Astronomers used a decade of observations of a distant blazar to show that turbulence in the Milky Way’s interstellar medium adds its own distortions to radio signals from deep space.

A decade-long UCLA-led search using the Green Bank Telescope examined radio emissions from more than 70,000 stars and planetary systems. It found no confirmed artificial narrowband signals, but it did deliver one of the

A new historical review revisits the first dedicated SETI search beyond the Solar System and the equation that gave scientists a framework for thinking about intelligent life in the universe.

Using the Very Large Baseline Array at 5 GHz, astronomers measured the masses of heavily obscured young stars inside the Orion Nebula’s dusty star-forming environment.

A study of nearly 200 millisecond pulsars suggests some radio signals originate not just near the stellar surface but also from much farther out, in regions associated with gamma-ray emission.

A new paper argues that conventional SETI research has been too narrowly focused on radio and microwave frequencies for decades, and that a broader search across the full electromagnetic spectrum could dramatically improve the odds of detecting alien signals.

SETI researchers say artificial intelligence tools could dramatically improve the chances of detecting extraterrestrial signals by sifting through vast radio data more effectively.

The LOFAR telescope array has completed the most comprehensive radio survey of the universe ever conducted, mapping 13.7 million cosmic sources including supermassive black holes, merging galaxies, and supernova remnants. The survey opens a new window on phenomena invisible to optical telescopes.

Columbia University scientists working with the Breakthrough Listen project have identified a millisecond pulsar candidate spinning at 8.19 milliseconds near Sagittarius A*. If confirmed, the discovery could provide a powerful new tool for testing Einstein's general relativity under extreme gravitational conditions.
