Aurorae and Lightning on Jupiter : Why does so much of Jupiter’s lightning occur near its poles? Similar to Earth, Jupiter experiences both aurorae and lightning. Different from Earth, though, Jupiter’s lightning usually occurs near its poles – while much of Earth’s lightning occurs near its equator. To help understand the difference, NASA’s Juno spacecraft, currently orbiting Jupiter, has observed numerous aurora and lightning events. The featured image, taken by Juno’s Stellar Reference Unit camera on 2018 May 24, shows Jupiter’s northern auroral oval and several bright dots and streaks. An eye-catching event is shown in the right inset image – which is a flash of Jupiter’s lightning – one of the closest images of aurora and lightning ever. On Earth (which is much nearer to the Sun than Jupiter), sunlight is bright enough to create, by itself, much stronger atmospheric heating at the equator than the poles, driving turbulence, storms, and lightning. On Jupiter, in contrast, atmospheric heating comes mostly from its interior (as a remnant from its formation), leading to the hypothesis that more intense equatorial sunlight reduces temperature differences between upper atmospheric levels, hence reducing equatorial lightning-creating storms. via NASA
Great post
Hello. Imagine a meadow.
Now, look closer. There. Enjoy @mushiniwa’s aesthetic insects traversing leaves, petals, and fingertips: nature in its tiny places.
@lindagoesmushrooming and takes excellent photos of the ones she encounters. Step into Linda’s office.
@happy-geology takes pictures of empty places, whether it’s the moon, the earth’s crust, or a calm forest, there simply are no humans. Bliss.
@nature-hiking also enjoys the vast and empty spaces, which, when you think about it, aren’t really that empty at all, are they?
Great!
Northern Winter Night : Orion always seems to come up sideways on northern winter evenings. Those familiar stars of the constellation of the Hunter are caught above the trees in this colorful night skyscape. Not a star at all but still visible to eye, the Great Nebula of Orion shines below the Hunter’s belt stars. The camera’s exposure reveals the stellar nursery’s faint pinkish glow. Betelgeuse, giant star at Orion’s shoulder, has the color of warm and cozy terrestrial lighting, but so does another familiar stellar giant, Aldebaran. Alpha star of the constellation Taurus the Bull, Aldebaran anchors the recognizable V-shape traced by the Hyades Cluster toward the top of the starry frame. via NASA
