NASA’s Curiosity Mars Rover Starts Unpacking Boxwork Formations

The rover recently drilled a sample from a new region with features that could reveal whether Mars’ subsurface once provided an environment suitable for life. New images from NASA’s Curiosity Mars rover show the first close-up views of a region scientists had previously observed only from orbit. The images and data being collected are already […]

NASA’s MAVEN Makes First Observation of Atmospheric Sputtering at Mars

After a decade of searching, NASA’s MAVEN (Mars Atmosphere Volatile Evolution) mission has, for the first time, reported a direct observation of an elusive atmospheric escape process called sputtering that could help answer longstanding questions about the history of water loss on Mars.

NASA’s Dragonfly Mission Sets Sights on Titan’s Mysteries

When it descends through the thick golden haze on Saturn’s moon Titan, NASA’s Dragonfly rotorcraft will find eerily familiar terrain. Dunes wrap around Titan’s equator. Clouds drift across its skies. Rain drizzles. Rivers flow, forming canyons, lakes and seas. But not everything is as familiar as it seems.

Webb’s Titan Forecast: Partly Cloudy With Occasional Methane Showers

Saturn’s moon Titan is an intriguing world cloaked in a yellowish, smoggy haze. Similar to Earth, the atmosphere is mostly nitrogen and has weather, including clouds and rain. Unlike Earth, whose weather is driven by evaporating and condensing water, frigid Titan has a methane cycle.

NASA’s Webb Reveals New Details, Mysteries in Jupiter’s Aurora

NASA’s James Webb Space Telescope has captured new details of the auroras on our solar system’s largest planet. The dancing lights observed on Jupiter are hundreds of times brighter than those seen on Earth. With Webb’s advanced sensitivity, astronomers have studied the phenomena to better understand Jupiter’s magnetosphere.

Eye on Infinity: NASA Celebrates Hubble’s 35th Year in Orbit

In celebration of the Hubble Space Telescope’s 35 years in Earth orbit, NASA is releasing an assortment of compelling images recently taken by Hubble, stretching from the planet Mars to star-forming regions, and a neighboring galaxy.

Planet Sizes and Locations in Our Solar System

Our solar system has eight planets, and five officially recognized dwarf planets. Which planet is biggest? Which is smallest? What is the order of the planets as we move out from the Sun? This is a simple guide to the sizes of planets based on the equatorial diameter – or width – at the equator […]

NASA’s Webb Captures Neptune’s Auroras For First Time

Long-sought auroral glow finally emerges under Webb’s powerful gaze For the first time, NASA’s James Webb Space Telescope has captured bright auroral activity on Neptune. Auroras occur when energetic particles, often originating from the Sun, become trapped in a planet’s magnetic field and eventually strike the upper atmosphere.

NASA’s Curiosity Rover Detects Largest Organic Molecules Found on Mars

Researchers analyzing pulverized rock onboard NASA’s Curiosity rover have found the largest organic compounds on the Red Planet to date. The finding, published Monday in the Proceedings of the National Academy of Sciences, suggests prebiotic chemistry may have advanced further on Mars than previously observed.

Planetary Alignments and Planet Parades

On most nights, weather permitting, you can spot at least one bright planet in the night sky. While two or three planets are commonly visible in the hours around sunset, occasionally four or five bright planets can be seen simultaneously with the naked eye. These events, often called “planet parades” or “planetary alignments,” can generate […]
