electric tomatoes

Gary sent in the link to https://phys.org/news/2020-07-electrical-tomato.html ... it seems the soil beneath our feet is alive with electrical signalling. These provide signals among plants, such as tomatoes planted in rows, which have been detected by a professor of electrical and computer engineering. Is it plant communication? What are they telling each other. Well, it would seem that mycorrhizal fungi plays a role. Fungi is a very old life form. Gardeners are encouraged to add mycorrhizal fungi when planting trees and shrubs in order to assist in root growth.

Are they waking up

Seems like mainstream might be waking up to electro-magnetism in space. Gary sent in a link to www.quantamagazine.org/the-hidden-magnetic-universe-begins-to-come-into-... ... which concerns magnetic fields in space. Magnetism permeates entire galaxy clusters it would seem, including the space between galaxies. Invisible field lines sweep through inter galactic space like the grooves of fingerprints on your hands. Last year astronomers had a close look at a region of space that had sparse sign of stars or other cosmic bodies.

Sun Spot Cycle

Tall Bloke again. At https://tallbloke.wordpress.com/2020/06/27/motions-in-the-sun-reveal-inn... ... motions in the Sun are said to reveal the inner workings of the sunspot cycle. We are told ionised gas, or plasma, moves towards the poles of the surface of the Sun as well as towards the equator, at the base of the convection zone (see also https://phys.org/news/2020-06-motions-sun-reveal-sunspot.html ...). The Sun's magnetic activity follows an 11 year cycle. Over the course of those 11 years the activity comes - and it goes.

UFOs and Solar Activity

Interesting  post at https://tallbloke.wordpress.com/2020/06/28/mysterious-lights-seen-geomag... ... mysterious lights may be a geomagnetic link to earthquakes. Paul Devereux wrote a couple of books a few decades ago on the subject of Earth Lights and their association with seismic phenomena. It seems that he might at last be recognised as providing an intuitive theory on UFOs and what they might mean. Or at least the kind of lights that pulsate and move and dart around as seen by many eyewitnesses over the years.

Global Magnetic Anomaly

At https://spaceweather.com (June 26th 2020) as we are still in solar minima, in transit between two solar cycles, earth's magnetic field has been relatively quiet. On June 23rd inmstruments picked up a magnetic anomaly reports Stuart Green of Preston. For over 30 minutes the local field oscillated like a sine wave (see link above for graph). No sign of any solar wind eruptions reported from NOAA. Nothing. The same oddity was picked up in Norway by another amateur researcher using a magnetometer.

distance measurements and cosmology

Robert also sent in this link to https://phys.org/news/2020-06-distance-bolster-basic-universe.html ... new distance measurements bolster challenge to basic model of universe. A new set of precision measurements using a modern telescope array suggest cosmologists need to revise the standard model of the universe. Or that is the big headline. What do they mean by this. Some sort of tinkering with the model. Robert is sceptical. He adds, perhaps they should admit their consensus model does not work. At all.

Plasma Sun

At https://phys.org/news/2020-04-images-reveal-fine-threads-million-degree.... ... researchers at the University of central Lancashire unveil the highest ever resolution images of the Sun - and provide a clue on what it shows. Its outer layer is filled with incredibly fine magnetic threads which are themselves filled with extremely hot million degrees plasma. The ultra sharp images were  taken by NASAs High Resolution Coronal Imager. It can pick out structures in the Sun's atmosphere as small as 70km in size - or 0.01% of the Sun's surface.

Saturn's Atmosphere

Robert sent in this link to https://phys.org/news/2020-04-saturn-atmosphere-hot.html .... What makes Saturn's atmosphere hot? The same question can also be aimed at Jupiter, Uranus and Neptune. The atmospheres of the gas giants are at least as warm as that of the earth - yet they are situated much further away from the Sun. New analyses of data from Cassini indicated one explanation that may have traction. Auroras at the poles of those planets = electric currents triggered by interactions between the solar wind and charged particles from Saturn's moons.

The Pheasant Aurora

Japanese sky watchers, back in the year 620AD, recorded a streak of red light in the night sky and compared it with the colourful tail of a pheasant. See https://phys.org/news/2020-03-modern-science-reveals-ancient-secret.html ... aurora do not usually look like pheasant tails - so what was it. It seems it was as Japan back then was 33 degrees in 620 compare to 25 degrees today. Not sure what that means but they say that implies it was well within the area that would be affected by a strong magnetic storm.

Gas Blob

Sent in by Robert a few days ago. Data from NASAs Voyager 2 flyby of Uranus 30 years ago has been reconsidered and they have found the signature of a massive bubble that may have stolen a blob of the planet's gassy atmosphere. Scientists think it is a plasmoid, a structure that was not properly understand in 1986. Now, plasmoids are reasonably well researched and what they have is a bubble of plasma - a soup of charged particles. The spacecraft actually ploughed its way through the plasmoid - which was as extensive as 250,000 miles across. A big bubble then, from a big planet.
