highest, coldest, strongest storms within a tropical cyclone.
Astronomers have identified some of the earliest galaxies in the Universe.
The team from the Institute for Computational Cosmology at Durham University and the Harvard-Smithsonian Center for Astrophysics, has found evidence that the faintest satellite galaxies orbiting our own Milky Way galaxy are amongst the very first galaxies that formed in our Universe.
WASHINGTON - The U.S. Naval Research Laboratory's unique expertise in sun-viewing telescopes will be an integral part of the historic NASA Parker Solar Probe mission scheduled to launch Aug. 11 to better understand how the Sun affects our solar system.
The mission to "touch the Sun" is 60 years in the making and will bring a spacecraft carrying a suite of instruments the closest ever before to the Sun with NRL's Space Science Division's coronagraph telescopes called the Wide-Field Imager for Solar Probe, or WISPR, being the only imager.
