Nova explosions, which were thought until now to be relatively simple, are actually turning out to be very different. An ...

Astronomers have long struggled to capture the true nature of stellar nova explosions. However, thanks to cutting-edge ...

Fringe conference can be traced to the automatic processing of fringe patterns. The term “patterns” evokes an image of flowing lines elegantly wrapped around surface contours. However, automatic ...

Astronomers have obtained remarkably detailed images of two stellar explosions -- called novae -- just days after they began.

Almost a century ago the concept of measuring surface roughness started as a way to stop disputes and uncertainty between buyers and manufacturers. Today, it is a common identifier that is utilized ...

Manufacturing a precision surface requires a balance between satisfying the optimum quality requirements at the minimum cost. Steve Martinek summarizes the challenges of increasing the precision ...

When Hanbury Brown and Twiss (HBT) first proposed that intensity fluctuations of light measured at two different locations carry information on the size of the light source, they met with strong ...

The Event Horizon Telescope has accomplished what no other telescope or telescope array has ever done: imaged the event horizon of a black hole directly. A team of more than 200 scientists using data ...

This image compares data from two Iceye Synthetic Aperture Radar images. Changes in the vertical height of the surface appear black. Areas without changes are depicted in white. Credit: Iceye SAN ...

Microlenses have many applications, such as coupling light into fiber optics, enhancing light source uniformity in microdisplays, and focusing light onto imaging sensors in mobile phone cameras.

New high-resolution images show that novae are anything but simple stellar fireworks. One exploded with multiple gas streams ...
