By extension, could intelligence be observed on a much … Read more
Neptune is the eighth planet from the sun in our solar system. This blue gas giant is far larger than Earth, at more than 17 times Earth’s mass and nearly 58 times Earth’s volume, according to NASA. Neptune’s rocky core is surrounded by a slushy fluid mix of water, ammonia and methane ice. Astronomer Galileo … Read more
Jupiter is the largest planet in the solar system, named after the king of the gods in Roman mythology. The gas giant Jupiter is a stormy enigma, wrapped in colorful clouds whipped by strong winds that sweep below circles of rings and moons.

Mars is a parched planet ruled by global dust storms. It’s also a frigid world, where night-time winter temperatures fall to minus 140 C (minus 220 F) at the poles. But it wasn’t always a dry, barren, freezing, inhospitable wasteland. It used to be a warm, wet, almost inviting place, where liquid water flowed across … Read more
Jupiter has finally been observed spitting out X-rays in high-energy wavelengths. Emanating from the giant planet’s permanent auroras, and detected by NASA’s space-based X-ray telescope NuSTAR, the emissions are the most energetic light seen coming from any planet in the Solar System (aside from Earth). The detection could shed light on the most powerful … Read more

The sun’s nearest neighbor may actually host three planets, a new study reports. Astronomers have found evidence of a third planet circling Proxima Centauri, a red dwarf star that lies a mere 4.2 light-years from our solar system. The candidate world, known as Proxima d, is estimated to be just 25% as massive as Earth, … Read more

What appears to be a teeny tiny alien world has just been found orbiting the Solar System’s closest stellar neighbor. The exoplanet candidate, named Proxima d, orbits a star named Proxima Centauri: a small, dim red dwarf star just 4.2 light-years from the Sun. Amazingly, the exoplanet is just a quarter of the mass … Read more
