We are now in the Virgo cluster of galaxies: An incredible chain of galaxies, the Markarian’s Chain with… how many galaxies? Image taken using the second setup of the Anysllum Observatory, a telescope R80 with 11 hours of LRGB exposure. #cielosESA @AstroSabadell.

Galaxies around NGC 7331, 40 million lightyears far. The main one is an unbarred spiral with a diameter of 120000 lightyears as the MilkyWay. Image by Xavier Bros & @jaume_zapata -@Astrosabadell- from the "Anysllum" observatory. Today it is visible a bright supernovae there‼️.

A Double Detonation Supernova‼️ The first explosion acts like a detonator for the second in this supernova remnant: 0509-67.5. A two-star system creates a shock wave that goes both out and in and so triggers a full Type Ia Supernova near the center. Credit: ESO via Apod website.

The exoplanet Kepler-447b orbits a G type star similar to our sun. It’s a giant planet (about 165% of Jupiter) composed mainly of gas. When it transits in front the star we see it only 0.004 magnitudes fainter! This tiny gap has been detected from the Anysllum Observatory. Wow‼️

A black hole is a region of spacetime where gravity is so strong that nothing can escape from it. The boundary of no escape is called the event horizon. Illustration: ESO

The largest volcano and mountain in the entire solar system, Olympus Mons, is located in Mars. It is 25 km high!! with a diameter about the same size as France‼️ Images: aminoapps.com

The birth of a supermassive black hole? This Infinity galaxy image by JWST shows two very compact, red nuclei, each surrounded by a ring: the collision of two disk galaxies. A young black hole is in between the two nuclei, within a vast expanse of gas: go.nasa.gov/4nQiwdo

Moon crater Clavius imaged with a webcam. It's also the crater where humans have an important facility in the film "2001 Space Odyssey"…

Marie Curie: “Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.”

This is not a comet! Mercury has a 2.5 million km long tail. The solar wind and micro-meteorites eject sodium atoms from Mercury’s surface. This creates a yellow-orange tail of sodium gas only visible with a 589nm filter and specially good conditions. Images: S. Voltmer

Since a lot of people are confused about what this is, every telescope here is owned by a person. Each person can log in remotely to use their telescope to capture photos of space from our dark skies!

Hoy en #cielosESA... @Xavi_Bros nos envía esta espectacular imagen del cúmulo de galaxias en Virgo. La increíble cadena de Markarian. ¡Muchas gracias @Xavi_Bros por tu foto! Etiqueta tus 📸📸 con #cielosESA

NGC 7469: A galaxy with an incredible star birth rate & an active galactic nucleus -an extremely bright central region of a galaxy that is dominated by the light emitted by dust and gas as it falls into a black hole: ow.ly/rinE50Wfnsa Image: JWST - L. Armus, A. S. Evans

What are the 25 brightest stars in our night sky? See here them in true color with their IAU-recognized names. Where is the famous Polaris? In fact is not between the 25 brightest stars‼️ These wonderful images were done by Tragoolchitr Jittasaiyapan via APOD website.

Bodies in the Universe: Small asteroid -> Asteroid/comet -> dwarf planet -> planet -> brown dwarf -> dwarf red star -> medium star -> giant star -> supergiant star… It’s more a CONTINUUM than a categorial organization! Image: Wikipedia

The new interestelar object A11pl3Z imaged few hours ago by the @AstroSabadell member Ramon Naves. Astrometry done! Wonderful‼️
