Why are we seeing so many sungrazing comets?
Ver en NASA ↗Oliver Price, a planetary science PhD student at University College London’s Mullard Space Science Laboratory in the United Kingdom, has developed a new image-processing technique to mine through the wealth of data about comet tails.
Ver en NASA ↗On October 19, 2014, Comet Siding Spring will make a remarkably close encounter with Mars, buzzing the Red Planet at just one third of the Earth-Moon distance. To witness this historic event, NASA has mobilized an entire fleet of rovers, orbiters, Earth obser…
Ver en NASA ↗A comet's journey through the solar syste is perilous and violent. Before it reaches Mars - at some 230 million miles away from the sun - the radiation of the sun begins to cook off the frozen water ice directly into gas.
