Conflict in space doesn’t always look like ‘Star Wars’

Astronomers find ‘cannonball pulsar’ speeding through space

Astronomers using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) have found a pulsar speeding away from its presumed birthplace at nearly 700 miles per second, with its trail pointing directly back at the center of a shell of debris from the supernova explosion that created it. The discovery is providing important insights into how pulsars -- superdense neutron stars left over…

NASA Television to Air Three Upcoming Spacewalks, Preview Briefing

Four astronauts are preparing for their first spacewalks outside the International Space Station, scheduled for March 22, March 29 and April 8.

Levitating objects with light

Though still theoretical, the work is a step toward developing a spacecraft that could reach the nearest planet…

NASA’s Fermi Satellite clocks ‘cannonball’ pulsar speeding through space

Astronomers found a pulsar hurtling through space at nearly 2.5 million miles an hour -- so fast it could travel the distance between Earth and the Moon in just 6 minutes. The discovery was made using NASA's Fermi Gamma-ray Space Telescope and the National Science Foundation's Karl G. Jansky Very Large Array (VLA). Pulsars are superdense, rapidly spinning neutron stars left behind when a massive…

NASA-NOAA Satellite catches last burst of energy in Tropical Depression 03W

IMAGE: On March 18, 2019 at 1:30 a.m. EDT (0530 UTC), the VIIRS instrument aboard NASA-NOAA's Suomi NPP satellite looked at Tropical Depression 03W in infrared light. VIIRS found coldest cloud... view more  Credit: NASA/NRL Tropical Depression 03W has dissipated in the Northwestern Pacific Ocean, but not without one last show of strength on infrared satellite imagery. NASA-NOAA's Suomi NPP satellite provided an infrared look at…

How heavy elements come about in the universe

IMAGE: For the first time, the fusion of hydrogen and xenon was able to be investigated at the same temperatures as occur in stellar explosions using an ion storage ring. view more  Credit: Mario Weigand FRANKFURT. Heavy elements are produced during stellar explosion or on the surfaces of neutron stars through the capture of hydrogen nuclei (protons). This occurs at extremely high temperatures, but at relatively…

Spiraling giants: Witnessing the birth of a massive binary star system

Scientists from the RIKEN Cluster for Pioneering Research in Japan, Chalmers University of Technology in Sweden and the University of Virginia in the USA and collaborators have made observations of a molecular cloud that is collapsing to form two massive protostars that will eventually become a binary star system. While it is known that most massive stars possess orbiting stellar companions it has been unclear…

NASA sees Savannah lose its tropical eye

IMAGE: On March 18, 2019, the VIIRS instrument aboard NASA-NOAA's Suomi NPP satellite captured a visible image of Tropical Cyclone Savannah that showed its eye had become cloud-filled. view more  Credit: Credit: NASA Worldview, Earth Observing System Data and Information System (EOSDIS) Tropical Cyclone Savannah weakened and "lost" its eye as high clouds filtered over it. NASA-NOAA's Suomi NPP satellite passed over the Southern Indian Ocean…

Satellite sees Tropical Cyclone Savannah moving away from Indonesia

IMAGE: NASA-NOAA's Suomi NPP satellite passed over the Southern Indian Ocean and captured a visible image of Tropical Cyclone Savannah on March 15, as it continued to move away from Indonesia.... view more  Credit: NASA Worldview, Earth Observing System Data and Information System (EOSDIS). Tropical Cyclone Savannah continued to move in southerly direction in the Southern Indian Ocean, and move away from Indonesia. NASA-NOAA's Suomi NPP…
