Travelers In The Night Albert D. Grauer

More than 400 years ago Galileo Galilei expanded human vision using a telescope to view the cosmos. Since then humans have extended their senses to view the Universe in x-rays, ultraviolet, infrared, radio, and other portions of the electromagnetic spectrum not accessible to our senses. In a pioneering effort, Ekaterina Smirnova has employed the spectroscopy, magnetometry, and molecular data collected by the Rosetta spacecraft to create watercolor paintings, sculptures, a musical collaboration, and an augmented reality project to create new art forms. She has also taken Rosetta data obtained from it's close up observations of comet 67P to create interactive art which uses a smart phone app to experience scientific results in a completely new way.

The Cosmic Campground International Dark Sky Sanctuary and the Aldo Leopold Gila Wilderness in New Mexico are gateways to nature where man is only a visitor.These New Mexico neighbors give us a sense of wonder, glimpses of history, new knowledge to mitigate the effects of man’s excesses, and many other opportunities we are yet to fully appreciate.

A pair of comets visiting our neighborhood are discovered in a matter of 4 days.
One of the perks of being an asteroid hunter is having a comet named for you. To do this you must be the first to discover it as a moving point of light in the night sky and at the same time recognize that it is a comet by observing the coma and tail which are names for the clouds of gas and dust that surrounds it. After being on the lookout for a comet for sometime, my Catalina Sky Survey teammate Rose Matheny discovered two of them within a 4 day period of time. Both of them C/2016 T1 (Matheny) and C/2016 T2 (Matheny) are likely to be first time visitors to the inner solar system. These two comets have quite different paths which are both inclined at large angles to the paths of the planets about the Sun. In addition, both of them are traveling at very close to the escape velocity from our solar system and have uncertain orbital periods around the Sun which are likely to be thousands of times the age of the Universe.

Life on Earth appears to have formed in our oceans. Scientists are thus on the hunt for other worlds which have oceans of liquid water and thus potentially could be the home of fellow living creatures.

Using a small telescope or a set of binoculars you can see Europa for yourself as a small moving point of light circling the giant planet Jupiter. More than 400 years after Galileo Galilei discovered this seemingly small dead world the Hubble Space Telescope spotted geysers erupting from its south polar regions. Recently, over a 15 month period, the Hubble was able to observe 10 transits of Europa across the face of Jupiter. On three such occasions plumes were seen to be erupting from this small moon.

It is essential that asteroid hunters keep track of potentially dangerous asteroids to make sure that their orbits haven’t changed as they encounter other objects in space to make them a threat to our home planet.
