Saturn’s rings will disappear by 2025: But Why?
According to NASA’s predictions, Saturn’s rings will not be visible from Earth in 2025 due to the planet’s tilt. However, this will only be temporary.
We all know Saturn, the second largest planet in the solar system, for its iconic rings. These rings can be seen from Earth through telescopes. However, recent revelations suggest that they will soon disappear.
According to NASA, Saturn’s rings will not be visible from Earth in 2025. Of course, they won’t really disappear. We won’t be able to see the rings because of Saturn’s inclination.
Saturn’s rings will disappear in March 2025 and will be visible again in the following years
According to scientists, the rings will no longer be visible from our planet exactly 18 months from now. Right now, Saturn and Earth are not exactly aligned and the gas giant is tilted at a 9-degree angle. Next year, this will drop to 3.7 degrees, making the rings even harder to see. By 2025, they will drop to zero and will be completely invisible.
But there’s no need to worry. Saturn’s rings will temporarily disappear. Then they will gradually become visible again, reaching their maximum inclination of 27 degrees in 2032, 8 years after they disappeared. This is when we will see the best view of the rings.
Saturn’s rings are made up of comets, asteroids and other material. According to NASA data, the rings can extend up to 282 thousand kilometers from the planet. Their vertical length is around 10 meters, which means they are quite small. Finally, it should be noted that the rings were first observed by Galileo Galilei in 1610.

What Happens If the Umbilical Cord Isn’t Cut After Birth? It’s Actually Practiced in Some Cultures!
Whether you have given birth or not, everyone knows that the umbilical cord is cut some time after the baby is born. While there are debates about how many minutes after birth it should be cut, there is another situation beyond that. The umbilical cord should not be cut at all. But isn’t this harmful to the baby?
How long after birth should the umbilical cord be cut?
When it comes to the birth of a baby, there are many important decisions to make. One of these decisions is when to cut the umbilical cord. The umbilical cord is a vital lifeline that connects the baby to the placenta during pregnancy, providing it with necessary nutrients and oxygen. But how long should this connection last after birth?
Traditionally, it has been common practice to cut the umbilical cord shortly after birth, within a few minutes. This is done to prevent excessive blood loss and to make it easier to handle the baby. However, recent research and cultural practices have brought attention to the potential benefits of delaying cord clamping.
Studies have shown that delaying cord clamping for at least one minute after birth allows more blood to transfer from the placenta to the baby. This additional blood contains a rich supply of oxygen and important stem cells that can boost the baby’s immune system and improve overall health. Some studies even suggest waiting for up to five minutes before clamping the cord to maximize these benefits.
Let’s get to our main topic. So what happens if this umbilical cord is never cut?
The umbilical cord is a vital connection between the baby and the placenta during pregnancy. It serves as a lifeline, providing essential nutrients and oxygen to the developing fetus. Generally, the umbilical cord is cut shortly after birth, once the baby starts to breathe on their own. However, in some cultural practices, such as lotus birth, the cord is left intact until it naturally falls off.
Nowadays, there are many countries that have adopted the lotus birth culture. This practice involves leaving the umbilical cord attached to the baby until it naturally separates from the belly button, usually within 3 to 10 days after birth. The cord is not clamped or cut, and the newborn remains connected to the placenta during this time.
Nowadays, there are many countries that have adopted the lotus birth culture.
Nowadays, there are many countries that have adopted the lotus birth culture. Lotus birth is a practice where the umbilical cord is not cut immediately after birth, but rather left attached until it naturally falls off, usually within 3 to 10 days. This cultural practice is believed to have originated in Ancient Egypt and has gained popularity in recent years.
One of the reasons why lotus birth is preferred by some families is the belief that it provides a gentle transition for the newborn from the womb to the outside world. Supporters of lotus birth argue that cutting the umbilical cord immediately after birth disrupts the flow of blood and vital nutrients from the placenta to the baby, potentially causing stress or trauma.
However, it is important to note that the scientific evidence supporting the benefits of lotus birth is limited. Some studies have suggested that delayed cord clamping, where the cord is not cut for at least one minute after birth, can have positive effects on the newborn, such as increased iron stores and improved circulation. However, these studies did not specifically focus on lotus birth.
