what is a comet? - Fireballs in the sky
... As the comet comes closer to the Sun the solar winds become stronger and blow away the coma to form a distinctive comet tail. A comet’s tail will always point away from the Sun because the solar wind exerts a force on the dust and gas particles. The tail itself is often split into two; a bright dust ...

Philae (spacecraft)
.png?width=300){kind=spacer}
Philae (/ˈfaɪliː/ or /ˈfiːleɪ/) is a robotic European Space Agency lander that accompanied the Rosetta spacecraft until it landed on comet 67P/Churyumov–Gerasimenko, more than ten years after departing Earth. On 12 November 2014, the probe achieved the first-ever soft landing on a comet nucleus. Its instruments obtained the first images from a comet's surface. Philae is monitored and operated from DLR's Lander Control Center in Cologne, Germany. Several of the instruments on Philae made the first direct analysis of a comet, sending back data that will be analysed to determine the composition of the surface.The lander is named after the Philae obelisk, which bears a bilingual inscription and was used along with the Rosetta Stone to decipher Egyptian hieroglyphs.On 15 November 2014, Philae entered safe mode, or hibernation, after its batteries ran down due to reduced sunlight and an off-nominal spacecraft orientation at its unplanned landing site. Mission controllers hoped that additional sunlight on the solar panels by August 2015 might be sufficient to reboot the lander. Philae communicated sporadically with Rosetta, from 13 June 2015 to 9 July.
