NASA's Webb Space Telescope has identified new clues about the surface of Pluto's largest moon.
When the International Astronomical Union announced in 2006 that Pluto was being demoted from its status as the sun's ninth planet, many astronomers and non-experts alike were shocked.
Throughout Earth's history, the planet's surface has been regularly impacted by comets, meteors, and the occasional large asteroid. While these events were often destructive, sometimes to the point of triggering a mass extinction, ...
Survey observations using the Subaru Telescope's ultra-widefield prime focus camera have revealed that there may be a population of small bodies further out in the Kuiper Belt waiting to be discovered.
Around 4 billion years ago, an asteroid hit the Jupiter moon Ganymede. Now, a Kobe University researcher has realized that the solar system's biggest moon's axis has shifted as a result of the impact, which confirmed that ...
Just how dark is deep space? Astronomers may have finally answered this long-standing question by tapping into the capabilities and distant position of NASA's New Horizons spacecraft, by making the most precise, direct measurements ...
Astronomers have discovered a planet that has the most oblong orbit ever found among transiting planets. The exoplanet's extreme circuit—which looks closer to a cucumber than a circle—follows one of the most drastically stretched-out ...
The size of the solar system is defined by the volume of space over which the sun's influence exceeds those of other nearby stars in the Milky Way galaxy. This influence derives from two fundamental forces of nature: gravity ...
Planetary scientists are proposing a new definition of a planet to replace one that many researchers view as sun-centric and outdated. The current definition—established in 2006 by the International Astronomical Union (IAU), ...
The Subaru Telescope's wide and deep imaging observations are contributing information to the New Horizons spacecraft as it moves through the outer solar system. By applying a unique analysis method to images of Kuiper Belt ...
