A few facts about Neptune 🔵 - Due to its very significant distance from Earth, Neptune is an extremely difficult target to study. It has only been visited by one spacecraft so far in its history. That honor went to the Voyager 2 probe, which made a close flyby of the planet in August 1989. - Neptune has its own ring system, consisting of five main rings. They are much smaller and dimmer than Saturn's famous rings and are mostly made up of particles likely covered in organic material, giving them a reddish hue. - Neptune is the most distant planet in the solar system. It orbits at a distance of about 4.5 billion kilometers from Earth. Neptune makes one revolution around the Sun in 164 years.
Amazing Sounds of Saturn 🪐 In this video you can hear, transformed for the human ear, the sound that Saturn's rings make.
A few facts about Mars 🪐 - The satellites of Mars were named after twin brothers from Greek mythology. - An elephant on Mars will weigh less than on Earth. All because of the weak gravitational force. If an elephant weighing 5000 kg got to Mars, it would weigh about 1900 kg there. - This planet has the highest mountain in the solar system. It's called Olympus. Its summit is 28 km from the surface.
Their decision to leave Constantinople proved timely. In 1261 Michael VIII Palaiologos, the ruler of the Empire of Nicaea, took Constantinople, promptly burned the Venetian quarter and re-established the Byzantine Empire.

Saturn is somewhere near ... 🪐 🪐 This is a modeled image of Saturn. This is what Saturn would look like if the planet were at the same distance from Earth as the Moon
Did you know the price of one NASA spacesuit? 🧑‍🚀 The first spacewalk by a team of female astronauts was postponed due to a spacesuit shortage and will take place in October 2019. NASA has invested more than $200 million to develop new spacesuits. Despite that, the agency has only 11 usable space suits on hand, according to a report by Inspector General Paul Martin. According to NASA engineer Pablo de Leon, each suit weighs more than 150 kilograms and costs $22 million.
Ball-shaped cluster ⭐️ This is a cluster of gravitationally bound stars in the form of a near-sphere shape. The concentration of stars in the center of the cluster is higher than at the outskirts. Clusters can include from tens of thousands to many millions of stars.
Earth's history in one year 🌍 If you compress the entire history of the Earth (4.5 billion years) into one year, you get: - Life on Earth appeared in mid-March - The first land animals didn't appear until late November. - Age of the dinosaurs December 8 through December 25 - The emergence of the human mind December 31 at 23:40. - The Industrial Revolution hit just 1 second before New Year's Eve.
A Day in Space History 🗓️ "Apollo 15 lifted off from the Kennedy Space Center in Florida at 13:34 UTC on July 26, 1971. After about one and a half revolutions around the Earth, astronauts David Scott (crew commander), Alfred Worden (command module pilot), and James Irwin (lunar module pilot) switched on the third stage engine and put the craft on a flight path to the Moon.
Why does Uranus have a blue color? 🪐 Uranus' atmosphere is made up of gases such as hydrogen, helium, and methane. Methane, which is found in the upper layers of the atmosphere filters out all of the Sun's red light and reflects the Sun's blue light back into space, giving it a blue appearance.
We are all a little bit stars 🌟 All humans, without exception, are stars, and this is not an exaggeration at all. Almost all of the chemical elements that make up humans (calcium, carbon, nitrogen, oxygen and about 60 other "ingredients") are also part of these celestial bodies. In fact, at the molecular level, we are made up of cosmic dust, i.e. the remnants of exploded supernovae.
Animation of a massive explosion Micronova 💥 Micronovae are powerful explosive events, but not very noticeable on an astronomical scale. They result in the release of much less energy compared to new flares. Both events occur on white dwarfs - dead stars with masses like the Sun, but comparable in size to the Earth.
A little bit of dark matter 🗾 Dark matter is a form of matter that does not enter into electromagnetic interactions (does not emit light). It makes up part of the universe, has a gravitational effect, and affects the motion of stars in our own and other galaxies. It makes up 22% of the universe. It is important not to confuse antimatter and dark matter. Antimatter is matter consisting of antiparticles.
