Astronomy news


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.

Planet X Again

At ... an online paper currently available at is written by two researchers at the University of Arizona's Lunar and Planetary Laboratory, and claims there may be a planet sized body (somewhere in the region of the size of Mars or the Earth, orbiting in the outer solar system. The hypothesis comes about as a means to explain some orbital inconsistencies amongst distant bodies in the Kuiper Belt region.

day time meteor shower

At June 6th 2017 we have news of a day time meteor shower this week as the Earth is passing through a stream of dusty debris from - no one knows for sure.

Theory of Inflation

Another one of Jovan's links. Go to ... which is dated back to February 2017. It concerns the origin of space and time, as outlined in 'Pop Goes the Universe' - which argues against mainstream consensus theory of Big Bang and Expansion. The theory presented is not too different from the preferred explanation in spite of the controversy engendered. The universe began with a bounce rather than a bang (or explosion), from a previously contracting universe.
