Travelers In The Night

A real "Science Snack" for anyone who is interested in the extraterrestrial. Dr. Al Grauer is a member of the Catalina Sky Survey which has led the world in near Earth asteroid discoveries for 17 of the past 19 years. The music is "Eternity" by John Lyell.

    838-Webb-Asteroid-Discoveries

    Using high powered graphics processing units, a team of 21 astronomers led by Dr. Artem Y. Burdanov of MIT used 93 hours of data from the James Webb Space Telescope or JWST for short to serendipitously search for asteroids which happened to be present in images taken in the of study planets circling distant stars. JWST and the new Vera C. Rubin Observatory will help to fill in asteroid hunters current blind spots. Better asteroid impact prediction will allow asteroid hunters to warn people to stay away from doors and windows and take shelter in the event of an Earth bound space rock much as weather forecasters do currently with tornados and hurricanes.

    325E-344-Gnats

    Near Earth Asteroids or NEAs which are accessible are those objects whose orbits bring them close to Earth at speeds which are reachable by our rockets. They are potential space mission targets for science as well as for asteroid mining to obtain the raw materials necessary for humans to colonize space.

    837-Weird Extraterrestrial Life

    We will continue to search for life as we know it by studying the chemistry of the atmospheres of extraterrestrial planets and trying to detect signals from alien civilizations while being aware that alien life could be so weird that it is unrecognizable

    836-Jacqui's Comet

    My Catalina Sky Survey teammate Jacqueline Fazekas was asteroid hunting with our 60 inch telescope on Mt. Lemmon, Arizona when she spotted a glowing patch of light moving through the constellation of Cancer.By discovering her first comet Jacqui became the 483 person to discover a comet since 1758 when Charles Messier created a catalogue of diffuse objects to help fellow comet enthusiasts not be fooled by gas clouds and galaxies in their search for a new comet.

    323E-342-That's Close

    My Catalina Sky Survey teammate Greg Leonard discovered an asteroid, 2017 EA, which is so tiny that it could pass under a basketball hoop. It missed exploding in our atmosphere by only about 9,000 miles as it streaked between the communications satellites and the surface of our planet high above the eastern pacific ocean. After Greg discovered it, this small celestial visitor was tracked by telescopes in Arizona, New Zealand, and New Mexico before it disappeared into the Earth's shadow. When this tiny space rock emerged from our planet's shadow it was too close to the Sun for further observations by ground based telescopes. However, our observations pinned down it's orbit around the Sun well enough, for astronomers to conclude that it will not come this close to us again during the next six encounters with Earth from 2019 to 2126.

    835-Bok Impactor

    My Catalina Sky Survey teammate Vivian Carvajal was asteroid hunting in the constellation of Aries with the Steward Observatory 90 inch Bok telescope on Kitt Peak, Arizona when she spotted a fast moving point of light in a set of her images. Nearly 10 hours later it entered the Earth’s atmosphere over Eastern Siberia north of Olekminsk

    322E-341-Ballooning to Space

    To travel to the edge of space you can strap yourself into a capsule and ride atop of a carefully controlled explosion or you can enter a crew capsule and be gently lifted by a balloon into the stratosphere. Unlike a suborbital rocket flight lasting for a few minutes a ride under a balloon can give you several hours to enjoy the wonders of the Earth and its curvature against the back drop of space. Tucson based World View Enterprises is on track to take you on such a balloon ride to the edge of space for the price of a $75,000 ticket. This innovative company is getting started with an unmanned balloon borne capsule called the Stratollite.

    834-Dark Comets

    From our vantage point on planet Earth asteroids appear as moving points of light which strictly follow the law of gravity as they orbit the Sun. On the other hand comets appear as gas clouds which sometimes deviate from their gravitational orbits when they burp bursts of gases as they are warmed by the Sun. Dark comets appear as points of light like asteroids but move through space as though they are influenced by small rocket like bursts of volatile materials in cometary fashion.
