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 […]
See photos and images of the Mars-bound comet C/2013 A1 Siding Spring, which will buzz the Red Planet on Oct. 19, 2014. Comet Siding Spring was discovered in January 2013. Its pass through the inner solar system will be closely watched by Mars probes.
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 [... […]
Here's a robot video that I found interesting: Bre Pettis: “Totally psyched about the Solidscape MAX2 High Precision 3D Printer. Wax models are the gateway to metal models.” This is the most hotly anticipated 3D printer at Bold Machines. We've been drooling over it on the Solidscape website and now we came to get our [...]
