On March 29, a solar eclipse will be visible in Ukraine from 10:50 a.m. to 2:43 p.m. Kyiv time. The war is unlikely to end after this, but it will be interesting to watch the astronomical phenomenon....

Many astronomers are currently watching the constellation Corona Borealis (CrB) for the long-awaited outburst of the repeating variable star T CrB. When that happens (possibly in the next few weeks), "T Cor Bor" is expected to brighten dramatically, a couple thousand times in a matter of hours. Look just above Arcturus and slightly to the left. If the sky is dark, you'll see a set of stars shaped like a cup without a handle. That's the constellation Corona Borealis, the Northern Crown. Only one of its seven stars is very bright, and it's called Alphekka, which is...

Stars are giant balls of hot gas composed mainly of hydrogen and helium. And why are they hot and bright? Thanks to nuclear fusion, temperature, pressure and mass are all in a delicate balance up to a certain point. 99% of the mass of our solar system is the Sun. It is not for nothing that our Star has been compared to God since ancient times. And when the first ray of the Sun touches your face in the morning - remember space, #Astrohata and red dry of course)...

#Astrokhata about serious things. There is speculation that comet C/2023 A3 will have a brightness of -2.5 to -3 m this October and will actually become the brightest this decade, if it survives its approach to the Sun, of course. So everyone I know and don't know must live to see this event to tell posterity. Look up and under your feet, my dears...

If we wanted to reach the nearest star after the Sun, Proxima Centauri, by car, it would take us about 50 million years at a speed of 100 km/h. From this we can come to an interesting conclusion - the main resource of our life is this TIME and also the mind so as not to waste this time in vain. #Astrokhata is still under occupation, but we hope for the best. www.astrohata.com Our Telegram - https://t.me/astrohatacom Instagram - https://www.instagram.com/astrohata/ #Sun #time #proximacentauri...

You can endlessly look at water and fire, but the most magical thing is open space. At the center of the Heart Nebula (IC 1805) is the star cluster Melotta 15, which illuminates the surrounding gas and dust. In addition, there is also the Soul Nebula (IC 1848). And all this is about 7500 light years away from us in the constellation Cassiopeia. In the heart, the soul is still the astronomers of romance) #Astrokhata is still under occupation, but we hope for the best. www.astrohata.com Our Telegram - https://t.me/astrohatacom Instagram...

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...
