Asteroids and other things

Robert sent in the link https://astronomynow.com/2018/07/02/dawn-zooms-in-on-vestas-enigmatic-oc... ... the Dawn spacecraft is nearing the Ceres asteroid.

Arrhenius

At https://chaamjamal.wordpress.com/2018/06/29/a-theory-of-ice-age-cycles/ ... an intriguing blog post by Chaam Jamal concerning some ideas by Gerald Marsh, a retired laboratory physicist who challenged mainstream views that ice age cycles were initiated by Milankovitch orbital cycles - and driven by the Arrhenius effect on carbon dioxide (co2). One can instantly see a problem - is the Arrhenius effect real (a hypothesis that has been subsumed into the mainstream narrative). The Arrhenius hypothesis goes back to 1896 (and before that we had Tyndal in 1861).

Animals and Global Warming

This new paper was so way out that Antony posted it at https://wattsupwiththat.com/2018/07/02/claim-worlds-first-animals-caused... ... alarmists can blame virtualy anything for global warming, and they do, but one wonders what lies behind the writing of this one. Are the authors the recipients of dosh - or are they really so obsessed with the subject that they feel able to write just about anything, even at a point in earth history that very little is known about.

Sea Level Rise and Alarmism

At www.sepp.org (the Science and Environmental Policy Project, which has similarities to the GWPF over here in the UK) has a regular newsletter. On July 1st the subjectg was sea level research and something controversial climate scientist Richard Lindzen said in an interview. Since 1979 sea level has been measured by satellites - but the accuracy of it is compromised by the actual shape of the Earth. Whilst satellites also shown an increased rate in the rise of sea levels the measurements are uncertain because of several factors (such as the one above).

Eta Carinae

Big news this week on the astronomy front - NuSTAR mission proves superstar Eta Carinae shoots out cosmic rays (see https://phys.org/print449835766.html ... a study using data from NASAs NuSTAR space telescope suggests Eta Carinae, the most prominent and massive stellar system within 10,000 light years, is accelerating particles of high energy - some of which arrive in our solar system.

Uranus in Collision

Sent in By Robert - www.centauri-dreams.org/2018/07/03/uranus-orbital-tilt-from-a-cataclysmi... .... the excessive tilt in the orbit of Uranus was caused by a cataclysmic collision, we are informed. This seems to have been provoked by the discovery that exoplanets can have tilted orbits. In our solar system the Earth is titled at 23 degrees and Uranus by 98 degrees - but in contrast Mercury has a small tilt, at only 0.3 degrees. The amount of obliquity affects seasonality.

Comet and Oxygen

At https://phys.org/print449835597.html ... molecular oxygen found on Comet Churyumov-Gerasimenko back in 2016 is not produced on its surface according to an analysis of Rosetta data. Instead, it must have an origin in the interior of the comet. Instruments onboard Rosetta analysed the comet's coma and revealed it had water, carbon monoxide, carbon dioxide, and molecular oxygen. On Earth oxygen is essential for life - and it is thought to be produced by photosynthesis. It seems oxgen on Earth may also have an origin inside the planet - topped up by photosynthesis.

Comet Brightness

At http://spaceweather.com (July 4th 2018) ... Comet PanSTARRS, the so called Green Comet, a green blob against the backdrop of stars, has just increased in brightness - dramatically. It actually brightened sixteen fold - according to Michael Jager, an Austrian amateur astronomer (in the late hours of July 2nd).

Validating Einstein

In Electric Universe circles we hear a lot about Einstein being wrong about this and that - and the failure of his theories (and the weakness of gravity and all that). At www.scientificamerican.com/article/einsteins-greatest-theory-validated-o... .... which is saying something quite opposite. Astrophysicist Tom Collett set out to disprove Einstein, he assures us, but instead found corroboration. He set up an experiment to test one aspect of Einstein's Theory of General Relativity (first published in 1915).

Suffolk Neolithic Trackway

At https://edition.cnn.com/2018/06/28/health/neolithic-site-uncovered-windf... ... brought to you by CNN - but is this fake news? Plans to build a super windfarm have come up with an archaeological site of unusual depth - deep in the heart of Suffolk (eastern England). Most prominent in this news release is the Neolithic trackway - dated at 2300BC. There was also the skull of an auroch (4000BC) as well as pottery from various periods, buildings (or their outlines), lots of bones, coins and various other interesting bits and pieces.
