What are the black spots on Venus?

Personally, I think it may be the traces left by some living organisms. Venus, with its pressure, its scorching heat, and its surface temperature, seems to be a place where life is unlikely to survive. However, according to the latest research, Venus's atmosphere may be able to accommodate microbial life, even though the Earth's surface remains completely uninhabitable.

Venus can be hell, but not always. Climate models show that there was once liquid water on the Earth's surface and a habitable climate for more than 2 billion years.

This gives enough time for life to evolve, but at some point in Earth's past we don't know the exact time and everything becomes a mess. All of Venus's water evaporates into the atmosphere due to the uncontrolled greenhouse gas effect, which in turn further exacerbates the greenhouse effect, and today, the surface temperature exceeds 450 degrees Celsius and the atmospheric pressure is 92 times higher than on Earth. If life on Venus appears in its habitable window of 2 billion years.

Then this catastrophic transformation could destroy every living thing, no matter how big or small it is. However, a new study published this week in the journal Science points to another possibility. Some of the microbes may have retreated into the clouds, where the environmental conditions are surprisingly stable and completely mild.

This study shows that we can see these surviving microbes taking on black spots in the lower clouds of Venus.

Many people say that it is not that there is life on Venus, but most of the articles have new ** that have suggested that we should look for signs of life on the roofs of the Earth. The idea that life could exist in the clouds of Venus is not new. Astronomer Carl Sagan first proposed the idea in 1967, with an article circa 1999 stating that at high altitudes, microbial life would be frozen, but not killed, and a 2004 article concluding that the chemical conditions in the Venus cloud were in the habitable range.

It may be the traces left by some living organisms, according to research, the atmosphere of Venus may be able to accommodate microbial life, Venus once had liquid water on the surface and more than 2 billion years of dependent climate, but due to the greenhouse gas effect, the water has evaporated into the atmosphere, causing the surface temperature to exceed 450 degrees Celsius. Some of the microbes may retreat into the clouds, where the environment is surprisingly stable, and the surviving microbes may have black spots under the clouds of Venus.

It could be some kind of chemical, such as sulfur dioxide, but it could also be aliens, and scientists have not yet reached out exactly what they are.

I think it may be the traces of ancient life on Venus, or the craters and rivers on Venus.

Glad to answer for you :

It is impossible for green spots to appear in the small-leaved red sandalwood bracelet, and the general color of red sandalwood is red, dark red, and black. It has nothing to do with green. So what you're talking about can't be a small leaf red sandalwood bracelet.

Hope mine is helpful to you.

First of all, we need to know what Venus is, in fact, Venus is the mineral precipitation produced by the blockage of the ducts in the tree when the tree absorbs nutrients. You can see clearly under the magnifying glass, with the pursuit of Venus by Tanyou, the ** tide of Venus rises, some black-hearted merchants inject gold dust into the eyes of the sect to pretend to be Venus, the real Venus is covered with beads, and the fake Venus is just a layer of surface scraped off with a knife, your Venus has green spots, it may be that the trees have copper elements into the duct when they grow.

My small leaf red sandalwood strings have been in the jewelry box for a summer, and pink and green stars have also appeared, I wonder if it is the cause of moisture?

Scarab, a genus of invertebrates, insecta, Coleoptera is an omnivorous pest. There are many kinds of beetles, and if you say that there are golden spots, it should be the black horse velvet beetle.

There are about 30,000 species of beetles in the world, and about 1,300 species in China. It can be found on continents other than Antarctica. Different species live in different environments, such as deserts, farmlands, forests, and grasslands.

Different regions have different types, and here are a few examples:

1.Scarab aeruginosa.

2.North Korean black beetle.

3.Hairy back beetle.

I looked at the pigmentation, it didn't hurt, it didn't itch, it didn't rise above the skin. I don't know if other parts of your body have such spots recently, if your body metabolism is not good recently, endocrine disorders, there will be spots, and there is no fixed part, it can appear in any part of the **.

