New Method Aids Search for Dazzling Alien Worlds:

mindblowingscience:

A group of astronomers is using a new method to search for hard to spot alien planets: By measuring the difference between the amount of light coming from the planets’ daysides and nightsides, astronomers have spotted 60 new worlds thus far.

The Colorful Clouds of Rho Ophiuchi : The many spectacular colors of the Rho Ophiuchi clouds highlight the many processes that occur there. The blue regions shine primarily by reflected light. Blue light from the star Rho Ophiuchi and nearby stars reflects more efficiently off this portion of the nebula than red light. The Earths daytime sky appears blue for the same reason. The red and yellow regions shine primarily because of emission from the nebulas atomic and molecular gas. Light from nearby blue stars – more energetic than the bright star Antares – knocks electrons away from the gas, which then shines when the electrons recombine with the gas. The dark brown regions are caused by dust grains – born in young stellar atmospheres – which effectively block light emitted behind them. The Rho Ophiuchi star clouds, well in front of the globular cluster M4 visible here on the upper right, are even more colorful than humans can see – the clouds emits light in every wavelength band from the radio to the gamma-ray. via NASA

Swirls of Jupiter

Jupiter is a very stormy, turbulent, violent planet. The planet completes a day (or one complete rotation) within roughly 10 hours, which creates massive winds, producing these swirls, and violent storms. The fast rotation coupled with the fact that the planet is nothing but gas greatly multiplies the Coriolis effect. Earth too has a Coriolis effect, this creates the characteristic hurricane shapes and also contributes to the fact that storms will spin the opposite direction in different hemispheres. Luckily, our rotation is slower – our storms are less frequent and less violent than they would be if our days were shorter.

The above images come from the recent Juno mission by NASA.

Multi-planet System Found Through Crowdsourcing

A system of at least five exoplanets has been discovered by citizen scientists through a project called Exoplanet Explorers, part of the online platform Zooniverse, using data from NASA’s Kepler space telescope. This is the first multi-planet system discovered entirely through crowdsourcing.

Thousands of citizen scientists got to work on Kepler data in 2017 when Exoplanet Explorers launched. It was featured on a program called Stargazing Live on the Australia Broadcasting Corporation (ABC). On the final night of the three-day program, researchers announced the discovery of a four-planet system. Since then, they have named it K2-138 and determined that it has a fifth planet – and perhaps even a sixth, according to the new paper.

Another batch of 2017 Kepler data was recently uploaded to Exoplanet Explorers for citizen scientists to peer through. Astronomers have not yet searched through most of it for planets.
