For the first time, astronomers have spotted a faint galaxy right behind the thick dust curtain of our Galaxy. This patch of sky is obscured, like a window caked with sand and smoke, but heat rays invisible to the eye (infrared light) allowed us to peer through the barrier. The images revealed a tiny star system, resembling a blurry dwarf cloud — previously it just wasn't noticed. Precise brightness measurements confirmed it's a real galactic disk, not a distant gas blob. Previously, only bright objects were seen behind the cosmic dust and gas; now a whole hidden population is opening up. Perhaps hundreds of such galaxies are lurking there, and finding them will help map the invisible dark matter — the framework of the cosmos. A striking detail: the same dust that sets up the veil also serves as raw material for planets and new suns in the Milky Way. The curtain that hides distant worlds weaves our own reality as well. To determine the distance, we need light analysis and a measure of its reddening from the expansion of the Universe — then we'll know which stage of evolution we've caught.
Nearly 20% of the sky is hidden from us by the Milky Way's dust — like a whole forest of galaxies behind an impenetrable screen.
Just like in Yefremov's novel 'Andromeda Nebula,' where heroes push through cosmic dust to uncharted worlds.
