It’s been 27 years since the Hubble Space Telescope went into orbit, and the geriatric observatory is still going strong. When the telescope recently trained its sights on the solar system’s largest planet, the results were spectacular—proof that for the stellar spectator, age is but a number.
The image above is the latest picture of Jupiter. The snapshot was taken by Hubble on April 3 with the help of the telescope’s Wide Field Camera 3, a high-res instrument that lets the telescope observe using different wavelengths. It combines light on the visible, ultraviolet, and infrared spectrum to create an image of a massive planet in constant atmospheric flux.
In a press release, the European Space Agency, which co-runs Hubble with NASA, said that Hubble was able to take advantage of the planet’s current opposition with Earth to take the close-up. At the moment, Jupiter is lined up perfectly with the sun, and Earth is lined up with both the sun and Jupiter. Think of it as a truly heavenly photographic opportunity—a chance to look at the planet head-on. Better yet, Jupiter’s position relative to the sun means that it’s brighter than at any other time of year, which lets telescopes trained on the gigantic planet see even more detail than usual.
As The Washington Post’s Amy B. Wang notes, there were no new discoveries in the picture per se, but that doesn’t mean there’s nothing to look at. As ESA explains, scientists will compare the photo to previous views of the planet to hopefully learn more about the atmosphere. And for the rest of us, there’s a strangely soothing view of Jupiter’s layered cloud bands and impressive vortices.
The gas giant is thought to have sucked up most of the space debris left over after the sun formed, grabbing dust and gas with gravity. Scientists think it has two times as much debris as all of the other bodies in the solar system combined—and all of that material swirls through cloud layers in its quickly-rotating atmosphere.
Since Jupiter doesn’t exactly have a surface, it has nothing to slow the spots and vortices that appear in its atmosphere. The most famous, the Great Red Spot, is thought to have been swirling around for more than 150 years, and even though it’s unclear which gases give it that red hue, it’s the planet’s most recognizable feature. As NASA writes, the cloudiness of Jupiter’s atmosphere makes it hard to understand what might be contributing to it. But that doesn’t decrease its allure.
Want to delve even further into the mesmerizing bands of a huge planet’s atmosphere? A high-res version of the snapshot is available online. And if you prefer seeing things live, it’s a great time to check out Jupiter through in the night sky. You can find Jupiter in the east right after the sun goes down—a massive mystery that’s brighter than any star.
