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
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
A newly discovered near-Earth asteroid "2014 HQ124" now dubbed "The Beast" will make its closest approach to the Earth on June 8, 2014. Just before 06:00 UTC "The Beast" will flyby our planet at a close but safe distance of 0.0084 AU (3.3 L
A hyperbolic comet C/2012 K1 PanSTARRS will make its closest approach to the Sun on August 27, 2014. On that day, it will approach the Sun at the distance of 1.05 AU (157 million km, 98 million miles) and buzz Earth'
NASA released a new image of a comet C/2013 A1 – Siding Spring today. With relative speed of 56 km/s this comet will pass extraordinarily close to Mars on October 19, 2014. It is expected to fly by Mars within 135 185 km (84 000 miles), which
Newly discovered Apollo class asteroid named 2014 DX110 will safely fly by Earth on Wednesday, March 5, 2014 at around 21:07 UTC. The estimated size of this asteroid is 30 meters (98 feet) and it will fly by at a minimum distance of less than 350 000 km (217
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.
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
In November 2013, skywatchers around the world eagerly awaited the approach of Comet ISON. Dubbed the "Comet of the Century" by several in the media, some astronomers had predicted a stupendous cometary display as Comet ISON approached its perihelion.
The
The past few weeks have been an unusually active time for comet watchers as four comets were visible simultaneously with binoculars: ISON, Lovejoy, Encke, and LINEAR.
Although less known than ISON, newly discovered
