Webb Observes Hidden Depths of Messier 82

Messier 82 was observed by the NASA/ESA Hubble Space Telescope in 2006, which showed the galaxy’s edge-on spiral disk, shredded clouds, and hot hydrogen gas. The NASA/ESA/CSA James Webb Space Telescope observed the core of Messier 82, capturing in unprecedented detail the structure of the galactic wind and characterizing individual stars and star clusters.

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have captured a new image of the central starburst region of Messier 82 (M82, NGC 3034 or the Cigar Galaxy), a starburst irregular galaxy located 12 million light-years away in the constellation of Ursa Major. Messier 82 was observed by the NASA/ESA Hubble Space Telescope in 2006, which showed the galaxy’s edge-on spiral disk, shredded clouds, and hot hydrogen gas. The NASA/ESA/CSA James...

This image shows Arp 72, a galaxy pair that includes NGC 5996 (large spiral galaxy) and NGC 5994 (its smaller companion, in the lower left of the image). The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS) and the Dark Energy Camera (DECam), which is mounted on NSF’s Víctor M. Blanco 4-m telescope at Cerro Tololo Inter-American Observatory in Chile. Four filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / L. Galbany / J. Dalcanton / Dark Energy Survey / DOE / FNAL / DECam / CTIO / NOIRLab / NSF / AURA.

Structure of SOT spin-LED: controlling the intensity of emitted light and charge current is the basis of transferring and processing information; by contrast, robust information storage and magnetic random-access memories are implemented using the spin of the carrier and the associated magnetization in ferromagnets; the missing link between the respective disciplines of photonics, electronics and spintronics is to modulate the circular polarization of the emitted light, rather than its intensity, by electrically controlled magnetization; Dainone et al. demonstrated that this missing link is established at room temperature and zero applied magnetic field in light-emitting diodes through the transfer of angular momentum between photons, electrons and ferromagnets.

Jörges et al. tackled the question of whether body posture influences human perception of self-motion and distance; they found some evidence that the same amount of optic flow can elicit the sensation of having traveled further when supine versus when sitting upright, that is, optic flow is more effective at eliciting a sense of self-motion when supine; this constitutes evidence that visual and non-visual cues are at least partially integrated even when self-motion is presented only visually; however, they did not find any significant differences between performance on Earth and in the microgravity of the ISS, suggesting that vestibular cues play a minor role, if any, in the estimation of visually presented self-motion.
