590-Noctilucent Clouds

See Climate Change! Noctilucent Clouds exist at more than 50 miles above the Earth's surface or about 4 times higher than the tops of the most intense tropical thunder storms. Climate change has caused these once very rare clouds to become a common occurrence.

78E-90-Shine Little Asteroid Shine

Recently I was observing with the NASA funded Catalina Sky Survey 60 inch on Mt. Lemmon, Arizona when I discovered a 200 foot diameter asteroid, 2014 SC324. It is in an orbit around the Sun which takes it from inside our planet's path to 60% of the way to Jupiter. This is an unusual Earth approaching space rock in that it gets bright enough to be imaged with a small telescope equipped with an electronic camera.

589-Defending Earth

The International Asteroid Warning Network, or IWAN (Eye-Whan) for short has been established to link scientists who are discovering, monitoring, and physically characterizing potentially dangerous asteroids. In the future the coordinated efforts of IWAN members will indicate where to search for meteorites giving you a chance to hold a 3 to 5 billion year old traveler in the night.

77E-89-Witnessing An Asteroid Impact

Recently I discovered a small asteroid with the NASA funded Catalina Sky Survey 60 inch telescope on Mt. Lemmon. This space rock is about 200 feet in diameter and will never get closer than 1/4 of the distance to the Moon. A friend asked what it would be like to witness the impact of such an object.

588-Encounter With Saturn

From 1663 to 2011, seven comets had close encounters with Jupiter and two had close encounters with Saturn. In May of 1936, Comet P/2020 F1 Leonard had a close encounter with Saturn. In the distant past, Comet Leonard was captured by Jupiter and is now part of the giant planet's family of comets.

76E-88-Space Rocks

Asteroid 2008 TC3 is the only asteroid which was observed to be hurtling between planets, flying through our atmosphere, and pieces of it found to be lying on the Earth's Surface. NASA funded, Catalina Sky Survey team member, Richard Kowalski discovered it 20 hours before it hit. Airline pilots spotted it flying through the sky. Eventually, searchers were rewarded with pieces of it on the sands of the Sudanese desert.

587-Quiet Sun

Images of the quiet Sun during a solar minimum make it look like a relatively static peaceful place. Occasionally during solar minimum, at the Cosmic Campground, in New Mexico, on a clear moonless night, you can easily see to walk around without a flashlight and with a DSLR camera photograph the sky which to the camera appears to be covered with orange and green cirrus clouds through which you can see the Milky Way.

75E-87-MOM Reaches Mars

India's Mars Orbiter Mission or MOM has made the 10 month journey from Earth to Mars. India joins the United States, Russia, and the European Space Agency in the exploration of the red planet by placing its Mangalyann [Mangle Yarn] spacecraft into orbit around Mars.

586-Northern PHA

My Catalina Sky Survey teammate David Rankin was observing in the constellation of Ursae Major with our 60 inch telescope on Mt. Lemmon, Arizona when he spotted a rare fast moving point of light far north of the area in the sky which contains the planets and most of the asteroids.

74E-86-A Close Flyby

Recently a semi-trailer trailer truck sized asteroid passed only 20,800 miles above the Earth's surface. It reached its closest distance to us about 6 days after it was discovered by team member, Richard Kowalski, of the NASA funded Catalina Sky Survey. Fortunately it did not enter our atmosphere.
