Comet 46P/Wirtanen will be making a close pass of Earth December 16, 2018. It will be at its closest distance to Earth in over four centuries. It is a member of the Jupiter family of comets - their farthest point from the sun being near the orbit of Jupiter. It will be bright enough to see with the naked eye above the eastern horizon all month long, and can be seen even better with a telescope and/or binoculars. This 120 second image of the comet was taken Dec. 2 by an iTelescope 50 mm refractor located at an observatory near Mayhill, New Mexico. The streak below the comet was produced by a rocket body (upper stage) passing through the telescope's field of view during the exposure. Specifically, the upper stage is the one that placed the Indonesian Garuda 1 communications satellite into geostationary orbit back in February of 2000. At the time of this image, the Garuda 1 upper stage was 15,880 miles from the observatory; Comet Wirtanen was 10.3 million miles distant. Image Credit: NASA

A south tropical disturbance has just passed Jupiter's iconic Great Red Spot and is captured stealing threads of orange haze from the Great Red Spot in this series of color-enhanced images from NASA's Juno spacecraft. From left to right, this sequence of images was taken between 2:57 a.m. and 3:36 a.m. PDT (5:57 a.m. and 6:36 a.m. EDT) on April 1, 2018, as the spacecraft performed its 12th close flyby of Jupiter. Citizen scientists Gerald Eichstädt and Seán Doran created this image using data from the spacecraft's JunoCam imager. Credits: NASA/JPL-Caltech/SwRI/MSSS/Gerald Eichstädt/Seán Doran

This image from Parker Solar Probe's WISPR (Wide-field Imager for Solar Probe) instrument shows a coronal streamer, seen over the east limb of the Sun on Nov. 8, 2018, at 1:12 a.m. EST. Coronal streamers are structures of solar material within the Sun's atmosphere, the corona, that usually overlie regions of increased solar activity. The fine structure of the streamer is very clear, with at least two rays visible. Parker Solar Probe was about 16.9 million miles from the Sun's surface when this image was taken. The bright object near the center of the image is Jupiter, and the dark spots are a result of background correction. Credits: NASA/Naval Research Laboratory/Parker Solar Probe
