Water on the Moon

At ... that scientists think they have found evidence of water in the interior of the Moon. The origin of water in the interior is a mystery - see ... is derived from satellite data and the idea water can be found in the interior of the Moon raises some interresting questions about the formation of the Moon, on the one hand, and how much water is in the solar system.

Jupiter Aurora

At ... which is posed as an unusual occurrence but presented as Jupiter revealing itself as a planet on steroids - see also ... where the blog post is derived. Jupiter's aurorae get weirder than ever, we are told. The Juno mission's recent images of the Great Red Spot may be spectacular but in June Juno flew over the poles of Jupiter and detected electrically charged particles flying upwards.

water worlds

At ... you have heard of the Expanding Earth thoery - now we have expanding galaxies. Einstien's theory of gravity. it begins. may have to be re-written after researchers at St Andrews University in Scotland found a gigantic ring of galaxies moving away from each other at a much faster rate than the theory allows.


At ... researchers at the University of Colorado Boulder have been investigating the mysterious geology of Mars - the smooth landscape in the north as opposed to the cratered high elevation in the south. They are suggesting a colossal impact with an asteroid was the most likely cause, ripping a chunk out of its northern hemisphere and creating a ring of rocky debris around Mars that may later have clumped together to form the moons, Phobos and Deimos. This idea is not new and a similar asteroid impact theory was touted over 30 years ago.

solar quiet

At ... two researchers from Aberystwyth University in Wales have used data from NASAs Solar Dynamics Observatory to look at the quiet sides of the solar corona. Most research has centred on the more active central band of the solar sphere where sun spots are more likely to occur. One thing the researchers wee looking at was extreme ultraviolet irradiance (EUV)  and they expected big differences betwen the quiet side and the active hot spots.

Pulsar Glitches

At ... modeling upsets theory. A pulsar in a far away galaxy send out x-ray beams that pass earth every 1.37 seconds. Scientists originally thought it was a massive black hole - but it pulsed. Hence it is now designated as a pulsar. Is this all the difference between a hypothetical black hole and a pulsar?

Frozen Smoke

Noctilucent cloud activity is occurring over Europe in early July. See July 3rd 2017 ...

Halton Arp

Book out on Halton Arp. It includes the story of his disagreement about the nature of red shift. The editors are Martin Kokus and Christopher Fulton. The title is 'The Galileo of Palomar: essays in memory of Halton Arp' priced at £10.50 on Amazon. Robert Farrar provided the link - ....

Asteroid Day

At .... we have live streaming from a conference in Luxembourg on Friday the 30th June (2017). Experts will be there to answer questions via social media etc. Supporting events will take place in 70 other countries and the idea is to bring to the public's attention the threat from asteroids and meteors impacting with the Earth and its inhabitants. Why they want to publicise this issue at this point in time is perhaps a mystery - or are they seeking to dispel some of the alarmist web sites regarding asteroid horror stories.


Interesting read at ... modelling the Sun's surface has been difficult. Wild jets of solar material burst forth from the Sun's surface all the time, erupting as fas as 60 miles a second. They can reach 6000 miles high prior to collapsing back down to the surface/ These are known as spicules - and solar scientists have found difficulty in replicating them on their super computers. However, it seems they have now succeeded - see the phenomenon below.
