Mars and Saturn Are Truly Spectacular in These Hubble Telescope Views

This summer, Mars and Saturn have come pretty close to Earth — and NASA's Hubble Space Telescope has captured every magnificent detail.

On July 27, Mars reached opposition, roughly aligning with the Earth and the sun. Just a few days later, in the early hours of Tuesday (July 31), Mars reached the closest point to Earth in its orbit. The Red Planet remains bright and especially visible in the night sky, as does Saturn. Saturn also reached opposition and came close to Earth this summer.

The proximity of Saturn and Mars has given Hubble the unique opportunity to take especially detailed images of the two planets. Space.com caught up with Bonnie Meinke, a project scientist for the James Webb Space Telescope at the Space Telescope Science Institute in Baltimore, Maryland, to talk about both planets making a close approach to Earth and the incredible work that Hubble does in capturing events like this one.

Meinke presented some of Hubble's most spectacular images of Mars and Saturn at opposition in the video. In time-lapsed images of Saturn, you can see the planet's rings, several of its moons, and, because it's summer right now, you can see huge storm clouds in Saturn's northern hemisphere circling the planet's northern pole.

In a similar time lapse of Mars that Meinke displayed, you can clearly see the planet's moons Phobos and Deimos. What's perhaps even more spectacular, you can also see the global dust storm that encapsulates and swirls around the Red Planet.

Despite the clarity of the image, Mars almost looks blurry, because it is covered in a layer of dust. In the video, Meinke shows a Hubble image of Mars from 2016 for comparison, where you can see more of the planet's surface features.

These two images from the Hubble Space Telescope show how much the 2018 global dust storm has obscured features on the planet. Both images were taken during opposition, and in the 2016 image, it was a cloudy day on Mars. Still, it is obvious how much more the planet's surface features stand out in that image versus the image from 2018 when the whole planet is encapsulated in dust.

Meinke described a number of other incredible cosmic moments that Hubble has captured over the years. She included Hubble's years of observing the Great Red Spot on Jupiter and how Hubble has shown in vivid detail how this spot is shrinking. Meinke also showed the movement of Neptune's large clouds.

"Hubble's really become a weather satellite for our solar system," Meinke said.  

Meinke also spoke about some of the unexpected finds that Hubble has made over the years. She noted Hubble's images of plumes that were found coming from Europa and interesting storm structures on Jupiter. Meinke stated that these images can give "us a better perspective of how storms happen and evolve on our own planet. And we can keep an eye on the entire solar system to see things change and evolve with time."
