Meget stort og meget småt
Vi skal en tur ud i rummet. Denne timelapse-video af instruktøren Sriram Murali bevæger sig på lidt under tre minutter fra den californiske storby San José til Death Valley i Mojaveørkenen. I hver scene er der lidt mindre ‘forurening’ fra urbaniseringens kunstige belysning. Sidste scene sætter sådan set alt i perspektiv. Skru evt. ned for lyden, hvis det bliver for new age-agtigt.
Og så går vi lige den anden vej uden at forlade verdensrummet. Videnskabsfolk på California Institute of Technology har genskabt van Goghs maleri ‘Starry Night’ ved at folde DNA-molekyler. Samme teknologi vil en dag kunne bruges til at bygge mikroskopiske biosensorer, som kan hjælpe os med at holde dumme sygdomme fra livet.
A hand out image made available by the European Southern Observatory on August 24 2016 show an image created from pictures forming part of the Digitized Sky Survey 2 of the sky around the bright star Alpha Centauri AB also shows the much fainter red dwarf star, Proxima Centauri, the closest star to the Solar System. The blue halo around Alpha Centauri AB is an artifact of the photographic process, the star is really pale yellow in colour like the Sun. Scientists on August 24, 2016 announced the discovery of an Earth-sized planet orbiting the star nearest our Sun, opening up the glittering prospect of a habitable world that may one day be explored by robots. Named Proxima b, the planet is in a "temperate" zone compatible with the presence of liquid water - - a key ingredient for life. / AFP PHOTO / EUROPEAN SOUTHERN OBSERVATORY / Davide De Martin/Mahdi Zamani / RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO / EUROPEAN SOUTHERN OBSERVATORY/ DAVIDE DE MARTIN MAHDI ZAMANI- NO MARKETING NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTS
