Unprecedented Map of the Sun’s Magnetic Field Created by CLASP2 Space Experiment
Every day space telescopes provide spectacular images of the solar activity. However, their instruments are blind to its main driver: the magnetic field in the outer layers of the solar atmosphere, where the explosive events that occasionally affect the Earth occur. The extraordinary observations of the polarization of the Sun’s ultraviolet light achieved by the CLASP2 mission have made it possible to map the magnetic field throughout the entire solar atmosphere, from the photosphere until the base of the extremely hot corona. This investigation, published today in the journal Science Advances, has been carried out by the international team responsible for this suborbital experiment, which includes several scientists of the POLMAG group of the Instituto de Astrofísica de Canarias (IAC).
The chromosphere is a very important region of the solar atmosphere spanning a few thousand kilometers between the relatively thin and cool photosphere (with temperatures of a few thousand degrees) and the hot and extended corona (with temperatures above a million degrees). Although the temperature of the chromosphere is about one hundred times lower than that of the corona, the chromosphere has a far higher density, and thus much more energy is required to sustain it. Moreover, the mechanical energy necessary to heat the corona needs to traverse the chromosphere, making it a crucial interface region for the solution of many of the key problems in solar and stellar physics. One of the current scientific challenges is to understand the origin of the violent activity of the solar atmosphere, which on some occasions perturb the Earth’s magnetosphere with serious consequences for our present technological world.
Why Materialism is a Flatlander Philosophy
When enough anomalies accumulate over time, paradigms change. We may be close to that inflection point right now. At this juncture of technoscientific progress, the boldest of us may admit that we’re overdue for the next post-materialist paradigm: Conventional scientific method is already bankrupt and needs to be supplanted by AI-powered quantum neo-empiricism, computational thinking and the cybernetic approach to reality.

Incredible Sneak Peek of Mars Landing Sent Back
The six-wheeled robot’s latest data since touching down yesterday include a series of images captured as the rover’s “jet pack” lowered it to the ground.
Less than a day after NASA ’s Mars 2020 Perseverance rover successfully landed on the surface of Mars, engineers and scientists at the agency’s Jet Propulsion Laboratory in Southern California were hard at work, awaiting the next transmissions from Perseverance. As data gradually came in, relayed by several spacecraft orbiting the Red Planet, the Perseverance team were relieved to see the rover’s health reports, which showed everything appeared to be working as expected.
NASA’s Perseverance successfully touches down on Mars
NEW: A new photo from NASA rover Perseverance’s “jetpack” shows the surface of Mars just before it touched down on the Red Planet.

NASA is expected to land its Perseverance rover on Mars this Thursday,.
Now that NASA’s Perseverance Mars Rover successfully landed on the Red Planet after a nearly seven-month journey
mission experts will talk about the robotic scientist’s touchdown in the most challenging terrain on Mars ever targeted.
Perseverance, which launched July 302020, will search for signs of ancient microbial life, collect carefully selected rock and regolith (broken rock and dust) samples for future return to Earth, characterize Mars’ geology and climate, and pave the way for human exploration beyond the Moon.

NASA rover lands on Mars to look for signs of ancient life
A NASA rover streaked through the orange Martian sky and landed on the planet Thursday, accomplishing the riskiest step yet in an epic quest to bring back rocks that could answer whether life ever existed on Mars.
Researchers construct the smallest microchips yet using graphene nano-origami
Physicists from the University of Sussex have created what they called the tiniest microchips yet. The little microchips are made using graphene and other 2D materials and a form of “nano-origami.” The technique used in creating the tiny microchips marks the first time any researchers have been able to do this.
Researchers succeeded in making the tiny microchips by creating kinks in the structure of graphene to make the nanomaterial behave like a transistor. In their study, the team showed that when a graphene strip is crinkled in a specific way, it behaves like a microchip only about 100 times smaller than a conventional microchip. New construction methods are needed for microchips because traditional semiconducting technology is at the limit of what it can do.
The researchers believe that using the materials in their technique will make computer chips smaller and faster. The technology is dubbed “straintronics” and uses nanomaterials rather than electronics, allowing space for more chips inside a given device. The researchers believe everything we want to do with computers to speeding them up can be done by crinkling graphene.
