NASA’s James Webb Telescope Captures New Images of Jupiter’s Aurora, Rings: NPR

NASA has captured new telescope images of Jupiter showing auroras, altitude and cloud cover.
The latest photos, taken with NASA’s James Webb Space Telescopeshows bands of blue and gray in the middle, with rainbow colors at the planet’s poles.
The telescope uses a camera with three filters that can determine infrared light, invisible to the human eye, into colors on the visible spectrum.
“Honestly, we didn’t really expect it to be this good,” said planetary astronomer and UC-Berkeley professor Imke de Pater. “What’s really remarkable is that we can see details on Jupiter along with rings, small satellites and even galaxies in one image.”
The red on the photos shows the aurora, while the yellow and green show the clouds swirling around the poles. The white bands and spots indicate cloud cover, including the Great Red Spot, a massive storm that “could swallow Earth,” NASA said.
“Brightness here indicates altitude – so the Great Red Spot is foggy at high altitudes, as does the region,” said Heidi Hammel, vice president for science at the Association of Universities for Astronomical Research. equatorial region”. “Many bright white ‘spots’ and ‘strips’ may be very high-altitude cloud tops of convective storms.”
Likewise, darker areas are areas with less cloud cover. Photos with a wider angle show the rings and two moons of the planet, Amalthea and Adrastea.
