Also, I'll probably never be able to draw jumpship sails in proper scale, as those are supposed to be, like, kilometers wide. It's a massive disk with a barely-visible pencil of a ship in vague proximity to it.

(🇮🇹 nel primo commento😊) 🇬🇧 Let's go back to talk about the physics phenomenon of radiation pressure! (I'm referring to my second post😉) When a comet comes near a star it starts releasing gases in a process called outgassing. This produces a visible "coma" and sometimes a tail: the one we see in every single comet representation 🌠 This coma feels a force exerted by the star's radiation pressure, that causes the formation of a tail oriented in a way that it always points away from the star. It may feel a little counterintuitive but the tail does not "follow" the path of the comet but stays radial to its orbit around the star! This is because the pressure of the star's radiation literally pushes the particles of the coma and tail away (#socialdistance at its finest guys, the tail can reach a length of 3.8 astronomical units!!). Here I chose to show you the beautiful C/2019 Y4 (or ATLAS Y4), a comet discovered on December 28 2019 that fragmented on April 9. Swiping left instead you can watch a little animation about the behaviour of the tail of a comet! - Credit:ATLAS, Wiki - #physics #astrophysics #solarsail #spacecraft #spacemission #esa #nasa #eso #solarsystem #earth #space #popularscience #popscience #popsci #science #comet #atlasy4 #atlas #comettail #radiationpressure #orbit #star #sun https://www.instagram.com/p/B-9NdB9pAIG/?igshid=utezxqisplpa

The Astroknights came about when I tried to combine the two coolest things: Astronauts and swords.

Testing Sunjammer Solar sail, it is a term defined by science fiction short story “Sunjammer” whose writer is Arthur C. Clarke in his 1964. In his story, he named Sunjammer is a method of powering small spacecraft without the use of an expensive propellant. It is a method for the propellant-free population and is quickly carving out space in the future of spaceflight. For testing a new type of solar sail system NASA has teamed up with NanoAvionics which run the mission by NASA’s Ames Research Center called Advanced Composite Solar Sail System (ACS3) in Silicon Valley. It is a small satellite move to low Earth orbit with a solar sail that unfolds around 800 square feet. The mission ASC3 will work to replace rocket propellants by developing and testing newly designed solar sails by using sunlight beams to give the nanosatellite velocity. NASA is an old technology, has thrown a solar test before in the year 2011. It is the second attempt of a flight test called Sunjammer that was canceled in 2014. The Planetary Society of Non-profit scientific organizations flew its own crowd-funded solar spacecraft last year. The NanoAvinic’s who have designed and constructed a 12U bus at its Columbia and according to research news Testing Sunjammer Solar Sail NASA. NASA’s Langley Research Center in Hampton, Virginia is also participating in the project. A Solar Sail is basically just like a sailing ship from the old clipper ships. You see in the movies but instead of the physical wind, a solar sail in space is a sail that reflects sunlight. People don’t realize as the light reflects from you it’s actually pushing on you and that’s because light doesn’t have rest mass but it does have momentum. When demonstrated, sun based sail innovation could empower a large group of adaptable space missions. Including flying a propelled space climate cautioning framework to all the more rapidly and precisely ready satellite administrators and utilities on Earth of geomagnetic storms brought about by coronal mass discharges from the sun. The innovation additionally could help expel a portion of the in excess of 8,000 bits of orbital dispatch refuse and jetsam ringing the planet. Lead station-keeping activities, or float at high scopes above Earth for correspondences and perception; and drive an assortment of fuels, profound space investigation, and gracefully shipping missions. They give a slight push to it. If you stick a light enough and big enough metallic sail near the sun, away from Earth’s gravity it’s going to move. The object gets closer to the sun, it gets a lot more push from a sail and if the object cut the distance in half, it will go half away toward the sun from the earth. From the initial push, the object moves faster than a rocket. The fact that light pushes objects has been known for quite some time but the fact that it could be used for propelling a spacecraft. It discovered until the Marine missions which were a bunch of probes in the 60s. F Brent Abbott CEO of NanoAvionics North America said: “I’m very happy & excited that NanoAvionics will be a part of Nasa’s effort. Eventually leading to more marvelous deep-space missions following the first interplanetary CubeSats Marco-A and B (Mars Cube One). The solar sail teamed up with NanoAvionics will build. Its system at new Columbia in Illinois with the final integration to be done under Nasa Ames facilities. Read the full article