99 percent of the mass of our solar system is sun ☀️ Our star, the Sun, is so dense that it occupies a whopping 99 percent of the mass of our entire solar system. That's what allows it to gravitationally dominate all the planets. When the Sun dies, it will become a red giant and consume the Earth and everything around it. But don't worry: it won't happen in the next 5,000,000,000,000,000,000 years.
Truly mesmerizing 🤩 This is a video showing the movement of 40,000 stars in the Milky Way over the next 400,000 years. It's very beautiful ...
Ever wondered about death by asteroid? 💫 Now you can see it with your own eyes. This is what the end of the world will look like if the largest asteroid in the solar system (according to Discovery) collides with the Earth.
The process of spaghettification is not about food 😉 Spaghettification is an astrophysical term for the violent stretching of objects vertically and horizontally caused by a large tidal force in a very strong inhomogeneous gravitational field. This animation shows the absorption of a star by a black hole
Earth speed fact Every minute, the Earth travels 19,300 kilometers. Note another interesting fact about our planet, so, its rotation around its axis is made in 23 hours and 56 minutes. What takes another four minutes? They are needed for the Sun to return to its original position. These 4 minutes accumulate one day - February 29, once every four years.
NASA published sonification of the black hole at the center of the Perseus cluster of galaxies 🪐 Their interest was sparked by the fact that the black hole emits pressure waves that can be converted into sounds. Recently, scientists from the Marshall Space Center of the National Aeronautics and Space Administration (NASA) of the United States published a small record of how the black hole "sounds".
The concept of Galactic collisions 🔭 Galactic collisions 🔭 Galactic collisions. Galaxies, like stars, can collide and merge with each other as a result of gravitational interaction. These galactic collisions can create exciting and unpredictable phenomena such as the formation of new stars and black holes.
If two pieces of the same type of metal touch in space, they will glue 🧲 This amazing effect is called cold welding. It happens because the atoms of the individual pieces of metal can't know they are different pieces of metal, so the pieces stick together. This will not happen on Earth because air and water separate the pieces of metal. This effect is important for spacecraft construction and future construction of metal structures in a vacuum.
A day in the history of space 🚀 July 23, 1972 Launch of the first artificial Earth satellite (Landsat-1, USA) into orbit to explore our planet's natural resources from space.
One day on Venus lasts 224.7 "Earth" days, that is, more than 7 months 🪐 Venus is also the slowest rotating planet, as can be seen by looking at its poles. While absolutely all planets in the solar system have experienced flattening at the poles due to the speed of their rotation, Venus shows no signs of it. As a result, it takes Venus about 243 Earth days to go around the system's main luminary once. This may seem strange, but it takes the planet 224 days to complete a full rotation around its axis, which means only one thing: a day on this planet lasts a very long time
Rosette Nebula 💫 The NGC 2237 nebula is large in size and is located in a very beautiful region called the Molecular Cloud of the Unicorn constellation in the Milky Way band. It is quite bright and with its characteristic appearance and color resembles a rose, although its more established name is Rosette.
In space it is better without tears 😪 If you cry in space, the tears will stay on your eyes and face. In weightlessness, tears really don't drip and stay on the cornea of the eye, but they can be collected with a tissue or handkerchief, which is what astronauts do. If you keep crying, the liquid can inflate into a bubble in front of your eye.
The moon is getting farther and farther away from us ... 🌑 Every year our Moon is clearly and inexorably moving away from the Earth - just by a tiny bit, about two centimeters, which is barely visible to the naked eye. Alas, this process can neither be stopped nor reversed. The forces of gravity are invisible and unwavering, and no matter what we do or how we feel about them, they will continue to nudge the moon. In many millions of years, we will be an impressive distance apart.
White space dwarfs 💫 At first you might think that "White Dwarfs" - are some fairy tale creatures from another sci-fi story, but no. White dwarfs are the name given to stars that lack their own sources of thermonuclear energy and glow due to their thermal energy, gradually cooling down over billions of years. The closest known white dwarf is Sirius B, which is 8.6 light-years away.
