Venus continues to dominate the morning sky in the east, but appears slightly lower in the sky each morning as it pulls ahead of us in its orbit.
The waning crescent Moon will appear near Venus the the star Aldebaran on the mornings of July 19th and 20th. The New Moon will be on the 23rd.
Jupiter and Saturn appear in the south-southwestern sky after sunset; Jupiter will appear slightly lower in the western sky each day as the Earth pulls ahead of Jupiter in its orbit.
The constellations Pegasus and Andromeda appear low in the northeast sky after sunset; the wispy cloud of M31, the Andromeda galaxy, makes a good target for telescope observers.
M31 is the nearest major galaxy to the Milky Way. It is 2.5 million light years distant, and heading straight at us; in a little over 4 billion years, it will collide with the Milky way, and the two galaxies will merge into a large elliptical galaxy.
Don't expect M31 to look like this time-exposure image in your backyard telescope tho - it typically appears as a circular blue-greenish cloud, surrounded by a larger and dimmer cigar-shaped cloud.
In January of 2015, the Hubble Space Telescope team released this GIANT mosaic image of the Andromeda galaxy. There is a clickable-version that lets you explore a 48,000-light-year-long swath of the Andromeda galaxy in exquisite detail.
