Mars spacecraft preparing for Comet Siding Spring's close flyby

As Comet C/2013 A1 Siding Spring heads toward a close flyby of Mars on October 19, 2014, NASA and ESA are both taking steps to protect their Mars orbiters, while still preserving opportunities to gather valuable scientific data. Six days after p

Comet ISON's dramatic final hours - new analysis

A new analysis of data from the ESA/NASA Solar and Heliospheric Observatory (SOHO) spacecraft has revealed that comet 2012/S1 (ISON) stopped producing dust and gas shortly before it raced past the Sun and disintegrated.When comet ISON was discovered in the autumn of 201

Swift calculates water production of Mars-bound comet Siding Spring

In late May, NASA's Swift satellite imaged comet Siding Spring, which will brush astonishingly close to Mars on October 19, 2014. These optical and ultraviolet observations are the first to reveal how rapidly the comet is producing water and allow astronomers to

Asteroid diversity points to a "snow globe" solar system

Our solar system seems like a neat and orderly place, with small, rocky worlds near the Sun and big, gaseous worlds farther out, all eight planets following orbital paths unchanged since they formed. However, the true history of the solar system is more riotous.

Comet Siding Spring set for a close encounter with Mars - epic meteor shower expected

C/2013 A1 (Siding Spring) is a long-period comet set for a very close encounter with Mars later this year. Although early estimates of its orbit showed a good possibility of impact, latest observations suggest a near miss and raise great concern for Mars
