Researchers recently found that a few years back, they “slept” through a hurricane. On analyzing weather satellite data from 2,014 scientists discovered evidence of a hurricane from space that pushed plasma toward Earth’s upper atmosphere. Though these events are invisible to the eye, the evidence reveals that they’re not uncommon. Understanding more about them could help to protect satellite and communications systems from disturbance and preserve radar and GPS output for life below on the planet’s surface.
Satellites in orbit around the planet gather immense amounts of data on environmental and climate activity. A recent publication in Nature Communications explains how the first hurricane from space was discovered through analysis of data gathered back in August 2014.
The research team looked at recently released files containing measurements taken by four satellites in the Defense Meteorological Satellite Program. From their analysis, the scientists created a 3D image that showed the hurricane from space forming features similar to what we’re familiar with in Earth’s lower atmosphere. A press release in Science Daily describes it as a gigantic spiral of plasma, with its arms swirling counterclockwise above the North Pole.
By studying the topography and mineral composition of a portion of the Arabia Terra region in northern Mars, scientists recently found evidence for thousands of “super eruptions,” which are the most violent volcanic explosions known.
These brightly colored robotic boats seem to have a death wish.
The brightly-colored robotic boats made by Saildrone seem to have a death wish.
Saildrone makes autonomous ocean vessels to study the environment. This summer, the Silicon Valley startup sent five of its vessels directly into the path of hurricanes in the Atlantic Ocean. While airplanes can fly through hurricanes, the screaming winds kick up such huge waves that attempting to sail boats right into them is something best to be avoided.
Saildrone’s vessels are uncrewed, and built to survive hurricane winds and huge waves. Scientists are excited that the vessels could improve our understanding of how storms intensify.
When a cloudy plume of ice and water vapor billows up above the top of a severe thunderstorm, there’s a good chance a violent tornado, high winds or hailstones bigger than golf balls will soon pelt the Earth below.
A new Stanford University-led study, published Sept. 10 in Science, reveals the physical mechanism for these plumes, which form above most of the world’s most damaging tornadoes.
Previous research has shown they’re easy to spot in satellite imagery, often 30 minutes or more before severe weather reaches the ground. “The question is, why is this plume associated with the worst conditions, and how does it exist in the first place? That’s the gap that we are starting to fill,” said atmospheric scientist Morgan O’Neill, lead author of the new study.
It was a moment three years in the making, based on intensive research and design work: On Sept. 5 for the first time, a large high-temperature superconducting electromagnet was ramped up to a field strength of 20 tesla, the most powerful magnetic field of its kind ever created on Earth. That successful demonstration helps resolve the greatest uncertainty in the quest to build the world’s first fusion power plant that can produce more power than it consumes, according to the project’s leaders at MIT and startup company Commonwealth Fusion Systems (CFS).
That advance paves the way, they say, for the long-sought creation of practical, inexpensive, carbon-free power plants that could make a major contribution to limiting the effects of global climate change.
“Fusion in a lot of ways is the ultimate clean energy source,” says Maria Zuber, MIT’s vice president for research and E. A. Griswold Professor of Geophysics. “The amount of power that is available is really game-changing.” The fuel used to create fusion energy comes from water, and “the Earth is full of water—it’s a nearly unlimited resource. We just have to figure out how to utilize it.”
26,000 Years ago, humans hunted gigantic wooly mamoths, 600 miles above the arctic circle. The fact that we had such human settlements so far north, jives well with Bal Gangadhar Tilak’s hypothesis of a northern origin of all Indo-European language cultures. Tilak, the “Ben Franklin” of modern India and predecesor of Mahatma Gandhi wrote the book “The Arctic Home in the Vedas,” where he developed his hypothesis based of the Vedas verses, that what was described therein could only have happened above the arctic circle at a time when the climate there was milder. He proposed that as the ice age set in, this culture was forced to immigrate southwards, leading to colonization of Eurasia.

A new quantum radar technology developed by a team of Chinese researchers would be able to detect stealth planes, the South China Morning Post is reporting.
The news service reports that the radar technology generates a mini electromagnetic storm to detect objects. Professor Zhang Chao and his team at Tsinghua University’s aerospace engineering school, reported their findings in a paper in Journal of Radars.
A quantum radar is different from traditional radars in several ways, according to the paper. While traditional radars have on a fixed or rotating dish, the quantum design features a gun-shaped instrument that accelerates electrons. The electrons pass through a winding tube of a strong magnetic fields, producing what is described as a tornado-shaped microwave vortex.
New marque Automobili Estrema plans for its first model to reach 200 mph in less than 10 seconds and have a 325-mile range.
Automobili Estrema is a marque soon to become synonymous with extreme technology and performance in the hypercar stratosphere. Founded in 2020—a challenging year by any measure—the company is Italian through and through, though its team members and partners represent a global Who’s Who of leaders within the energy and automotive industries. Founder and CEO Gianfranco Pizzuto, an entrepreneur with an international business background, was the first investor and cofounder of Fisker Automotive in 2007. It was a bold venture into uncharted territory at a time when EVs were experiments and the first Tesla Roadster was still a year away. Now, as head of Automobili Estrema, he and his team have spent a year in virtual collaboration and accomplished what is nothing less than remarkable.
