According to a new study, middle-aged stars can undergo a midlife crisis of their own kind, experiencing drastic interruptions in their activity and rotation rates at about the same age as the Sun.
The eROSITA space telescope has revealed its first results with tentative hints at a detailed map of the Universe’s black holes and neutron stars.

Black holes are not what they consume. Einstein’s theory of general relativity forecasts that regardless of what a black hole gobbles up, its external properties are based only on its rotation, mass and electric charge.
The shortest-ever gamma-ray burst (GRB) caused due to the collapse of a massive star has been discovered by astronomers.
Black holes are detected by the gravitational wave signal they emit upon colliding with other black holes. Such black holes could be the product of much earlier parent collisions.
The Australian Government offers financial support to scientists at The Australian National University (ANU), helping Canberra reach a step ahead to being Australia’s home to deep space laser communication.
Using information obtained from around a dozen earthquakes detected on Mars by the Very Broad Band SEIS seismometer, developed in France, the international team of NASA's InSight mission has unveiled the internal structure of Mars.
Nuclear fusion offers the potential for a safe, clean and abundant energy source.
In the depths of space, there are celestial bodies where extreme conditions prevail: Rapidly rotating neutron stars generate super-strong magnetic fields.
Astronomers conducted an elaborate and sensitive survey of a large portion of the Milky Way galaxy using two of the world’s most powerful radio telescopes. They were able to detect previously unseen tracers of huge star formation, a process that controls galactic ecosystems.
For the first time, astronomers have detected the existence of a disk around a planet, present outside the solar system, with the help of the Atacama Large Millimeter/submillimeter Array (ALMA).
Researchers have discovered a "layer" Hall effect in a solid state chip constructed of antiferromagnetic manganese bismuth telluride, a finding that signals a much sought-after topological Axion insulating state, the team reports in the current edition of the journal Nature.
At low temperatures, certain materials lose their electrical resistance and conduct electricity without any loss - this phenomenon of superconductivity has been known since 1911, but it is still not fully understood.
As per the new cosmological models, huge spiral galaxies like the Milky Way expanded by absorbing smaller galaxies, by a kind of galactic cannibalism.
A research group from Los Alamos National Laboratory has suggested that modulated quantum metasurfaces have the ability to regulate all properties of photonic qubits, a discovery that could influence the fields of quantum information, sensing, and imaging, communications, as well as momentum and energy harvesting.
