The 60-ton, 2.7-metre-long Hoba meteorite in Namibia is the largest known intact meteorite. Supernova explosions like this one, captured in NGC 4526, are a source of neutrinos (Credit: NASA/ESA). SDO | Solar Dynamics Observatory. Adriano Anfuso/Vikas Chander The elliptical galaxy NGC 474 (lower right) contains many shell structures and tidal tails formed by past interactions with other galaxies. The galaxy is currently interacting with neighboring spiral galaxy NGC 470 (left). Lenticular galaxy NGC 467 (left) is the background galaxy, more than twice as far away. The imagers used a 24-inch telescope to collect data over 20 hours. Vaonis Vespera Pro - Advanced Smart Telescope. Cloud Appreciation Society.
