This stunning spherical image manages to cram in the entire universe, including our Solar System at the centre. The mind-boggling image also packs in the outer planets, Kuiper belt, Oort cloud, Alpha Cetauri star and the cosmic web along with the Milky Way galaxy, Andromeda galaxy and other nearby galaxies
The Hubble telescope has captured an image of an unusual edge-on galaxy, revealing remarkable details of its warped dusty disk and showing how colliding galaxies spawn the formation of new generations of stars. The dust and spiral arms of normal spiral galaxies, like our own Milky Way, appear flat when viewed edge-on. This Hubble Heritage image of ESO 510-G13 shows a galaxy that, by contrast, has an unusual twisted disk structure, first seen in ground-based photographs.
This mosaic image of Andromeda spiral galaxy -- showing explosive stars in its interior and cooler, dusty stars forming in its many rings -- combines observations from the Herschel Space Observatory taken in infrared light (the orange hues), and the XMM-Newton telescope captured in X-rays (the blues). Andromeda is our nearest large neighbor -- located about 2.5 million light-years away and holds nearly trillion stars. Our Milky Way galaxy contains about 200 - 400 billion stars.
