Findings will help scientists understand the chemistry, dynamics, and evolution of the atmospheres of Venus and Earth.

NGC 1365 in infrared light helps astronomers understand the complex flow of material within the galaxy and how it affects the reservoirs of gas from which new stars can form.

Scientists have used more than 2,000 images to create the first long-term study of Titan's weather.

Scientists think wind-driven processes can add strong oxidizers to the atmosphere, which could soak up methane more rapidly.

Scientists believe Phobos may have formed from re-accretion of impact debris.

Scientists found that at a certain point in venusian history, the high temperatures caused a partial mobilization of the crust, leading to an efficient cooling of the mantle.

Comet 103P/Hartley promises to be the brightest comet of 2010 when it peaks in October.

These maneuverable spacecraft could ship huge amounts of data back to Earth, overcoming the problem of downloading such quantities from traditional orbiters.

The data reveal that two distinct populations of asteroids or comets barraged Earth's satellite early on in its history.

The new models are based on the idea that the collapsing star itself is not spherelike, but distinctly asymmetrical and affected by a host of instabilities in the volatile mix surrounding its core.

The Lunar Reconnaissance Orbiter (LRO) is turning its attention to scientific research and will continue to map the Moon for 2 to 4 more years.

Research suggests a star once thought to be in its youth is actually an old red giant that recently consumed a nearby sun or giant planet.

An unusually close Jupiter will make September's opposition especially memorable. Astronomy magazine's podcast, video, and interactive star chart can help all levels of observers enjoy this great event.

Scientists have discovered 14 new trans-Neptunian objects by culling the data archives of the space telescope.

The innermost planet reaches greatest western elongation September 19.

These extremely compact star cities discovered by citizen scientists appear to have low amounts of complex elements after being diluted by streams of gas and strong supernova winds.

The ratio of oxygen and carbon dioxide isotopes found on the Red Planet suggests that liquid water primarily existed at temperatures near freezing and that hydrothermal systems similar to Yellowstone's hot springs have been rare throughout the planet's past.

An analysis of tidal interactions between planets and their host stars provides a potential explanation why scientists failed to detect exoplanets in star clusters like 47 Tucanae.

The findings suggest that a supernova sprayed a mass of finely grained particles into the cloud of gas and dust that gave birth to the solar system 4.5 billion years ago.

Scientists are using these findings to refine the Jupiter collision rate, which appears to be more frequent than previously thought.
