Space & Universe

The starlight from Andromeda is 2.5 million light years away and so appears extremely dimly to us on earth. In order to make it appear bright like this we have to use very long exposures, minutes, hours, maybe days even to capture enough light. But when we do that we also capture all the light from things that are nearer. If you do that on a moonlit night the sky would literally be white and you wouldn’t be able to pick out any objects in the sky because of the bright white of the sky. 🌌 At 140,000 light years across, it’s 40% bigger than our 100,000 light year diameter Milky Way. If the whole galaxy were bright enough, this is what you’d see at night. (Not to perfect scale and with the moon as a reference) The only galaxy which we can see with our naked eyes, the Andromeda. Andromeda is the closest large galaxy to us! 🌎 Do you love Moon & Andromeda ❤️

Classifying Knowledge! What can we add?

Perhaps there could be other Universes, with different versions of ourselves, different histories and alternate outcomes, than our own. Around 13.7 billion years ago, simply speaking, everything we know of in the cosmos was an infinitesimal singularity. Then, according to the Big Bang theory, some unknown trigger caused it to expand and inflate in three-dimensional space. As the immense energy of this initial expansion cooled, light began to shine through. Eventually, the small particles began to form into the larger pieces of matter we know today, such as galaxies, stars and planets. One big question with this theory is: are we the only universe out there? With our current technology, we are limited to observations within this universe because the universe is curved and we are inside the fishbowl, unable to see the outside of it (if there is an outside.)

From the past to the present: a celestial evolution revealed! Witness the transformative beauty of the Ring Nebula through time. 🌌✨

Some interesting facts.

The Hubble Space Telescope captured GAL-CLUS-022058s, a rare Einstein ring, in the Fornax constellation. Nicknamed the "Molten Ring," it's one of the largest and most complete examples. The ring's shape is due to gravitational lensing, where light from a distant galaxy is bent by the gravity of a closer galaxy cluster. This phenomenon makes it an ideal subject for studying distant galaxies. Credit: ESA/Hubble & NASA, S. Jha; Acknowledgement: L. Shatz

This image is one of the most photogenic examples of the many turbulent stellar nurseries the NASA/ESA Hubble Space Telescope has observed during its 30-year lifetime. The portrait features the giant nebula NGC 2014 and its neighbour NGC 2020 which together form part of a vast star-forming region in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, approximately 163 000 light-years away.
