What causes meteor showers? ---- How to observe meteor showers. Copyright 2008 David K. Lynch. All Rights Reserved. "Shooting stars", "falling stars" or meteors, call them what you like. These pinpoints of light that streak across the night sky are tiny bits of rock from space. They enter our atmosphere at speeds up to 71 km/s (~158,000 mph).
Himalaya Satellite Image Map This is a Landsat GeoCover 2000 satellite image map of the Himalaya mountain range - the longest and tallest mountain range on Earth. The Himalayas form a 1500-mile arc through northeastern Pakistan, northern India, southern Tibet, Nepal, Sikkim, and Bhutan. To the north is the high plateau of central Asia and to the south are the plains of central India.
Explosive phytoplankton growth spreads blooms across hundreds of miles of ocean. Article by: Hobart M. King, Ph.D., RPG This image is a satellite view of a phytoplankton bloom that developed in the Atlantic Ocean off the coast of Namibia in 2008. The bloom first appeared about October 28 and began to dissipate by November 14.
There are hundreds of man-made islands in the Persian Gulf. A satellite image of Dubai's artificial islands in February 2009. From left to right: Palm Jebel Ali, Palm Jumeirah, and The World. NASA image created by Jesse Allen. Click to enlarge. Palm Jumeirah is the world's largest artificial island. Vegetation appears red in this false-color satellite image from 2010.

Google Earth is a free program from Google that allows you to "fly" over a virtual globe and view the Earth through high-resolution graphics and satellite images.
AN INTRODUCTORY GUIDE TO METEORITE IDENTIFICATION The third in a series of articles by Geoffrey Notkin, Aerolite Meteorites Meteorwrong: Slag-sometimes called cinder or runoff-is a by-product of metal smelting and usually consists of a conglomerate of metal oxides. Slag is one of the substances most commonly mistaken for meteorites, as it appears burned and melted on the surface and often sticks to a magnet due to its high iron content.
THE HEARTS OF LONG-VANISHED ASTEROIDS The sixth in a series of articles by Geoffrey Notkin, Aerolite Meteorites Gibeon slice: A large polished end cut of the Gibeon (IVA), fine octahedrite iron, first discovered in 1836 in the Namib Desert, Namibia. Gibeon is prized by collectors for its beautiful etch pattern, and popular with jewelers as it is a very stable iron and not prone to rusting.
This moon of Jupiter might have life in a subsurface ocean. Life on Europa: Water from a subsurface ocean on Jupiter's moon, Europa, could reach the surface through seeps or erupt from hot water vents. This water would reveal the chemistry of the subsurface ocean and may contain microbes that live below.
Meteorites from Antarctica: Incredible numbers of nearly perfect meteorites are being found in the "blue ice" ablation areas of Antarctica. The photo above shows several specimens collected from the Miller Range icefield by NASA's Antarctic Search for Meteorites. Image by NASA. Meteorite find: When meteorite hunters find a specimen in the field, it is photographed on-site with a measurement scale and an identification number visible in the background.
The second in a series of articles by Geoffrey Notkin, Aerolite Meteorites Iron Meteorite: Detail of a polished and etched slice from a siderite (iron) meteorite found in the Brenham, Kansas strewnfield in 2005 by professional meteorite hunter Steve Arnold. The slice has been etched with a mild solution of nitric acid to reveal an interlocking pattern of iron-nickel alloys, taenite and kamacite.
A GUIDE TO COLLECTING AND THE METEORITE MARKETPLACE The fourth in a series of articles by Geoffrey Notkin, Aerolite Meteorites Nininger Iron Meteorites: Three small iron meteorites which carry hand painted H.H. Nininger American Meteorite Laboratory collection numbers. We know from old AML publications that "D91" was Nininger's prefix for the Odessa, Texas iron meteorite.
The tenth in a series of articles by Geoffrey Notkin, Aerolite Meteorites Arizona stone meteorites: A collection of Arizona stone meteorites displayed in a glass cabinet to protect them from dust and accidental damage. The larger stones, above left, are an assortment of complete individuals, slices, and end cuts from the Gold Basin strewnfield (L4, Mohave County, Arizona).

Used with permission. Meteors and "Shooting Stars" Meteors are most often seen as a very brief streak of light in the night sky.
THE BEST OF BOTH WORLDS The ninth in a series of articles by Geoffrey Notkin, Aerolite Meteorites Huge pallasite at Brenham strewnfield: The author (above left) and his hunting partner, Steve Arnold, with a 230-lb pallasite from the famous Brenham, Kansas strewnfield. The mass was discovered by us while filming the Science Channel documentary "Meteorite Men" in the fall of 2008.

A volcano is the tallest mountain - An asteroid crater is the deepest basin Article by: Hobart M. King, Ph.D., RPG Spectacular events determined the highest and lowest elevation points on Mars. The lowest point was blasted by an enormous asteroid impact which formed the Hellas Impact Crater. The highest point was built by repeated eruptions of Olympus Mons, the largest volcano in our solar system.
One of the most famous images of the “Southern Lights” Article by: Hobart M. King, Ph.D., RPG Aurora Australis: Composite satellite image of the Aurora Australis (southern lights) from space. The image was compiled by superimposing data of the Aurora Australis collected by NASA IMAGE satellite atop of an image of Earth from a south polar perspective from the Blue Marble project.
What are they and where do they come from? By David K. Lynch, Copyright 2007 All Rights Reserved. Artist's conception of an asteroid impact. NASA image. Ever since the Earth formed 4.5 billion years ago, it has been bombarded with rocks from space. Each year about 50,000 tons of asteroidal material enters the Earth's atmosphere.
"Pluto is showing us a diversity of landforms and complexity of processes that rival anything we've seen in the solar system." - Alan Stern, New Horizons Principal Investigator. Snakeskin topography on Pluto: Scientists at NASA don't know how to interpret the geology of a recent image of Pluto that shows a 300-mile-wide scan of landscape.
The first in a series of articles by Geoffrey Notkin, Aerolite Meteorites Sikhote-Alin Iron Meteorite: A fine example of a Sikhote-Alin iron meteorite, weighing 409.9 grams, which was seen to fall in eastern Russia in February of 1947. This meteorite is described as an individual, as it is a complete mass (rather than an exploded shrapnel fragment) which fell to earth on its own.
