Arab weather

Arabia Weather – Although huge mountains, vast seas, oceans and natural islands are a challenge to contain in a single glance, the vision changes completely when images of these areas are captured from elevated positions. Scenes appear as small models, and some drawings may take on a strange shape, which has been documented in numerous images from NASA.

Specialists at NASA’s Earth Observatory published several images of different areas on the surface of the planet Earth. Although the natural space is large, these areas appear very small in the photos, as if they form strange faces and shapes that arouse astonishment. In one image, the figure appears as a skull with its eyes staring directly into the camera lens, while in another image it appears as an animal jumping with grace and strength, and in a third image it appears as a human face.

The Sputnik website quoted the images published by NASA, in this way:

Volcanic caldera lake

The volcanic caldera lake appears in the image like a giant skull in the desert, with its wide eyes staring directly into the camera lens. This deep lake is 1,000 meters wide and was formed as a result of a massive volcanic eruption in the distant past. This mountainous region is located in the central desert, and the photo was taken by an astronaut. The unique shape of the lake appears as a result of previous volcanic eruptions and the accumulation of salt from hot springs.

Sao Miguel Island

São Miguel Island appeared in the image as the round face of a small animal, where two eyes, a nose and a mouth could be seen. São Miguel Island is the largest, most populous and most volcanically active of the nine islands of the Azores archipelago in the Atlantic Ocean region.

Stratosphere region

The image shows faces that appear to be chasing each other, thanks to the hobby of some NASA scientists. They search atmospheric data to find the rare moment when faces can be seen in this data, and then take pictures of them.

Weather of Arabia – The European Space Telescope “Euclid” published its first images of the universe, which showed a nebula resembling a horse’s head in a wonderful way, along with distant galaxies that had not been observed before. This image is a unique window into understanding the universe, and holds “indirect evidence” of the existence of dark matter.

The Euclid mission began in July last year and is carrying out a unique mission aimed at uncovering the mysteries of the universe, including dark matter and dark energy. The telescope prepares a map of a third of the sky, which contains two billion galaxies, to provide the most accurate three-dimensional map of the universe to date.

After the Euclid space telescope reached another telescope, the James Webb, at an observation point about 1.5 million kilometers from Earth, the European probe began sending the first results of its observation. These results were revealed on Tuesday from the European Space Operations Center in Darmstadt, Germany.

In a statement by the head of the European Space Agency, Joseph Ashbacher, he said that these amazing images, revealed by the European Space Operations Center in Darmstadt, Germany, remind us of the importance of space exploration to understand more of the secrets of the universe. One of these images was dedicated to the Horsehead Nebula within the nearby Orion constellation, in addition to images of spiral galaxies and others of an “irregular” nature.

Euclid’s first images are here

These five images illustrate Euclid’s full potential; never before has a telescope been able to create such razor-sharp images across such a large patch of the sky, and looking so far into the distant Universe.

Rene Lorig, the project’s scientific director, explained that the most “exciting” image is that of the Perseus Cluster, a distant group that includes more than a thousand galaxies. In the background were more than 100,000 additional galaxies, some ten billion light-years away, that had never been observed before.

The astronomer and physicist at the French Atomic Energy Commission, who is a member of the Euclid Alliance, explained that the unique peculiarity of this telescope lies in its ability to have a wide view “unprecedented in the history of astronomy,” allowing it to explore the early ages of the universe. He pointed out that James Webb, compared to him, appears as if he is “looking at the sky through the eye of a needle.”

Thanks to this wide view, the telescope, which is equipped with two observing devices (optical and near-infrared), can quickly capture high-resolution images. The first five images only took about eight hours.

According to the European Space Agency Euclid, this telescope is considered the “Dark Universe Detective,” as it investigates why 95 percent of the universe is made up of dark matter and dark energy, as current knowledge lacks sufficient data about these two phenomena.

Dark matter is the “glue” that prevents stars from being flung out of galaxies, and repulsive dark energy is “the driving force behind the accelerating expansion of the universe,” explains ESA Scientific Director Carol Mundell.

René Lorig noted that the first batch of Euclid images revealed “indirect evidence” of the existence of dark matter. He noted that the probe did not detect any stars tracking the globular cluster NGC 6397, which forms a cluster of stars. He added, “One theory says that it is possible that there is dark matter around us.”

The telescope is expected to release the second batch of images in January, with the European mission expected to continue until at least 2029.

Arabia Weather – NASA announced that Saturn’s rings will become invisible from Earth within less than 18 months.

This announcement came according to an article published by the British newspaper “Daily Star”, in which experts from the American Space Agency confirmed that by 2025, the rings on Saturn may become invisible from Earth.

Details of the disappearance of Saturn’s rings

Despite their enormous extension – the rings are only half a mile thick – when Saturn is tilted into alignment with stargazers on Earth, the rings will be visible at best as a thin line. As a result of this thin thickness of the rings, it will appear as if they have almost disappeared.

