The Planetary Society has always enjoyed the connections between science and art, so when I saw Leila Qışın's sketches pop up on her Twitter feed during the recent New Horizons team meeting, I knew I had to share them with you.

Three years ago, on October 19, 2014, comet C/2013 A1 Siding Spring passed within 138,000 kilometers of Mars. At the 2017 meeting of the Division for Planetary Sciences of the American Astronomical Society, we heard a progress report on Mars orbiter imaging of the comet's nucleus.

Haumea has a ring! Two telescopes used in the discovery—one in Slovenia, and one in Italy—received funding from The Planetary Society's Shoemaker Near Earth Object (NEO) Grant program, which helps amateur astronomers find, track and characterize near-Earth asteroids.

A decade after leaving its first home in the solar system, Dawn is healthy and successful at its current residence around Ceres.

Next week's solar eclipse will reveal the Sun's corona, nearby bright planets and stars, and, if we get extremely lucky, a comet!

The team reported two weeks ago that the first attempts at observing 2014 MU69 were unsuccessful. But in their third try, on July 17, astronomers in Argentina saw the telltale sign of MU69's presence: a stellar wink.

Orbiting the only dwarf planet inside the orbit of Neptune, Dawn is healthy and continuing to carry out its assignments at Ceres, which includes keeping an eye on cosmic rays.

A team of scientists recently traveled to rural Argentina in the hopes of catching New Horizons' next target—Kuiper Belt object MU 69—crossing in front of a distant star.
