They admit that “The exact origin of water in the lunar interior is still a big question”, as reports. The article also points out that ‘The idea that the interior of the Moon is water-rich raises interesting questions about the Moon’s formation.’ Perhaps they are suggesting that some prevailing theories might no longer…er…hold water.

A new study of satellite data finds that numerous volcanic deposits distributed across the surface of the Moon contain unusually high amounts of trapped water compared with surrounding terrains.

The finding of water in these ancient deposits, which are believed to consist of glass beads formed by the explosive eruption of magma coming from the deep lunar interior, bolsters the idea that the lunar mantle is surprisingly water-rich.

Scientists had assumed for years that the interior of the Moon had been largely depleted of water and other volatile compounds.


Jupiter is living up to its billing as a ‘planet on steroids’.

Planet Pailly

Last week, the Juno mission flew over Jupiter’s Great Red Spot and sent back some spectacular close-ups. But I’m not ready to talk about that. Not yet. I’m still catching up on the Juno news from two months ago.

Toward the end of May, NASA released a ton of fresh data from Juno, including new information about Jupiter’s auroras. Astro-scientists had previously known about two sources contributing to these auroras: the solar wind and the Io plasma torus. Now Juno may have discovered a third.

As Juno flew over Jupiter’s poles, it detected electrically charged particles flying up.

I can’t emphasize enough how weird this is. I wanted to write about it right away, but I held off doing this post because I was sure I must have misunderstood what I was reading.

Auroras are caused by electrically charged particles accelerated down toward a planet’s magnetic poles. These…

The report at explains that “Even though the moon blocking the sun during a solar eclipse and clouds blocking sunlight to Earth’s surface are two different phenomena, both require similar mathematical calculations to accurately understand their effects.”

It was mid-afternoon, but it was dark in an area in Boulder, Colorado on Aug. 3, 1998. A thick cloud appeared overhead and dimmed the land below for more than 30 minutes. Well-calibrated radiometers showed that there were very low levels of light reaching the ground, sufficiently low that researchers decided to simulate this interesting event with computer models.

Now in 2017, inspired by the event in Boulder, NASA scientists will explore the moon’s eclipse of the sun to learn more about Earth’s energy system. On Aug. 21, 2017, scientists are looking to this year’s total solar eclipse passing across America to improve our modelling capabilities of Earth’s energy.

The author of this theory says “Jupiter and Saturn’s growth naturally pollutes the inner Solar System with water-rich planetesimals. In my mind the mechanism is very clear”. The theory does seem to bear a resemblance to this summary from the Hans Rickman Uppsala Astronomical Observatory.

Water on Earth, Mars and everywhere within the inner Solar System can be traced back to the rapid waist-expanding growth of Jupiter and Saturn, which knocked inwards a local population of icy planetesimals, as Sci-News reports.

This is according to a new model, which could also explain the current makeup of our modern asteroid belt.

Whilst Earth is often described as the blue marble, with over 70% of its surface covered in oceans, seas, rivers and lakes, water actually makes up less than 0.1% of our planet by mass.

Extreme ultraviolet radiation (EUV) is perhaps an aspect of solar activity that gets less attention than it should. The authors make the interesting point in their introduction to the research article that ‘Although the total solar irradiance at Earth varies very little, the relative variance in the EUV is as large as the mean irradiance. This EUV light interacts with Earth’s thermosphere and stratosphere and may affect climate in a “top-down” process in regions such as northern Europe’.

A pair of researchers with Aberystwyth University in the U.K. has used data from NASA’s Solar Dynamics Observatory to learn more about how the sun’s corona behaves over differing stages of its 11-year cycle, reports Bob Yirka at

In their paper published on the open access site Science Advances, Huw Morgan and Youra Taroyan describe attributes of the sun they observed over time and what they discovered about the “quiet corona” and its possible impact on us back here on Earth.


Ned and Karl have finally got some big exposure to the general public for their paradigm shifting breakthrough in geo and astro-physics. World Net Daily front page stories are read by over a million people. This is a great step forward for recognition of their work.

Study blows Greenhouse Theory out of the water

7-9-2017 By Alex Newman for World Net Daily

BOZEMAN, Mont. – A new scientific paper contends the entire foundation of the man-made global-warming theory – the assumption that greenhouse gases warm the atmosphere by trapping heat – is wrong.

If confirmed, the study’s findings would crush the entire “climate change” movement to restrict CO2 emissions, the authors assert

Some experts contacted by WND criticized the paper, while others advised caution.

Still others suggested that the claimed discovery represents a massive leap forward in human understanding – a “new paradigm.”

The paper argues that concentrations of CO2 and other supposed “greenhouse gases” in the atmosphere have virtually no effect on the earth’s temperature.


chickeneditorA long and interesting article about science publishing in the Guardian is largely about the history of Robert Maxwells involvement in science publication, but contains much else of interest besides. A few excerpts:

Many scientists also believe that the publishing industry exerts too much influence over what scientists choose to study, which is ultimately bad for science itself. Journals prize new and spectacular results – after all, they are in the business of selling subscriptions – and scientists, knowing exactly what kind of work gets published, align their submissions accordingly. This produces a steady stream of papers, the importance of which is immediately apparent. But it also means that scientists do not have an accurate map of their field of inquiry.



