Scientists propose a modified cosmological model that challenges the existence of dark matter and dark energy.
Quantum tunneling may have ruled out a popular theory of dark matter
The composition of dark matter remains a mystery, but a new theory involving quantum tunneling may have eliminated some candidates.
Could dark matter be measured around black holes?
Dark matter could be aggregating around black holes, providing a possible means of indirectly measuring its properties.
Searching for the true theory of electromagnetism
Scientists probe cosmic microwave background and black hole radiation to test our understanding of electromagnetism.
Dying star caught by astronomers enjoying planet-sized last meal
The observations of the death-row star and an unfortunate planet give us an advanced preview of Earth’s final fate.
How close-ups of Mars’ moon Deimos are a game-changer for the UAE
“People in the Emirates think differently now, school students dream of going to space, of being a scientist. That’s the real goal.”
Observations shed light on neutron star paradox
Astronomers have observed neutron stars that emit more energy than is theoretically possible, and now an explanation might be in the works.
Modified theory of gravity eliminates the need for dark energy
Many physicists are still skeptical that dark energy can fully explain gravity, and are therefore exploring alternative theories.
Galaxy clusters help confirm the Standard Model of Cosmology
Comparing simulated X-ray emissions from galaxy clusters to real observations provides support for the Standard Model of Cosmology.
Microbes may be key to making space exploration sustainable
Nine different ways of using technologies based on microbes that can make space research more circular and generally more sustainable.
