The Sun's coronal tail wags its photospheric dog

Solar physicists have long viewed the rotation of sunspots as a primary generator of solar flares - the sudden, powerful blasts of electromagnetic radiation and charged particles that burst into space during explosions on ...

Imaging uses 'photothermal effect' to peer into living cells

A new type of imaging technology uses the mid-infrared part of the spectrum and "thermal lensing" to visualize living cells and organisms, an innovation that could bring insights into drug delivery and cancer treatment.

Compound boosts contrast of photoacoustic images

An agent for enhancing the contrast of photoacoustic imaging—an emerging imaging modality that involves 'listening' to the sound generated by laser light—has been developed by A*STAR researchers.

Juno spacecraft sends first in-orbit view

The JunoCam camera aboard NASA's Juno mission is operational and sending down data after the spacecraft's July 4 arrival at Jupiter. Juno's visible-light camera was turned on six days after Juno fired its main engine and ...
