Gill | › It has winds that howl at the speed of sound, a 3,000-degree-Fahrenheit (1,600-degree-Celsius) day side, and a pitch-black night side where temperatures are cooler, but still a sizzling 1,000 degrees Fahrenheit (540 degrees Celsius). Lightning will occur on all cloudy exoplanets that harbor a substantial atmosphere; hence, lightning will leave chemical tracers in these atmospheres, at least for a certain amount of time.”Earth’s Global Electric Circuit is thought to affect the weather on large and on global scales, says Helling. Part of the southern hemisphere was dubbed "Storm Alley" by scientists on NASA's Cassini mission because of the frequent storm activity the spacecraft observed there. And while their experiments yielded plenty of complex carbohydrate molecules, including amino acids, she says today, their experiment is considered to be more reminiscent of volcanic plumes than early Earth's atmosphere.Even so, Helling remains confident that astronomers will eventually detect lightning on an extrasolar planet.I'm a science journalist and host of Cosmic Controversy (I'm a science journalist and host of Cosmic Controversy (Opinions expressed by Forbes Contributors are their own.I cover aerospace, astronomy and host The Cosmic Controversy Podcast. It’s raged for at least 300 years, but In the 20th century, three smaller ovals merged to form the Little Red Spot, about half the size of its larger cousin. To date more than 4000 exoplanets have been detected and among those numerous super-earth and … To the human eye, the sky would appear hazy and reddish or butterscotch colored because of all the dust suspended in the air.Dust will be an issue for future missions to Mars as well. As for the astrobiological significance of lightning on a terrestrial mass exoplanet?“Lightning will only matter for astrobiology if we know the planet well,” said Helling.“We would need to know the chemical composition of the atmosphere.”The planet’s location inside the extrasolar system would likely determine its cloud cover and its atmospheric dynamics, says Helling. [citation needed] Volcanic lightning may have sparked life on Earth. Separated from the four inner planets by the Asteroid Belt, the four outer planets dwarf the inner four. Related Questions.

Jupiter has vast storms and we can pick up the radio noise from its lightning.

They do not have rocky surfaces the way Mercury, Venus, Earth and Mars do. Let’s take a tour of some of the unusual storms in our solar system and beyond. all have lightning!!!! “Do they exist in exoplanets, too? Lightning on Venus -- as well as on any other planet -- is an important discovery because the electrical discharges drive the chemistry of an atmosphere by breaking molecules into fragments that can then join with other fragments in unexpected ways. With no solid surface to slow them down, Jupiter's spots can survive for many years.Saturn has one of the most extraordinary atmospheric features in the solar system: a Storm chasers would have a field day on Saturn. cloud-free, ’fair weather’) regions in an atmosphere, she notes.

Scientists hoped to see the storms again, but both had vanished. Mercury, the planet nearest the Sun, is scorching hot, with daytime temperatures of more than 800 degrees Fahrenheit (about 430 degrees Celsius). When Voyager 2 flew by in 1986, it spotted few clouds. Their atmospheres have very different compositions to what we know from our own solar system, she says. Of these, the planets Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune have significant atmospheres. The findings could also give clues to life on other planets.

Scientists now think new storms crop up on Neptune every four to six years, with each storm lasting up to six years.Discovered in 2011, WASP-43b is located 260 light-years away.

Dr. Lori Glaze These are just two points which would have to be considered when analyzing the effects of lightning on such a planet, she says.In the 1950s biochemists Stanley Miller and Harold Urey conducted laboratory spark experiments to try and replicate the effect of lightning on an atmospheric gas, says Helling. At least one storm chased itself: In 2010 and 2011, scientists witnessed a storm that churned its way around the planet until it Earth isn’t the only world in our solar system with bodies of liquid on its surface.

Lightning is a naturally occurring electrostatic discharge during which two electrically charged regions in the atmosphere or ground temporarily equalize themselves, causing the instantaneous release of as much as one gigajoule of energy. It also has weak gravity — only about 38% of Earth's — making it hard for Mercury to hold on to an atmosphere.Its barely there atmosphere means Mercury doesn’t have dramatic storms, but it does have a strange "weather" pattern of sorts: it’s It also has magnetic “tornadoes” — twisted bundles of magnetic fields that connect the planet’s magnetic field to space. But there are other god/planets that astrologers have associated with this phenomenon.
