Light is the most energy-efficient way of moving information. Yet, light shows one big limitation: it is difficult to store. As a matter of fact, data centers rely primarily on magnetic hard drives. However, in these hard drives, information is transferred at an energy cost that is nowadays exploding. Researchers of the Institute of Photonic Integration of the Eindhoven University of Technology (TU/e) have developed a ‘hybrid technology’ which shows the advantages of both light and magnetic hard drives.

Ultra-short (femtosecond) light pulses allows data to be directly written in a magnetic memory in a fast and highly energy-efficient way. Moreover, as soon as the information is written (and stored), it moves forward leaving space to empty memory domains to be filled in with new data. This research, published in Nature Communications, promises to revolutionize the process of data storage in future photonic integrated circuits.

This menagerie includes three spiral-shaped galaxies, an elliptical galaxy, and a lenticular (lens-like) galaxy. Somehow, these different galaxies crossed paths in their evolution to create an exceptionally crowded and eclectic galaxy sampler.

Caught in a leisurely gravitational dance, the whole group is so crowded that it could fit within a region of space that is less than twice the diameter of our Milky Way.

The latest Planetary Science Decadal Survey has been published. The future mission recommendations include a Uranus orbiter in the mid-2040s (the first visit to the planet since 1986) and the Enceladus Orbilander (landing in the early 2050s).

NASA’s Perseverance Mars rover used its Mastcam-Z camera system to shoot video of Phobos, one of Mars’ two moons, eclipsing the Sun. It’s the most zoomed-in, highest frame-rate observation of a Phobos solar eclipse ever taken from the Martian surface.

Several Mars rovers have observed Phobos crossing in front of the Sun over the past 18 years. Spirit and Opportunity made the first observations back in 2004; Curiosity in 2019 was the first to record video of the event. Each time these eclipses are observed, they allow scientists to measure subtle shifts in Phobos’ orbit over time. The moon’s tidal forces pull on the deep interior of the Red Planet, as well as its crust and mantle; studying how much Phobos shifts over time reveals something about how resistant the crust and mantle are, and thus what kinds of materials they’re made of.

The iconic Hubble Space Telescope observed five galaxies locked in a gravitational dance, before eventually merging together, just before its 23nd anniversary.

In the sparse collection of atoms that fills interstellar space, Voyager 1 has measured a long-lasting series of waves where it previously only detected sporadic bursts.

Starlink, part of Elon Musk’s space company, aims to provide broadband to airlines as it pushes to reach business clients.

Remote work is expanding into many other areas besides office work. Robots and remote-control technology make a greater range of tasks possible, from stocking convenience stores, to operating heavy machinery and even serving as a labor force in space. A key advantage of remote-controlled robots is that they do not require the kind of complex programming found in automated robots, such as industrial robots that work in factories. This means that remote-controlled robots are more flexible, easily adapting to work that cannot be programmed. Greater use of this technology can allow robots to take over dangerous and exhausting work, subsequently helping to deal with labor shortages and improve work environments. In this episode, we’ll look at the forefront of remote robotics, and see examples of how this technology could transform work.