Back in late 2011, the Talkshop splashed the story on a ‘Unified Theory of Climate’  developed by PhD physicists Ned Nikolov and Karl Zeller. They set out to show that the ‘greenhouse effect’ is not a phenomenon arising out of the absorption and reemission of outgoing long-wave radiation by the atmosphere (as thought for 190 years), but is a form of compression heating controlled by solar radiation and the total atmospheric pressure at the Earth’s surface. Pressure is in turn a product of the gas mass contained in a column of air above a unit surface area, and the planet’s gravitational effect on that mass.

It’s been a long and treacherous road involving many revisions and refinements of the original study. On several occasions the manuscript was rejected unread, but Ned and Karl have finally got their greatly improved and expanded paper published. This latest version is a tour de force strengthened by the rigors of criticism from an army of peer reviewers at several journals along the way.

Using dimensional analysis (a classical technique for inferring physically meaningful relationships from measured data), they show that the long-term global equilibrium surface temperature of bodies in the solar system as diverse as Venus, the Moon, Earth, Mars, Titan and Triton can accurately be described using only two predictors: the mean distance from the Sun and the total atmospheric surface pressure. This type of cross-planetary analysis using vetted NASA observations has not been conducted by any other authors. It represents the first and only attempt in the history of climate science to assess Earth’s surface temperature in the context of a cosmic physical continuum defined by actual planetary-scale observations. The result is a new insight that planetary climates are independent of the infrared optical depth of their atmospheres arising from their composition, and that the long-wave ‘back radiation’ is actually a product of the atmospheric thermal effect rather than a cause for it.



Arctic Ocean

Scientists have surprised themselves by noticing multi-decadal natural variability in the Arctic, and discovering some of its effects, as reports. More than a hint of cyclical warming and cooling is implied, although they try to downplay it.

Is a warmer Arctic a canary of global warming? Since the 1970s the northern polar region has warmed faster than global averages by a factor or two or more, in a process of ‘Arctic amplification’ which is linked to a drastic reduction in sea ice.

But then how to explain a similar rapid warming that occurred during the early 20th century, when the effects of greenhouse gases were considerably weaker than today? And what can we prove about the period, given the scarcity of usable data and observations prior to the 1950s?

Now scientists from Kyoto University and UC San Diego have discovered that this phenomenon occurred when the warming phase—’interdecadal variability mode’—of both the Pacific and Atlantic Oceans coincided.


Much media attention on this new paper this week. Is there a surprise lurking in the details now that the orbit period of the seventh planet has been confirmed?.

What the numbers in the diagram show is the orbits per planet in a fixed period (top row), the conjunctions per planet pair in the same period (second row), and the ratios that represents (third row).

The number of conjunctions of any two planets is the difference between the two orbit numbers in a given period, which in this case is equivalent to just under 1446 Earth days (see data below).

Apart from the obvious symmetry of the ratios, something else arose from the science paper.

It’s unimaginably vast: astronomers say ‘this structure is a 75,000 light-year long filament of gas and dust’. Trying to separate out the effects of gravity and magnetism here should be an interesting challenge.

A magnetic field appears to span the space between the Large and Small Magellanic Clouds, the two dwarf galaxies being consumed by our Milky Way Galaxy, reports Sky & Telescope via

For stargazers in the Northern Hemisphere, it’s easy to forget that the Milky Way is actively consuming two dwarf galaxies. Those in the Southern Hemisphere have a front row seat to watch our galaxy wreak havoc on the Large and Small Magellanic Clouds (LMC and SMC).

But there’s more to the story — the dwarfs are not only gravitationally interacting with the Milky Way but with each other as well.


One high-altitude nuclear test even managed to create its own artificial aurora. Others knocked out orbiting satellites.

Our Cold War history is now offering scientists a chance to better understand the complex space system that surrounds us, says

Space weather — which can include changes in Earth’s magnetic environment— is usually triggered by the sun’s activity, but recently declassified data on high-altitude nuclear explosion tests have provided a new look at the mechanisms that set off perturbations in that magnetic system.

Such information can help support NASA’s efforts to protect satellites and astronauts from the natural radiation inherent in space. From 1958 to 1962, the U.S. and U.S.S.R. ran high-altitude tests with exotic code names like Starfish, Argus and Teak.

The tests have long since ended, and the goals at the time were military. Today, however, they can provide crucial information on how humans can affect space.



The energy that went into making the impact crater is thought to be equivalent to 10 billion Hiroshima A-bombs, as BBC News explains. Nowhere to run/hide/escape.

Scientists who drilled into the impact crater associated with the demise of the dinosaurs summarised their findings so far in a BBC Two documentary on Monday.

The researchers recovered rocks from under the Gulf of Mexico that were hit by an asteroid 66 million years ago. The nature of this material records the details of the event.