NASA experts expect the massive rings, which are 175,000 miles wide, to disappear relatively due to the equinox event. Although this disappearance will not be permanent, the rings will not become visible from Earth again until the next phase of Saturn’s 29-year rotation period.

Will Saturn’s rings disappear?

Saturn’s seven distinct rings are made up of ice, rocky debris and dust, meaning they could disappear entirely as a result of erosion. But scientists do not expect this to happen before about 300 million years. What is striking is that the rings can only be seen for short periods at a time before disappearing from view.

Saturn moves with a slight tilt toward and away from the Sun during its orbit, and for this reason, we can see the rings perfectly from the side about every 13.7 to 15.7 years, making them appear invisible at a distance of up to 746 million miles (1.2 billion kilometers).

Currently, Saturn’s rings are tilted towards Earth at an angle of 9 degrees, and this angle is expected to decrease to only 3.7 degrees by 2024. This phenomenon has not occurred since September 2009, the last time was in February 1996, and it is expected to happen again in October. 2038.

Arabia Weather – Researchers say that the strangely dense rocks in the inner layer are the result of a collision that occurred 4.5 billion years ago.

Many scientists believe that about 4.5 billion years ago, a Mars-sized object collided with Earth, spewing out debris that combined to form the Moon. Some remnants of this object, called Theia, still exist today in the form of large amounts of dense material located above the Earth’s core

In recent years, geophysicists have discovered continent-sized areas of rock at the bottom of the Earth’s interlayer where seismic waves travel abnormally slowly, indicating that the rocks there are denser than the rest of the layer’s rocks. One of these spots, known as large low-density provinces, lies beneath the continent of Africa, while the other lies half a world away beneath the Pacific Ocean, according to planetary geodynamicist Qian Yuan of the University of California, Technology Institute.

Some researchers have suggested that these blocks are the remains of tectonic plates that were pushed under the tectonic plates and then sank to the boundary between the Earth’s outer core and the upper layer. But Yuan and his colleagues offer a different origin story.

The Moon is only about 2% of Earth’s mass, leaving a significant amount of Theia unexplained. So, using a supercomputer simulation, the researchers tracked the effects of a collision between Earth and another object with a mass roughly 10 percent of Earth’s mass.

In the simulation, each object before impact had a dense iron core surrounded by a light rock crust. Each object was digitally divided into particles about 10 kilometers in diameter, so that fragments could be tracked after impact, explained one of the study’s authors, Vincent Eck, a computational physicist at Durham University in England. He points out that the team’s simulations tracked about 100 million particles.

Simulations suggest that a significant portion of Theia’s core — equivalent to about 3% of Earth’s current mass — was left behind on the planet. Shortly after the impact, this dense, molten material would have sank to join the Earth’s core. Meanwhile, the research suggests that a significant portion of Theia’s crust — amounting to about 5% of Earth’s mass — was embedded in the upper 1,400 kilometers or so of Earth’s surface.

Lunar rocks indicate that Theia’s crust contained higher levels of iron oxide minerals. This means it was likely a few percent denser than Earth’s interlayer, Qian says. The researchers suggest that during the few decades following the impact, this denser-than-average material slowly fell to accumulate and form large low-velocity provinces.

Although many researchers have suggested that these low-velocity provinces are remnants of tectonic plates, others have suggested that they are high-density remnants of Earth’s original magma ocean that submerged to the lowest levels of Earth’s interlayer. “Attributing it to material left behind by the collision between Theia and the emerging Earth is a new idea, apparently,” says Paul Tackley, a geodynamist at TH Zurich University, who was not part of the new study.

Whether or not a collision with Theia resulted in the low-density provinces, it is at least possible that they have been extending for approximately 4.5 billion years since the moon formed, Takeli says. If the material in these regions is dense enough to resist mixing with the overlying layer as it flows slowly through it, it can persist over geological time.

“Giant impact hypothesis”

The collision between Earth and a protoplanet, known as… “Giant Impact Hypothesis” The leading theory on how the Moon formed. Previously, researchers suggested that such a collision would help explain subtle chemical differences between Moon rocks and Earth rocks. Scientists have recently suggested that the collision between Earth and Theia, in addition to creating our Moon, also initiated the process of plate tectonics.

ArabiaWeather – Pluto is a somewhat mysterious dwarf planet. It was discovered in 1930 AD, and it was considered for a long time the ninth planet in the solar system after the planet Neptune until many planets similar to it were discovered, making it reclassified as a “dwarf planet.”

What is the planet Pluto?

Pluto is known as a dwarf planet with a somewhat complex and mysterious character. Pluto has a diverse terrain that includes mountains, valleys, plains, craters, and is even thought to contain rivers of ice. Historically, Pluto was considered the ninth planet in the solar system after Neptune. After discovering many similar and interesting objects in the Kuiper Belt region far beyond Neptune. In 2006, Pluto was classified as a dwarf planet instead of an icy planet.

When was the planet Pluto discovered? What is the reason for its name?

