Mysteries of the Cosmic Web: Dark Matter, Gas and Galaxies

The cosmic web is a big part of how the universe is structured. It is made up of dark matter, gas, and galaxies. When we look at the universe, we see that galaxies are not just scattered randomly. They are organized in a way that scientists call the large-scale structure of the universe. The cosmic web is a key part of this structure.

In simple terms, the cosmic web is made up of three main things: dark matter, gas, and galaxies. Dark matter is the most abundant, making up about five-sixths of the cosmic web. Dark matter doesn’t interact with light, but it has a strong gravitational pull. It acts like a framework for galaxies and clusters of galaxies to form. The other part (one-sixth) of the cosmic web is made of regular matter: baryons like protons and neutrons, and electrons. This matter exists as intergalactic gas or as the stuff in galaxies, like stars, gas, and dust.

The gas in the cosmic web can be hot or cold, depending on where it is. The gas in galaxy clusters is usually very hot, reaching temperatures of tens of millions of degrees. Scientists call this intracluster gas or the intracluster medium (ICM). The ICM gives off X-rays that scientists can observe. It helps us understand how mass is spread in clusters and the history of how clusters formed. The ICM also affects how galaxies evolve in the cosmic web. It can take gas away from galaxies, stopping new stars from forming.

On the other hand, the gas in the filaments of the cosmic web, connecting galaxy clusters and superclusters, is usually colder, ranging from thousands to tens of thousands of degrees. This gas is known as the warm-hot intergalactic medium (WHIM). It’s challenging to observe the WHIM directly because it’s not as hot or dense as the gas in the ICM. The light it gives off doesn’t travel far in the universe before being absorbed. Still, scientists think the WHIM is an important part of the matter in the universe. It might also be crucial for helping galaxies grow by providing fuel for new stars to form.

Galaxies are found in clusters and superclusters, and they are part of the cosmic web. Throughout their existence, galaxies interact with the gas in the cosmic web. Gas from the web falls into galaxies, helping create new stars. At the same time, gas inside galaxies is pushed into the cosmic web by things like winds from supernovae and active supermassive black holes. These interactions could be the key to understanding how galaxies change over time.

New Study Dampens Hope for Earth-Like Planets and Extraterrestrial Life

Since 1961, scientists have used the Drake equation to estimate the number of advanced alien civilizations in the Milky Way. However, a recent study in the Monthly Notices of the Royal Astronomical Society provides less optimistic findings, focusing on the conditions necessary for photosynthesis.

The study explores the requirements for oxygenic photosynthesis, a process vital for life on Earth. Oxygenic photosynthesis occurs when species combine carbon dioxide, water, and light to produce sugar and release oxygen. The authors investigate if known exoplanets in habitable zones receive enough photosynthetically active radiation (PAR) to support life.

The results reveal challenges in finding suitable real estate in the Milky Way. Stars burning at half the sun’s heat lack the energy necessary for a thriving biosphere. Red dwarf stars, common in the galaxy, provide even less energy for photosynthesis. This poses a challenge in the search for alien life, indicating that Earth-like conditions on other planets might be less common than hoped.

While very large and bright stars can support photosynthesis, they burn out or explode before advanced life evolves. The study supports the “Rare Earth hypothesis,” suggesting that planets with the right conditions for complex life are relatively scarce in the universe.

Although the study implies a lower number of planets suitable for life, it doesn’t make the possibility impossibly small. Planets like Kepler-442b, receiving enough solar radiation, offer hope. The search for alien life will continue, but expectations should be tempered.

Biodiversity and Challenges in Caspian Sea: Close Look at Natural Marvels

The Caspian Sea is a unique place that can be called both a lake and a sea. Even though its water is salty like the ocean, it’s not as salty. It can also be considered a lake because it’s not connected to any sea or ocean. Situated between the Caucasus Mountains to the east and grasslands to the west, it covers a vast area of 371,000 square kilometers.

