Jupiter may be the undisputed king of the planets in the solar system, but its record of 79 moons has just been smashed after the announcement of a stunning 20 new outer moons at Saturn.
Previously thought to have 62 moons, the discovery puts the ringed planet's new total at a peerless 82 moons.
Announced Monday by the International Astronomical Union's Minor Planet Center, all 20 are outer moons about three miles/five kilometers in diameter.

Which Planet has the Most Moons? What are the Most Livable ...-moons If you've been pondering about which planet has the most moons, then, look no further. Among its accolades, Jupiter has the enviable title of harboring the highest number of moons of the solar system. With an impressive 79 moons, Jupiter's moons are so many that only 53 moons have been named. The remaining 26 are currently awaiting official names.!! Studying these moons can reveal information about their

Which Planet Has the Most Moons? | Space Questions Answered ...-moons While we only have a single moon, other planets have many more than us. Saturn has as 62 confirmed moons, but that does not compare to Jupiter , which has a total of 69 known moons. Jupiter has the most moons of any planet in the Solar System. Of the 69 moons, only 53 of them have been named. That means 16 moons have yet to be named.!! The observing team included Sheppard, David Jewitt of UCLA, and Jan Kleyna of the University of Hawaii.

A Churning 'Molten Blob' of Planet May Be Easier to Find. Here's Why. | Space
The smaller a planet , the more difficult it is to spot — which is frustrating for scientists hoping to find Earth-like worlds.
That's why a team of researchers set out to determine what planetary traits would make a world a little easier to identify! Planets With The Most Moons - WorldAtlas.com www.worldatlas.com /articles/ planets ...The planet with the most moons is Jupiter . Jupiter has a total of 67 moons. Experts agree that natural satellites were formed out of the same process that formed primary astronomical bodies such as planets.!! Their analysis suggests that molten worlds with atmospheres full of water or carbon dioxide will be more easily observed by instruments that will be available to scientists soon.
* * *
And that's a boon for observers: If two planets have the same mass but one has a magma ocean and the other doesn't, it could be about 5% larger across, making it easier to spot. And a molten world is more likely to be leaking water and carbon dioxide from that liquid rock out into a developing atmosphere.
Those two molecules are easily released by molten rock, but they are also the sort of thing that future telescopes like NASA's James Webb Space Telescope are being designed to detect! Which Planet Has the Most Oxygen? - WorldAtlas.com www.worldatlas.com /articles/ ...-oxygen.html That planet is earth and thus has the highest amount of oxygen among the planets. Mercury and Mars have traces of oxygen in their atmospheres as well. However, just because these planets, or any other unknown celestial bodies, have traces of oxygen does not mean that they are capable of human inhabitation.!! Webb won't be able to study Earth-size planets around stars like our sun, but it should be able to analyze those around smaller M dwarf stars.
Most Extreme 'Hot Jupiter' Alien Planet Completes 1 Orbit Every 18 Hours | Space
Giant alien worlds known as hot Jupiters get scorchingly close to their host stars, and now astronomers have discovered the most extreme version of such planets to date — one that zips around its star in a little more than 18 hours, a new study finds.
This exoplanet's orbit is likely decaying enough for scientists to actually measure it over the coming decade, researchers added.
In the past two decades or so, astronomers have confirmed the existence of more than 4,000 worlds outside of Earth's solar system! Which Planet Has The Most Moons? Stunning New Discovery ...www.forbes.com ...An artist's conception of the 20 newly discovered moons orbiting Saturn . These discoveries bring the planet's total moon count to 82, surpassing Jupiter for the most in our Solar System.!! These discoveries have revealed that some of these exoplanets , such as hot Jupiters, gas giants that orbit their stars closer than Mercury does the sun, are very different from those seen in Earth's solar system.

Lava Flows on Venus Suggest That the Planet Was Never Warm and Wet - Universe Today
Venus is often referred to as " Earth's sister planet ", owing to the number of similarities between them. Like Earth, Venus is a terrestrial (aka. rocky) planet and it resides with our Sun's Circumstellar Habitable Zone (CHZ). And for some time, scientists have theorized that billions of years ago, Venus had oceans on its surface and was habitable – aka. not the hot and hellish place it is today.
However, after examining radar data on the Ovda Fluctus lava flow , a team scientists at the Lunar and Planetary Institute concluded that the highlands on Venus are likely to be composed of basaltic lava rock instead of granite. This effectively punches a hole in the main argument for Venus having oceans in the past, which is that the Ovda Regio highlands plateau formed in the presence of water.
The study that describes their findings (and includes a new map of the highlands plateau) recently appeared in the Journal of Geophysical Research: Planets . The study was conducted by members of the LPI with the assistance of undergraduate student intern Frank Wroblewski (from Northland College), and Prof. Tracy K.P. Gregg of the University of Buffalo.
'Impossible' exoplanet and an alternate planet-formation theory | Space | EarthSky
The discovery of exoplanet GJ 3512b – a planet “too big for its star” – adds fuel to the competition between 2 theoretical models of how planets form. It suggests many more Jupiter-like planets are waiting to be found, orbiting nearby sunlike stars.
Notice the spiral structure here? This isn’t a galaxy; it’s a computer simulation of a newly forming solar system. It’s part of the disk instability model of how planets form, a model that’s been less accepted by astronomers – until now. A new discovery suggests this model may be correct. If so, Jupiter-like worlds may be common around nearby sunlike stars. Image via astronomical theorist Alan Boss/ Carnegie Science .
Boss’s new work is supported by a September 27, 2019, paper, published in the peer-reviewed journal Science , reporting on the discovery of a new exoplanet labeled GJ 3512b . This confirmed, massive, Jupiter-like planet orbits a very low-mass red dwarf star. And thus this planet – sometimes called the planet that shouldn’t exist – belies the previously most-popular theory of planetary formation, which had suggested it was impossible for such a massive planet to form around such a small star.
