Happy 71st birthday @brianmayforreal 🙌❤🎊
I have to admit back then in the "dark ages" when I listened to Queen music but hadn't seen any videos or hadn't gotten to know our dearest Freddie Mercury I could recognize the band by Brian's big bushy hair 😂
I mean he really stood out in the pictures...so yeah if I saw band posters somewhere and I couldn't make sure which one was Queen, Brian's hair would come to my aid 😁
And it hasn't changed after all these years not really... well except for the color...
We Queenies all know I'm sure but still I wanna say it! 📢Not only is this man one of the greatest guitar players EVER but he also has a freaking PhD in astrophysics. And he's the Chancellor of Liverpool John Moores University for God's sake! 🎓
AND he keeps reminding us everyday that real rockers are all animal lovers, in his case, with a soft side for badger rescuing and hedgehog cuddling 🐾
Gotta say it's not that often you meet a rock band whose members are both very artistic AND really smart. 📚🙌
P.S. Brace yourself for all the posts tonight 😉😎.
The gas giant Saturn is well-known for its beautiful and sprawling planetary rings. However, when viewed from certain angles, the majestic rings appear as nothing but a thin line. In this image (which is my favorite of Saturn), the actual structure of the rings is only exposed by the shadow they cast onto the planet (left side of the image). I have rotated the original image 90 degrees counter-clockwise simply to give you a new perspective on the planet. To add to this already magnificent image, the icy moon Enceladus is visible just left of the ring in the center of the image. As many of you know, Enceladus is a front-runner in the search for life outside Earth. The last obvious feature of this image is the difference in color between the two hemispheres. The northern hemisphere of Saturn appears blue here due to a relatively cloudless portion of the sky that scatters blue light more efficiently than red light. The southern hemisphere is dominated by a gold color, which could potentially be the result of thicker and higher cloud cover. The second image captures the same phenomena, and moon, from a different angle.
The Cassini mission provided thousands of spectacular images, and the spacecraft dramatically ended its mission on 09/15/17 with a plunge into the upper atmosphere of its host planet Saturn.

The tardigrades, also known as the water bear or moss piglet, are microscopic 8 legged, slow moving (like myself) animals that have to be the coolest creature in the entire world plus its a favorite of mine! Why? Tiny, they are consider one of the toughest if not the toughest animals to walk among Earth. Tardigrades can be found in lichens and mosses but there body composition, anatomy, and physiology make them near omnipotent living in extreme environments. Due to their biology nature they can withstand temperatures above 300 degrees F to below -300 degrees F. Tardigrades have been send to outer space, a dangerous environment to humans and other animals, yet to them its nothing. Let me rephrase that, they can survive in the VACUUM OF SPACE! Much respect to you tiny moss piglet. You do you. #astrophysics#astronomy#spacenerd#space#follow#tardigrade#astrobiology#aliens#respect#mosspiglet#scienceiscool#animals

Great explanation of the #Schwarzchild radius by @astrophysics.ig 🖤🖤🖤
General relativity predicts that as an object collapses to form a black hole, it will eventually reach a point of infinite density. What that really means is that the theory of relativity breaks down at this point, and no one knows what happens at the center of a black hole - we would need a viable theory of quantum gravity in order to understand this.
But here's something that you might find useful: when we talk about the "size" of a black hole, we usually talk about something called the Schwarzschild radius. The Schwarzschild radius is the "point of no return" - once you get closer to the black hole than it, you can never escape.
Consequently, the escape speed at the Schwarzschild radius is equal to the speed of light, and the value of the Schwarzschild radius works out to be about (3x105 cm) x (M / Msun), where M is the mass of the black hole and Msun is the mass of the Sun. (Typically, M for a black hole in our galaxy is around 10 times the mass of the Sun, but for supermassive black holes at the centers of galaxies it can be millions or even billions.)
There is a rough analogy between a black hole and an atom. In both cases, the mass is concentrated in a tiny region at the center, but the "size" of the object is much bigger. You can use the Schwarzschild radius to calculate the "density" of the black hole - i.e., the mass divided by the volume enclosed within the Schwarzschild radius.
This is roughly equal to (1.8x1016 g/cm3) x (Msun / M)2, where M is defined as above. From the point of view of an outside observer, this might as well be the actual black hole density, since the distribution of matter within the Schwarzschild radius has no effect on the outside.
Black holes are one of the most intricate, yet fascinating things in the universe. At first, black holes used to be science fiction. But with plenty of observations, tests, and mathematics of course, we have proven their existence. Gravitational Lensing showed us how these immensely dense objects warp space and time. But what exactly is inside of a black hole? Many scientists have included that in the Centre lies the singularity, this is where matter is permanently destroyed. But could there be something otherwise? Where as though matter is not destroyed, but yet converted into something else? Hawking publicized his theory of radiation emitting from black holes. As this happens, the black hole itself stars to lose mass, and vanishes. But..Into what exactly? Well, that is the question. There is still a lot of research and observations that have to be done involving black holes, but we know a great deal about them, how they formed, and possibly, how they die. Personally, I think that the matter that goes inside a black hole is converted, and reassembled. Though if any human were to go past the event horizon, their atoms would be stretched apart, and they would surely be dead. But do the atoms themselves really disappear? Or does there really lie another dimension, such as the tesseract? We are destined to find out.

