How Sonic Technology Is Advancing Wind Detection on Mars

American Institute of Physics — Fri, 16 Aug 2024 07:21:06 +0000

Mars’s hostile environment presents significant challenges for measuring wind speeds, but new advancements are making it possible to collect more accurate data. Researchers have developed a novel sonic anemometric system using piezoelectric transducers, enabling faster and more precise measurements of Martian winds. This technology, which could measure up to 100 wind speeds per second, represents [...]

Aeolus Space Mission Goes Public – Already Hailed a Success

European Space Agency (ESA) — Tue, 12 May 2020 11:58:56 +0000

Delivering new information about Earth’s winds, ESA’s Aeolus mission has already been hailed a success. Today, this remarkable satellite mission has yet again achieved new heights: its data are now being distributed publicly to forecasting services and scientific users in less than three hours of measurements being made from space. Aeolus is one of ESA’s [...]

Synchronization in a Decentralized Power Grid

Max Planck Institute — Thu, 13 Sep 2012 15:48:39 +0000

As large power plants are replaced by multiple photovoltaic panels on roofs, biogas systems on fields, and wind turbines on hills and offshore, scientists now believe that synchronization in a decentralized power grid may actually be easier than previously thought, as a grid with many generators finds its own shared rhythm of alternating current. Renewable [...]

Gigantic Downdraft Energy Tower Planned Near US-Mexico Border

SciTechDaily — Tue, 29 May 2012 14:42:58 +0000

Scientists are planning to build a massive type of new power generator in southwestern Arizona, which relies on evaporative cooling to create wind. It should deliver enough energy to power a medium to large city with no negative environmental impact. The downdraft energy tower relies on the principle that cool air will sink while hot [...]

NASA’s Chandra Finds 20 Million MPH Wind

NASA — Wed, 22 Feb 2012 09:27:36 +0000

Researchers recently made two unanticipated findings when making observations from NASA’s Chandra X-ray Observatory. They clocked the fastest wind ever seen blowing off a disk around the stellar-mass black hole IGR J17091, twenty million miles per hour, and found that the wind may be carrying away more material than the black hole is capturing. Astronomers [...]

Crab Nebula Pulsar Abrupt Acceleration is Ultrarelativistic

SciTechDaily — Sat, 18 Feb 2012 10:16:16 +0000

The Crab Nebula (NGC 1952) is easily visible through small telescopes, which has allowed astronomers to observe its growth and evolution, ever since its birth in the stellar fires of the supernova that created it became visible in 1054. In 1968, a pulsar was found at the center of the nebula. The rapidly rotating neutron [...]
