An  exoplanet  or extrasolar planet is a planet outside the Solar System. The first possible evidence of an  exoplanet  was noted in 1917, but was not recognized as  ... ‎ This is a list of   exoplanets . As of 21 August 2019, there are 4,043 confirmed   exoplanets . The majority of these planets were discovered by the Kepler space ... All of the planets in our solar system orbit around the Sun. Planets that orbit around other stars are called  exoplanets . Exoplanets are very hard to see directly with telescopes. They are hidden by the bright glare of the stars they orbit.  So, astronomers use other ways to detect and study these distant planets. They search for exoplanets by looking at the effects these planets have on the stars they orbit. An artist's representation of Kepler-11, a small, cool star around which six planets orbit.

30 Years Ago: Voyager 2's Historic Neptune Flyby 30 Years Ago: Voyager 2's Historic Neptune Flyby Thirty years ago, on Aug. 25, 1989, NASA's Voyager 2 spacecraft made a close flyby of Neptune, giving humanity its first close-up of our solar system's eighth planet. Marking the end of the Voyager mission's Grand Tour of the solar system's  four giant planets  - Jupiter, Saturn, Uranus and Neptune - that first was also a last: No other spacecraft has visited Neptune since. "The Voyager planetary program really was an opportunity to show the public what science is all about," said Ed Stone, Voyager's project scientist since 1975. "Every day we learned something new." Wrapped in teal- and cobalt-colored bands of clouds, the planet that Voyager 2 revealed looked like a blue-hued sibling to Jupiter and Saturn, the blue indicating the presence of methane. A massive, slate-colored storm was dubbed the "Great Dark Spot," similar to...

Brazil Government being critisized for poor performance to put out current fires in Amazon Region by other Government around the world Latest Amazon Fires in South America NASA's AIRS Maps Carbon Monoxide from Brazil Fires New data from NASA's Atmospheric Infrared Sounder (AIRS) instrument, aboard the Aqua satellite, shows the movement high in the atmosphere of carbon monoxide associated with fires in the Amazon region of Brazil. This time series maps carbon monoxide at an altitude of 18,000 feet (5,500 meters) from Aug. 8-22, 2019. As the series progresses, the carbon monoxide plume grows in the northwest Amazon region then drifts in a more concentrated plume toward the southeastern part of the country. Each "day" in the series is made by averaging three days' worth of measurements, a technique used to eliminate data gaps. Green indicates concentrations of carbon monoxide at approximately 100 parts per billion by volume (ppbv); yellow, at about 120 ppbv; a...
