You must be ready to accept the possibility that there is a limitless range of awareness for which we now have no words; that awareness can expand beyond range of your ego, your self, your familiar identity, beyond everything you have learned, beyond your notions of space and time, beyond the differences which usually separate people from each other and from the world around them.
This image of the NGC 1398 galaxy was taken with the Dark Energy Camera.
This galaxy lives in the Fornax cluster, roughly 65 million light years from Earth. It is 135,000 light years in diameter, just slightly larger than our own Milky Way galaxy, and contains more than a hundred million stars. Credit:Dark Energy Survey
Uranus is the only giant planet whose equator is nearly at right angles to its orbit. A collision with an Earth-sized object may explain Uranus’ unique tilt. Nearly a twin in size to Neptune, Uranus has more methane in its mainly hydrogen and helium atmosphere than Jupiter or Saturn. Methane gives Uranus its blue tint.
Featured Mission: Voyager 2 Most of what we know about Uranus came from Voyager 2’s flyby in 1986. The spacecraft discovered 10 additional moons and several rings before heading on to Neptune.
One of HST’s most cited set of observations was the series of images taken in July 1994 as the dishevelled remnants of Comet Shoemaker-Levy 9 crashed into Jupiter. That event highlighted the catastrophic consequences of cosmic impacts, and sparked considerable interest in identifying earth-crossing asteroids and comets. Fifteen years later, on 19 July 2009, an Australian amateur astronomer, Anthony Wesley, noticed a strange dark ‘scar” near Jupiter’s southern pole. The feature was quickly confirmed by other astronomers, both amateur and professional, and was quickly judged as likely to be the result of another, completely unexpected, cometary impact. The SL9 impact was thought to be a once-in-a-lifetime (if not more) event; clearly, the impact rate is higher than previously suspected. At the time of the new event, HST was deeply immersed in the initial on-orbit instrument performance tests, but the science staff were able to interrupt those procedures for a few orbits to obtain images with Wide-Field Camera 3. Further observations will be obtained at a later date to track the evolution of the feature, as Jovian winds disperse the detritus through the atmosphere.