Hello! If the black spots on the clothes are due to mildew stains caused by the clothes not being washed in time, the stains are not thoroughly washed, the clothes are not thoroughly dried or placed after washing, and the storage environment is damp, etc., you can refer to the following ways to clean:

1. Pure white cotton, linen, polyester clothing, you can use white clothes to remove mildew

1) Wash your clothes with laundry detergent first;

2) Add 1 bottle cap (40g) of white clothes (600g specification) to half a basin of water (about 2 liters), stir well, soak in white clothes for 30 minutes, rinse well. If there is still no stain after soaking for 2 hours, take out the clothes, add 1 cap of this product to the basin, stir well, put in the clothes and continue soaking. The cumulative soaking time should not exceed 6 hours.

Precautions: White clothing stains are suitable for white cotton, linen, polyester, polyester cotton, cotton and linen fabrics, do not use colored clothes (including white background stripes, white background checkered, white background printing), do not use silk wool spandex nylon and other non-chlorine bleaching clothes, do not directly use the original solution.

2. For white clothes of color and other materials, you can use colored clothes to remove mildew in combination with collar netting

1) Wash your clothes with laundry detergent first;

2) Pour a small amount of water (about liters) into the basin, measure the color stain of colored clothes (600g specification) bottle caps with colored clothes (600g specification), add each bottle cap (60g each) of colored clothes and collar to water, and stir well. Soak in laundry overnight and rinse well.

The amount of water should make the clothes just soaked, and the net amount of colored clothes and collars should be increased or decreased accordingly according to the amount of water. If the stain is still not removed after soaking overnight, you can continue to soak for a longer time (mildew is more difficult to remove and usually needs to be soaked for several days).

Precautions: Colored clothes are not suitable for fading clothes and dry cleaning, if you are not sure about the fabric of the clothes, you can try it in the hidden place of the clothes; And when using, avoid touching metal buttons, zippers, metal ornaments, etc. on clothing, and avoid direct sunlight.

Small dots on the grapes are caused by high concentrations of seedless or bulking agents in grapes, which some viticulture books call "fruit thorns". It is a plant hormone, and the processing time is very long (generally in full bloom or 15 days after flowering), eating it does not affect the body, and it will not be poisoned.

Grapes, a berry, one of the oldest and most widely distributed fruits in the world, have been cultivated for a long time, and their berries are mostly round or oval, and their color varies depending on the variety. Accounts for almost a quarter of the world's fruit production; It is highly nutritious and can be made into grape juice, raisins and wine.

Most likely grape anthracnose.

Grape anthracnose, also known as grape late rot, can not only harm grapes, but also damage apples, pears, peaches, dates, hawthorns, persimmons, strawberries, figs and other fruit trees, as well as some vegetables, flowers, forest trees and other plants.

1) Symptoms Grape anthracnose mainly harms fruits, and leaves, new shoots, cobbles, and tendrils occur rarely. In the early stage of the disease, black, round, and fly fecal-like spots appeared on the surface of the young fruits, but due to the high acidity and hard flesh of the young fruits, the growth of the pathogen was restricted, and the lesions did not expand, and no conidia were formed, and the diseased parts were limited to the epidermis. When the fruit begins to color, the fruit becomes soft, the sugar content increases, the acidity decreases, and it enters the peak period of disease, initially on the surface of the diseased fruit, round, slightly concave, light brown lesions, and the surface of the lesions is densely populated with small black dots (conidia disc), when the weather is humid, the conidia disc can be excluded from the crimson sticky matter (spore block), and then the diseased fruit gradually dries up, and finally becomes a stiff fruit.

Many diseased fruits do not fall off, and the whole panicle of stiff grapes is still hanging on the branches.

Pesticide residues, fly droppings, or scars of their own.

Black mold Black mold: Damage evergreen woody flowers. At first, the leaves show dark brown mold spots, and later expand to form a black soot-like mold layer, which affects the photosynthesis of flowers, weakens the growth of the plant and affects the appearance, and causes the death of the whole plant in severe cases.

Prevention and control measures mainly strengthen ventilation and light transmission, reduce indoor humidity, ** harm scale insects, aphids, eliminate the conditions for the occurrence of mold, and spray the same amount of Bordeaux liquid on the diseased plants.

It is iron oxide, which contains iron in the clay during firing, which is not removed, or caused by iron cables that fall during firing, and it is of little significance to remove, only wash with hydrofluoric acid (be careful)!
