Normally found only in heavy metal bands or certain post-apocalyptic films, a "flame-throwing guitar" has now been spotted moving through space. Astronomers have captured movies of this extreme cosmic object using NASA's ...
An international team of astronomers has discovered an instance of two galaxies aligned in a way where their gravity acts as a compound lens. The group has written a paper describing the findings and posted it on the arXiv ...
The Australian government is developing legislation that will ban children under 16 from social media. There has been a huge public debate about whether there is sufficient direct evidence of harm to introduce this regulation.
Supermassive black holes (SMBHs) can have billions of solar masses, and observational evidence suggests that all large galaxies have one at their centers. However, the JWST has revealed a foundational cosmic mystery.
Why is the expansion of our universe accelerating? Twenty-five years after its discovery, this phenomenon remains one of the greatest scientific mysteries. Solving it involves testing the fundamental laws of physics, including ...
The theory of special relativity is rife with counterintuitive and surprising effects, the most famous of which are length contraction and time dilation. If an object travels at a relative speed, which is a non-negligible ...
Among its other notable achievements and puzzles, the James Webb Space Telescope (JWST) has found a larger number of bright galaxies in the distant universe than was expected. While scientists are still debating the excess, ...
A team of researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO), in the U.S., has developed what they describe as a squeezed light system to improve detection sensitivity.
Given how unfathomably large the universe is, it is perhaps understandable that we haven't yet cracked all its secrets. But there are actually some pretty basic features, ones we used to think we could explain, that cosmologists ...
In February 2016, scientists at the Laser Interferometer Gravitational-wave Observatory (LIGO) confirmed they made the first-ever detection of gravitational waves (GWs). These events occur when massive objects like neutron ...
