To date, close to 30,000 satellites have been launched into Earth's orbit, leading to mounting concerns over the debris created when they collide. In a new analysis posted to the preprint server arXiv, Hugh Lewis of the University ...
For more than two decades, the quasar PHL 1811 has been considered the prototype of a rare class of "intrinsically X-ray weak" quasars, thought to produce unusually little X-ray radiation. But in 2024, the Einstein Probe ...
Astronomers have captured an unprecedented image of a cosmic recycling project in progress—fragments of a dying star being busted up, stripped and absorbed into interstellar space.
