Where on Earth…? MISR Mystery Image Quiz #17
Here’s another chance to play geographical detective! This natural-color image from the Multi-angle Imaging SpectroRadiometer (MISR) represents an area of about 372 kilometers x 425 kilometers, and was captured by the instrument’s vertical-viewing (nadir) camera in December 2000. Only some…
An Abrasive Collision Gives One Galaxy a “Black Eye”
A collision of two galaxies has left a merged star system with an unusual appearance as well as bizarre internal motions. Messier 64 (M64) has a spectacular dark band of absorbing dust in front of the galaxy’s bright nucleus, giving…
Iceland
True to its name, Iceland is shown here covered in a white blanket of ice and snow. Low layers of clouds float over the Greenland Sea (left) and the Atlantic Ocean (bottom). Iceland’s southern, low-lying coastlines are greyish-tan, while the…
New Hubble Study Reveals How Black Holes Get Their Kicks
When black holes collide, look out! The “kick” from an enormous burst of gravitational radiation that occurs during the collision could knock a black hole clear out of its galaxy, rather than resulting in one massive black hole, as commonly…
Registan Dunes
In southern Afghanistan, shifting sand dunes flow across the huge, sandy desert known as the Registan. When the winds constantly blow from the same direction over relatively flat terrain with a small to moderate amount of sand, the sand will…
Supernova Blast Bonanza in Nearby Galaxy
The nearby dwarf galaxy NGC 1569 is a hotbed of vigorous star birth activity which blows huge bubbles that riddle the main body of the galaxy. The galaxy’s “star factories” are also manufacturing brilliant blue star clusters. This galaxy had…
LIDAR: In the Wake of the Storm
To understand how severe storms like Hurricane Isabel shape coastal areas, NASA and USGS scientists mapped the North Carolina coastline before and after Isabel came ashore.
Glacial Retreat in Argentina
For the crew onboard the International Space Station daylight views of the Earth’s Southern Hemisphere offer fewer opportunities to observe and document land features with onboard cameras. However, South America’s Patagonian Ice Fields and glaciers in the far southern Andes…
Oxygen and Carbon Found in Atmosphere of an Extrasolar Planet
NASA’s Hubble Space Telescope has detected, for the first time ever, the presence of oxygen and carbon in the atmosphere of a planet outside our solar system. The oxygen naturally exists and is not produced by any sort of life…
Brandberg Massif, Namibia
Over 120 million years ago, a single mass of granite punched through the Earth’s crust and intruded into the heart of the Namib Desert in what is now northern Namibia. Today the mountain of rock called the Brandberg Massif towers…
A Deadly Year for Earthquakes
Last year, more people died in earthquakes than in any other year since 1990, according to a recent statement released by the United States Geological Survey (USGS, click to read the press release). As of January 7, 2004, the United…
Pacific Dictates Droughts and Drenchings
New research presented at the 2004 meeting of the American Meteorological Society suggests that the cooler, drier conditions in Southern California over the last few years may be the result of a long-term pattern in the ocean known as the…
Significant Event Report for Week Ending 1/30/2004
Cassini Significant Event Report For Week Ending 01/30/04 The most recent spacecraft telemetry was acquired from the Goldstone tracking station on Monday, January 26. The Cassini spacecraft is in an excellent state of health and is operating normally. Information on…
South Sandwich Island Cloud Wakes
In the Southern Atlantic, a chain of eleven volcanic islands rises up from the ocean in an arc that extends roughly 240 miles (400 km) north to south. As is apparent in this true-color image, the islands are tall enough…
Topography of Bali
The volcanic nature of the island of Bali is evident in this shaded relief image generated with data from the Shuttle Radar Topography Mission (SRTM). Bali, along with several smaller islands, make up one of the 27 Provinces of Indonesia.…
