solar filaments

    Still there. The above is a image of solar filaments, one taken on May 28th and the other in June, a month later. The filaments have gone round the sun in one revolution and show signes of change.

Venus and runaway global warming

It seems that the consensus and much quoted hypothesis that the high temperatures on Venus are the result of runaway global warming caused by lots of co2 in its atmosphere might have taken a bit of a nose dive this week. The story can be viewed in a variety of places - see for instance

The ESA mission to Venus spotted hot spots on IR images after earlier noting large changes in sulphur levels (see also ...

moon dust

At ... apparently, the moon is engulfed in a permanent, but lopsided, cloud of dust that increases in density when annual meteor showers such as the Gemenids, occur.

liquid sulphur

At .... a story sent in by member Gary (and can also be found at PhysOrg). The earth's core has large quantities of sulphur - ten times the amount in the rest of the planet.


At .... French researchers have created a computer model that is meant to explain the massive heat in the Sun's corona. Apparently, solar physicists have been perplexed by why the corona is millions of degress hotter than the Sun's actual surface. So, the idea of the model is to simulate how that might occur. It involves a magnetic field on the surface of the Sun and Alfven waves generated inside the chromosphere, etc.

slumber over

The Philae Lander that was positioned on Comet Churyumov-Gerasimenko has woken from its slumber and is now in contact with mother ship, Rosetta(according to BBC News on Sunday 14th June. The game is now on.

Meanwhile, at ... the comet remains active after nightfall, it has been noted. Jets of dust and gas are still being emitted even when the Sun is not beaming in the direction of the comet. Is this telling mainstream something?

solar cycles

At ... by Madhulika Guhathakurta and Tony Phillips (published in Space Weather, May 2013) and concerns the 11 year solar cycle (which was discovered 150 years ago). It seems, according to the authors, many people, including a goodly proportion of scientists, have a simplistic view of the solar cycle. It has a maximum (usually the mid point of the 11 years) and a minimum (the early stages and the later stages) - but this hides the fact the Sun is highly active all the time - not just at maximum.


At .... Tim Cullen has sparked interest in this offering as his article (see the link) has been reproduced elsewhere on the blogosphere - such as at ... I can just about remember the furore surrounding Lovejoy as it approached the Sun and the consternation as it failed to live up to what was expected.


At .... and ... Roger Tall Bloke and guests (such as Old Brew) have been discussing, over the years, the link up between the planets of the solar system and the movement of the Sun around its barycentre. As such, they have received little encouragement from elsewhere on the blogosphere and the drawbridge has been pulled up at the castle gates of consensus science.

filaments on the Sun

  at ... we have an image of giant filaments on the face of the Sun. Filaments are said to be cooler clouds of solar material suspended above the Sun's surface by powerful magnetic forces. Filaments can float for days without altering a great deal. They can erupt, releasing material that then rains back down on the surface of the Sun - or is blasted into space.
