On July 13th, a good place to watch Comet Jacques was from Venus. Then, the recently discovered visitor (C/2014 E2) to the inner solar system passed within about 14.5 million kilometers of our sister planet. Still, the outbound comet will pass only 84 million kilometers from our fair planet on August 28 and is already a fine target for telescopes and binoculars.
Two days ago, Jacques' greenish coma and straight and narrow ion tail were captured in this telescopic snapshot, a single 2 minute [...]
A team of astronomers from the National Astronomical Observatory of Japan (NAOJ), the Konan University and the University of Hyogo in Japan, the University of Notre Dame, and New Mexico State University (Note 1) has used the 8.2 m Subaru Telescope's High Dispersion Spectrograph (HDS) to discover a low-mass star, SDSS J0018-0939 (Fig. 1), that exhibits the peculiar chemical abundance ratios associated with the process of creating new atomic nuclei (nucleosynthesis) in a first-generation very-mass [...]

Expedition 40 Commander Steve Swanson of NASA and his team of five flight engineers focused on computer upgrades, science and cargo operations Thursday aboard the International Space Station, while the deployment of a flock of miniature satellites got under way again.
Following the crew’s usual 2 a.m. EDT reveille and a daily planning conference with the flight control teams around the world, Russian cosmonauts Alexander Skvortsov and Oleg Artemyev wrapped up the stowage of the tools they [...]
The moon appears to be a tranquil place, but modeling done by University of New Hampshire (UNH) and NASA scientists suggests that, over the eons, periodic storms of solar energetic particles may have significantly altered the properties of the soil in the moon's coldest craters through the process of sparking—a finding that could change our understanding of the evolution of planetary surfaces in the solar system.
The study, published August 8 in the Journal of Geophysical Research-Planets, [...]
The heat shield on NASA’s Orion spacecraft gets all the glory when it comes to protecting the spacecraft from the intense temperature of reentry. Although the blunt, ablative shield will see the highest temperatures – up to 4,000 degrees Fahrenheit on its first flight this December – the rest of the spacecraft is hardly left in the cold.
Engineers and technicians at NASA’s Kennedy Space Center have finished installing the cone-shaped back shell of Orion’s crew module – the protect [...]