Earth and the Moon have been close partners for about 4,500,000,000 years. Although the Moon only has a diameter of 3,474 km across, it is very close to Earth being only 384,400 km away, which, in the grand scheme of the universe, is on our doorstep. This fascinating place influences our planet in many ways; it has a slight gravitational pull on Earth, which creates tides; high tides happen when a place is aligned with the Moon, and low tides happen when a place is at right angles to the Moon. This place is also the only place in our solar system that humans have visited (besides Earth). In the 1969 Apollo 11 mission, astronauts Neil Armstrong and Buzz Aldrin were the first men to step foot on the Moon, and since then, 10 more men have walked on the Moon. The Moon goes through a cycle of phases every 29.5 days; it turns from a new Moon, to the waxing crescent, to the first quarter, to the waxing gibbous, to the full Moon, to the waning gibbous, to the last quarter, to the waning crescent, and back the the new Moon. This is because as the Moon orbits Earth, the Moon reflects light from the Sun. The Moon has a thin crust of granite-like rock, and a small metal core. The Moon has a thin atmosphere containing argon, helium, neon, sodium, potassium, and a small amount of hydrogen

Sharpless 2-106 (Sh2-106 or S106 for short) is a bipolar emission nebula and HII region. It measures about 2 light-years long by 0.5 light-year across and is located about 2,000 light-years away in the constellation Cygnus, in a relatively isolated region of the Milky Way.
Despite its appearance, Sh2-106 is not a planetary nebula, but a giant molecular cloud and star-forming region. Twin lobes of super-hot hydrogen gas (glowing blue) stretch outward from the central star, what creates the “wings”. This image also reveals ripples and ridges in the gas as it interacts with the cooler interstellar medium.
The massive, only 100,000 years old central star (S106 IR), which could be up to 15 times the mass of our Sun, is still shrouded in dust and gas at the centre of the nebula. It is responsible for the surrounding gas cloud’s hourglass-like shape and the turbulence visible within. Eventually its light will break free of the enveloping cloud as it begins the relatively short life of a massive star.
Dusky red veins surround the blue emission from the nebula. The faint light emanating from the central star reflects off of tiny dust particles. This illuminates the environment around the star, showing darker filaments of dust winding beneath the blue lobes.
Detailed studies of the nebula have also uncovered more than 600 hundred brown dwarfs which may someday create a small cluster. These “failed” stars weigh less than a tenth of our Sun. Because of their low mass, they cannot produce sustained energy through nuclear fusion like our Sun does.

“Per non assuefarsi, non rassegnarsi, non arrendersi, ci vuole passione. Per vivere ci vuole passione”, diceva #OrianaFallaci.
Maura Tombelli, la donna delle stelle, di passione ne ha e ne trasmette veramente tanta con le sue storie sull’Universo, le costellazioni, i pianeti e le stelle.
Le brillano gli occhi quando ne parla e le sue labbra non smettono di sorridere.
È una donna che ha avuto coraggio, che ha inseguito a tutti i costi quella che era la sua più grande passione fino a “toccare il cielo”, che come dice lei non ti può tradire.
Le persone sì, possono farlo, il cielo invece è lì per tutti e sarà sempre nello stesso posto ogni volta che vorrai guardarlo.
Dopo averla sentita parlare ieri sera all’Osservatorio Astronomico Beppe Forti vorrei ribaltare il mondo, ho una grinta da leonessa, “se ce l’ha fatta lei, ce la posso fare anche io”, perché è proprio questo che ti insegna Maura: a non sentirti inferiore o superiore a nessuno.
Ogni sua parola è una lezione di vita e di tutte la più bella che mi porterò dietro è questa:
“I bambini dobbiamo lasciarli liberi di sognare, anche cose che sembrano impossibili, perché un giorno potrebbero diventare possibili”.
Grazie Maura, sei una grande donna. 💫⭐️✨🔭
