"It was four o'clock according to my guess,
Since eleven feet, a little more or less,
my shadow at the time did fall,
Considering that I myself am six feet tall."

Larkin and Russo have fun with seeing what the continents used to look like in this interactive display. Smithsonian National Museum of Natural History - David H. Koch Hall of Fossils. (2/8/2020)
Tasmania's oldest rocks seem to have been laid down when the now-western part of the island was attached to present-day western North America.
Analysis of monazite and zircon in rocks of the ancient Rocky Cape Group in north-west Tasmania found that they are between 1.45 billion and 1.33 billion years old. These minerals, strongly resemble those found in Montana, Idaho and southern British Columbia.
The outcrop on the right and some of the shingle in the foreground are from that Neoprotozeroic geologic era. The other shingle is Basalt from the Tertiary era. The battered cray-pot in the left fg from the Quaternary ;-)

near Duntulm Castle, Isle of Skye. These were only recently discovered (2015). I had downloaded a scientific article from a journal which gave details on how to find these tracks. When we were there we saw a man and his son and mentioned to them about the tracks and the man said "I know, I discovered them...". Turns out he was one of the authors of the article I had with me. (I think he was pleased I had used the article to find the footprints). He took the time to show me some other less obvious footprints and said that these tracks in the photo were made by a long-necked sauropod (as big as a double decker bus) about 65 million years ago when Skye was located in a tropical lagoon. It was a strange feeling to stand on this exact spot and think that all those years ago this huge animal stood here and walked off towards the horizon.

Today we have been setting some natural history context for the story of "The First Tasmanians". This is a permanent exhibition at the QVMAG in Launceston. An exhibition curated by the museum and art gallery in conjunction with the Aboriginal community.
www.qvmag.tas.gov.au/Exhibitions/Permanent/The-First-Tasm...
Over the next two days we'll look at some of the specific cultural aspects.
The little machine pictured above allows the viewer to watch a simulation of how the landscape of Tasmania has changed over the last 50,000 years - not long before the first people arrived. This is deep time, prehistory, before we even begin to have oral history.
[Enlarge the photograph and you should be able to read the display.]

The formation of stars and the chaotic environments they inhabit is one of the most well-studied, but also mystery-shrouded, areas of cosmic investigation. The intricacies of these processes are now being unveiled like never before by NASA’s James Webb Space Telescope.
Two new images from Webb’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) showcase star-forming region NGC 604, located in the Triangulum galaxy (M33), 2.73 million light-years away from Earth. In these images, cavernous bubbles and stretched-out filaments of gas etch a more detailed and complete tapestry of star birth than seen in the past.
Sheltered among NGC 604’s dusty envelopes of gas are more than 200 of the hottest, most massive kinds of stars, all in the early stages of their lives. These types of stars are B-types and O-types, the latter of which can be more than 100 times the mass of our own Sun. It’s quite rare to find this concentration of them in the nearby universe. In fact, there’s no similar region within our own Milky Way galaxy.
This concentration of massive stars, combined with its relatively close distance, means NGC 604 gives astronomers an opportunity to study these objects at a fascinating time early in their life.

The muted red tones of the globular cluster Liller 1 are partially obscured in this image by a dense scattering of piercingly blue stars. In fact, it is thanks to Hubble’s Wide Field Camera 3 (WFC3) that we are able to see Liller 1 so clearly in this image, because the WFC3 is sensitive to wavelengths of light that the human eye cannot detect. Liller 1 is only 30 000 light-years from Earth — relatively neighbourly in astronomical terms — but it lies within the Milky Way’s ‘bulge’, the dense and dusty region at our galaxy’s centre. Because of that, Liller 1 is heavily obscured from view by interstellar dust, which scatters visible light (particularly blue light) very effectively. Fortunately, some infrared and red visible light are able to pass through these dusty regions. WFC3 is sensitive to both visible and near-infrared (infrared that is close to the visible) wavelengths, allowing us to see through the obscuring clouds of dust, and providing this spectacular view of Liller 1.
Liller 1 is a particularly interesting globular cluster, because unlike most of its kind, it contains a mix of very young and very old stars. Globular clusters typically house only old stars, some nearly as old as the Universe itself. Liller1 instead contains at least two distinct stellar populations with remarkably different ages: the oldest one is 12 billion years old and the youngest component is just 1-2 billion years old. This led astronomers to conclude that this stellar system was able to form stars over an extraordinary long period of time.
This image of massive galaxy cluster MACS J0416.1-2403 was part of the Hubble Space Telescope's Frontier Fields project, which combined the power of natural "gravitational lenses" in space with Hubble's ability to create long-exposure deep field images. Gravitational lenses occur when the immense gravity of massive galaxy clusters magnifies and distorts the light from objects behind them. This makes it possible to see objects far beyond the reach of normal telescopes. In this case, joint observations of this cluster by Hubble and the Spitzer Space Telescope revealed an extremely distant galaxy that would have existed about 400 million years after the Big Bang. Astronomers nicknamed the galaxy Tayna, which means "first-born" in Aymara, a language spoken in the Andes and Altiplano regions of South America. Tayna represents a smaller, fainter class of newly forming galaxies that had previously evaded detection, and which were thought to be more representative of the early universe, offering new insight on the formation and evolution of the first galaxies. MACS J0416.1-2403, is located in the constellation Eridanus.

