Hubble time! 🌌 This image features NGC 3783, a bright barred spiral galaxy about 130 million light-years from Earth, that also lends its name to the eponymous NGC 3783 galaxy group. Like galaxy clusters, galaxy groups are aggregates of gravitationally bound galaxies. Galaxy groups, however, are less massive and contain fewer members than galaxy clusters do: where galaxy clusters can contain hundreds or even thousands of constituent galaxies, galaxy groups do not typically include more than 50. The Milky Way is actually part of a galaxy group, known as the Local Group, which contains two other large galaxies (Andromeda and the Triangulum galaxy), as well as several dozen satellite and dwarf galaxies. The NGC 3783 galaxy group, meanwhile, contains 47 galaxies. It also seems to be at a fairly early stage of its evolution, making it an interesting object of study. Whilst the focus of this image is the spiral galaxy NGC 3783, the eye is equally drawn to the very bright object in the lower right part of this image. This is the star HD 101274. The perspective in this image makes the star and the galaxy look like close companions, but this is an illusion. HD 101274 lies only about 1530 light-years from Earth, meaning it is about 85 thousand times closer than NGC 3783. This explains how a single star can appear to outshine an entire galaxy! NGC 3783 is a type-1 Seyfert galaxy, which is a galaxy with a bright central region — so it’s particularly bright itself, as far as galaxies go. In this image it is recorded by Hubble in incredible detail, from its glowing central bar to its narrow, winding arms and the dust threaded through them, thanks to five separate images taken in different wavelengths of light. In fact, the galactic centre is bright enough to Hubble that it exhibits diffraction spikes, normally only seen on stars such as HD 101274. 📸 @europeanspaceagency / @hubbleesa & @NASA , M. C.

Unveiling the Horsehead Nebula’s secrets in a new light ✨ The iconic Horsehead Nebula has been captured by @esawebb in stunning detail! These new images reveal never-before-seen structures and helps us understand how light interacts with interstellar dust and gas. In this carousel we can see the Horsehead Nebula through the infrared lens of three space telescopes and four different instruments: 1. Seen by our Euclid mission, this image was captured in about one hour, which showcases the mission’s ability to very quickly image an unprecedented area of the sky in high detail. 2. @hubbleesa ’s image captures plumes of gas in the infrared and reveals a beautiful, delicate structure that is normally obscured by dust. 3. @esawebb ’s Near-InfraRed camera shows a part of the iconic nebula in a whole new light, and captures its complexity with unprecedented spatial resolution. 4. Webb’s Mid-InfraRed instrument brings the sharpest details of a section of this region of the night sky. Webb’s observations are a game-changer for understanding photon-dominated region, regions where young stars sculpt the surrounding gas and dust. This knowledge is key to unlocking the mysteries of star formation throughout the Universe! 📸 @europeanspaceagency /Euclid/Euclid Consortium/ @nasa , image processing by J.-C.

On May 11th, after dinner, @jessica_kehala (ESA doctor), Giovanni (our plumber), and I (@marco.buttu ) went outside. The temperature was -83°C with windchill, but we didn't feel the cold at all because we were so excited by the sight of the aurora. We took the picture that you see in this video. . Concordia station is located on a layer of ice and snow 3000 meters thick, in the Antarctic Plateau. This is the most extreme place in the world: 100 consecutive days without sunlight, temperatures dropping below -80°C, lack of oxygen, dry air, and no form of life. During the winter period, which lasts from February to November, the station is unreachable; we cannot receive any assistance. We are the most isolated people on the planet (along with the 13 people at the Vostok base), even more isolated than the astronauts aboard the International Space Station. The living and environmental conditions here are similar to those of a long-duration interplanetary mission; for this reason, the European Space Agency @europeanspaceagency studies us. They want to understand how the human body adapts to a quasi-extraterrestrial environment. . Giovanni on the left of the photo, Jessica in the center, me on the right in a red suit. .

