On August 2. 1st, millions of Earthlings will gather to watch as a total solar eclipse sweeps across the centerline of the United States over the course of 9. For many, itll be once in a life time spectacle. But if you had a spacecraft on hand, you wouldnt need to wait decades for the next total solar eclipse to arrive at a town near youyou could simply jet off to Mars, Jupiter, Saturn, or even Pluto. Thats because theres a veritable zoo of solar eclipses occurring all across our solar system, all the time. To be fair, none of these extraterrestrial eclipses is quite like the total solar eclipse here on Earth, where a quirk of celestial geometry causes the Moon to stack perfectly over the Sun, leaving a fiery ring of coronal jets to illuminate the sky. Some satellites, like Mars moon Phobos, are too small to engulf the Sun from the perspective of an observer on the planet, resulting in what astronomers call a transit. In other cases, like that of Saturns moon Titan, the angular size of the satellite in the sky is far greater than that of the Sun, resulting in a solar occultation. But thats just the basicseclipses, it turns out, come in all shapes and sizes, and studying them can tell us a lot about our cosmic neighborhood. Tiny transits at Mars. For most other planets, we have to imagine what a solar eclipse would look like from the surface or, in the case of a gas giant, the cloud tops. But when it comes to Mars, weve actually seen quite a few. In 2. 00. 4, NASAs Spirit and Opportunity rovers captured six solar transits events from the surface of Marsfour involving the potato shaped moon Phobos, another two starring the even runtier satellite Deimos. They were, according to a paper published in Nature the following year, the first direct images of satellites transiting the Sun from the surface of another planet.

According to Mark Lemmon, an astronomer at Texas A M University and co investigator on the Spirit and Opportunity rovers, early solar eclipse observations helped NASA refine the positions of Mars moons in the sky. Despite observing Phobos and Deimos for 1. Earth, theyre small and far away, Lemmon told Gizmodo.

Once eclipse observations had improved the orbits of the two moons, the European Space Agencys Mars Express Orbiter was able to point its camera accurately enough to capture high res images of both, Lemmon said. Eclipse watching on Mars has only gotten better, especially since NASAs Curiosity rover landed in Gale Crater in August 2. SecurityStudy. On August 21st, millions of Earthlings will gather to watch as a total solar eclipse sweeps across the centerline of the United States over the course of 90 minutes. Working with headphones on usually means youd rather not be bothered, but sometimes it means youre just listening to something while you work. If you want to be. Just look at this footage Curiosity captured in 2. Phobos racing across the Sun, transforming our beloved star into an eerie cyclops monster over the course of 3.

Even though Spirit and Opportunity refined the positions of Mars moons more than a decade ago, theres still plenty we can learn by watching their transits. Even now, while theres no missing where Phobos and Deimos are, their orbits are changing all the time due to the push and pull of gravity, from Mars, Lemmon explained. In particular, Phobos raises a tiny tide on Marsa slight displacement of the rock surface, which in turn leads to a gravitational pull on Phobos, changing its orbit. That is why Phobos is spiraling in toward Mars and will eventually be destroyed. Indeed, eclipses may be critical to figuring out how soon Phobos faces annihilationand when Deimos will be cast away into deep space. Hazy eclipses at Saturn. With. 62 confirmed moons, Saturns skies offer myriad eclipse viewing opportunities, from tiny solar transits to massive occultations to moons stacked atop other moons. But of all the gas giants many satellites, few produce an eclipse as otherworldly as Titan, a massive methane cauldron that challenges our understanding of the kinds of places life might emerge. It was the Voyager 1 spacecraft that spotted the first solar occultation at Titan in 1. The Astrophysical Journal. As Titan swept across the Sun, Voyager captured some of the light that filtered through its hazy atmosphere, which scientists used to confirm that the moons skies are composed mostly of nitrogen. Since NASAs Cassini probe arrived in orbit around Saturn in 2. Titan eclipses, which weve used to probe the chemistry of the moons thick haze. Some of what weve learned even has implications for understanding planets beyond our solar system. In 2. 01. 4, analyzing visible and infrared spectra collected by Cassini during solar occultations, researchers demonstrated that Titan absorbs, refracts, and scatters sunlight in ways that may obscure information about deeper parts of the atmosphere. This, the researchers wrote in a paper published in PNAS, could have ramifications for elucidating the atmospheres of exoplanets, particularly super Earths. Haze has a dramatic effect on the transit spectra, the researchers wrote, noting that it substantially impacts the amount of information that can be gleaned. This information could prove incredibly useful when the James Webb Space Telescope starts peering into the atmospheres of distant planets over the next few years. But as valuable at the science is, astronomers are mostly drawn to Saturnian eclipses because of their sheer beauty. In most cases, we imaged eclipses because they are just wondrous events, at Saturn as they are on Earth, Cassini imaging lead Carolyn Porco told Gizmodo. It was part of my desire, from the very beginning of the Cassini mission, to turn our image taking responsibilities at Saturn into a video documentary of everything there was to see there, including celestial motion. The rare, 4. Uranus. Solar eclipses are a fairly common for Jupiter and Saturn, but not so for Uranus, a planet which, in flagrant defiance of celestial convention, circles our Sun tipped over on its side, its spin axis almost perfectly aligned with its orbital plane. Because of Uranus funky tilt, its poles are alternately illuminated during its 8. Sun. The moons, which circle Uranus in the band of rings stretched across the planets equator, only align edge on with the Sun ever 4. Ice Giant. Rare, but not impossible to catch. Kawneer Architectural Manual. In 2. 00. 6, just as Uranus was approaching its summer equinox, the Hubble Space Telescope caught a never before seen glimpse of the moon Ariel traversing the face of the ice giant and casting a shadow, or umbra, on the planets blue green cloud tops. From the surface of Uranus, it would have looked like a solar eclipse. These observations were planned only to study the atmosphere of Uranus the detection of Ariel and its shadow were purely serendipitous, Heidi Hammel, Executive Vice President of AURA, who helped analyze the image while working at the Space Science Institute, told Gizmodo.
