  Bethesda, MD (SPX) Apr 09, 2019 Soon, the number of active satellites in low-Earth orbits (LEO) will likely increase by a factor of 10 to 15. Just last week, Amazon announced it has filed for a license to operate a constellation of 3,234 satellites in low orbits. Several other entrepreneurial companies are either planning to launch or already have launched part of huge new constellations. Each of these companies hopes to eventually establish constellations containing hundreds or thousands of broadband and other satellites, and a ... read more |

 Hampton, VA (SPX) Apr 01, 2019 
It probably goes without saying, but this isn't your everyday satellite dish.
In fact, it's not a satellite dish at all. It's a high-gain antenna (HGA), and a future version of it will send and receive signals to and from Earth from a looping orbit around Jupiter.
The antenna will take that long journey aboard NASA's Europa Clipper, a spacecraft that will conduct detailed reconnaissa ... more |

 Santa Cruz CA (SPX) Apr 09, 2019 
Metallic asteroids are thought to have started out as blobs of molten iron floating in space. As if that's not strange enough, scientists now think that as the metal cooled and solidified, volcanoes spewing liquid iron could have erupted through a solid iron crust onto the surface of the asteroid.
This scenario emerged from an analysis by planetary scientists at UC Santa Cruz whose investi ... more |

Scientists have used simulations to show that the photons emitted by long gamma-ray bursts, the most powerful electromagnetic phenomena in the universe, originate at the visible surface of high-speed jets emitted by exploding stars.
Gamma-ray bursts release as much energy in a second or so as the Sun will release over its entire lifetime. Scientists now know that one of the types, long bur ... more |