Greetings skies from Brazil! I’m Phablo Araujo and in this post with @europeanspaceagency , I’m going to show you the sky of the Brazilian savannah! 🌌✨ At this time, the conditions for celestial observations in the central region of our country become excellent for months. As an astrophotographer, I take advantage of this time to venture into the surroundings of huge plantation fields and natural reserves, which allow me to photograph away from the light pollution of cities, revealing our sky with the beautiful landscapes of the Cerrado biome. It is a mix of present and past, with prehistoric cave paintings and biological phenomena such as the bioluminescence of fireflies in the ema national park, which unites heaven and Earth in a truly light show! 1 - The Milkyway core rising. 2 - A selfie with a Aquarids meteor last week. 3 - A 11k years old “astrophotography” in a cave showing the moon and possibly Venus. 4 - Jupiter over a Sunflower’s farm. 5 - The milkyway at “Formoso river”, also in Emas N. Park. 6 - The bioluminescence of fireflies larvae in termites at Emas National Park. 7 - The Andromeda Galaxy through my telescope 8 - A second stage rocket engine exhausting gases in the sky, may 8th. 9 - The Magellanic clouds. 10- The Eta Carinae nebula complex over a tree. Thanks ESA for this opportunity! 💫🌌✨ #YourESA [🇧🇷] Nesse post com a @europeanspaceagency , vou mostrar o céu da savana Brasileira! 🌌✨ Nesta época as condições de observações celestes na região central no Brasil se tornam excelentes por meses. Como astrofotógrafo, aproveito essa época para me aventurar nos arredores dos enormes campos de plantações e reservas naturais, que permitem fotografar o céu longe da poluição luminosa das cidades, revelando nosso céu com as belíssimas paisagens do bioma Cerrado. É uma mistura de presente e passado, com pinturas rupestres pré-históricas e fenômenos biológicos como a bioluminescência dos vagalumes no parque nacional das emas, que une o céu e a Terra em um show de luzes! #astronomy #astrophotography #sky #brazil #europe

Share this with the Taurus in your life ♉️ The magnificent constellation of Taurus is easy to spot in the winter sky, thanks to its two dazzling star clusters: the Pleiades, also known as the Seven Sisters, and the Hyades, which forms the Bull's face. The fiery red star Aldebaran marks the Bull's angry eye @hubbleesa has captured some interesting objects in Taurus throughout the years: 1. IRAS 05506+2414: This young, massive star shrouded in dust and gas, over 9000 light-years away, is believed to be the aftermath of an explosive event, tearing apart a young star system! Normally, young stars have swirling discs that feed them, but this one has a fan-shaped spray blasting outwards at 350 km/sec! 2. NGC 1409 & NGC 1410: A stream of material flows between two galaxies that bumped into each other 100 million years ago. The 'pipeline' stretches for over 20 000 light-years! 3. IRAS 05437+2502: The boomerang-shaped glow might be caused by a runaway young star blasting through the dust at over 200 000 km/h. 4. HH 151: This fiery jet, is a burst of material ejected by a young star. These "Herbig-Haro objects" are cosmic tantrums, blasting out at hundreds of km/second! 5. FS Tau: A super young star system, only 2.8 million years old (our Sun is 4.6 billion!). The bright object on the right, FS Tau B, is a forming star surrounded by a dusty disc that will someday be planets. This system also has jets of gas blasting out, a sign of a star's fiery youth. 6. XZ Tauri & HL Tauri: XZ Tauri is blowing a hot bubble of gas into the surrounding space, which is filled with bright and beautiful clumps that are emitting strong winds and jets. These objects illuminate the region, creating a truly dramatic scene. These images remind us that Taurus season brings grounded vibes and an appreciation for beauty, both on Earth and throughout the cosmos. 📸 @europeanspaceagency / Hubble & @NASA , R.

