Twenty years ago, scientists were shocked to realize that our universe is not only expanding, but that it’s expanding faster over time. Pinning down the…
The single most important puzzle in today’s cosmology (the study of the universe as a whole) can be summarized in one question: How old is…
The word “HAZMAT” describes substances that pose a risk to the environment, or even to life itself. Imagine the term being applied to entire planets,…
Collimated jets provide astronomers with some of the most powerful evidence that a supermassive black hole lurks in the heart of most galaxies. Some of…
A RUDN physicist demonstrated how to describe the shape of any symmetrical wormhole – a black hole that theoretically can be a kind of a…
On October 16, 2017, an international group of astronomers and physicists excitedly reported the first simultaneous detection of light and gravitational waves from the same…
Most galaxies host a supermassive black hole (SMBH) at their nucleus (a supermassive black hole is one whose mass exceeds a million solar-masses.) A key…
An international team of scientists studying what amounts to a computer-simulated “pulsar in a box” are gaining a more detailed understanding of the complex, high-energy…
Astronomers from Lund University in Sweden have now found the explanation to a recent mystery at the centre of the Milky Way galaxy: the high…
Astronomers typically study objects that are visible night after night or explode suddenly, like supernovas, but Casey Law is scouring vast amounts of data in…
Researchers in Canada, the United States and Europe have developed a new way to remotely measure Earth’s magnetic field—by zapping a layer of sodium atoms…
A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions…
For one brief shining moment after the 2015 detection of gravitational waves from colliding black holes, astronomers held out hope that the universe’s mysterious dark…
Researchers have found white dwarf stars with masses close to the maximum stable mass (called the Chandrasekhar mass) are likely to produce large amounts of…
Like our sun, distant stars are rotating spheres of hot gas. Stars, however, do not rotate like solid spheres: regions at different latitudes rotate at…
Researchers at NYU Abu Dhabi reveal that sun-like stars rotate up to two and a half times faster at the equator than at higher latitudes,…
A team of scientists has calculated the strength of the material deep inside the crust of neutron stars and found it to be the strongest…
Black holes form when stars die, allowing the matter in them to collapse into an extremely dense object from which not even light can escape….
