Great song though! 8)

Blackmore's solo was the first time I ever heard the Phrygian Dominant mode of the Harmonic Minor scale in a solo and it was mesmerising. :shock: 8)

So many of the neo classical shredders in the 80s owe everything to that solo.

You definitely shouldn't panic but there is a biggish asteroid about to pass by Earth in the coming hours.

About the size of a bus, the space rock, known as 2023 BU, will whip over the southern tip of South America just after midnight GMT.

With a closest expected approach of 3,600km (2,200 miles), it counts as a close shave.

And it illustrates how there are still asteroids of significant size lurking near Earth that remain to be detected.

This one was only picked up last weekend by amateur astronomer Gennadiy Borisov, who operates from Nauchnyi in Crimea, the peninsula that Russia seized from Ukraine in 2014.

Follow up observations have refined what we know about 2023 BU's size and, crucially, its orbit.

That's how astronomers can be so confident it will miss the planet, even though it will come inside the arc occupied by the world's telecommunications satellites, which sit 36,000km (22,000 miles) above us.

The chances of hitting a satellite are very, very small.

The time of lowest altitude is calculated to be 19.27 EST on Thursday; 00:27 GMT on Friday.

Must admit this does look amazing..... I often go for week-end hikes & walks in the Welsh Mountains etc but I have yet to witness a Cloud Inversion:

https://www.bbc.co.uk/news/uk-england-d ... e-64416661

A dramatic weather phenomenon attracted a crowd of about 100 people in freezing conditions to one of of the most famous spots in the Peak District.

Danny Shepherd, who took a stunning drone shot, said temperatures fell to about 0C (32F) on Mam Tor at sunrise on Saturday last weekend during a cloud inversion - but the cold did not put walkers off.

"You don't usually get that many people up there," said the 39-year-old from Derbyshire.

"You get more people on a Saturday but even then you're talking 20 or 30 people."

Mr Shepherd said inversions had become "quite easily predictable" when using weather apps.

Cloud inversions, also known as temperature inversions, form in valleys giving a view above the clouds.

The Met Office said they could happen all year round but were most common in winter.

From the forecast Mr Shepherd said he had known about a week in advance that cloud inversions were likely to be visible during sunrise on Saturday.

He suspected others had also seen this information and the word had spread on social media.

"Most of the people on the mountain were photographers.

"There were a lot of children there with families; that was good to see.

"I didn't mind - there was no trouble, there was no litter, there was no noise.
"Everyone was just out enjoying a nice sunrise," he said.

Mr Shepherd said it was the first cloud inversion he had photographed in the snow.

"You get a really good reflection," he said.

The photo was taken at about 07:50 GMT, about half an hour before sunrise.

He said: "The hour before the sunrise, that's the best hour because you get that 'golden-hour' light.

"I was there from about 07:00 and that was when it started to get busy."

(*) In case people don't know: A cloud inversion, or temperature inversion is when the normal temperature distribution of air – warm at the bottom, colder as you go up – becomes inverted or flipped upside down. This means you have a cold layer of air trapped at ground level, overlain by warm air. 8)

This May or May Not Be Scientific But Thought It Was An Interesting Report For Those Wishing / Trying to Lose Weight / be Healthier:

https://www.bbc.co.uk/food/articles/eating_times


Meal times and weight loss

With one in four people in the UK said to be obese, could changing our meal times be an effective way of maintaining a healthy weight? Science says yes. There have been multiple studies that explore how the timing of meals impacts how a person's weight. Those participants who ate their main meal of the day earlier, and a much smaller meal after 3pm, lost weight or maintained a lower weight more easily than those who had their largest meal later.

Scientists are still trying to establish exactly why. University of Aberdeen’s Professor Alexandra Johnstone is currently carrying out research on the link between our circadian rhythms and how we metabolise food, a field of science known as chrononutrition. In The Big Breakfast Study Johnstone and colleagues highlight the growing evidence that we’re better at metabolising food earlier in the day: “Recent studies in humans have shown that ingested calories are apparently utilised more efficiently in the morning than in the evening and this is manifested through improved weight loss.”

But even though people who eat earlier tend to be leaner, it isn't a magic solution. "Chrononutrition is an evolving and developing field of science which is beginning to show how our ancient biology is in conflict with our modern lifestyle. The mechanisms behind why time of eating may influence health are not entirely clear.”

Johnstone explains that when it comes to weight loss, what’s on the plate is still the most important thing to consider. “We need to consider the whole diet rather than single foods or meals. An occasional croissant or Danish pastry is not going to make you obese in one meal, but consuming energy dense foods along with a sedentary lifestyle, over time, will.”
Closing the "eating window"

Research carried out by Jonathan Johnston, Professor of Chronobiology and Integrative Physiology at The University of Surrey, suggests there could also be a link between weight loss and eating meals within a a smaller window of time.

Pointing out it was a pilot study, and further research and is being carried out, the study saw healthy, but slightly overweight, participants delay their first meal of the day by an hour and a half. They then ate their last meal of the day an hour and a half earlier. They were directed to eat their regular food rather than go on a diet. “People actually consumed fewer calories and had less energy intake per day when they had their restricted feeding window,” says Johnston.

