This Is Not a Comet, outer space, space videos
Outer Space - It Is Mercury's Tail Made Out of Sodium. Almost like a big ol' comet, tail streaming millions of kilometres away from the planet, glowing with faint orange-yellow light.
It's all thanks to the planet's position: Mercury is the innermost planet in our Solar System. It's less than half the distance from our star than Earth, an average distance of 58 million kilometres (36 million miles).
At that distance, the small, dense, rocky world is constantly bathed in solar radiation and buffeted by solar wind

Pluto and charon
Pluto and Charon are two celestial bodies in our solar system, and they share a unique and intriguing relationship. While Pluto was once considered the ninth planet in our solar system, it was reclassified as a dwarf planet in 2006 by the International Astronomical Union (IAU). Pluto is located in the Kuiper Belt, a region beyond Neptune filled with icy objects. It has a relatively small diameter of about 1,473 miles (2,377 kilometers), making it smaller than Earth's moon. Pluto's thin atmosphere is primarily composed of nitrogen, and its surface is covered in a mix of frozen ices, including nitrogen, methane, and carbon monoxide. Pluto follows a highly elliptical orbit, causing it to sometimes come closer to the Sun than Neptune.
Charon, on the other hand, is Pluto's largest moon and is often considered more of a binary companion due to its significant size compared to Pluto. Discovered in 1978, Charon boasts a diameter of about 751 miles (1,212 kilometers), which is roughly half the size of

Nearby Spiral Galaxy NGC 4945,size of a spiral galaxy?
Outer Space - NGC 4945 (also known as Caldwell 83) is a barred spiral galaxy in the constellation Centaurus, visible near the star Xi Centauri. The galaxy was discovered by James Dunlop in 1826 and is thought to be similar to the Milky Way Galaxy, although X-ray observations show that NGC 4945 has an unusual energetic Seyfert 2 nucleus that might house a supermassive black hole.
NGC 4945 one of the brightest galaxies of the Centaurus A/M83 Group, a large, nearby group of galaxies. The galaxy is the second brightest galaxy in the subgroup centered on Centaurus A.

Milky Way Galaxy Collision with Andromeda
Outer Space - The Andromeda-Milky Way Collision is a galactic collision that is expected to occur in 4 billion years between the two largest galaxies in the Local Group-the Milky Way and the Andromeda Galaxy but where the stars involved are separated by a large enough distance to make it impossible for any stars to collide.
What will happen if the Milky Way collides with the Andromeda galaxy? Did Andromeda and Milky Way collide? Will Earth be destroyed when the Milky Way and Andromeda collide?

Galaksi Pusaran (Whirlpool Galaxy) from Hubble Space Telescope
Outer Space - The Whirlpool Galaxy (also known as Messier 51a, M51a, or NGC 5194) is a primary design spiral galaxy interaction with the active galactic core Seyfert 2 in the constellation Canes Venatici. It was recently estimated to be 23 ± 4 million light years from the Milky Way, but different methods yield a distance of between 15 and 35 million light years. The Whirlpool Galaxy is one of the most famous galaxies in the sky. The Whirlpool Galaxy and its neighbors (NGC 5195) are easily observed by amateur astronomers, and the two galaxies can even be seen with binoculars. Whirlpool galaxies are also popular targets for professional astronomers, who study them to better understand galaxy structure (especially structures associated with spiral arms) and galaxy interactions.

How big is Jupiter
A Giant in the Solar System: Jupiter is four times as wide as Earth, which is approximately 150,000 kilometres round. Jupiter's gravity is also very strong and it has a gaseous atmosphere that spans more than five times the planet's radius in height. This means that even if you could run around its entire circumference, you would only touch the top of its cloud layer. With this significant mass and a dense, swirling atmosphere, Jupiter is able to maintain a quite stable orbit around the sun.
So how big is Jupiter actually? Well, Jupiter has a diameter of around 142.984 km / 88.846 mi at the equator, and a diameter of about 133.708 km/ 83.082 mi at the poles.
Moon up close
The moon, when observed up close, reveals a stunning and intricate landscape that is often not visible from a distance. Astronauts who have been fortunate enough to visit the moon describe its surface as a desolate yet captivating expanse.From a closer vantage point, the moon's surface is covered in a layer of fine, powdery dust known as regolith. This regolith is the result of countless impacts by asteroids and meteoroids over billions of years. It gives the moon a unique texture, resembling a mixture of fine sand and gravel.
One of the most prominent features when viewing the moon up close is its craters. These impact scars come in various sizes, from small pockmarks to massive basins. Over time, some of these craters have been filled with lava, creating dark, flat regions known as maria. These maria contrast with the brighter highland regions, creating a distinct pattern on the moon's surface.
As you explore the moon's surface, you would notice that it lacks any significant atmosphere. This means there's no air to scatter sunlight, resulting in a pitch-black sky even during the daytime.

Earth From Moon
Gazing at Earth from the Moon's desolate surface offers a profound and transformative experience. The sight of our home planet suspended in the void of space instills a sense of humility, appreciation, and a deeper understanding of our place in the cosmos. In this exploration, we delve into the captivating perspective of Earth.
Viewing Earth from the Moon
Viewing Earth from the Moon would be a remarkable experience. Astronauts who have been fortunate enough to travel to the Moon have described the sight of Earth from its surface as a profound and awe-inspiring moment. Here's what you might expect to see and feel:
Earth would appear as a beautiful blue and white orb hanging against the blackness of space. This iconic view has been famously referred to as the "Blue Marble." The vibrant colors of our planet, with oceans and continents visible, create a striking contrast against the dark lunar landscape.
From the Moon, you'd notice that Earth's atmosphere appears relatively thin and fragile
