The light of the Sun goes to the Earth, breaking the bushes and overcoming the barchans of the internal resistance of our star for 30 thousand years. That is how much time photons need to make their way from the center to the surface of the star. But after that, they need only 8 minutes to touch the Earth and warm the tired hands of the mortar commander with their warmth. The conclusions today are that the light will still overcome the darkness, but it may take a long time... #Astrokhata is still under occupation, but we hope for the best. www.astrohata.com Our...

Today it's about black and white. There is one small but interesting satellite of Saturn - Iapetus. One hemisphere of Iapetus is black as pitch, and the other glistens like snow. It is still not known for sure why this icy block in space is so clearly divided into light and dark. However, that's not all - along the equator of Iapetus runs a series of unnaturally level mountain peaks called Iapetus Wall (height 13 km). There is a theory of its origin - Iapetus once had a ring in orbit, which fell to the surface of the satellite under the influence of gravity. There...

I think Ukrainians got the ability to adapt from the Heavenly slow-walker and this is what she can do - * + 150 degrees and - 273 C * withstand a pressure of 6000 atmospheres * radiation of 500 thousand roentgens (while the lethal dose for a person is only 500 roentgens). * can starve for decades (this is not about us) * More than 100 years without water. * 30 years can be under water at a temperature of -20 °C * the tardigrade has legs, a mouth and teeth * two years - in liquid oxygen at −193°C. * Can be in outer space without problems * The speed of...

Quasars are the brightest objects in the universe (except for supernova explosions). They are also called Lighthouses of the Universe. This is roughly what the quasar P172+18 and its radio jets look like. So far, it is the most distant quasar ever discovered. It is so far away that its light has taken about 13 billion years to travel to us: we see the quasar as it was when the universe was only about 780 million years old. So let our inner light fly through the entire universe and not go out. #Astrokhata is still under occupation, but we hope for the...

Anyone who closely follows my work knows that there are already all the prerequisites for creating ultra-fast Internet, and here's something else - StarLink has announced the launch of special satellites into space that will be able to provide 4G services from space for ordinary smartphones. The service is called Direct to Cell and is being launched alongside Tmobile. In 2024, only messages will be available, then voice and data will be added in 2025. In the future (to which we still have to live) ordinary telephones will work directly through satellites all over...

Continuing the theme of the microcosm - last year The Nobel Prize in Physics was awarded for the future quantum internet. This is the name of the communication networks through which not just electrons or photons travel, but electrons and photons that preserve their quantum states. The main thing that the transmission of quantum states provides (at least theoretically) is the fundamental impossibility of eavesdropping or changing the message, that is, the absolute security of communication. Quantum entanglement is described as a connection between photons that...

And now let's dive into the amazing world of quantum physics. Recently, three scientists received the Nobel Prize in Physics for the so-called photographs of the process of separation of one electron from an atom using an attosecond laser! I did not check it myself, but there is an opinion that this technology will be able to speed up existing computers by a hundred thousand times! And here we will be able to come close to modeling reality as in the matrix - that is, create our own virtual universe (hopefully there will be wine in it). So let's hold on - soon everyone...

Despite the war in Ukraine and already in Israel, this Saturday America (unfortunately only there) will be visited by a stunning astronomical spectacle - an annular eclipse, during which the Moon crosses the Sun and leaves a "ring of fire" around it. An annular eclipse occurs when the Moon is too far from the Earth and does not cover the entire disk of the Sun. As stunning as the ring of fire is, it's also a preparation for next year's Great North American Eclipse — a total eclipse on April 8, 2024 that will cover Mexico, the United States and Canada. I wish...

The James Webb Space Telescope has discovered "planets" the size of Jupiter that move freely in space and are not gravitationally bound to any star. Scientists were especially surprised that these objects apparently move in pairs. According to one version, the planets formed in that part of the Orion nebula, where the density of matter was insufficient for the formation of full-fledged stars. And if you imagine that girls live on one planet, and boys live on another, and all this happens in the dark (because there is no Sun nearby).. Cybernetics engineers begin to...

Continuing the theme of winds, ships and the lively twinkling of the Universe - I want to show you - the Witch's Head Nebula (IC 2118) - a reflection nebula in the constellation Eridanus, which is located at a distance of about 900 light years from us. In this image, the witch's face looks up at the bright star Rigel (Beta Orion [β]) just beyond. It took 11 hours and 40 minutes to collect light from these stars in a telescope to capture this image of deep space. And now, closing your eyes, begin to breathe more slowly, and imagine yourself as this world traveling...
