Scientists at Work: Most Days in the Life of an Astronomer aren’t spent at Telescopes

May 11, 2015 10:38 am | by Nicole Estefania Cabrera Salazar, Georgia State University | Articles | Comments

On a telescope at the summit of Mauna Kea in Hawaii, it’s not easy to put in a full night of work. At 14,000 feet, you’re operating at only 60 percent of the oxygen available at sea level, which makes concentrating difficult. Top that off with a shift that begins at 6:30 pm and ends at 6:30 am, and it becomes hard to imagine astronomers working like that year-round. Luckily, most of us don’t have to.

First Image of the Moon Taken by a U.S. Spacecraft

April 23, 2015 3:22 pm | by NASA | News | Comments

Ranger 7 took this image, the first picture of the moon by a U.S. spacecraft, on July 31, 1964 at 13:09 UT, about 17 minutes before impacting the lunar surface. The large crater at center right is the 108 km diameter Alphonsus. Above it is Ptolemaeus and below it Arzachel. The terminator is at the bottom right corner. Mare Nubium is at center and left. North is at about 11:00 at the center of the frame.

Where does Lightning Flash most Frequently?

April 17, 2015 3:16 pm | by NASA | News | Comments

According to satellite observations, lightning flashes more often over land than over the oceans. And lightning seems to happen more often closer to the equator. The NASA Earth Observatory’s Global Lightening Activity Map shows the average yearly counts of lightning flashes per square kilometer from 1995 to 2013. Areas with the largest number of lightning flashes — as many as 150 per year per square kilometer — are bright pink.

Star Trek Tricorder is No Longer Science Fiction

April 2, 2015 10:44 am | by American Friends of Tel Aviv University | News | Comments

For the crew of the Starship Enterprise, Star Trek's "Tricorder" was an essential tool, a multifunctional hand-held device used to sense, compute and record data in a threatening and unpredictable universe. It simplified a number of Starfleet tasks, scientific or combat-related, by beaming sensors at objects to obtain instant results. A new invention may be able to turn smartphones into powerful hyperspectral sensors...

The technology behind the camera that revealed the intricate, imperfect beauty of snowflakes is now able to expose their potential danger. About three years ago, a new high-speed camera captured free-falling ice crystals so well it might as well be yelling "freeze!" Now, a less expensive, hardier version with the same incredible capability has been designed for use by departments of transportation to anticipate road conditions.

February 13, 2015 10:47 am | by NASA | News | Comments

Galaxies can take many shapes and be oriented any way relative to us in the sky. This can make it hard to figure out their actual morphology, as a galaxy can look very different from different viewpoints. A special case is when we are lucky enough to observe a spiral galaxy directly from its edge, providing us with a spectacular view like this one.

A snake-like robot designed to examine the inside of one of three melted reactors at the Fukushima Daiichi nuclear plant is ready to begin its expedition. Assessing the damage inside the reactors is a crucial step in the decommissioning of the plant, which was badly damaged by a 2011 earthquake and tsunami. Use of a remote-controlled robot is essential, because no humans can go close to the reactor chambers due to fatally high radiation.

New NASA/ESA Hubble Space Telescope images capture a rare occurrence, as three of Jupiter’s largest moons parade across the giant gas planet’s banded face. Hubble took a string of images of the event which show the three satellites — Europa, Callisto and Io — in action. The planet's four moons can commonly be seen transiting the face of Jupiter. However, seeing three of them transiting at the same time is rare.