NGC 346, shown here in this image from NASA’s James Webb Space Telescope Near-Infrared Camera (NIRCam), is a dynamic star cluster that lies within a nebula 200,000 light years away. Webb reveals the presence of many more building blocks than previously expected, not only for stars, but also planets, in the form of clouds packed with dust and hydrogen.
The plumes and arcs of gas in this image contains two types of hydrogen. The pink gas represents energized hydrogen, which is typically as hot as around 10,000 °C (approximately 18,000 °F) or more, while the more orange gas represents dense, molecular hydrogen, which is much colder at around -200 °C (approximately -300 °F) or less, and associated dust.
The colder gas provides an excellent environment for stars to form, and, as they do, they change the environment around them. The effect of this is seen in the various ridges throughout, which are created as the light of these young stars breaks down the dense clouds. The many pillars of glowing gas show the effects of this stellar erosion throughout the region.

NASA’s James Webb Space Telescope has delivered the deepest and sharpest infrared image of the distant universe so far. Webb’s First Deep Field is galaxy cluster SMACS 0723, and it is teeming with thousands of galaxies – including the faintest objects ever observed in the infrared.
Webb’s image is approximately the size of a grain of sand held at arm’s length, a tiny sliver of the vast universe. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying more distant galaxies, including some seen when the universe was less than a billion years old. This deep field, taken by Webb’s Near-Infrared Camera (NIRCam), is a composite made from images at different wavelengths, totaling 12.5 hours – achieving depths at infrared wavelengths beyond the Hubble Space Telescope’s deepest fields, which took weeks. And this is only the beginning. Researchers will continue to use Webb to take longer exposures, revealing more of our vast universe.
This image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago, with many more galaxies in front of and behind the cluster. Much more about this cluster will be revealed as researchers begin digging into Webb’s data. This field was also imaged by Webb’s Mid-Infrared Instrument (MIRI), which observes mid-infrared light.
Webb’s NIRCam has brought distant galaxies into sharp focus – they have tiny, faint structures that have never been seen before, including star clusters and diffuse features.
Light from these galaxies took billions of years to reach us. We are looking back in time to within a billion years after the big bang when viewing the youngest galaxies in this field. The light was stretched by the expansion of the universe to infrared wavelengths that Webb was designed to observe. Researchers will soon begin to learn more about the galaxies’ masses, ages, histories, and compositions.
Other features include the prominent arcs in this field. The powerful gravitational field of a galaxy cluster can bend the light rays from more distant galaxies behind it, just as a magnifying glass bends and warps images. Stars are also captured with prominent diffraction spikes, as they appear brighter at shorter wavelengths.
Webb’s MIRI image offers a kaleidoscope of colors and highlights where the dust is – a major ingredient for star formation, and ultimately life itself. Blue galaxies contain stars, but very little dust. The red objects in this field are enshrouded in thick layers of dust. Green galaxies are populated with hydrocarbons and other chemical compounds. Researchers will be able to use data like these to understand how galaxies form, grow, and merge with each other, and in some cases why they stop forming stars altogether.
In addition to taking images, two of Webb’s instruments also obtained spectra – data that reveal objects’ physical and chemical properties that will help researchers identify many more details about distant galaxies in this field. Webb’s Near Infrared Spectrograph (NIRSpec) microshutter array observed 48 individual galaxies at the same time – a new technology used for the first time in space – returning a full suite of details about each. The data revealed light from one galaxy that traveled for 13.1 billion years before Webb’s mirrors captured it. NIRSpec data also demonstrate how detailed galaxy spectra will be with Webb observations.
Finally, Webb’s Near-Infrared Imager and Slitless Spectrograph (NIRISS) used Wide-Field Slitless Spectroscopy to capture spectra of all the objects in the entire field of view at once. Among the results, it proves that one of the galaxies has a mirror image.
SMACS 0723 can be viewed near the constellation Volans in the southern sky.

