These are all satellites currently in orbit of the Earth 🛰

Natural Radio Signals from Venus

When the Parker probe was launched in 2018, no one hoped to get any information about other planets. Parker's goal was to explore the Sun.

But in 2020, when the probe flew near Venus at close range, it managed to record a radio signal coming from the planet. Now we have a chance to hear it.

Prague Chimes

The astronomical clock face was created in Prague back in 1410. What is surprising, the clock is the third oldest astronomical clock in the world. And it still works today.

✅ The dial shows Babylonian, Central European, Old Bohemian and sidereal time. Other indications show the position of the Sun among the zodiac signs and the current lunar phase.

When are we moving? 😅

A Mesmerizing Spectacle

The S2 star orbiting a supermassive black hole at the center of the Milky Way.

Another Universe Before the Big Bang

American astrophysicists have used mathematical tools to study the inhomogeneity of relic cosmic radiation.

They believe that it arose immediately after the birth of the universe. Participants of this study are sure of this fact, and there is a confirmation of the Big Bounce theory, whereby the emergence of our Universe was caused by the collapse of some "previous".

This Object Can Be Seen Even With Powerful Binoculars

That's probably why the M57 Ring has become the most popular observation object for astronomy enthusiasts.

The M57 Ring Nebula has an oval shape, with a star at its center. Its radius reaches about 1/3 of a light-year.

Solar Protoplanetary Disk

Roughly 4.6 billion years ago, a giant cloud of hydrogen and dust exploded under its own weight and formed the disk called the solar nebula.

Most of the substance concentrated in the center and created the Sun, while the rest of it formed the planets and other objects in the system.

The Giant-Impact Hypothesis

Computer modeling gives us a brilliant opportunity to create a visualization of processes in the cosmos. This visualization, which depicts the theory of the Moon's formation, was created by Dr. Robin Canup.

The theory of the impact formation of the Moon has many advocates. They claim that the satellite was formed as a result of a collision between Earth and a space object about 4.5 billion years ago.

When we hear "solar system," all we imagine is the Sun and the planets...

What everyone forgets is the satellites. Just look at the number of them.

How Far is the Moon from Earth?

Some sources argue that all the planets in the solar system can be placed between the satellite and Earth. But there is a small caveat to this statement😉

They will only fit when the Moon is the farthest away from Earth. Since the orbits of all celestial bodies are ellipses and the Moon isn't an exception.

It is better to answer this question⤴️ with numbers. The distance from Earth to the Moon amounts to 384,400 kilometers.

"I'm burning, farewell, comrades!"

This was the phrase Yuri Gagarin said during the final stage of the flight.

In 1961, the year of the first flight into space, no one had a clear idea of how to overcome the dense layers of the atmosphere during the descent.

During his descent, Gagarin saw flames raging in the porthole and concluded the spacecraft was on fire. As a matter of fact, such a phenomenon occurs during every flight when the heat-resistant shell of the spacecraft is rubbing. Now, every astronaut is aware of this and ready for the fiery spectacle.

Tea ball in Space

Note, it has its own rotation around the axis. It is only when all transients have stabilized and there is a constant rate of rotation that the liquid transforms into a full ball shape and the air, which is inside, gathers in the center.

Thus, this is nothing more than a manifestation of the centrifugal force.

This is not a photoshop😱

Jupiter's turbulent atmosphere

The photo was taken on Jupiter in the early morning hours when the Sun was illuminating the top of a massive thunderstorm.

📌And those three bright celestial bodies are the Galilean satellites.

Astronauts from the ISS can observe 16 sunsets and sunrises within 24 hours😱

How is this possible?

The orbital velocity of the ISS is 7.6 km/sec. So, it takes the station only 92 minutes to fly around the Earth.

The first space hotel is expected to open in Earth's orbit by 2027

The space station will consider not only hotel rooms, but also places for building private villas.

The first ever space hotel is planned to be built in this decade.

Earth Rotates Faster and Faster Every Year

Scholars have analyzed that the current speed of the Earth's rotation has hit its maximum for the past 60 years. If it keeps going this way, estimated and actual time may differ by 0.9 seconds by 2026.

And then, we would have to turn down Earth time for the first time❗️
