A large stream of meltwater (about 5 to 10 m in width) emerges from an upstream supraglacial lake in the Greenlandic ice on July, 21 2012. The darker shapes are minor streams covered by cryoconite (a mix of dust particles, soot, meteorite dust and organic material) which covers the ice sheet. Cracks cutting through the streams are visible. Along these cracks water can flow through, enlarging them and, eventually, generating moulins that can deliver meltwater through the ice.

ESA’s XMM-Newton X-ray observatory recorded 20 dust rings, 19 of which are shown here in arbitrary colors. The image merges observations made two and five days after GRB 221009A erupted. Dark stripes indicate gaps between the detectors. A detailed analysis shows that the widest ring visible here, comparable to the apparent size of a full Moon, came from dust clouds located about 1,300 light-years away. The innermost ring arose from dust at a distance of 61,000 light-years -- on the other side of our Galaxy. Image credit: ESA / XMM-Newton / M. Rigoselli, INAF.
