ESA greenlights LISA, a space-based observatory poised to detect gravitational waves across space and time.
James Webb Telescope deepens the mystery of the expansion of the Universe
It’s looking less and less likely that the Hubble tension is a result of observational errors.
Subaru Telescope shatters limit, observes supermassive black holes in the early Universe
Scientists have only observed supermassive black holes one billion years after the Big Bang, but astrophysicists have now breached this barrier.
Astronomers observe a galaxy’s magnetic field in the very early Universe
The galaxy 9io9 is seen as it was when the cosmos was just 2.5 billion years old, making this the earliest galactic magnetic field ever observed.
Time ran slowly in the early Universe, just as Einstein predicted
Using quasars as ticking cosmic clocks, scientists took a journey back in time, discovering time progressed five times slower just after the Big Bang.
Explaining the “universe breaker” galaxies discovered by the James Webb Telescope
Astronomers report recent observation of six massive galaxies that according to our current understanding of the Universe should not exist at all.
Explaining the Universe’s accelerated expansion without dark energy
A modification to the theory of general relativity makes it consistent with observable astronomical data without the need for dark energy.
General relativity may need tweaking on the grand scale of the Universe
Conflict between theory and observational evidence suggests a missing ingredient in our understanding of the early Universe.
Evolution of the Universe simulated in a lab
Using the motion of sound waves through a superfluid liquid, scientists can model the Universe’s evolution on a reasonable time scale.
Is the Universe running out of stars?
Astronomers are discovering that the rate of star formation in the universe is dropping, and they want to know why.
