With the potential to image fast-moving objects.

When asked what superpowers they would like to have, many say the ability to see through things. Now, there may be a camera that could give people that gift.

Developed by Northwestern Engineering researchers, the new high-resolution camera can see around corners and through human skin and even bones. It also has the potential to image fast-moving objects such as speeding cars or even the beating heart.

The relatively new research field is called non-line-of-sight (NLoS) imaging and comes with a level of resolution so high that it could even capture the tiniest capillaries at work.

“Our technology will usher in a new wave of imaging capabilities,” said in a statement the McCormick School of Engineering’s Florian Willomitzer, first author of the study.

Happy birthday, ISS.

The first components of the International Space Station (ISS) were launched on November 20, 1998, roughly 12 years after the first Soviet MIR-2 module was launched and a full 25 years after Skylab.

The ISS took 10 years and more than 30 missions to assemble. It is the result of unprecedented scientific and engineering collaboration among five space agencies representing 21 countries: NASA (United States of America), Roscosmos (Russia), JAXA (Japan), CSA (Canada), and ESA (16 EU countries and the UK).

With fully-equipped laboratories and advanced life support systems powered by solar arrays, the ISS has space for up to seven crew members to live and work, conducting many kinds of research in low Earth orbit.

It is a lesson the U.S. space program has had to learn many times over: don’t voluntarily give up a space capability without having a successor ready to go or already operational.

But for the ISS (International Space Station), a gap in LEO (low Earth orbit) scientific research capability will likely not occur when the iconic outpost ends its career, whenever that may be.

And that is in large part due to Axiom, a private space organization with private funding that will begin adding modules to the ISS in 2024 — with the goal that those added modules will then be easily disconnected from the ISS at the end of its life, thus ensuring no gap in low Earth orbit space station capability for the United States.

Using spacecraft and ground-based facilities, Russian astronomers have inspected the Orion Bar photodissociation region, focusing on the mid-infrared emission from this source. Results of the study could help astronomers to better understand the evolution of polycyclic aromatic hydrocarbons in space. The research was published November 10 on arXiv.org.

At a distance of about 1,300 away, the Orion Nebula is the nearest of massive star formation to Earth, with a complex and extensive gas structure. It hosts the so-called “Orion Bar”—a ridge-like feature of gas and dust formed by the intense radiation from nearby, hot, young stars, which appears to be shaped like a bar.

The Orion Bar is a photodissociation region or photon-dominated region (PDR). In general, PDRs are regions in the interstellar medium (ISM) at the interface between hot ionized gas and cool molecular gas that are energetically dominated by non-ionizing ultraviolet photons.