Welcome World
This photograph of Ednburgh Castle was taken during the Deep Time light show to start to mark the begining of the 2016 Edinburgh Festival. It was hand held at a shutter speed of 4sec, which even image stabilisation isn't going to keep steady! So I just let the movement of the lights speak for itself...

The Deep Time Exhibit, on the first floor David H. Koch Hall of Fossils, allows visitors to travel through ancient ecosystems spread out across a 31,000-square-foot space to witness the evolution of life and get up close to some 700 fossil specimens.
The National Museum of Natural History (NMNH), administered by the Smithsonian Institute, was established in 1910 as the United States National Museum. The building, designed in the neoclassical architectural style by Hornblower & Marshall, was the first constructed on the north side of the National Mall, along Constitution Avenue, as part of the 1901 McMillan Commission plan. The museum's collections total over 500 million specimens of plants, animals, fossils, minerals, rocks, meteorites, and human cultural artifacts. With 7.1 million visitors in 2016, it is the most visited of all of the Smithsonian museums and is also home to about 185 professional natural history scientists — the largest group of scientists dedicated to the study of natural and cultural history in the world.
The Smithsonian Institution, an educational and research institute and associated museum complex, administered and funded by the government of the United States and by funds from its endowment, contributions, and profits from its shops and its magazines, was established in 1846. Although concentrated in Washington DC, its collection of over 136 million items is spread through 19 museums, a zoo, and nine research centers from New York to Panama.
Deep time. Oldest rock. Fist-sized sample from the Acasta River, an obscure little drainage up near Great Bear Lake, Northwest Territories, Canada. Self-collected from what is the oldest known in-situ (still in one piece/place/original form) rock formation on the planet, clocking in at 4.03 billion years old.
Postscript: Further age-dating measurements have pushed the Acasta River locale back to 4.2 billion years. Since I collected this sample from the 4.03 Ga site, I`ll leave it as is.

I have questions!
Questions like:
— should I be bothered that I know Grace Slick is eighty five years old?
— is it true that One pill makes you larger, And one pill makes you small, And the ones that mother gives you, Don't do anything at all, and what does this say about mother?
— why was the eponymous novel on my reading list?
— what is she looking at?
— do the digital imaging devices in mobile phones and mistaken for cameras have to be a bit rubbish at some things when they are good at others?
— why does Professor Alice ask her questions differently and how is she going to get out of her 13.8 billion year monologue without it just fizzling out?
No. Motherhood; there's a tough gig. It was supposed to help me understand the teenage psyche; whatever. Perhaps she thinks she knows me. Hmm, like taking a knife to a gunfight. Nature is unguided; why should Alice get off lightly?
I'm rarely tempted into the Big Smoke after dark — all raucous mating rituals, bad music, vomit on the pavement, that sort of thing. At least when I was younger the music was good! But coming out for Alice? That's another question.
Always inclined to learn something new every day, I thought to try the little "button" marked "x0.6" — wide angle, they say. So I pushed that button. Frankly, it's a bit rubbish. There's an excuse — I think "they" say it's a "design feature" — that it combines a low res wider image with the better bit in the middle. Once I had one of these devices with an optical zoom lens. Now, we get digital mumbo jumbo. It disappoints so much that maybe I'll never push that button again!
Yes, I did answer a question with a question! Over a couple of well-presented hours of events from deep time to just yesterday Professor Roberts logically lead from this to that. Like history itself, her story simply followed the footprints in the sand. That's all good. But every story needs an ending. Hers? Just make some time and space for Nature, and be kind to each other.
