The solar chromosphere and transition region (TR) form an interface between the Sun’s surface and its hot outer atmosphere. There, most of the nonthermal energy that powers the solar atmosphere is transformed into heat, although the detailed mechanism remains elusive. High-resolution (0.33–arc second) observations with NASA’s Interface Region Imaging Spectro […]
The heating of the outer solar atmospheric layers, i.e., the transition region and corona, to high temperatures is a long-standing problem in solar (and stellar) physics. Solutions have been hampered by an incomplete understanding of the magnetically controlled structure of these regions. The high spatial and temporal resolution observations with the Interfa […]
There's a certain irony to the observation that Tom Hanks today may be better known for flying to the moon than Alan Bean, who actually went there. The actor and director celebrates Bean and laments his anonymity in the pages of "The New Yorker."
A highly magnetized neutron Star named SGR J1550-5418 erupted with a series of powerful x-ray and gamma-ray flares on Jan 22, 2009. NASA's Swift satellite observed the outburst over the course of 6 days.
Here's a robot video that I found interesting: I've been working on a simple animatronic Chinese Lion. This video was taken just after I'd written some simple code to test all the basic functions. As you can see, the motor control code for the larger motors still needs some work. You can follow the build [...]
Here's a robot video that I found interesting: After a slightly surprising move away from a managerial role at MakerBot, former CEO Bre Pettis has finally announced what he’s working on: Bold Machines, an “Innovation Workshop” for MakerBot parent company Stratasys. Designed to be a creative skunkworks for the 3D printing company, Bold Machines will [... […]
