An international team from China and Italy has reported a possible cosmic encore to the landmark 2017 multi-messenger discovery. In November 2024, the LIGO-Virgo-KAGRA observatories detected ...

Astronomers have spotted what may be one of the universe’s earliest barred spiral galaxies — a striking cosmic structure forming just 2 billion years after the Big Bang. The galaxy, COSMOS-74706, ...

For years, cosmologists have argued over a simple question with an awkward answer: How fast is the universe expanding right now? The expansion rate, called the Hubble constant, ought to come out the ...

Last year, our most detailed map of the universe yet suggested our understanding of dark energy has been wrong for decades. The shock result is reigniting the search for a better cosmic story ...

Scientists propose a gravitational-wave method called the stochastic standard siren to measure the Hubble constant, offering an independent way to examine the universe’s expansion and the Hubble ...

A supermassive black hole roughly 11.6 billion light-years from Earth is consuming matter at 13 times the theoretical maximum rate, forcing astrophysicists to reconsider how these cosmic giants grew ...

Astronomers working with data from the Hobby-Eberly Telescope Dark Energy Experiment, known as HETDEX, say they have produced ...

The conceptual architecture of black holes has undergone a radical transformation between 2024 and 2026, transitioning from the classical bottomless pits of general relativity to the intricate ...

Scientists gathered in a conference earlier this year in an effort to solve the issue of satellite streaks ruining a powerful ...

The icy ballet of stone upon ice makes curling one of the most intriguing sports of the Winter Olympics. But scientists still haven't quite figured out the physics of how they move. For a sport that ...
