Astronomers Reveal Brown Dwarfs and Stars Share Formation Process

Using the Very Large Array, an international team of astronomers has discovered jets of material ejected by still-forming young brown dwarfs, revealing the first direct evidence that brown dwarfs are produced by a scaled-down version of the same process that produces stars. The astronomers studied a sample of still-forming brown dwarfs in a star-forming region […]

Cassini Spots Unusual Red Arcs on Icy Saturn Moon

Enhanced-color images from NASA’s Cassini spacecraft reveal unexplained reddish arcs 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 on Saturn’s moons to be revealed by Cassini’s cameras. Images taken using clear, green, infrared and ultraviolet spectral […]

New HiRISE Image of the Northern Plains of Mars

This new image from NASA’s Mars Reconnaissance Orbiter shows frost in gully alcoves in a crater on the Northern plains of Mars. Seasonal frost commonly forms at middle and high latitudes on Mars, much like winter snow on Earth. However, on Mars most frost is carbon dioxide (dry ice) rather than water ice. This frost […]

Researchers Believe An Interior Ocean May Be Driving Geologic Activity on Pluto

Scientists believe that the ice flows and water ice mountains revealed by New Horizons help support the idea that an interior ocean may be driving geologic activity on Pluto. Pluto wears its heart on its sleeve, and that has scientists gleaning intriguing new facts about its geology and climate. Recent data from NASA’s New Horizons […]

Mars Orbiter Preparing for Mars Lander Arrival

NASA’s Mars Reconnaissance Orbiter is preparing for the arrival of NASA’s InSight Lander, which will occur on 2016. A planned 77-second firing of six intermediate-size thrusters on July 29 will adjust the orbit timing of the veteran spacecraft so it will be in position to receive radio transmissions from InSight as the newcomer descends through […]

NASA's Dawn Reveals Topography on the Surface of Dwarf Planet Ceres

New color-coded maps of dwarf planet Ceres reveal a diverse topography with height differences between crater bottoms and mountain peaks as great as 9 miles (15 kilometers). Scientists continue to analyze the latest data from Dawn as the spacecraft makes its way to its third mapping orbit. “The craters we find on Ceres, in terms […]

Astronomers Find Molecular Oxygen

Newly published research from the Harvard-Smithsonian Center for Astrophysics provides the first self-consistent treatment of preshock, shock, and postshock regions under the influence of UV fields, and explains why O2 detections are so rare. Oxygen is the third most abundant element in the universe (after hydrogen and helium) and of course it is important: all […]

Hubble Image of a Spiral Galaxy in the Coma Cluster

A newly published study from Yale University gives astronomers a clearer view of how powerful cosmic winds can blow through galaxies, sweeping out interstellar material and stopping future star formation. A Yale University analysis of one such event in a nearby galaxy provides an unprecedented look at the process. The research is described in the […]

New Cassini Image of Saturn's Moon Tethys

NASA has released a new image of Saturn’s moon Tethys. The image was taken at a distance of approximately 186,000 miles (300,000 kilometers) by NASA’s Cassini Spacecraft. With the expanded range of colors visible to Cassini’s cameras, differences in materials and their textures become apparent that are subtle or unseen in natural color views. Here, […]

Hubble Image of Planetary Nebula NGC 6565

This newly released Hubble image shows planetary nebula NGC 6565. A dying star’s final moments are captured in this image from the NASA/ESA Hubble Space Telescope. The death throes of this star may only last mere moments on a cosmological timescale, but this star’s demise is still quite lengthy by our standards, lasting tens of […]

Curiosity Rover Discovers Unusual Bedrock on Mars

After almost three years on Mars, NASA’s Curiosity Mars Rover continues to amaze. This time Curiosity has discovered a target unlike anything it has studied before – bedrock with surprisingly high levels of silica. Silica is a rock-forming compound containing silicon and oxygen, commonly found on Earth as quartz. This area lies just downhill from […]
