This image was taken from the International Space Station on March 8, 2004, from a position off the coast of Mauritania. (NASA/DVIDS) The Pentagon is looking for cheap commercial satellites that can ...

Abstract: Overcoming the angular resolution limitations imposed by antenna apertures remains a critical challenge in radar systems. The nonlinear wavefront modulation technique enables angular ...

This new map is not only the most detailed view of the universe’s invisible scaffolding to date, it also allows astronomers to look deeper into cosmic history. Reading time 3 minutes Dark matter—the ...

Abstract: Sparse array designs have focused mostly on angular resolution (mainlobe width), peak sidelobe level and directivity factor of virtual arrays for multiple-input multiple-output (MIMO) radar.

In a recent study, researchers from China have developed a chip-scale LiDAR system that mimics the human eye's foveation by dynamically concentrating high-resolution sensing on regions of interest ...

The only major difference between the sun and the stars we see at night is that the sun happens to be close to us—which is advantageous, assuming you enjoy being alive. Astronomers enjoy this as well ...

Dual-triangular electrode layout with MXene/silicone nanocomposite achieves quite competitive omnidirectional force detection (threshold: 0.024 N) and angular resolution (5°) using only two electrodes ...

People often think of holidays as joyful, but for many, this time of year can make grief feel even stronger. This can occur, for instance, when someone is suffering from ambiguous loss — a kind of ...

Radar is a cost-effective and dependable automotive sensor solution, even in challenging conditions such as fog, darkness, and rain. How size and cost are significant constraints on radar resolution ...

Juno would offer ~20-24x better angular resolution due to proximity (distance ratio ~24:1), enabling finer details of extended features like jets or tail asymmetry, if the coma is active. Juno excels ...

Republican lawmakers plan to introduce legislation to revoke the federal charter of the National Education Association (NEA) over concerns about its political priorities. North Carolina Rep. Mark ...
