The Rosette Nebula is a large region powered mainly by the radiation and stellar winds from hot, massive O and B type stars, causing both the nebular gas to ionize and excite emitting specific spectral lines, and the collapse for new star formation. Photo Credits: Greg Polanski
Robo-Glove was developed by NASA and GM to reduce workers' stress injuries and provide extra gripping force to operate tools through actuated artificial tendons. Pressure sensors in the fingertips provide feedback to the control system regulating the level of motors' actuation.
This is Mars' Olympus Mons obtained by the Mars Express satellite and processed. The solar system's largest known volcano is about 620 km in base diameter and 21.9 km tall. Low-viscosity lava flows that solidified gave it its shield shape and formed a layered structure over time.
This video shows an Euler's disk gradually losing its rotational energy as a result of friction with the platform surface, air, and even within the disk itself. The energy is primarily converted into heat and sound waves energy.
This is Arp 273 by Hubble, a pair of galaxies gravitationally interacting with each other. It is thought that these galaxies already encountered in the past, and that their mutual tidal influences affected their structures, also leading to enhanced star formation activity sites.
Soli is a miniature radar technology developed by Google ATAP with the goal of recognizing hand gestures. The system emits radio waves and captures the portion reflected back phase shifted. The signals are processed and fed into machine learning models for gesture classification.
This is table salt magnified and processed under an electron microscope. At the atomic level the arrangement of sodium cations and chloride anions is mostly regular and symmetric, forming a particularly stable crystal lattice structure governed by the electrostatic force.
The Fighting Dragons of Ara is an emission nebula found about 4000 light years away. High-energy radiation and stellar winds primarily from hot young stars ionize the interstellar gas, emitting light when atoms transition to lower-energy states. Image Credit: Astrophotocologne
Velox is a robot capable of swimming through water and crawling over ice, snow, sand and other grounds using a coordinated system of actuators powering soft, undulating fins, granting biomimetic properties reminiscent of the animal kingdom. Video Credit: Pliant Energy Systems