It is becoming clear that the 15km-wide asteroid could not have hit a worse place on Earth.


Exoplanets up to 90 times closer to their star than Earth is to the Sun.

Excellent – we outlined this ‘resonance chain’ (as they have now dubbed it) in an earlier post here at the Talkshop [see ‘Talkshop note’ in the linked post for details].

When NASA announced its discovery of the TRAPPIST-1 system back in February it caused quite a stir, and with good reason says

Three of its seven Earth-sized planets lay in the star’s habitable zone, meaning they may harbour suitable conditions for life.

But one of the major puzzles from the original research describing the system was that it seemed to be unstable.

“If you simulate the system, the planets start crashing into one another in less than a million years,” says Dan Tamayo, a postdoc at U of T Scarborough’s Centre for Planetary Science.



Something new for geologists to get their teeth into.

The Falkland Islands may be home to one of the world’s largest craters, reports the IB Times. A new analysis has revealed it has many characteristics of an asteroid impact and may date back to the ‘Great Dying’ extinction event.

About 200 similar large craters have been discovered so far on Earth but there are many other examples of them on other planets including on Venus, Mercury and Mars.

The Falkland Islands structure, which is described in detail in the journal Terra Nova, has a diameter measuring approximately 250 kilometres (150 miles). If it turns out to be an impact crater, this size would make it one of Earth’s largest – comparable to the famous Chicxulub crater discovered in the Yucatan Peninsula in Mexico nearly four decades ago.



Another alleged climate alarm looks more like a damp squib, undermined by new research.

Glacier flow at the southern Antarctic Peninsula has increased since the 1990s, but a new study has found the change to be only a third of what was recently reported, says

An international team of researchers, led by the UK Centre for Polar Observation and Modelling at the University of Leeds, are the first to map the change in ice speed. The team collated measurements recorded by five different satellites to track changes in the speed of more than 30 glaciers since 1992.

The findings, published today in Geophysical Research Letters, represent the first detailed assessment of changing glacier flow in Western Palmer Land—the southwestern corner of the Antarctic Peninsula.

This seems to add weight to the idea that the moving position of the ITCZ can be a useful indicator of natural climate change, in conjunction with other data sources.

The tropical rain belt, also known as the Intertropical Convergence Zone (ITCZ), is in a state of constant migration, as reports.

It continuously changes position in response to the seasons and follows the sun’s zenith, with a slight delay. This in turn determines the wet and dry periods in the tropics and subtropics over the course of the year.

The tropical rain belt therefore effectively controls the climate in most of the tropical and subtropical regions, such as the monsoon season in Southeast Asia and Central America.

An international team of researchers led by Franziska Lechleitner from the Geological Institute at ETH Zurich has proven for the first time that the migration of the tropical rain belt is quite sensitive to even small changes in global temperatures.

A compact model of the heliosphere, supported by the latest data [Credit: Dialynas, et al.]

It seems the interstellar magnetic field is a lot more powerful than scientists expected, as reports.

New data from NASA’s Cassini mission, combined with measurements from the two Voyager spacecraft and NASA’s Interstellar Boundary Explorer, or IBEX, suggests that our sun and planets are surrounded by a giant, rounded system of magnetic field from the sun—calling into question the alternate view of the solar magnetic fields trailing behind the sun in the shape of a long comet tail.

The sun releases a constant outflow of magnetic solar material—called the solar wind—that fills the inner solar system, reaching far past the orbit of Neptune. This solar wind creates a bubble, some 23 billion miles across, called the heliosphere. Our entire solar system, including the heliosphere, moves through interstellar space.

The prevalent picture of the heliosphere was one of comet-shaped structure, with a rounded head and an extended tail.

Despite Saturday’s so-called “March for Science,” the almost simultaneous release of a Second Edition of a Research Report showing the exact opposite of what some of the marchers claim to be the conclusions of climate science, has brought home the Orwellian reality that the marchers have gotten their claims concerning what the science says exactly backwards, as Alan Carlin explains.

The Climate March website says their forces of “The Resistance” won’t tolerate institutions that try to “skew, ignore, misuse or interfere with science.”

If the marchers really support science, they should be supporting climate skeptics, not the climate alarmists. How Orwellian can you get? The science is clear.

Carving at Göbekli Tepe

The alleged event appears to pre-date the Göbekli Tepe site itself by at least 1,500 years, which seems at odds with the idea that the carvings were intended as observations of it.

Ancient stone carvings confirm that a comet struck the Earth around 11,000BC, a devastating event which wiped out woolly mammoths and sparked the rise of civilisations, says the Daily Telegraph.

Experts at the University of Edinburgh analysed mysterious symbols carved onto stone pillars at Göbekli Tepe in southern Turkey, to find out if they could be linked to constellations. The markings suggest that a swarm of comet fragments hit Earth at the exact same time that a mini-ice age struck, changing the entire course of human history. 

Scientists have speculated for decades that a comet could be behind the sudden fall in temperature during a period known as the Younger Dryas.
