Astronomers used gravitational lensing to detect a supernova 10 billion light-years away, providing spatially separated images that help study cosmic expansion and early Universe events.

After nine years of scanning the sky, the Wilkinson Microwave Anisotropy Probe (WMAP) space mission has concluded its observations of the cosmic microwave background, the oldest light in the universe.

The LIGO-Virgo-KAGRA (LVK) collaboration recently began a new observing run that promises to take gravitational-wave astronomy to the next level. According to scientists from across the ...

Observing the spectral features of distant objects can allow us to reveal the history of the early universe, especially how the universe evolved after it became transparent 380,000 years after the Big ...

When the SpIRIT CubeSat rode into orbit on a SpaceX Falcon 9 in December 2023, it carried a very massive passenger along. Cramped inside the shoebox-sized satellite is the HERMES detector, an ...

In his 1948 book, The Stars in Our Heaven, Peter Lum wrote: “The Swan of Heaven is a long-necked bird in full flight down the Milky Way. He is … by far the most magnificent of the feathered creatures ...

Artist's illustration of a galaxy in the early universe that is very dusty and shows the first signs of a rotationally supported disk. The red color represents gas, and blue/brown represents dust as ...

Compared with the ultimate goals of the Starshot project, observing the universe using relativistic cameras should be easier. Aiming the camera wouldn’t be a concern, because it could get interesting ...
