26 milioni di galassie compongono il primo bottino scientifico raccolto da ESA's Euclid mission, lanciato meno di 2 anni fa dall' European Space Agency per sondare i misteri del lato sconosciuto dell'universo, ossia della materia e dell'energia oscure che lo occupano per il 95% ansa.it/canale_scienza…

The first patchwork images from the Euclid space telescope have captured 26 million galaxies, some as far off as 10.5 billion light years. Learn more: newscientist.com/article/247189…

In the recently released Euclid Deep Field North, we spot the Cat’s Eye Nebula. Located around 3000 light-years away, this dying star is shedding its outer colourful shells. Explore more hidden treasures in the #ESAEuclid mosaics 👉 esa.int/Science_Explor…

One of the things that we can (and will) do with edge-on disks is to compare dark matter- and modified gravity-based models. Differences between the two scenarios are maximised here, because lensing probes projected mass, which is much more flattened in disks than for halos.
