    Motion interpolation of seven images of the HR 8799 system taken from the W. M. Keck Observatory over seven years, featuring four exoplanets. This is a list of extrasolar planets that have been directly observed, sorted by observed separations. This method works best for young planets that emit infrared light and are far from the glare of the star.

    The 24-inch (610 mm) Dobsonian telescope brought by the Sidewalk Astronomers was unconventional, because most telescopes at such meetings tended to be smaller, on equatorial mounts, and designed for astrophotography rather than optical viewing. Surprisingly (and controversially at the time) Dobson's telescope tied in first prize for best optics.

    Raw images from Cassini were received on Earth shortly after the event, and a couple of processed images—a high-resolution image of the Earth and the Moon, and a small portion of the final wide-angle mosaic showing the Earth—were released to the public a few days following the July 19 imaging sequence.

    Telescopic observations resulted in the discovery of moons and rings around planets, and new planets, comets and the asteroids; the recognition of planets as other worlds, of Earth as another planet, and stars as other suns; the identification of the Solar System as an entity in itself, and the determination of the distances to some nearby stars.
