Blast a Black Hole

At https://phys.org/news/2020-09-blast-black-hole.html ... more properly, how to have a blast like a black hole. Researchers at Osaka University have successfully used short but powerful laser blasts to generate magnetic field re-connections inside a plasma. It has to be recognised the magnetic re-connection used is artificial as well as the plasma. The idea is to imitate them in order to learn more about them. The experiment is said to lead towards a more complete theory of X-ray emissions from the universe - and these include black holes.

September 1st

At https://spaceweather.com (September 1st 2020) it would seem that on September 1st 1859 a ferocious solar storm engulfed our planet - breaching the magnetosphere, to a degree. This was the so called Carrington Event, named after solar scientist Richard Carrington, who witnessed the flare that set it in motion. Auroras reached as far south as Cuba, the Bahamas, and Hawaii, and set fire to telegraph stations etc. It is welldocumented in the West. However, it seems there were other equally potent flares that caused a problem.

Giant Halo

At https://phys.org/news/2020-08-hubble-giant-halo-andromeda-galaxy.html ... NASA sientists, using the Hubble Space Telescope, have mapped out an immense envelope of gas, called a halo, surrounding the Andromeda galaxy, the nearest galaxy to the Milky Way. It is a nearly invisible halo of diffuse plasma that extends halfway towards our own galaxy, the Milky Way. This actually implies Andromeda's halo is actually banging up against the halo of our galaxy.

Night Glow

At https://spaceweather.com (26th August 2020) ... earth has entered a stream of high speed solar wind, not from a sun spot as the face of the sun is blank at the moment, but from a hole in the sun's atmosphere. Minor geomgnetic storm was expected - and this duly occurred.

California on Fire

Plasma Jets

At https://phys.org/news/2020-08-black-hole-powers-jet-magnetic.html ... here we have an admission that the black hole in the heart of galaxies has an electro-magnetic connection. The downside is that it is presented as a way to keep the black hole mainstream hypothesis alive and kicking. A sort of kick back if you like. The discovery of a jet of plasma shooting out of the centre of galaxies has caused a certain  amount of angst, it would seem. We are told that a black hole powers a jet by magnetic flux.

Pothole in Space

Sent in by William. At www.yahoo.com/news/pothole-space-evolving-dent-earths-141150074.html ... there is an evolving dent in earth's magnetic field over South America and the South Atlantic. NASA is said to be worried as it  presents problems for satellites. The South Atlantic Anomaly is a weak spot in the earth's magnetic field, it is thought. It seems to be growing. Splitting into two lobes ...

Glaciers on Mars

As expected, this subject has popped up on Thunderbolts. A post by Stephen Smith at www.thunderbolts.info/wp/2020/08/07/martian-glaciers/ ... and as one would think they have a completely contrary take on glaciers, or former oceans and rivers, on Mars. He makes the point that earth is a water planet and it is thought that for life to exist on Mars there must have been water there at one time or another. Water is of course an essential ingredient if humans colonise the red planet.

Magnetic Fields in the Universe

At https://phys.org/news/2020-07-cosmic-magnetic-field-galaxy-ngc.html ... spiral galaxies have sprawling magnetic fields. The process of how they aquired them is not understood. However, a new study claims galaxy wide magnetic fields are in some way connected to supernova explosions and even to star formation. When evaluating the data beamed back from NGO4217, a galaxy which resembles the Milky Way, they found an X shaped magnetic field structure extending far out of the galaxy disc. In addition, they also found a helix structure and two large bubble structures.

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.