The Caspian Sea is shared by five countries: Kazakhstan, Russia, Azerbaijan, Iran, and Turkmenistan. About 5.5 million years ago, it completely separated into its own basin. Currently, the Caspian Sea has a salinity of 1.2 percent. The Volga River is its primary water source, and the South Caspian, with an average depth of 3,300 feet, contains 66 percent of the sea’s water. The sea’s islands are mostly close to the coast.

Many bird species use the Caspian Sea as a temporary residence, and Baku, the capital of Azerbaijan, is located near its shores. A unique species, the Caspian seal, is found only in this region. Once numbering one million, the seals have decreased to 100,000 due to human hunting. Other whale fish species that were once present in the Caspian Sea have disappeared.

Surprisingly, special species of tigers, leopards, and lions, such as the Caspian tiger and Asiatic lion, were found in the Caspian region. The Persian cheetah is also a unique inhabitant. The Caspian Sea is home to specific sturgeon fish species not found anywhere else.

Iran’s part of the Caspian Sea holds significant oil reserves, estimated at 150 billion barrels. Iran regularly imports crude oil from this region. Russia’s part of the Caspian Sea contains reserves of fuel oil and natural gas.

Unfortunately, the construction of factories around the Caspian Sea has led to the dumping of waste, resulting in the loss of marine biodiversity. In response, the five littoral countries formed an organization and hold the Caspian Conference every two years to address these environmental challenges.

Einstein’s Legacy: Dark Energy and the Expanding Universe

Only five percent of the universe is visible to the human eye, while the remaining 95 percent is composed of mysterious entities known as dark matter and dark energy. These concepts, though challenging, have led to remarkable discoveries in the realm of science.

The universe is in a constant state of motion, either expanding or contracting, as proven by Einstein. His research demonstrated that galaxies are steadily moving away from us, indicating the ongoing expansion of the universe. Intriguingly, this expansion is accelerating over time, defying the gravitational forces at play.

This phenomenon gave rise to the concepts of dark energy and dark matter. While the specifics of dark energy remain a subject of ongoing research, scientists have confirmed its existence and are exploring its impact on the universe. Dark energy constitutes a significant portion, around 70 percent, of the total mass in the universe.

In 1988, scientists formulated equations revealing an excess pressure countering gravity in the cosmos. Initially referred to as the cosmological constant, it was later identified as a component of dark energy, validating Einstein’s equations.

Einstein himself played a pivotal role in this discovery, acknowledging the contributions of scientist Hubble. Hubble’s groundbreaking work provided compelling evidence regarding the cosmos’ expansion. Though the intricacies of dark energy are not fully understood, these revelations showcase the enigmatic nature of the universe and our evolving comprehension of its fundamental forces.

The Mysterious Ababil Birds: A Tale of Migration and Sacred Beliefs

Ababil birds have always been surrounded by mystery. Some people even believe that these birds migrate to the moon during winter and take naps in the water. The holy religious book Al-Qur’an also mentions the Ababil bird, setting it apart from other bird species.

In Greek and Roman texts, a similar mysterious bird is referred to as the ababil. These birds make their nests in tree trunks or stables and have a unique love for living near wetlands. When it gets very cold, these birds leave their winter homes and embark on a long journey. The ababil bird seeks warmer regions to spend its days. Interestingly, if a bird is born in a warm region, it tends to stay there for its entire life.

In the western world, the ababil holds significance as a symbol of the arrival of spring. People observed the behavior of these birds to predict the weather. If a ababil flew close to the ground, it was believed to signal upcoming rain. On the other hand, if it soared high above the ground, good weather was anticipated.

One intriguing belief was that Ababil birds carried the souls of departed individuals. This sacred association led many to consider the ababil as a special and revered bird. During winter, spotting these birds becomes quite challenging as they tend to stay out of sight.

Researchers are currently exploring the mystery of where these birds go during the winter season. Given their fondness for living near wetlands, many novels and stories have been written about the Ababil bird. Some even claim that these birds emerge from the depths of rivers.

The unique characteristics and behaviors of Ababil birds have sparked the imagination of people throughout history. Whether it’s the belief in their migration to the moon, their association with predicting weather, or the sacred connection to departed souls, these birds continue to capture our fascination.