South Africa’s human tissue law forces births to take place at home.
South Africa’s human tissue law forces births to take place at home. This law, implemented in 2003, aims to regulate the collection, storage, and use of human tissue in the country. Under this law, it is mandatory for all births to take place at home unless there are medical complications that necessitate hospitalization. This has sparked various debates and discussions on the implications of such a law on maternal and infant health, as well as the cultural practices surrounding birth in South Africa.
Many argue that the law infringes on the rights of women to make informed decisions about their birthing preferences. Traditionally, South African women have had the freedom to choose between giving birth at home or in a hospital. This cultural practice allowed for the incorporation of traditional rituals and customs into the birthing process, which held significant cultural and spiritual importance for many communities. However, the introduction of the human tissue law has limited these choices and forced women to give birth at home, often without the necessary medical support and facilities.
For those who support the human tissue law, it is seen as a necessary measure to regulate the collection of human tissue and prevent illegal practices such as organ trafficking. The law ensures that all births are recorded and the umbilical cord and other tissues are appropriately stored for medical research or transplantation purposes. However, critics argue that the law fails to consider the diverse cultural practices and beliefs surrounding birth, making it an infringement on cultural rights and traditions.

In conclusion, South Africa’s human tissue law, which forces births to take place at home, has sparked debates regarding women’s rights, cultural practices, and the regulation of human tissue collection. While the law aims to prevent illegal practices and ensure proper documentation, it also limits birthing choices and excludes traditional rituals. It is important to consider the cultural significance of birth and find a balance between regulation and respecting the diverse beliefs and practices of South African communities.
So why is lotus birth preferred? What are the believed benefits?
Lotus birth, also known as umbilical non-severance, is a cultural practice in which the umbilical cord is not cut immediately after birth. Instead, the newborn remains attached to the placenta until the cord naturally detaches from the baby’s belly button. This practice is gaining popularity in certain communities and is believed to have numerous benefits for the baby and the mother.
One of the main reasons why lotus birth is preferred is because it allows for a gradual and gentle separation between the baby and the placenta. Advocates of lotus birth believe that this slow separation process helps in the bonding between the newborn and the placenta. It is believed that the placenta acts as a bridge between the baby and the mother, providing nourishment, oxygen, and other essential substances for the initial days of life.
Furthermore, lotus birth is believed to have a positive impact on the baby’s immune system. The placenta contains a rich supply of stem cells and immunoglobulins, which are vital for the development and maintenance of a strong immune system. By allowing the baby to remain connected to the placenta, it is believed that the baby receives an additional boost to their immune system, potentially reducing the risk of certain infections and diseases.
- Lotus birth also promotes a more natural and gentle birth experience for both the baby and the mother. It is seen as a way to honor and respect the natural process of birth, allowing the baby to fully integrate into the world at their own pace. The gradual separation of the umbilical cord is seen as a continuation of the mother-baby connection that was established during pregnancy.
In conclusion, lotus birth is preferred by some individuals due to its believed benefits for the baby and the mother. It allows for a gradual separation between the baby and the placenta, promotes a stronger immune system, and fosters a more natural and gentle birth experience. However, it is important to note that lotus birth is a personal choice and may not be suitable for everyone. Cultural practices and beliefs vary, and it is essential to consider individual circumstances and consult with healthcare professionals before making decisions regarding birth practices.
Moving on to the harms, of course we encounter serious reactions.
Moving on to the harms, of course we encounter serious reactions. When it comes to cutting the umbilical cord, it is recommended to do so within a few minutes after birth. Delaying the cutting of the cord can lead to various complications and adverse effects. The umbilical cord provides the baby with oxygen and nutrients during pregnancy, but once the baby is born, it is no longer needed. Leaving the cord attached for too long can increase the risk of infection as it is a potential entry point for bacteria.
Additionally, delaying the cord cutting can result in excessive bleeding for the mother. The umbilical cord contains blood vessels that supply oxygenated blood from the placenta to the baby. Once the cord is cut, these blood vessels should close off and stop bleeding. However, if the cord is left uncut for an extended period, the blood vessels may remain open, leading to excessive bleeding and potential complications for the mother.