Amazing footage 🔭 This is the kind of footage the Hinode satellite managed to capture during the solar eclipse, October 25, 2022. It was a private eclipse of the Sun with maximum phase.
One of the largest meteorites to hit the earth. Barringer Crater ☄️ The 48.78 m long meteorite fell about 50,000 years ago in the northern part of the Arizona desert, forming a crater 1.6 km wide and 173 m deep. Currently, the Barringer crater is very popular for tourists to visit. Scientists believe that the meteorite collided with the Earth, moving at a speed of 4602 km / h, and the power of the explosion is 150 times greater than the nuclear bomb dropped on Hiroshima.
Winds on Venus blow at 500 km/h 🪐 Venus is similar to Earth in composition and size, but very different in appearance and surface conditions. The planet's atmosphere consists of carbon dioxide and sulfuric acid vapor heated to high temperatures and is very dense. In the mesosphere of Venus at an altitude of 85-100 km ozone is 10 thousand times less than in the atmosphere of the Earth. And the content of sulfur dioxide varies significantly over several days. Thanks to a study using starlighting, when the spectrometer followed the stars at their rising and setting over the horizon of the planet, scientists were able to find out the concentration of the main gas of the Venusian atmosphere. This distribution of ozone indicates that the gas interacts with chemical compounds that winds carry from the day side of the hemisphere to the night side. And because the atmosphere of Venus rotates 60 times faster than the surface of the planet, the wind speed here can be up to 500 km / h.
Glass rain - business as usual 🌧️ Exoplanet HD 189733b, a beautiful blue dot in the black space of space, is superficially very similar to Earth. But that's where the similarities between the two worlds end. Rain in this world comes not from water, but from molten glass. NASA experts say that the blue color of the planet is not because it has many oceans. Silicates in the clouds in the upper atmosphere have a characteristic color.
A planet made of graphite and diamonds 💎 Another mysterious planet astronomers have discovered in the constellation of Cancer. According to employees of Yale University, it is twice as large and eight times heavier than Earth. But the main thing - Janssen almost entirely consists of graphite and diamonds. And the share of the latter accounts for a third of its substance. Forbes estimated the planet's value at $26.9 billion. By cosmic standards, the giant diamond is located not far from the Earthlings - only 40 light years. The speed of rotation is so high that one year there is equal to 18 Earth hours.
Can anyone explain how to hit a Streak?
From far away, and you can't see the Earth 🌍 The small white dot in the photo is our planet, taken by the Voyager I probe. In 1990, from a distance of 6 billion kilometers, this most "distant" of all photos of Earth was taken.
Rain of electrons causes auroras on Mercury 🪐 The acceleration of electrons appears to be due to plasma processes on the dawn side of Mercury's magnetosphere. High-energy electrons are carried from the tail region toward the planet, where they rain on the surface. Meeting no obstacles in the atmosphere, they interact with material on the surface and emit X-rays, resulting in the aurora borealis. Although auroras have previously been observed on Mercury by NASA's MESSENGER mission, the processes that cause X-ray fluorescence on the surface have not been well understood or directly witnessed until now.
Pulsar - what is it? 💥 A pulsar is a small rotating star. There is an area on the surface of the star that emits a narrowly focused beam of radio waves into space. Our radio telescopes pick up this radiation when the source is turned toward Earth. The star rotates, and the radiation stops. The next revolution of the star and we receive its radio message again. Pulsars belong to the neutron star family. A neutron star is a star that remains after the catastrophic explosion of a giant star.

