The universe is expanding uniformly according to research led by University College London (UCL). The researchers studied the cosmic microwave background (CMB) which is the remnant radiation from the Big Bang. It shows the universe expands the same way in all directions, supporting the assumptions made in cosmologists’ standard model of the universe.
Now that scientists have confirmed the existence of gravitational waves, a NASA team using a balloon-borne observatory is set to search for a predicted signature of primordial gravitational waves that would prove the infant universe expanded far faster than the speed of light and began growing exponentially almost instantaneously after the Big Bang.
Using new images that show unprecedented detail, scientists have found that material rotating around a very young protostar probably has dragged in and twisted magnetic fields from the larger area surrounding the star. The discovery, made with the Very Large Array radio telescope, has important implications for how dusty discs — the raw material for planet formation — grow around young stars.
Fast radio bursts (FRBs), brief yet brilliant eruptions of cosmic radio waves, have baffled astronomers since they were first reported nearly a decade ago. Though they appear to come from the distant universe, none of these enigmatic events has revealed more than the slimmest details about how and where it formed, until now.
