Evidence Builds for the Existence of Mysterious “Planet 9”

NASA JPL October 04, 2017 It might be lingering bashfully on the icy outer edges of our solar system, hiding in the dark, but subtly pulling strings behind the scenes: stretching out the orbits of distant bodies, perhaps even tilting the entire solar system to one side. If a planet is there, it’s extremely distant and will stay that way ... Read More »

Kepler Mission Verifies 1,284 New Exoplanets

NASA May 10, 2016 NASA’s Kepler mission has verified 1,284 new planets – the single largest finding of planets to date. “This announcement more than doubles the number of confirmed planets from Kepler,” said Ellen Stofan, chief scientist at NASA Headquarters in Washington. “This gives us hope that somewhere out there, around a star much like ours, we can eventually ...

Cassini Finds Titan’s Highest Mountain

NASA JPL March 24, 2016 In a nod to extraterrestrial mountaineers of the future, scientists working on NASA’s Cassini mission have identified the highest point on Saturn’s largest moon, Titan. Titan’s tallest peak is 10,948 feet (3,337 meters) high and is found within a trio of mountainous ridges called the Mithrim Montes. The researchers found that all of Titan’s highest ... Read More »

Scientists Find a Possible Ninth Planet in Our Solar System

NASA January 21, 2016 Caltech researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune (which orbits the sun ...

Newly Discovered Planet is Like Jupiter in Its Infancy

NASA August 14, 2015 One of the best ways to learn how our solar system evolved is to look at younger star systems in the early stages of development. Recently, a team of astronomers including NASA scientists discovered a Jupiter-like planet within a young system that could serve as a decoder ring for understanding how planets formed around our sun. ...

Finding Other Earth-like Planets

NASA JPL July 23, 2015 image: The discovery of a super-Earth-sized planet orbiting a sun-like star brings us closer than ever to finding a twin of our own watery world. But NASA’s Kepler space telescope has captured evidence of other potentially habitable planets amid the sea of stars in the Milky Way galaxy. image: To take a brief tour of ... Read More »

Water is Everywhere in the Cosmos

NASA April 7, 2015 As NASA missions explore our solar system and search for new worlds, they are finding water in surprising places. Water is but one piece of our search for habitable planets and life beyond Earth, yet it links many seemingly unrelated worlds in surprising ways. “NASA science activities have provided a wave of amazing findings related to ...

Planet Found With Four Parent Stars

March 4, 2015 NASA JPL — Astronomers have discovered the second known case of a planet residing in a quadruple star system. — The planet was known before, but was thought to have only three stars, not four. — The findings help researchers understand how multiple star systems can influence the development and fate of planets. Growing up as a ... Read More »

New Weather Map of Exoplanet is Most Detailed Ever

ESA/Hubble October 9, 2014 A team of scientists using the NASA/ESA Hubble Space Telescope have made the most detailed map ever of the temperature of an exoplanet’s atmosphere, and traced the amount of water it contains. The planet targeted for both of the investigations was the hot-Jupiter exoplanet WASP-43b. WASP-43b is a planet the size of Jupiter but with double ... Read More »

Size of Alien Super-Earth Precisely Measured

NASA JPL July 23, 2014 Thanks to NASA’s Kepler and Spitzer Space Telescopes, scientists have made the most precise measurement ever of the radius of a planet outside our solar system. The size of the exoplanet, dubbed Kepler-93b, is now known to an uncertainty of just 74 miles (119 kilometers) on either side of the planetary body. The findings confirm ... Read More »
