Sirius, the brightest star in the night sky, shines brilliantly even from a staggering distance of 56 trillion miles away. Through a telescope, its brilliance becomes even more mesmerizing, revealing its prominence in the vast cosmic expanse."

Every year, #Earth is hit by about 6100 meteors large enough to reach the surface, or about 17 every day,
research has revealed.The vast majority fall unnoticed, in uninhabited areas. But several times a year, a few land in places that catch more attention.

Star color is a function of surface temperature. If we can heat an object more, we can see that its color gradually turns blue. When we burn a wood, the fire burning next to the wood is blue. As the burning fire moves away from its source, it shifts from blue to red as the particles that make up the flame cool.
.
We can also observe this when we light a lighter or a match. For example, when a match is lit, the fire is blue when it is closest to its source. However, as it moves away from its source and encounters the relatively low temperature in the air, it gradually loses its temperature, turns from blue to white, from white to yellow, and from yellow to red, and disappears.
.
The light of hot stars is blue, and that of cold stars is red. The color of the star is determined by the amount of nuclear reaction in the core region. Since this reaction is too much in big and hot stars, the star heats up proportionally and its color changes from red to blue (respectively, red, yellow, white, blue)

This looks like a very rare ball lightning🤯 Have you ever seen something like this before?
Before beginning the explanation, we don't claim whether this video is real or not since this phenomenon is extremely rare. We don't have enough resources to validate this as real. However, if it's real, it's worth sharing with all of you.
Leg's Begin.
Ball lightning is a rare and unexplained phenomenon described as luminescent, spherical objects that vary from pea-sized to several meters in diameter. Though usually associated with thunderstorms, the observed phenomenon is reported to last considerably longer than the split-second flash of a lightning bolt and is a phenomenon distinct from St. Elmo's fire.
Some 19th-century reports describe balls that eventually explode and leave behind an odor of sulfur. Descriptions of ball lightning appear in a variety of accounts over the centuries and have received attention from scientists. An optical spectrum of what appears to have been a ball lightning event was published in January 2014 and included a video at high frame rate. Laboratory experiments have produced effects that are visually similar to reports of ball lightning, but how these relate to the supposed phenomenon remains unclear.
Scientists have proposed a number of hypotheses to explain reports of ball lightning over the centuries, but scientific data on ball lightning remains scarce. The presumption of its existence has depended on reported public sightings, which have produced inconsistent findings. Owing to the lack of reproducible data, the existence of ball lightning as a distinct physical phenomenon remains unproven.

Witness the magic of our Moon as it reflects sunlight! 🌕✨
The rocky surface of the Moon bounces light back to Earth, creating that beautiful glow we see every night. While some sunlight is absorbed, much of it is reflected, letting us enjoy the Moon's brilliance even when it's not directly lit by the Sun.
