Using seismic array-processing to enhance faint signals in the Apollo data, the scientists were able to deduce that the lunar core is iron-rich, and consists of a solid inner ball of about 240 km in radius and a 90 km-thick fluid shell. The re-analysis also suggests that the core ...
Describes the Giant Metrewave Radio Telescope (GMRT) located in west-central India. Goals of GMRT; Antennas and dishes; Comparisons to the Very Large Array (VLA) in Mew Mexico; New telescope wavelengths; Plans for ways to best use the GMRT...
Both surveys were carried out at 1.4 GHz with the Very Large Array (VLA) in New Mexico, USA, which has led to the fact that the majority of known GRS were found in the northern celestial hemisphere, which is also largely covered by deep imaging and spectroscopic surveys such as the ...
The dazzling array of more than 1500 insect specimens has been sampled during open-cast mining between the last decades of the 19th and the first decades of the 20th century [138]. About 1200 insect fossils are blattoids [139]. As a result, the Commentry entomofauna is the world’s ...
1981 January: entire array completed nearly one year ahead of schedule! The total cost was $78,578,000 (in 1972 dollars), roughly $1 per tax-payer at the time; the project was completed within the allotted budget. Location: Plains of San Agustin, west of Socorro, New Mexico. ...
In optical images from theHubble Space Telescope's Wide Field Camera 3, Hercules A seems to be a quite ordinary galaxy, seen glowing, yellowish in color at the center of this image. But superimposedradio datafrom the Very Large Array (VLA) in New Mexico shows jets that would be invisible...
With its three Arizona-based production facilities and its state-of-the-art robotic application system, Severtson has massive production capabilities and an unusually wide array of screens. The screens range in size from massive movie theaters, comfortable home theaters, and everything in between. ...
The air gun and the hydrophone array streamer were towed at depths of 2 and 3 m below sea surface, respectively to maintain high frequency contents in the seismic signals. The received reflection signals were recorded at an 1-msec. sampling rate by the DAQlink III seismograph (Seismic ...
