Incredible images, done some years ago, of NASA’s rover Perseverance, on the surface of Mars, moving as a car in a desert. Wonderful !!!

Jupiter has also rings! like Saturn, Uranus Neptune & Chariklo… See this image taken by NASA’s Juno probe years ago, from insight to outside, with the rings of Jupiter clearly visible… It seems rings are an usual feature of planets/asteroids…

This is a very young star not far from us, the Herbig-Haro 49/50, with a more distant spiral galaxy perfectly positioned at its tip behind the Herbig-Haro object. Image by the James Webb Space Telescope‼️

A very nice and useful public observatory for pedagogical use in Sapporo, Japan. When astronomy reaches children and general public…

How many stars are there? The Double Cluster Perseus with 3 levels: 1- some bright stars in the foreground 2- the incredible double cluster, situated 7500 lightyears far 3-very dense background of stars of our MilkyWay Image: Anysllum observatory setup2: Refractor of 80mm & CMOS.

🚨: Earth is just 1 of 3.2 trillion planets in our galaxy. The sun is just 1 of 200 billion stars in the Milky Way galaxy. The Milky Way is 1 of 2 trillion galaxies in the observable universe! Need more context on how big (or small) we are?

This James Webb Space Telescope near & mid-infrared image of NGC 6072, shows an asymmetrical/multipolar shape: an evidence of a multiple star in the origin of this nebula. More info: esawebb.org/news/weic2514/

Black hole: This is a very speculative animation of a black hole consuming a star. Please dont think it is an accurate model: just it’s a nice animation for pedagogical purposes. Credit: NASA Goddard

The most massive Globular Cluster in our galaxy: Omega Centauri Formed by 10 million stars into a volume of only 150 light-years in diameter. It can be the remnant core of a small galaxy merging with the Milky Way. Image: SkyFlux Team - Leo Shatz, via APOD website.

Shiretoko National Park situated in the North of Hokaido Island is a beautiful place of extreme pristine nature. Will we see bears tomorrow? Today I watched an incredible view of lakes, a brave sea and forests… foxes & deers visited me‼️ It’s one of the World’s Heritage Sites.

Jupiter moon Callisto has a subsurface frozen/liquid ocean as other bodies (Europa, Encelado...). The Callisto's one dissipates energy due to obliquity tides. This explains its orbital inclination & eccentricity according this 2020 study: bit.ly/3mjduWQ Images: NASA

Direct images from the James Webb Space Telescope show what could be a Saturn-mass planet around Alpha Centauri. It’s in its habitable zone but a Saturn-mass planet is not suitable for human life… but what about its moons? skyandtelescope.org/astronomy-news… Artist’s concept: NASA-R.Hurt

Planet TRAPPIST-1 d has not a earth-like atmosphere according the JWST NIRSpec Spectrograph. Not detected water, methane or carbon dioxide!: go.nasa.gov/4fAFNfH Waiting a similar research about better candidates (e & f planets). Images: habitable zone & J.Olmsted picture.

Quasar S50014+81 is one of the most luminous objects known in the universe: 3 trillion suns (25000 Milky Way’s combined light!). Its black hole devours 4000 sun masses/year: buff.ly/2Lrj5Nw. Images: Right, illustration by NASA. Left, real image by Xavier Bros, Anysllum.

It is difficult to imagine what happen when two neutron stars collide, but the “new astronomy” can give us some clues: gravitational waves emission and gamma rays bursts‼️ Animation Credit: MIT & NASA Goddard Center.
