Comet Encke will fly by Mercury within 0.025 AU (3.74 million km) on November 18, 2013 and only a day later, Comet ISON will pass it at 0.24 AU. This is a unique cosmic coincidence and NASA's MESSENGER spacecraft, which is orbiting the planet,
Observers around the world are reporting that Comet ISON brightened sharply last night and is now at the threshold of naked-eye visibility. By some reports, ISON surged in brightness by approximately 2 magnitudes over last 24 hours and is now brighter than
Comet ISON is every day more and more closer to the Sun, and with every new day it reveals more new details. More astronomers report clearly visible double tail feature. Primary ion gas tail developed a dust tail companion so now Comet ISON is double tail
Comet ISON has almost completed its journey from the Oort Cloud to Sun's photosphere and is now inside the orbit of Earth. On November 28, 2013 Comet ISON will fly only 1 million kilometers (2.7 solar radii) above Sun's surface,
New studies released at the American Astronomical Society’s 45th Annual Division for Planetary Sciences meeting in Denver, Colorado suggests that Comet ISON could make it through its close perihelion passage near the Sun. Researchers Matthew Knight
Researchers at Northern Arizona University using the Spitzer Space Telescope discovered that what was thought to be a large asteroid called Don Quixote is in fact a comet. Don Quixote, whose journey stretches to the orbit of Jupiter wandered its lone,
After several weeks of being hidden behind the Sun, comet C/2012 S1 (ISON) finally emerged from solar conjunction mid August, and early, tentative measures of its brightness by CIOC hint that it is beginning to slowly brighten up.
CIOC writes: From
A NASA spacecraft that discovered and characterized tens of thousands of asteroids throughout the solar system before being placed in hibernation will return to service for three more years starting in September 2013. It will again be assisting in effort
A 152 meter wide asteroid named 2003 DZ15 will make a somewhat close flyby past our planet next week. This asteroid is about seven times the size of Chelyabinsk meteor and it poses no threat to Earth.
At 00:37 UTC on Tuesday, July 30, 2013, it
More than 10,000 asteroids and comets that can pass near Earth have now been discovered. The 10,000th near-Earth object, asteroid 2013 MZ5, was first detected on the night of June 18, 2013, by the Pan-STARRS-1 telescope, located on the 3,000-meter summit of the
