The Terra satellite flew over the volcano on June 6 at 14:25 UTC (10:25 a.m. EDT). The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured a visible image of the eruption that showed the large ash plume blowing northeast, then to the southeast and over the Atlantic Ocean. The ash plume went at least as high as six miles on June 4 when it erupted, according to CNN International. Some 3,500 people were evacuated.

The Geostationary Operational Environmental Satellites called GOES-13 and GOES-11 also captured images of the volcano from a different vantage point in space that revealed the plume was visible from even farther away.
GOES-13 monitors the eastern U.S. and the Atlantic Ocean, while GOES-11 monitors the western U.S. and eastern Pacific Ocean. The GOES-11 satellite image, taken from the farthest vantage point of any of the satellites, still showed the triangular-shaped plume, even from its position over the western U.S., despite the large distance.
The GOES satellites are managed by NOAA, and imagery and animations are created with the GOES satellite data at NASA's GOES Project located at NASA's Goddard Space Flight Center, Greenbelt, Md.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
