Hubble Space Telescope imagery of galaxy ESO 381-12 (a.k.a. PGC 4287) may show the after effects of a galactic merger. Telltale 'shells' of gas and dust could be results of "shock waves through its structure much like ripples in a pond."

Neptune's rotational axis (28.3°) is a little more tilted than Earth's (23.5°) and, because it has no solid surface, its equatorial atmosphere spins more slowly (18 hrs.) than its magnetic field (16 hrs.).

Nearly 30 observations were lost due to a glitch during a system update on July 4th, 2015. NASA principal investigator Alan Stern lists the data that will not be retrieved from July 4th until July 7th.
06 July 2015, 10:21 AM ET
Black and white imagery from the NASA probe's LORRI instrument is combined with color data from the Ralph instrument to create the first color time-lapse of the Pluto-Charon orbital "dance". Also, the New Horizons team released an artist impression

The constellation Scorpius has a 'reddish star at at its 'heart' and guards a treasure-trove of nigh sky targets. Venus and Jupiter hang low in the western sky and the annual Delta Aquarid meteor shower peaks at the end of the month.
02 July 2015, 04:12 PM ET
The constellation Sagittarius looks like a teapot and will be spew Milky Way 'steam' (aka center of our galaxy) this month. The area is frothy with nebulae, star clusters and, if you have a really good telescope, Pluto.
02 July 2015, 02:24 PM ET
In 2018, a fast moving pulsar (J2032+4127) will whip through its companion star's disk of gas and dust creating an incredible display for gamma ray detectors to reveal. The star (MT91 213) is 15 times larger than the Sun.
02 July 2015, 10:54 AM ET
The latest New Horizons' data pouring into NASA servers on Earth has returned color and black & white images of Pluto and Charon and more. The strange dark spots, seen in the approximate true color view, are oddly very similar.
