Hubble images globular cluster Liller 1

The muted red tones of the globular cluster Liller 1 are partially obscured in this image by a dense scattering of piercingly blue stars. In fact, it is thanks to Hubble's Wide Field Camera 3 (WFC3) that we are able to see ...

Controlling the waveform of ultrashort infrared pulses

An international team of laser physicists of the attoworld team at LMU and the Max Planck Institute of Quantum Optics has achieved unprecedented control over light pulses in the mid-infrared wavelength range.

A vertical matrix X-ray detector for multi-energy discrimination

There are three types of cone cells in the retina that are called L-cones (sensitive to red light), M-cones (sensitive to green light), and S-cones (sensitive to blue light). The coordinated response of cone cells to visible ...

Examining the heart of Webb: The final phase of commissioning

NASA's James Webb Space Telescope is now experiencing all seasons—from hot to cold—as it undergoes the thermal stability test. Meanwhile, activities are underway for the final phase of commissioning: digging into the ...

Metamaterial significantly enhances chiral nanoparticle signals

The left hand looks like the right hand in the mirror but the left-handed glove does not fit on the right hand. Chirality refers to this property where the object cannot be superimposed on to the mirror image. This property ...