🇬🇧 (🇮🇹 in the first comment) I'm three days late (but I'm Italian so nobody's surprised) but here it is... The amazing image that was presented one year ago to the world on April 10!! Isn't it beautiful?? 😍 As you probably know this is a "picture" of the black hole in the galaxy M87, taken by elaborating data from the Event Horizon Telescope (EHT). But how do you see something that by definition does not emit light?! Well it's not easy and it took the collaboration of scientist from literally all over the world, but as you can see it can be done. This is not a picture taken by a normale camera... It's not even taken by a very big and expensive telescope! What scientists did here is amazing. They created a network of radiotelescopes (EHT as we called it) and used a technique for imaging of far away objects known as Very Long Baseline Interferometry (VLBI.. We LOVE weird names😉). What happens with this method is that many little telescopes point to the same object and focus at the same time, acting as a giant virtual telescope that can gather much more light with a very high resolution. In this way you have a powerful instrument by merging many smaller ones! Amazing, have I already said it? 🤔 - Credit: ESO - #physics #astrophysics #solarsail #spacecraft #spacemission #esa #nasa #solarsystem #earth #space #popularscience #popscience #popsci #science #eht #eventhorizontelescope #eso #esa #nasa #scientist #radiotelescope #telescope #blackhole #m87 #galaxy https://www.instagram.com/p/B-7HodTplRx/?igshid=qtemt6essz0

🇬🇧First English, a seguire in italiano! 🇮🇹 🇬🇧This is a period of anniversaries so I'm going to talk about Yuri Alekseyevich Gagarin (Юрий Гагарин). 51 years ago he was the first human to journey into outer space in his capsule: Vostok 1. He was a Soviet Air Force Pilot and was 34 when he completed his mission. What not many people know is that the mission with the Vostok 1 was his only one, even if he served as a backup crew to the Soyuz 1 mission, that ended in a tragic crash. His only flight lasted 1 hour and 48 minutes and gave him fame and success, bringing him to become deputy training director of the Cosmonaut Training Centre. The first picture in this post was taken by me in June 2019 at the London Science Museum, where there was an exhibition celebrating 50 years from the Moon Landing😊🚀🌕 🇮🇹 Oggi cade l'anniversario della missione Vostok 1, dove il cosmonauta Yuri Alekseyevich Gagarin passò 1 ora e 48 minuti orbitando nello spazio attorno la nostra bella Terra. Gagarin era un pilota dell'aviazione dell'Unione Sovietica 3 questa missione lo rese così famoso che fu la sua unica, anche se fu chiamato come membro di scorta per la missione, finita in tragedia, Soyuz 1. Infatti dopo la sua epica impresa fu chiamato ad addestrare al Centro Addestramento Cosmonauti fuori Mosca, che prese il suo nome in seguito alla sua morte. La prima foto del post è una foto che ho scattato io nel giugno scorso al Museo della Scienza di Londra. Infatti c'era una esibizione temporanea per celebrare i 50 anni dall'allunaggio 😊🚀🌕 #physics #astrophysics #solarsail #spacecraft #spacemission #esa #nasa #solarsystem #earth #space #popularscience #popscience #popsci #science #yurigagarin #firstcosmonaut #fka #rka #firstspacejourney #ЮрийГагарин https://www.instagram.com/p/B-39OdCJbAq/?igshid=tb9ufcvy7cc1
