NASA’s Juno mission to Jupiter is finding the Jovian giant to be more complicated than expected. Jupiter’s magnetic field has been discovered to be much different from our Earth’s simple dipole field, showing several poles embedded in a complicated network more convoluted in the north than the south. Further, Juno’s radio measurements show that Jupiter’s atmosphere shows structure well below the upper cloud deck – even hundreds of kilometers deep. Jupiter’s newfound complexity is evident also in southern clouds, as shown in the texture and color enhanced featured image taken last month. There, planet-circling zones and belts that dominate near the equator decay into a complex miasma of continent-sized storm swirls. Juno continues in its looping elliptical orbit, swooping near the huge planet every month and exploring a slightly different sector each time around.

Milky Way Anatomy

nasa:

If we could see our galaxy, the Milky Way, from the outside, it would look like an enormous, bedazzled pinwheel. Vast sprays of stars form spiral arms that curl outward from a bright center that bulges like the yolk in a fried egg. Dark, dusty tendrils darken some regions, while glowing pink gas clouds light up others.

At the left, a face-on galaxy labeled “disk, 100,000 ly across,” has three components labeled: bar, 16,000 ly long, pointing to the bright, oblong core; spiral arms, pointing to the streams of stars that wrap around the core of the galaxy counter-clockwise; and interstellar medium, thin gas, dust, and particles between stars, pointing to a place in between the spiral arms. At the top right, an edge-on view of the galaxy looks like a CD with a ping pong ball in the middle. It’s labeled thin disk, 1,000 ly thick, pointing to the middle of the disk, and thick disk, up to 6,000 ly thick, pointing to an area slightly above the main part of the disk. The brightly glowing center is labeled bulge, contains supermassive black hole and 10 billion stars. Underneath, there are two zoomed out views of the face-on galaxy – one labeled stellar halo, 300,000 ly across has the galaxy surrounded by a faint glow. The other, labeled dark matter halo, 1 million ly across, is more zoomed out and surrounded in a mottled purple glow. Credit: NASAALT

We have a pretty good idea of the Milky Way’s overall structure, but since we’re nestled inside it, fine details are hard to see. Those clouds of gas and dust strewn throughout interstellar space block our view, especially of the far side of the galaxy.  Astronomers have used observations from different telescopes to piece together our galaxy’s anatomy. Let’s scrub up and dive in!
