What happens when a new technology is so precise that it operates on a scale beyond our characterization capabilities? For example, the lasers used at INRS produce ultrashort pulses in the femtosecond range (10-15s) that are far too short to visualize. Although some measurements are possible, nothing beats a clear image, says INRS professor and ultrafast imaging specialist Jinyang Liang.

Commercial photographer Levon Biss typically shoots portraits of world-class athletes—sports players caught in motion. His new series however, catches subjects that have already been paused, insect specimens found at the Oxford Museum of Natural History. The series originally started as a side-project capturing the detail of bugs that his son would catch at home, and is now displayed at the museum in an exhibition titled Microsculpture.
During the course of his selection from the museum’s collection Biss rejected more than 99% of the bugs he came across, only choosing those that were of the right size and color. To capture these subjects in such immense detail, each part of the insect required a completely different lighting setup.

In a press release on February 22, 2017, NASA announced the discovery of the most Earth-sized planets found in the habitable zone of a single star, called TRAPPIST-1. This system of seven rocky worlds–all of them with the potential for water on their surface–is an exciting discovery in the search for life on other worlds. There is the possibility that future study of this unique planetary system could reveal conditions suitable for life.
In February 2018, closer study of the seven planets suggested that some could harbor far more water than the oceans of Earth, in the form of atmospheric water vapor for the planets closest to their star, liquid water for others, and ice for those farthest away. The new study pinned down the density of each planet more precisely, making TRAPPIST-1 the most thoroughly known planetary system apart from our own.

When the Huygens probe dropped into Titan’s atmosphere January 14, 2005, no one knew what to expect. Would it splash down into a methane ocean? Sink into a tar pit? Crash into sharp rocks or tumble off a ravine? And, most importantly, what manner of world lurked beneath Titan’s thick shroud of haze and clouds?
For landings on Mars or the Moon, mission scientists plotted out landing sites with meticulous care. Telescopes and orbiters scanned the ground, imaging dangerous terrain and safe zones, and flight engineers pored over their maps and planned accordingly.
