The Chinese Chang’e 5 test vehicle captured this extraordinary view of Earth over the far side of the moon yesterday. From Earth, the phase of the moon was a waxing crescent. From the moon, the Earth is in a waning gibbous phase. More detail about features visible on this photo on the far side of the moon, inside.
This NASA Hubble Space Telescope composite image captures the positions of Comet Siding Spring and Mars in a never-before-seen close passage of a comet by the Red Planet. The close encounter took place at 2:28 p.m. EDT October 19, 2014. The comet passed by Mars at approximately 87,000 miles, or about one-third of the distance between Earth and the moon! At that time, the comet and Mars were approximately 149 million miles from Earth.

Favorite photos of the beautiful partial solar eclipse on October 23. Thank you to all who submitted to EarthSky.org or posted at EarthSky Facebook or G+.
Two cool nighttime photos by astronauts aboard the ISS. Check out the bright city lights.
Hurtling through space at about 35 miles (56 kilometers) per second, Comet Siding Spring (C/2013 A1) swept closest to Mars on October 19, 2014. It swept extremely close to the planet, closer than any known comet in recorded history. We’re just beginning to see the photos from this event. See the best ones here …

It was very windy out, so some of the trees appear blurry. The full moon was also behind me, so I was able to use that as a natural light source for the foreground.
Rolando Ligustri in Italy caught Comet C/2013 A1 Siding Spring passing nearly in front of M6 – sometimes called the Butterfly Cluster – in the tail of the constellation Scorpius on October 9. Professional astronomers recently announced the comet began losing brightness in September. But it is still beautiful, and still has a sweeping comet tail. Its close encounter with the planet Mars on October 19 – one week from today – is much anticipated.
This unnamed crater is only 1.5 kilometers / 0.93 miles wide. It’s made more visible by the deep shadows cast on a Mercury afternoon.
A beautiful total lunar eclipse. Thanks to all who posted at EarthSky Facebook and G+!
