Exoplanet Janssen An exoplanet is located in the planetary system of the sun-like star 55 Cancer A in the double system 55 Cancer (HD 75732). The exoplanet orbits the sun-like star. The planet is very close to its star, and always faces one side of it. The period of orbit around the star is 17 hours. The surface temperature reaches 2400°, causing the side facing the star to be a molten surface.

Do all spiral galaxies have a black hole in the middle? Nobody knows this for sure, but it is likely that most spiral galaxies contain a supermassive black hole, and sometimes more than one. There are two reasons for our uncertainty. First, we physically cannot survey all spiral galaxies in the Universe. Second, theoretically, galaxies are not obliged to have a black hole at their center - their stars will be held together as it is. Likewise, there is clear evidence that black holes may have been very important, if not obligatory, for the formation of galaxies in the early Universe. In that case not only in the middle of spiral galaxies, but also in all other galaxies there could be compact supermassive objects.

A cosmic object with a mass of 66 billion solar masses! It seems unbelievable, but such an object does exist - in the constellation of the Hound Dogs. This object is a heavy supermassive black hole, which is the center of the quasar TON 618. Luminosity of the quasar is 140 trillion times more than the solar! It is one of the brightest objects in the known universe. But we cannot see it through the telescope with our eyes anyway - the quasar is 10.5 billion light years away from us.

May one have a cat on the ISS? Domestic animals on the ISS are an unacceptable luxury. They need oxygen, water, food, sanitary conditions. Moreover, the issue of fur flying everywhere will be very acute. The poor animal will face a lot of trouble in space. Cats have well-developed vestibular apparatus, so that in microgravity conditions the tail will twist and turn like a whirligigig. *The first cat in outer space is pictured here.

Vagabonds in Space In the endless expanse of the Universe, orphan planets, a.k.a. tramps, or alien planets, fly in the darkness and silence. Once many of them had their own star. But these planets have gone out of orbit and now wander in space in sad loneliness. ✔️In spite of their seeming elusiveness, astronomers have been able to locate several distant planets thanks to the method of gravitational microlensing. In September 2020, the first Earth-mass orphan planet, OGLE-2016-BLG-1928, was discovered in the Milky Way Galaxy, unconnected to any star.

From a protostar to a nebula Every star follows a complex evolutionary path over millions and billions of years of existence. It is born from a protostar in a "stellar cradle," when thermonuclear reactions begin in its interior. The process of birth of small stars like our sun takes several tens of millions of years. The life of such a star lasts for another few tens of billions of years. In the final stage, when the fuel in the core comes to an end, the small star turns into a red giant. After a long period of relatively calm expulsion of matter from the surface, it drops the envelope. That shell becomes a planetary nebula, and the core of the star becomes a white dwarf. 📌The photo illustrates a collage of 100 planetary nebulae.

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.