Hubble time! 🌌 The spiral galaxy IC 4633 is located 100 million light-years away from us in the constellation Apus. IC 4633 is a galaxy rich in star-forming activity, as well as hosting an active galactic nucleus at its core. From our point of view, the galaxy is tilted mostly towards us, giving astronomers a fairly good view of its billions of stars. However, we can’t fully appreciate the features of this galaxy — at least in visible light — because it’s partially concealed by a stretch of dark dust. This dark nebula is part of the Chamaeleon star-forming region, itself located only around 500 light-years from us, in a nearby part of the Milky Way galaxy. The dark clouds in the Chamaeleon region occupy a large area of the southern sky, covering their namesake constellation but also encroaching on nearby constellations, like Apus. The cloud is well-studied for its treasury of young stars, particularly the cloud Cha I. The cloud overlapping IC 4633 lies east of the well-known Cha I, II and III, and has been called MW9 or the South Celestial Serpent. A vast, narrow trail of faint gas that snakes over the southern celestial pole, it’s much more subdued-looking than its neighbours. It’s classified as an integrated flux nebula — a cloud of gas and dust in the Milky Way galaxy that’s not near to any single star, and is only faintly lit by the total light of all the galaxy’s stars. Hubble has no problem making out the South Celestial Serpent, though this image captures only a tiny part of it. For a showy astronomical object like IC 4633, among the South Celestial Serpent’s coils clearly isn’t a bad place to hide. 📸 @europeanspaceagency / @hubbleesa & @NASA , J.

Starburst party gone wild! ✨ @esawebb has its sights set on Messier 82, a compact galaxy throwing a starburst party! This galactic mosh pit forms stars at a whopping 10 times the rate of our own Milky Way! Webb’s infrared vision pierces the dust, revealing a hidden world: - Intricate structures: Imagine glowing filaments and stellar nurseries tucked away! - Powerful winds: These stellar winds, fueled by supernovae, sculpt the galaxy’s shape. - Clues to star formation: Understanding these winds helps scientists piece together how stars are born in such extreme environments. This research could unlock secrets about how similar galaxies in the early Universe evolved and shaped the cosmos. 📸 @NASA , @europeanspaceagency , @canadianspaceagency , @space_telescopes , A.

You won’t exercise much with this dumbbell 💨 Little Dumbbell Nebula, a favorite target for amateurs astronomers, is a planetary nebula, which is the dazzling finale of a dying star. Before collapsing into a white dwarf, the star puffed out a ring of gas and dust, sculpted by a possible binary companion that met a fiery end. The expelled material formed the beautiful lobes and central disc we see today. The scorching white dwarf, visible as a tiny dot, is 24 times hotter than our Sun. It blasts powerful winds outward at millions of kilometres per hour, sculpting the nebula and causing the gases to glow in vibrant hues. This celestial spectacle is a fleeting one - in just 15 000 years, it will vanish. Serving as a reminder of the dynamic and dramatic lives of stars. 📸 @NASA , @europeanspaceagency , @space_telescopes , A. Pagan (STScI) 📹 NASA, ESA, STScI, A. Pagan (STScI) Acknowledgment: D.

Hi all, My name is Darshna Ladva and I have the privilege of collaborating with @europeanspaceagency today. I'm a full time working mother of 2 and in my spare time (and when we have clear skies) I love to set up my telescope and or Digital camera for Deep Space, Moon, Comets, Milkyway and Planets and all things Space. I live in North West London, UK and have extremely poor light polluted skies. I have a couple of telescopes, the one I use depends on what I plan to image at the time. When my eldest child was around 6 years old he studied the solar system and we were inspired to buy him a cheap supermarket telescope to look at the Moon; I was hooked after attaching my phone and taking photos. Nearly 8 years later here I am. Producing images that I am honoured to be asked to share them; by the European Space Agency. One of my favourite things to do is to hunt Moonrises, capturing a rising Moon behind a prominent monument or foreground location is one of the most thrilling things to experience. I highly recommend trying it. You don't need much expensive equipment to try it either. Visually its one of the most magical things to witness; anyone wanting to photograph it, all you would need is a simple DSLR and a tripod if you have one (if not then somewhere to balance the camera). There are tools to work out where the Moon will rise and I am happy to help anyone who wants to try it. 😊 I also have a bit of an obsession with the Planets, still amazes me that amateurs can produce images (even with small telescopes); everytime I go out and see the planets on my screen I am awestruck. Photographing Planets does however need a bit of specialist equipment, that is readily available and surprisingly quite affordable. My equipment includes, Dslr/tripod/lens; 2 x telescopes, 2 astro cameras and a Star Tracker. I hope you like the images that I have chosen, if you would like to see more or keep in touch with any new images I create, please visit my profile at @nebuladva #youresa #spacephotography #astrophotography #telescope #moon #luna #planets #deepspace #milkyway #stars #nightsky #astronomy
