The Toughest Predators Ever: Tyrannosaurus Rex.

    Tyrannosaurus Rex was one of the most ferocious creature to ever roam the Earth. With a gigantic body, keen teeth, and jaws powerful enough to smash a vehicle, this renowned carnivore controlled the forested river valleys of western North America during the late Cretaceous period, 68 million years ago.

    T. Rex is a well-known Tyrannosaur, yet our understanding of him is continually changing. Improved technologies, including as biomechanical modelling and x-ray imaging, have helped scientists obtain a better understand of how this apex predator lived.

    Tyrannosaurus rex, which means "King of the Tyrant Lizards," was designed to take control. This dinosaur's massive body covered up to 40 feet—roughly the length of a school bus—from its nose to the tip of its powerful tail. T. rex, weighing up to eight tonnes, raised headfirst across its territory with two powerful legs. These dinosaurs most likely hunted living animals and collected cadavers, and they occasionally ate one another.

    Tyrannosaurus rex had a good sense of smell, which helped it find its prey. While scientists have long known that this dinosaur's brain was dedicated to scent processing, current research has revealed that T. rex has nearly as many genes encoding its olfactory receptors as a house cat does today. This strong nostrils most likely helped T. rex find mates and identify other predators.

    The head of a Tyrannosaurus dinosaur was very terrifying. This ruthless carnivore was designed to crush through its prey, with a hard cranium that allowed it to concentrate all of its muscle power into a single bite, making a up to six tonnes of pressure. This dinosaur utilised its 60 hooked teeth, each about eight inches long, to puncture and hold flesh before throwing it into the air and eating it whole. To protect from overheating while crushing prey with its powerful jaws, the gigantic animal developed openings in its head to keep its brain cool, similar to those found in alligators.

Tyrannosaurus Rex.

    Tyrannosaurus rex, a ferocious dinosaur, had tiny arms that biologists debated. Some believe they were evolutionary leftovers or served non-predatory purposes, while others argue they were evolved for "cruel cutting" in close quarters. Considering their powerful thighs, these dinosaurs could only walk at 12 miles per hour, which scientists believe would have fractured their feet if they travelled faster.

    Tyrannosaurus rex, a dangerous predator with a life expectancy of 28 years, suffered a growth rise during its adolescent years. A 2020 analysis of Nano Tyrannus fossils found that the bones belonged to a young T. rex rather than another species. This shows that Tyrannosaurus rex's growth rate varied as it aged, and that it could slow down when food was limited. Despite its advantages, T. rex was unable to equal the 66 million-year-old catastrophe that killed three-quarters of all species on Earth. This catastrophe occurred when an asteroid or comet collided with Earth, destroying Tyrannosaurus rex and other non-avian dinosaurs and marking the end of the Cretaceous epoch. 

The Brief History of The Sun.

The Sun:

The Sun is the star at the centre of our solar system. Its gravity holds the solar system together, keeping everything from the - biggest planets to the smallest bits of debris - in its orbit.

Heat and light are produced by nuclear events that occur deep beneath. In order to produce this energy, The Sun has been using four million tonnes of hydrogen fuel each second since its formation, or around 4.6 billion years ago.

Solar Flares:

A solar flare is a massive eruption that occurs on the Sun when energy that has been trapped in "twisted" magnetic fields- which are typically found above sunspots, Chromosphere -is suddenly released.

They may heat materials to millions of degrees in a matter of minutes, resulting in a burst of radiation that includes: radio waves, X-rays, and gamma rays.

Sun Spots:

Sunspots are areas where the magnetic field is about 2,500 times stronger than Earth's, much higher than anywhere else on the Sun. Because of the strong magnetic field, the magnetic pressure increases while the surrounding atmospheric pressure decreases.

This in turn lowers the temperature relative to its surroundings because the concentrated magnetic field inhibits the flow of hot, new gas from the Sun's interior to the surface.

Sunspots tends to occur in pairs that have magnetic fields pointing in opposite directions.

Why Sun Spots are Dark?

The sunspots are large concentrations of strong magnetic field. Some energy is partially prevented from passing through the surface by this magnetic field.

As a result, sunspots experience a lower surface temperature than other areas of the surface. It appears darker when the temperature is lower.

Coronal Mass Ejections (CMEs):

Coronal mass ejections (CMEs) are large expulsions of plasma and magnetic field from the sun's atmosphere the corona.

Compared to solar flares bursts of electromagnetic radiation that travel at the speed of light, reaching Earth in just over 8 minutes.

Formation of CMEs:

The more explosive CMES generally begin when highly twisted magnetic field structures (flux ropes) contained in the Sun's lower corona become too stressed and realign into a less tense configuration - a process called magnetic reconnection.

Near Earth CMEs Effects:

Auroras:

The CMEs causes stunning light displays known as auroras, visible in the polar regions of the earth.

Geomagnetic Storms:

CMEs can cause significant disturbances in Earth's magnetosphere, leading to geomagnetic storms which are; Satellite Operations, Power Grids, Communication Systems.

Radiation Hazards:

It Increases radiation levels at high altitudes, especially near the poles.

Preventing & Monitoring:

SPACE WEATHER FORECASTING:

To provide early alerts of possible CMEs, organisations such as NASA and NOAA's Space Weather Prediction Centre (SWPC) track solar activity.

AID:

Continuous monitoring and improved prediction models are essential to prevent the bad impacts of CMEs.

How to Find the Sun Spots Area:

To find the area of sunspots, I use the manual formula to calculate the area of the sunspots.

As = ((Af x n) / cos (B) x cos (L))

Where,

As - Area of the sunspot,

Af - Area factor constant for the solar chart image (i.e., 63.66),

n - Number of grid sares occupying the sunspot,

B- Heliographic latitude,

L - Angular distance of the sunspot from the solar disk centre.

The physical unit for the calculated area is a millionth of a hemisphere (MHS). 

Solar Cycle:

About every 11 years, the Sun's magnetic field gradually changes polarity, a process known as the solar cycle. This reversal causes changes in solar activity.

The solar cycle has been observed and recorded since the mid-18th century, with the current cycle being Solar Cycle 25.
