Plotting a parabola around the sun with #comet #96PMachholz
Comet Machholz Approaches the Sun
Why is Comet Maccholz so depleted of carbon-containing chemicals? Comet 96P/Machholz's original fame derives from its getting closer to the Sun than any other short period comet -- half as close as Mercury -- and doing so every five years.

To better understand this unusual comet, NASA's Sun-monitoring SOHO spacecraft tracked the comet during its latest approach to the Sun in October. The featured image composite shows the tail-enhanced comet swooping past the Sun. The Sun's bright surface is hidden from view behind a dark occulter, although parts of the Sun's extended corona are visible.

Neighboring stars dot the background. One hypothesis holds that these close solar approaches somehow cause Comet Machholz to shed its carbon, while another hypothesis posits that the comet formed with this composition far away -- possibly even in another star system.

The reentry of old Chinese space station #Tiangong1 is expected for the 02 mach 2018 23:00 UCT above France or Spain . Since the satellite is out-of-control the precise date will probably change , what a pity, I would be in the best place to see the huge fireball of the 8 tonnes satellite burning in Earth atmosphere :-) More informations :

Chinese Space Station, Tiangong 1 glides through Orion over Williamsburg, Virginia. Early next year it's orbit will decay enough that the 8.5 ton spacecraft will come crashing back to earth. Photo by Chris Becke

Nice composite image of a #Falcon9 rocket launch !
I stacked ten photos that I took during a Falcon 9 rocket launch to create an interesting progression image.