Planet Pluto was discovered in 1930. This icy planet was named after the Roman god of the underworld. What is striking is that Pluto is the only planet that was named by an 11-year-old girl. Venetia Burney of Oxford, England, proposed to her grandfather to name the new planet after the Roman god of the underworld. This proposal was sent to Lowell Observatory, and was chosen to become the official name of the new planet.

How big is planet Pluto? How far is it from the sun?

Pluto’s radius is about 715 miles, which is approximately 1,151 kilometers. Pluto’s width is about 1/6 the width of Earth, with Pluto’s width being about 1,400 miles or approximately 2,253 kilometers. Thanks to this small size, Pluto is roughly half the width of the United States. Pluto is about 3.7 billion miles from the Sun, which is approximately 39 astronomical units. From this far away, it takes about 5.5 hours for sunlight to get from the Sun to Pluto.

What is the shape of the orbit of the planet Pluto?

Pluto has an unusual orbit around the Sun compared to other planets. Its orbit is elliptical and inclined. One day on Pluto takes about 153 hours. Its axis of rotation is tilted at an angle of about 57 degrees relative to the plane of its orbit around the sun. This means that Pluto is rotating almost on its side. In addition, Pluto exhibits a retrograde rotation, meaning it rotates from east to west like Venus and Uranus.

How many moons does Pluto have?

Pluto has five known moons: Charon, Nix, Hydra, Kerberos, and Styx. Charon is believed to be the largest moon, and there is a belief that this Pluto lunar system may have been the result of a collision early in the history of the solar system between Pluto and another body similar in size. Pluto’s moons are named after mythological figures associated with the underworld, showing the connection between the moon names and Roman and Greek mythology.

What is Pluto’s atmosphere made of?

Pluto has a thin, fragile atmosphere. This atmosphere is characterized by expansion as Pluto approaches the Sun and collapses as it moves away from it. The atmosphere consists mainly of molecular nitrogen, but methane and carbon monoxide molecules have also been detected.

Is Pluto suitable for life?

Pluto is thought to have an average surface temperature of about -387 degrees Fahrenheit or -232 degrees Celsius. These extremely low temperatures make Pluto’s surface environment so cold that they make life as we know it on Earth impossible. Under these conditions, the water is in a solid state and resembles rocks.

However, there is a belief that Pluto’s interior is warmer and that it may contain an ocean or sea in its depths. This means that there may be an aquatic or watery environment mixed with solids deep within the dwarf planet’s interior. Although conditions on Pluto’s surface make it uninhabitable for life as we know it, it holds potential secrets about the formation of celestial bodies and the history of the solar system.

More Frequently Asked Questions Planet Pluto

Are there rings around Pluto?
There are no known rings around Pluto.

What is Pluto made of?
Pluto is mainly composed of rock and ice, with a thin layer of atmosphere surrounding it.

How long does it take for Pluto to orbit around the sun?
Pluto’s orbit around the Sun takes about 248 Earth years.

What can Pluto be classified into?
Pluto is currently classified as a dwarf planet in the solar system.

What color is the planet Pluto?
Pluto’s color is mostly gray or brown due to the presence of natural substances such as methane, as well as icing on its surface.

Why is Pluto cold?
Pluto is a cold planet; Because of its great distance from the sun, temperatures on its surface are very low, not enough to support life as we know it.

Pluto is a dwarf planet belonging to the Kuiper Belt group. Before it was classified as a dwarf planet in 2006, it was thought to be the ninth planet in the solar system. Pluto was discovered in 1930 and named after the god of the underworld in Roman mythology. It has a radius of about 1,151 kilometers and is about 3.7 billion miles from the sun. Its atmosphere is mainly composed of nitrogen and it contains five known moons, the largest of which is Charon. Due to the cold temperatures and dry conditions on its surface, it is thought to be unlikely to support life on Pluto’s surface.

Arabia Weather – Our solar system is certainly not a quiet and silent place. On the contrary, it is considered a living symphony of cosmic sounds, as our solar system consists of eight giant planets and many other celestial bodies, and therefore we can discover that there is distinct activity on both the visual and audio levels in this space. Wonderful solar system.

Do the planets have voices?

Recently, NASA’s Perseverance rover successfully landed on Mars after a nearly seven-month journey. Through it, we were able to see wonderful pictures of the charming rocky landscapes in Jezero Crater. Despite the calm that these areas appear in the first picture, the reality is quite the opposite, as NASA scientists were able to capture strange sounds made by objects in our solar system, through… Converting radio emissions into sound waves.

You can hear these wonderful sounds in the video below, including the eerie cacophony of plasma waves, the mighty bellowing of Jupiter and the stormy howls of Mars, as well as the sounds of other planets in our solar system.

It is truly amazing to discover sounds reaching us from planets located hundreds of millions of kilometers away from our small planet

If there’s a planet we know we don’t want to land on our next space adventure, it’s Venus. Venus is a very harsh environment and most of the sounds it makes are not a friendly greeting.

Right now, NASA is working hard to document more of these sounds, thanks to the contribution of the Perseverance rover, which is visiting Mars. This space adventure may reveal more planetary gas in our solar system.
