Radio Flash, Dark Energy

At ... a new telescope in South Africa, the HIRAX, has two goals. One is to study the evolution of dark energy by tracking neutral hydrogen gas in galaxies. The second goal is to detect and locate mysterious radio flashes known as fast radio bursts.

Yosemite Granites

This comes from ... Yosemite granite tells a different story about Earth's geological history, is the blurb. What do they mean? Granites in Yosemite National Park contain minerals that crystalised at a much lower temperature than previously thought possible. Apparently, this upends our understanding of how granites form - which seems very important (but is it?). Granites are igneous rocks - mainly quartz and feldspar. They are the link between igneous processes within the Earth and volcanic rocks that solidified at the surface.

Wandering Stars

At ... Aboriginal tradition describes the complex motion of the planets, the wandering stars of the sky. This may sould a bit like Robert Temple and his 'Sirius Mystery' but no - this is serious science (projected out of Aboriginal myth). The Greeks called the planets 'anteres planetai' (wandering stars) as they wander across the sky relative to the fixed stars. Now we have some new research that says Aboriginals had a much earlier tradition of the moving planets.

Oort Clouds

At https://phys.o9rg/print453635544.html ... Oort clouds around other stars should be visible in the cosmic microwave background. For decades astronomers have theorised beyond the edge of the solar system there lies a massive cloud of icy planetisimals known as the Oort Cloud. This cloud, it is thought, is where long term comets originate - but to date no evidence has been provided to confirm its existence. One reason is that the Oort Cloud is difficult to observe - far away from the Sun and dispersed over a large area.

Elve Giant

At (Sunday 19th August 2018) - a giant elve over Russia. High above a thunderstorm in central Russia an enormous ring of light appeared in the night sky - caught on camera by Ilya Jonkowsky. Elves appear when a pulse of electro magnetic radiation from cloud to ground lightning propagates upwards towards the base of the ionosphere.


Stellar Fly By

This one caught my attention as it is reminiscent of the recent talk by Rupert Holms (see home page of web site). At ... which has the addititional benefit of a few comments.  Could a rogue star passing our solar system disturb the outer ranks beyond Neptune. Oldbrew comments, 'Why does the Kuiper Belt suddenly end? The Kuiper Belt is a huge region of the solar system forming a ring around the Sun just beyond the orbit of Neptune.

Dating Thera Eruption

At ... courtesy of the University of Arizona (dendrochronology unit). An attempt has been made to resolve discrepancies between archaeological and radiocarbon methods of dating the eruption of the Thera volcano by tying up in knots the timeline of ancient Egypt, Crete, Greece, Turkey and the Levant.

Mini Mammoths

Sent in by Robert - two posts at the Daily Mail online site - ... and ... to which Robert comments, 'new pterodactyl and mini mammoth found. Interestingly, both are at sites of 'mass kill' events ....'.


We have further evidence of upheaval and climate change around 6200BC. The world suddenly cooled leading to a period of drier summers (and presumably colder winters) across much of the northern hemisphere. Early farming communities must have been impacted, we are told, but nothing was known about how they coped with change. The conditions were very much like a short dryas episode - lasting 200+ years. Hence, scientists decided to try and find out by looking at the ruins of the city of Catalhoyuk in central Turkey.