This isn’t the next Facebook. This is a social operating system. Every existing app and platform can already benefit from becoming Lens-compatible. When developers “port” their apps over it’s positive-sum for everyone. More Data + More Users = More Value. To those building natively here: There is room for apps of all scales and purposes, similar to a desktop or mobile operating system. Some apps here will become giants akin to Microsoft Office, Google Chrome, or Adobe Photoshop—universal platforms that become integral to the user's experience. These 'giant' apps are used by virtually everyone because of their broad utility and the network effects that come with widespread adoption. Meanwhile, other apps will carve out their own niches, much like CCleaner, Notepad++, VLC, or WinZip. These are the 'utility' apps that perform specific tasks exceptionally well. They may not be universally known but they garner loyal user bases because they fill a need, solve a problem, or simply do their job better than any other app out there. I encourage every dev right now to take a moment and look at the apps installed on their device. Lens has the capacity to host a similar diversity of applications, each contributing to the overall “Social Operating System” experience in its own unique way. Rather than compete with Facebook I would recommend building with the “Operating System” framework in mind and trying to solve your own niche problem/task first. Not everything has to compete with Facebook’s scale! //////////////////////////////////////////////////// A fun brainstorming game to play //////////////////////////////////////////////////// Find an App or System Setting in your device’s OS and then ask ChatGPT for the Social OS equivalent. Use this prompt: I'm building apps on Lens (a new social networking protocol) and I'm told to think of it not as a Facebook competitor but as a new Social Operating System. They say there's room for apps at all levels, the same as a desktop or mobile operating system. So in that context, what would be the “Google Maps” of this OS? * Social Network Navigation App: This app would map out the social connections between users, helping them navigate through their relationships. It could provide insights into how different users are connected, recommend potential new connections based on shared interests or mutual friends, and suggest paths for reaching out to new people. * Event Discovery and Navigation App: This app could help users find and navigate to events within the social network. Just as Google Maps can help you find physical events and navigate to them, this app could help you find online events happening within the social network and guide you on how to participate. * Content Discovery and Navigation App: This app would guide users through the vast amount of content available in the network. It could use algorithms to recommend content based on users' preferences and behavior, help users explore new types of content, and provide tools to navigate through different content categories. * Trend Mapping App: This app could track and visualize trends within the social network. It could show what topics are currently popular, how trends evolve over time, and how they spread across the network. What would be the Logic Pro? * Social Media Music Studio: This app would allow users to create, edit, and mix music or audio tracks directly within the social OS. Users could then share their creations on their social profiles or collaborate with others. Features might include various sound samples, mixing tools, and the ability to record directly into the app. * Podcast Creation App: This app would provide all the tools necessary to record, edit, and publish podcasts. It could also integrate with various social platforms to promote episodes, engage with listeners, and gather analytics. * Audio Storytelling App: This app could provide a platform for users to create and share audio stories or spoken word content. It could offer tools for adding sound effects, music, and other audio enhancements. * Collaborative Music App: This app would allow users to collaborate on music projects, providing a shared space where they can contribute tracks, mix together, and share their creations. What would be the utility apps?  * Privacy Management App * Content Scheduling App * Analytics App * Curation App * Identity Verification App * Anti-Harassment App * Cross-Platform Search App There’s a ton of opportunity here to build social apps which can sustain your lifestyle without needing to reach 1 billion users.
The man in the photo - lost his wedding ring in space. What did you achieve? 💍 On the second day of the Apollo 16 lunar mission, Command Module pilot Ken Mattingly discovered he had lost his wedding ring. The crew searched all over the ship for it. On the ninth day, it was finally spotted floating out of a hatch while Mattingly was in outer space. Another astronaut, Charles Duke Jr. spotted the ring and tried to grab it, but was unsuccessful. Fortunately, it bounced off Mattingly's helmet and Duke caught it. Imagine: a small ring almost lost in the depths of vast space. However, people have already left a lot of things in space - there's a toothbrush flying around out there somewhere.

Water cloud found in space 🌧️ While searching for water in space, researchers were lucky enough to discover a giant oceanic cloud that is made up of water mist. The cloud is located 12 billion light-years away in the constellation Lynx. Astronomers were able to calculate exactly how much water this cloud contains - more in 140 trillion.
A diamond planet? No, you haven't heard of it 🪐 In 2021, scientists discovered the planet 55 Cancri e, which has been dubbed a diamond planet. Astronomers said that the carbon-rich exoplanet has chemical reactions that scientists have never seen before. The authors even proposed to allocate such objects in a separate class - diamond planets, and 55 Cancri e will be the first in this list.
