Blood moon

Tonight there is a full lunar eclipse which is when the Earth comes between the Sun and the Moon and the earth casts its shadow on the moon.

As it progresses first there is shadow on one side of the moon. Gradually. Like a solar eclipse the curve of the Earth cuts into the Moon. As it progresses the white light from the sun is cut out by Earth’s shadow until only red light passes through Earth’s atmosphere and the Moon turns orangey red. Then the Moon starts to pull out of the shadow and gradually returns to normal

Tonight the moon is at its closest approach to earth so it is known as a super moon.

As a matter of interest I decided to try and draw what a flat earth would look like…. It would cast a flat shadow.. When it was fully eclipsed the moon would appear to be cut in half. Possibly by a red line? Other effects of a flat earth would be daylight all over the upper side then darkness all over the upper side as we tumbled through space. Also what is on the underside and is there a Trumpesque wall round the edge to keep the water in? I recently read an article about gravity. On a flat earth the people on the edge would be lying down as the gravity would be pulling everyone towards the centre of the disc……

Anyway enough rambling

The astronomy bug has truly bit, and painting pictures like this get my mind working. As I paint I feel happy and enthralled  It is like a drug to me. I get my fix out of painting. I can’t describe how I feel. Is it that thing called “flow”? The world goes on and I lose track of time.

Something pushes me to try harder to create or copy an image. The challenge of seeing it and trying to relay it on the canvas or computer. Some people can create photorealism. I’m not that good.. But I try.

I can’t sleep….

I can’t sleep, so I’m watching the cat dreaming.

I can’t sleep, so I watch its little paws.

I can’t sleep, even though the stars are gleaming,

I can’t sleep, despite long, deep, yawns…..

 

My hands are itching from an eczema flare up,

My hands are itching, the skin it seems to burn,

My hands are itching, and painfully I sit up.

My hands are itching, the clocks hands slowly turn…..

 

My mind is racing, swirling with tired thoughts,

My mind is racing, trying to find rest,

My mind is racing, while dreams are what I’ve sought,

My mind is racing, a deep sleep would be best.

 

The cat is waking, a gentle mewing breathing

The cat is waking, and wants to play a while,

The cat is waking, while I at last am sleeping,

The cat is waking, in dreams it ran so wild.

 

Well that’s the best I can do at 3.18am! I went to bed but got up again, I don’t know what started it but eczema that I have had on one finger of one hand for many years has flared up and spread. So much so that I went out and bought SLS free soap and shampoo yesterday. It stands for sodium laureleth sulphate and a friend reckons that it can cause eczema. However having used the magic soap it only seemed to alleviate the problem slightly.

I then compounded the problem because the shopkeeper tried to sell me some expensive moisturizing hand cream, I didn’t want a whole tube so they gave me a tiny sample in a little pot to bring home.  I duly put it on my hands before bedtime, now a few hours later my hands are very itchy. So no more posh hand cream, I think I will try and get something else. In the meantime I’ve put on a little hydrocortisone and I’m hoping it calms things down.

Sitting here at 3.26am wishing I could sleep like a cat….

Red Moon, Red Mars.

Tonight I was promised celestial beauty. An eclipse of the Moon, as Earths shadow would pass across it leaving only red light, which has a longer wavelength, to get past and paint the Moon red. Not only that butthis s was due to be the longest eclipse of this century. And to add to the excitement Mars is at its closest approach to the Earth for fifteen years. It is actually up there in the sky shining brighter than Sirius, the dog star…..

Celestial fireworks indeed…I have seen lunar eclipses before, usually as the moon is rising in the east and just around the time the Sun is setting in the west. They make the moon look round! Its strange but because of the lunar soil and dust it looks quite flat normally, but when you see it eclipsed, it looks like a Christmas bauble in the sky…

Mars is also red, and it looks even redder at the moment because it is having a world wide dust storm that obliterated any changes in tone, leaving a blank world facing us, but making it more reflective for sunlight hitting it.

So, waiting for both objects to rise,  and after several weeks of almost cloudless sky’s…A big grey cloud floated across the view, no gaps, no glimpses. No, just like previous sky watchers my plan to view the eclipse came to nothing.

Never mind, Mars won’t fade too quickly and the Moon will be eclipsed again. Meanwhile I think I will go try and find the telescope. It must be in the shed…

A carpet of dasies

White and yellow daisy type flowers remind me of sunshine. The dark leaves could be space and the greenery earth. Strange how a picture of petals and leaves make me think if the universe.

We need light to live. Heat from the sun warms us enough to keep the planet temperate. Light allows plants to photosynthise and create Oxygen. Without sunlight we would just be a lump of rock and frozen gasses in the infinity of space.

But it goes further than that…. the first chemical that was present after the big bang, was Hydrogen. Atoms of hydrogen were pulled together by gravity to form stars. Stars are nuclear reactors, the more hydrogen they gather from surrounding clouds of gas, the heavier they get. Eventually nuclear fusion begins and the stars light up. Hydrogen atoms join together and create Helium….

After a while (a few billion years) the stars will have converted most of their Hydrogen to Helium, and further pressure changes that to heavier atoms, from Carbon, upwards in increasing atomic weight. Eventually the star is a cinder of Iron.

But once a star is mainly burning Iron atoms, it needs to use more energy to turn the Iron into heavier elements than the Iron can provide. The energy from it also helps keep the layers of material in the star supported, or expanded. The pressure of radiation and photons of light hold the layers of star plasma up.

Then the star uses up all its fuel . If it is small nothing much may happen and it just burns out. But if it is large enough the pressure from radiation and light is not enough to hold up against the force of gravity which is trying to make it collapse.

The inward pull of gravity can make all the atoms collapse inwards, making a neutron star. A tiny ball of it will weigh a massive amount.

But if the old star is heavy enough it continues to collapse, then the energy created by the collapse can cause the stars outer layers to explode outwards. This may be a Nova, or Supernova. Supernovae create a flash of light that can be as bright  as a whole galaxy.

If the star was even bigger it can collapse completely and create a black hole. In that case the gravity of the black hole will not allow matter or light that comes close to it to escape. There is a complete absence of light.

Funny what thinking about daisies can do to you.

Apologies to the physicists, chemists and biologists out there for my rambling explanation. I’m short on facts and figures but I do like to think about these things.
