The Rosette Nebula.

A giant emission nebula that is about 5,000 light years away, and the size of its central part is about 50 light years!

Atlas of the orbits of our solar system

On the photo you can find the orbits of almost any bodies in the solar system, from large planets to objects that are only 10 kilometers in diameter.

In this picture you see Halley's comet 💫

Just imagine...
The photo was taken on June 6, 1910, at the York Observatory of the University of Chicago.

Comets highly resemble asteroids ☄️

Still, there are a few differences, they contain more ice, methane, ammonia, and other compounds.

They develop fuzzy, cloud-like shells called comas. And also form a tail as they fly closer to the Sun.

What threats will humanity face when exploring deep space? 🧑🏼🚀

Among the main real dangers are space vacuum, space radiation, weightlessness and lunar dust (if we take into account lunar exploration).

The most dangerous of these should be considered space radiation. It includes electromagnetic radiation and high-energy charged particles, primarily protons.

Washing machine capable of working on the Moon

Meanwhile, a manufacturing company is developing a combined washer-dryer that could work on the Moon or Mars. It requires a minimal amount of water and detergent.

Such a machine could also be useful in arid regions of the Earth 🤔

The size of the red giant Betelgeuse

The white ball in the animation is the Sun, the 8 planets orbiting it are shown next, and the red giant is the star Betelgeuse.

Timelapse of the vast northern lights

Such an amazing phenomenon was filmed by French astronaut Thomas Pesquet.

📌 The northern lights are the luminescence of the upper atmospheres of planets possessing a magnetosphere (their interaction with charged particles of the solar wind occurs).

Oumuamua is misleading scientists again

Experts doubt it could be a "nitrogen iceberg"🤷🏻
⠀
The Oumuamua space object is the subject of heated debate among astronomers. Some suggest it's part of exo-Pluto, others that it's a giant asteroid sent by another civilization. And a new study suggests that Oumuamua definitely cannot be a nitrogen iceberg.

Galaxy R5519 shaped like a ring, surrounded by a scattered halo

A void with a diameter of 30 thousand light years (about a third of the Milky Way's diameter) lies in its center.

As a result, the radius of the ring galaxy is 1.5-2.2 times larger than that of the Milky Way, with almost the same mass.

Dear The Guardian,
Trust you are doing well.

I don't understand why you have to poke your nose everywhere? Did we ask you why the United Kingdom still has a king and why you had to change 3 Prime ministers in a span of 3 months? Did we ask you why your economic growth is negative? Did we ask you why the UK only country seeing recession? Did we?

Are you not the same country which looted 57 trillion dollars from my country? Are you not the same country which took our food and funded your army in the second world war, which killed nearly 3 million civilians during the Bengal Famine? And now you are teaching us democracy? Where was democracy when you ordered the Jallianwala massacre.

I suggest you focus on your economy and your government. Don't you remember how your country thanked an Indian company for ordering airplanes?

Get out of the superiority complex. We don't need lessons of democracy from a country which invaded half of the world and made them a colony. Please!

Warm Regards,
An Indian.

This mission demonstrated the ability to repair satellites directly in orbit.

The life of a star is determined by its mass

Massive stars have a short life, ending in a supernova explosion or the formation of black holes.

Smaller stars live longer, ending their lives as white dwarfs.

The Cat's Eye Nebula is a planetary nebula formed after the death of a star with a mass approximately equal to that of the sun.
