✨The ocean on Jupiter is larger than any other in the solar system but unlike Earth's oceans, It's made not of water but of metallic hydrogen. The ocean’s depth is a mind-blowing 25,000 miles, it's almost the same as the distance around the Earth✨

What is Event Horizon?

✨A black hole's “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos. Matter and radiation fall in, but they can't get out.
💫According to Einstein's theory of special relativity, nothing can travel faster through space than the speed of light✨

What is the speed of dark?

✨Most of us already know that darkness is the absence of light, and that light travels at the fastest speed possible for a physical object. So, what does this mean? In short, it means that, the moment that light leaves, darkness returns. In this respect, darkness has the same speed as light✨

💥The Bubble Nebula

✨Also called NGC 7635. The nebula is 7,100 light-years away, in the direction of the Cassiopeia Constellation.

It is really a bubble that has been inflated by a massive star with its stellar wind. The star has a mass 45 times that of the sun and a luminosity hundreds of thousands of times greater✨

Why do astronauts not fly to the dark side of the Moon?

✨The point is that there is no radio communication with Earth on the other side of the Moon.
--One solution to this problem is to use a constellation of satellites to send a signal, though this approach is expensive and difficult.

‼Sending people to the Moon without constant communication is an unreasonable risk✨

The Solar System has its own tail

✨It looks most like the tail of a comet. We call it the heliotail. Nothing was known about it for the simple reason that the tail consists of particles invisible to traditional instruments.

✔️ The heliotel stretches 13 billion kilometers from the edge of the solar system✨

The Universe has the same temperature everywhere (-454.756°F)

✨A snapshot of the Cosmic Microwave Background – heat left over from the Big Bang – when the Universe was just 380,000 years old, as seen by the Planck Telescope. It shows tiny temperature fluctuations that correspond to regions of different densities: the seeds that would grow into the stars and galaxies of today✨

Why has Mars lost its atmosphere?

✨Nowadays, Mars is a cold and barren desert. Perhaps it was the loss of the atmosphere that caused such a change.

Unlike Earth, Mars does not have a strong magnetic field protecting the red planet from the flow of solar charged particles.

The solar wind crashes unhindered into the upper atmosphere of Mars and pushes ions into space✨

When is Mars to become a habitable planet?

✨The problem is that Mars it cannot hold a dense atmosphere due to its low gravity.

As a consequence, any attempts to make Mars similar to Earth must involve either constant feeding of its atmosphere, or a substantial (several-fold) increase in its mass. Both options are far from being realized.

In general, this cannot happen in the next centuries✨

Why aren't the planets falling on the Sun?

✨Most of us are aware that the Sun contains 99% of the total solar system mass and everything in it revolves around the Sun.

Based on the law of universal gravitation, all bodies are attracted to each other: such as the Sun and Earth, the gravitational force is about 3.35×10^22N. And at first glance, with such a huge force, the bodies would have to come closer to each other, or rather, our planet would have to fall on the Sun.

As well as planets do not fall into the sun because they are moving too fast in the tangential direction. As they fall toward the sun they travel tangentially just enough that they never get very close to the sun. They fall around it, in effect✨

Planet Tajikistan

✨There is a dwarf planet in the solar system, which is located in the region between Mars and Jupiter, was named "Tajikistan”.

It was named after the Tajik scientists who contributed to the development of astronomy✨

Roughly 5-6 tons of meteoritic material falls to Earth per day☄

✨It would seem to be a huge figure. But most meteorites burn up before they reach earth: When a meteorite enters the atmosphere, its speed can reach 11 to 72 km/sec. Due to the friction of the air, it ignites and resembles a bright fireball.

Sometimes, the internal structure of the meteorite is heterogeneous and unstable: then it explodes in the air, and its debris falls to the ground. This phenomenon is called a meteor shower✨.

A hidden supermassive black hole in a dwarf galaxy

✨It was discovered in the Constellation Hound Dogs - in the dwarf galaxy Mrk 462, about 110 million light years away.

Discovered black hole has a mass of about 200 thousand solar masses. It is one of the smallest supermassive black holes. The hole was found by NASA's Chandra X-Ray Space Observatory, launched in 1999.

The agency called the discovery one of the first cases where a heavily hidden supermassive black hole was found in a dwarf galaxy✨
