Astronomers have imaged a new world of a young Jupiter in unprecedented details, using the Gemini Observatory's new Planet Imager (GPI). They discovered the planet's mass is about twice the Jupiter's, and it seems the planet is the most Solar System-like pla
Dwarf planet Ceres continues to fascinate scientists with it’s pyramid like mountain and bright spots on its surface. NASA’s Dawn spacecraft, the first probe to reach this dwarf planet on March 6, 2015, continues to return images and other data of this
Lying near the asteroid rich abyss between Mars and Jupiter high above our Solar System, a unique family of space rocks called Euphrosyne asteroids just got discovered by the scientists at NASA's Jet Propulsion Laboratory (JPL).The Euphrosynes are distributed at the
New enhanced-color images from NASA's Cassini spacecradr revealed unexplained arc-shaped, reddish streaks on the surface of Saturn's icy moon Tethys. The red arcs are narrow, curved lines on the moon's surface, and are among the most unusual color features o
Today, physicist Wal Thornhill continues his discussion of NASA’s New Horizons mission to the dwarf planet Pluto. The mission has already provided a number of surprises for planetary scientists.The tiny planet’s geological activity, its apparent age, the stu
A new study of young Istok crater led by Tjalling de Haas of Utrecht University in the Netherlands reveals that Mars, a planet of paradoxes, may have had a climate that resembles that of our own in the recent past.Istok crater, located in the Aonia Terra region of Mars,
A previous Picture of the Day published in late 2012 quoted Jonathan Nichols from the University of Leicester:“The main aurora oval on Jupiter we think should dim when the solar wind blows harder, but what we see is that actually gets brighter, which is totally
After NASA's New Horizons spacecraft suffered an anomaly on July 4, which caused temporary loss of communications, mission control announced today the spacecraft is healthy and it continues on its course toward Pluto for a historic July 14 flyby.Contact with the spa
Having found no potential threats on the way, NASA's New Horizons spacecraft stays course to Pluto, as it speeds closer to it's historic July 14, 2015 flyby of Pluto and it's five moons. Launched from Cape Canaveral on January 19, 2006, New Horizons woke up
Scientists working for the ESA's Venus Express mission have recently presented the best evidence yet for existence of active volcanoes on planet Venus. Previous radar missions have revealed Venus to be covered in volcanoes and lava flows and it is long assumed that
