Scientists believe that in the very early universe, everything was incredibly tiny, chaotic, and full of random energy ripples, known as quantum foam. It was a state where spacetime was unstable, and ...

As the complexity of space missions—such as Earth–Moon transport and deep-space exploration—continues to increase, the classical Keplerian two-body model can no longer meet the precision requirements ...

Exploring Saturn's largest moon, Titan, presents unique orbital challenges due to its dense atmosphere, gravitational perturbations, and limited sunlight. A new study proposes an innovative satellite ...

Astronomers using the National Science Foundation’s Green Bank Telescope (GBT) have discovered a unique stellar system of two white dwarf stars and a superdense neutron star, all packed within a space ...

Albert Einstein theorized that as heavy objects move through space and time, they create ripple effects in the fabric of our universe. Now an international team of scientists have detected new ...

The Arecibo Observatory in Puerto Rico, one of the radio telescopes used to detect the pulses from pulsars in the new research. The telescope started to fall apart in 2020 and was decommisioned.

In September 2015, a vibration lasting just one-fifth of a second changed the history of physics. It was the first direct detection of gravitational waves — perturbations in the geometry of space-time ...

LISA is set to revolutionize our understanding of the gravitational universe and the interactions that make the entire cosmos turn. Reading time 6 minutes LISA, a $1.6 billion gravitational wave ...

On May 21, 2019, the mass of eight suns disappeared. In a universe like ours, in which mass and energy are conserved, mass cannot disappear without consequences: and so it went that, as two distant ...

General Relativity continues to provide a robust framework for understanding the interplay between gravitational waves and the cosmological constant. Gravitational waves—ripples in the fabric of ...

Earth's cosmic neighbourhood is more dynamic than imagined, hosting temporary 'mini-moons' captured by gravity and ...
