Space scientists just found a pair of Saturn-like planets that have the heat on high.

The two worlds orbit the star TOI-216 in the constellation Dorado, 580 light years away. That’s unfathomably far from Earth—approximately three-and-a-half quadrillion miles.

Though official confirmation awaits, researchers say theyre virtually certain both are out there.

“We’re very, very confident this is a real planetary system,” says David Kipping, assistant professor of astronomy at Columbia University and the lead author of the study.

Scientists made the discovery after analyzing data from TESS, the space telescope launched by NASA last April.

The outer planet—TOI-216c—is about the size of Jupiter or Saturn, the two largest planets in our solar system.

The inner planet—TOI-216b—is slightly smaller, “between the size of Saturn and Neptune,” says Kipping.

Their star is similar to our Sun, though about 15 percent smaller and cooler.

Although the scientists are calling the worlds “warm Saturns,” there’s a caveat. “Warm” does not mean balmy, temperate, or Earth-like. The inner planet registers over 600 degrees Fahrenheit; the outer one, 440 F.

Life existing on either of them—at least life as we know it—is a fanciful notion at best.

“Its a little bit on the warm side for that,” notes Kipping.

Another caveat: the comparison to Saturn has nothing to do with rings.

Instead, both planets are “puffy, like Saturn,” Kipping says, “with a low density.” Large as they are, they’re lighter than Earth, and gaseous, not rocky.

Other worlds, more hospitable, might hide nearby; the system could be a plum place for exomoons.

That’s particularly intriguing to Kipping, one of astronomys foremost exomoon hunters. The two warm Saturns—enormous—“are exactly the type of planets” to have satellites, he says.

Indeed, in our solar system, the large planets have lots of moons. Like Saturn, with 62.

Also, the worlds orbit their star in a “two-to-one resonance,” says Kipping.

TOI-216b makes a revolution every 17 days. TOI-216c takes 34, exactly twice as long.

That resonance is a clue that the system is relatively serene, Kipping says, not one “with a violent history.”

Such a scenario is good for moons.

“If there are moons around those things, they almost certainly would have survived up to this day,” he says.

As with other TESS sightings, further observations of both planets is a given.

Not so with the worlds detected by the Kepler Space Telescope, predecessor to TESS; most of Keplers discoveries are too dim and distant to do follow-up. “It‘s difficult to learn much more about them,” says Kipping.

But TESS, viewing 85 percent of the sky, is pointing at the closest, brightest stars. Already, the probe has identified 365 objects of interest. Many will prove bogus, cosmic phenomena masquerading as planets. Yet some will pan out. Over two years, TESS might find 20,000.

With that, the next generation of space telescopes—like NASA’s James Webb—will have viable targets. Those new missions will try to discern the details of the TESS worlds. They will measure atmospheres and look for satellites; they will search for signs of alien life.

“These are the planets,” says Kipping, “that we will study for the next 100 years.”

The external world– TOI-216 c– has to do with the size of Jupiter or Saturn, the 2 biggest worlds in our planetary system.

Their star resembles our Sun, though about 15 percent smaller sized and cooler.

Life existing on either of them– a minimum of life as we understand it– is a fanciful concept at finest.

” It s a bit on the warm side for that,” keeps in mind Kipping.

Another caution: the contrast to Saturn has absolutely nothing to do with rings.

Rather, both worlds are “puffy, like Saturn,” Kipping states, “with a low density.” Big as they are, they’re lighter than Earth, and gaseous, not rocky.

TOI-216 b makes a transformation every 17 days. TOI-216 c takes 34, precisely two times as long.

That resonance is an idea that the system is fairly peaceful, Kipping states, not one “with a violent history.”

Such a circumstance benefits moons.

” If there are moons around those things, they probably would have endured approximately this day,” he states.