In some cases, delayed cord cutting can also increase the risk of jaundice in newborns. Jaundice is a condition that causes yellowing of the skin and eyes due to an excess of bilirubin in the blood. Normally, the liver processes bilirubin and eliminates it from the body. However, when the cord is not cut promptly, there is a higher chance of an excess buildup of bilirubin, leading to jaundice.
| Potential Harms of Delayed Cord Cutting: | |
|---|---|
| Infection: | Leaving the cord attached for too long increases the risk of infection. |
| Excessive Bleeding: | Delayed cord cutting can result in excessive bleeding for the mother. |
| Jaundice: | There is a higher risk of jaundice in newborns when the cord is not cut promptly. |
Considering these potential harms, it is important for healthcare professionals to educate parents about the risks and benefits of delayed cord cutting. While there may be certain cultural practices or beliefs associated with delayed cord cutting, it is crucial to prioritize the health and well-being of both the mother and the baby. Careful consideration should be given to the timing of umbilical cord cutting to minimize the occurrence of adverse reactions and ensure a safe birth experience.
How do those who give birth in lotus care for the umbilical cord to prevent these problems from occurring?
When it comes to giving birth, there are various cultural practices that differ from one region to another. One such practice is known as lotus birth, which involves leaving the umbilical cord intact after birth until it naturally separates from the baby. This practice is believed to have several benefits, but it also comes with potential risks and complications. In order to prevent these problems, those who choose lotus birth follow specific care guidelines for the umbilical cord.
Lotus birth is preferred by some individuals and communities because it is believed to allow a gentle transition from the womb to the outside world for the newborn. The intact umbilical cord is seen as a channel that continues to provide nourishment and support to the baby during the initial days. The belief is that this helps the baby to adapt gradually to the new environment. Additionally, proponents of lotus birth claim that it fosters a strong bond between the mother and child through the necessary care and attention given to the umbilical cord.
However, it’s essential to consider the potential harms and risks associated with lotus birth. The most common problem encountered is infection. The umbilical cord, if not properly cared for, can become a breeding ground for bacteria. This can lead to serious infections, such as omphalitis, which may require medical intervention. Other complications that can arise include delayed healing, excessive bleeding, and malodorous discharge.
| Potential Problems with Lotus Birth | Care Guidelines to Prevent |
|---|---|
| Infection | 1. Keeping the cord dry and clean2. Applying natural antiseptics like salt or essential oils3. Avoiding submersion of the cord in water during baths |
| Delayed healing | 1. Ensuring proper ventilation and airflow around the cord2. Avoiding tight clothing that may rub against the cord |
| Excessive bleeding | 1. Monitoring for signs of bleeding2. Seeking medical assistance if bleeding persists or worsens |
| Malodorous discharge | 1. Maintaining cleanliness and hygiene around the cord2. Consulting a healthcare professional if foul odor persists or is accompanied by other symptoms |
If a family decides to have a lotus birth, it is crucial to follow these care guidelines to prevent potential problems. Regular monitoring, adequate hygiene, and seeking medical assistance when necessary are vital for maintaining the health and well-being of both the baby and the mother. It’s important to remember that while lotus birth is a personal choice, the safety and health of the newborn should always be the top priority.
If the family decides to have a lotus birth…
If the family decides to have a lotus birth, they are choosing to keep the baby connected to the placenta until the umbilical cord naturally detaches from the baby’s belly button. This practice, which has become increasingly popular in recent years, involves not cutting the umbilical cord immediately after birth, as is typically done in most cultures. Instead, the placenta and the baby are kept together until the cord naturally falls off.
One of the main reasons why some families choose to have a lotus birth is because they believe it allows for a more gentle and gradual separation between the baby and the placenta. They argue that cutting the umbilical cord too soon can be distressing for the baby and disrupt the natural process of transition from the placenta to independent life. By allowing the cord to detach naturally, it is believed to promote a smoother transition and potentially have long-term health benefits for the baby.
However, it is important to note that there is limited scientific evidence to support the benefits claimed by supporters of lotus birth. The practice is considered controversial within the medical community, as it may pose certain risks. Keeping the placenta attached to the baby for an extended period of time increases the risk of infection, as the placenta is essentially a decaying organ. Additionally, the prolonged presence of the umbilical cord may make it more difficult to care for the baby and can cause inconvenience for the parents.