Johnston doesn’t rule out that this could in part be due to metabolic changes, but adds: “The fact they consumed less, was an interesting and important result… we showed the group following restricted feeding lost some of their fat tissue.” Johnston points out though this didn’t equate to an overall loss of body weight. “Probably because fat tissues are only one proportion of our overall body weight and so the effects weren't big enough to translate to overall body size… but potentially there was a benefit to their fasting blood sugar concentration.”

Could leaving 12 hours between dinner and breakfast benefit health?


:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

If you consume your first meal of the day early, then one observational study from City University New York (CUNY) suggests there could be a link between this and lower mortality levels.

The study saw researchers assess more than 34,000 US adults over two periods, spanning three decades in total. Assessing people’s ‘clock time’, they looked to see if there was a pattern between when people consume their first meal and mortality rates – of any cause. Professor Ashima Kant, chairperson of Queens College’s Family, Nutrition, and Exercise Sciences department conducted the research.

“There is existing evidence that timing of eating may be linked to energy use and storage in the body. One of the possible explanations is due to a possible mismatch between when nutrients are consumed and the timing of release of the body’s metabolic machinery for using the nutrients,” says the expert.

Kant’s study used various markers to check for benefits and detriments to health including body weight, cholesterol and insulin in the blood. The study wasn’t looking for optimum times for eating and good health, they were looking at the opposite, “our primary outcome was risk of dying from any cause by the end of December 2015.”

So, could there be a time when eating the first meal of the day would be linked to a lower rate of mortality? “In this study, the median time of first eating episode of 7:00am in men and 7:15am in women was linked to a lower risk of dying after a median of eight years of follow-up,” says Kant.

However, the expert isn’t willing to jump to conclusions about why eating later could be detrimental to mortality, explaining it “may not coincide with the time of release of hormones needed for metabolic utilization of nutrients. This is a possible reason, but we did not examine this issue, our study is observational.”


Change Your Mealtimes

When to have your ‘big’ meal of the day

“I think the weight of the evidence, so far, shows we should try and reduce evening intake,” says Professor Johnston. “Have your last energy intake of the day, as early as possible. That is probably the clearest message that we have.

“The reason for that is we seem to lose sensitivity to insulin as the day goes on. Decades ago, people coined the phrase ‘afternoon diabetes’. It showed people were less tolerant of sugar later in the afternoon and in the evening compared to how they were in the morning.

“Various studies have shown your internal circadian body clock is a strong regulator of your metabolism. Essentially, you process a meal much more efficiently in the morning than you do in the evening. So, if you eat a meal in the evening, you tend to get higher concentrations of sugar, and fat in the blood, and it takes longer for that to go back down to normal conditions. And so, we know that having prolonged sugar and fat in your blood is a health risk for various cardiac and metabolic diseases.

"It's not a huge leap, to show if you are habitually having a lot of energy later in the day, you're going to have a longer, elevation of sugar and fat and your blood, therefore, this could contribute to your risk for diseases.”

“The most common pattern of eating in the UK is to consume most of our daily calories in the evening – roughly 40 percent of our daily energy intake – and fewer calories in the morning,” says Professor Alexandra Johnstone, before adding: “UK current healthy eating advice is based around the long-held assumption that ‘a calorie is a calorie’ and that meal timing is inconsequential.

Johnstone concludes: “It is of course the type of foods you choose and portion sizes that have the biggest impact on your health.

But if it is the case that time of eating is linked to body weight and health, then we will be able to give better dietary advice to people not only related to nutritional content but also of time of eating.”

Comet Nishimura: 'Once-in-a-lifetime' chance to see it:


Stargazing fans, it's time to get to get excited because a "once-in-a-lifetime" opportunity to see a comet shooting through space is coming up.
Comet Nishimura - or or C/2023 P1 to use its official name - will be flying past the Earth at 240,000 miles per hour early on Tuesday 12 September.
The comet takes around 437 years to do one lap of our solar system - for reference it takes Earth one year.

"To say this is a once in a lifetime opportunity to see Nishimura isn't an exaggeration." said Professor Brad Gibson, the director of the astrophysics centre at the University of Hull.

Astronomers think the comet will be visible to the naked eye, so you won't need a telescope to be able to see it.

The Birth of a Star caught by the James Webb Space Telescope...


https://www.bbc.co.uk/news/science-environment-67243772


What gets me is they give these utterly banal names / titles ( HH212 ) :roll: to these amazing and miraculous events etc... Surely they should hand the naming of such things over to current great writers or poets....


Imagine you could go back in time 4.6 billion years and take a picture of our Sun just as it was being born. What would it look like?
Well, you can get a clue from this glorious new image acquired by the James Webb Space Telescope (JWST).
Towards the centre of this object, called HH212, is a star coming into existence that is probably no more than 50,000 years old.
The scene would have looked much the same when our Sun was a similar age.
You can't actually see the glow from the protostar itself because it's hidden within a dense, spinning disc of gas and dust.
All you get are the pinky-red jets that it's shooting out in polar opposite directions.

To me it looks like an Umbilical Cord of light!
