A mystery interstellar object discovered last week is likely to be the oldest comet ever seen—possibly predating our solar ...

An efficient scheme with phase compensation and amplitude optimization has been proposed to improve the electromagnetic performance deteriorated by the radome. Instead of altering the configuration of ...

Astronomers have spotted a new interstellar object — the third of its kind ever seen — shooting towards us through the solar ...

The use of multiple antennas in radar systems that establish antenna arrays in transmitter (Tx) and receiver (Rx) has become of current interest. The Phased-MIMO radar (PMIMO) combines simultaneously ...

New observations from England’s e-MERLIN interferometer telescope array display cosmic pebbles that will one day grow into ...

Astronomers have spotted centimeter-sized “pebbles” swirling around two infant stars 450 light-years away, revealing the raw ...

Located billions of light-years away, the "Cosmic Owl" is a pair of colliding ring galaxies spotted by the JWST. It's also an ...

PhoSim simulates the atmosphere, including air turbulence, as well as distortions from the shape of the telescope’s mirrors and the electrical properties of the sensors. The photons are propagated ...

Astronomers have turned the Atacama Large Millimeter/submillimeter Array (ALMA) into a time machine to peer back in cosmic time to 1 billion years after the Big Bang.

A fascinating glimpse into how a solar system like our own is born has been revealed with the detection of planet-forming ...
