A lunar eclipse occurs when the Moon moves behind Earth and into its shadow. The reddish colour results from Earth\u2019s atmosphere scattering blue light and leaving behind red light, which bends and falls onto the Moon\u2019s surface.<\/p>\n <\/p>\n <\/p>\n Credit: Miguel Lo Bianco\/Reuters<\/p>\n<\/figcaption><\/figure>\n <\/p>\n Big. Bone.<\/b>\u00a0Palaeontologists Cecilia Apaldetti and Ricardo Mart\u00ednez stand next to a bone from what might have been the planet\u2019s largest dinosaur,\u00a0Ingentia prima<\/i>. The gigantic specimen, discovered in Argentina\u00a0and described in July<\/a>, is more than 200 million years old. It probably came from one of the earliest giant sauropods \u2014 which weighed up to 10 tonnes \u2014 and changes our understanding of how dinosaurs in this lineage grew to such immense sizes.<\/p>\n <\/p>\n <\/p>\n Credit: Michael Hutchinson<\/p>\n<\/figcaption><\/figure>\n <\/p>\n Up in the air.\u00a0<\/b>Spiders can use their silk to become airborne and float at altitudes of up to 4 kilometres \u2014 a behaviour known as ballooning. Last month,\u00a0researchers reported<\/a>\u00a0on a little-explored theory that electric currents in the air might assist, or even cause, ballooning. In experiments, they found that Linyphiid spiders (Erigone<\/i>) ballooned in response to electric fields similar in strength to those in Earth\u2019s atmosphere \u2014 suggesting that atmospheric electric fields are strong enough to provide lift, and perhaps trigger the behaviour in the first place.<\/p>\n <\/p>\n <\/p>\n Credit: Steve Lacker<\/p>\n<\/figcaption><\/figure>\n <\/p>\n Inside Brookhaven.<\/b>\u00a0This intricate image shows the Soft Inelastic X-ray Scattering (SIX) beamline at Brookhaven National Laboratory in New York state.

Dives by remotely operated vehicles have captured species such as this lizardfish, or bathysaurus, which was found hanging out at a depth of 1,771 metres, and an array of colourfully named critters: peanut worms, feather stars, cusk eels, cup corals and sea pens.<\/p>\n <\/p>\n <\/p>\n Credit: Angelos Tzortzinis\/AFP\/Getty<\/p>\n<\/figcaption><\/figure>\n <\/p>\n Blazing globe.<\/b>\u00a0Greece is one of the many places that have experienced deadly fires this summer, as temperatures hit record highs around the world.

The pictures, released this month by conservation charity ORCA, were taken in the Bay of Biscay north of Santander, Spain. Beaked whales are a group of deep-diving, toothed cetaceans that have proved incredibly elusive. This group is thought to be the largest ever sighted of the species.<\/p>\n <\/p>\n <\/p>\n Credit: Andrew Aman and David Parichy\/Univ.

In a\u00a0study<\/a>\u00a0published last month, scientists exploring the molecular pathways behind scale development released these images. They found that pathways that underlie the growth of scales, hairs and feathers are strikingly similar.

The chip detects and counts each particle it hits, and this pixel information is run through powerful algorithms to generate detailed 3D images that differentiate bones, lipids and soft tissue.<\/p>\n <\/p>\n <\/p>\n <\/p>\n<\/div>\n![\"\"](\"https:\/\/media.nature.com\/w800\/magazine-assets\/d41586-018-05858-8\/d41586-018-05858-8_15990812.jpg\")
