NASA astronomers have made a startling discovery as the team has managed to detect one of the oldest black holes with the help of the James Webb Space Telescope. The details are astonishing as the black hole might be dating back more than 13 billion years to the dawn of the universe.
The earliest black holes have major possibilities to unlock a puzzle about the amazing counterparts of the galaxies including the Milky Way, which is a billion times bigger than the mass of the sun.
Now, the latest observations reveal that the galaxy called GN-z11 has pushed the origins of this mystery of the black hole’s infancy and has suggested that these black holes are either constructed big or grow rapidly in their early phase.
Black holes are one of the universe’s most questionable and weirdest objects. They are extremely powerful and have an intense gravity with light or matter fighting hard to escape their grip.
The threshold of a black hole is traced out by its horizon, which is a no-point-of-return zone. Therefore, if anything goes beyond that boundary, it’s gone forever.

Who doesn't like a tidy room? After a busy day, it feels uncomfortable to return to a messy home. Waking up in a disorganized room in the morning can ruin your mood. So, it's important to keep your home organized. However, some people just don't feel like getting out of bed. Even after waking up, they stay in bed for a long time. They have no interest in organizing the bed.
According to some, organizing the bed in the morning has a positive effect on the mind. On the other hand, some people just don't feel like getting out of bed. Even after waking up, they stay in bed for half an hour, having no desire to make the bed organized. What's the point of tidying up the bed? After all, they'll be sleeping in the same bed again at night.
Today has been declared as the day to not make your bed, thinking of such people. You'll be surprised to know that this day was initiated by a fifth-grade student. A student named Shannon Barba wrote a letter directly to the US Congress with her request.
In the letter, Shannon wrote, "Sometimes, I feel tired of making my bed. It would be nice if there was a day when no one had to worry about making their bed. I would be grateful if you could pass a bill regarding this."
Lawmakers could not refuse this child's request.

There's No Need to Shower Every Day – Here's Why
Is washing ourselves very frequently necessary? Some experts believe that everyday showering is based more on a "social contract" than actual need.
According to most dermatologists, for most people, showering daily is not necessary and can even be considered unhealthy as it can strip away the skin's natural oils, leading to dryness and irritation; showering less frequently is generally considered healthier unless you have specific needs like heavy sweating or a skin condition that requires more frequent cleaning.
Key points to consider:
Skin health:
Frequent showering can dry out your skin, especially if you have sensitive skin, so showering less often can be better for overall skin health.
Environmental impact:
Showering less frequently conserves water, which is beneficial for the environment.
Individual needs:
People with oily skin or those who exercise heavily may need to shower more often.
5 Superfoods That Prevent Kidney Damage
As temperatures drop in winter, our bodies undergo metabolic shifts that can put extra strain on the kidneys. These vital organs work tirelessly to filter toxins and maintain fluid balance. To support kidney function and prevent damage during the colder months, incorporating kidney-friendly superfoods into your diet is essential—especially when consumed at night. Here are five powerful foods that help protect your kidneys:
1. Beetroot
Beetroot is packed with antioxidants and nitrates, which naturally lower blood pressure and improve blood flow. Its high fibre content aids digestion, detoxifies the body, and supports kidney cleansing. Add beetroot to winter salads or soups to take advantage of its circulation-boosting and detoxifying properties.
2. Sweet Potato
Sweet potatoes are rich in vitamins A and C, fibre, and potassium. These nutrients help regulate blood sugar levels and blood pressure—both crucial for maintaining healthy kidney function. Their nutrient profile makes sweet potatoes an excellent choice for stabilizing blood glucose and reducing the risk of kidney disease.
3. Spinach
Spinach Loaded with iron, magnesium, and antioxidants, spinach supports kidney health. However, due to its oxalate content, it should be consumed in moderation to avoid the risk of kidney stones. Enjoy spinach in controlled portions to benefit from its nutrient-rich profile while protecting your kidneys.
4. Garlic
Garlic is not only a flavorful addition to meals but also a powerful kidney protector. It contains allicin, an anti-inflammatory compound that helps lower blood pressure and cholesterol levels. Incorporating garlic into your diet can enhance both the taste and health benefits of your meals, providing natural kidney support.
5. Cranberries
Cranberries are well-known for preventing urinary tract infections by stopping harmful bacteria from adhering to the urinary tract, offering protection for the kidneys. Rich in antioxidants, cranberries help combat oxidative stress and prevent kidney damage. Drinking cranberry juice or adding fruit to your diet is a delicious and effective way to support kidney health.
Including these superfoods in your winter diet can help protect your kidneys, reduce inflammation, and promote overall well-being.
