Researchers use observations of 65,951 giant pulses to investigate the pulse properties of the pulsar at the center of the Crab Nebula, a famous supernova remnant.
Dynamical friction due to the presence of a dark matter density spike may account for the observed rate of orbital decay of a supermassive black hole binary.
Dust plays an important role in creating Mercury’s tenuous exosphere and weathering its surface; new measurements from BepiColombo will advance our understanding of dust’s effects on Mercury.
A global network of robotic telescopes helps test a new way of measuring oscillation modes of massive stars; successful measurements of these modes may unlock these stars’ interior structures.
The interstellar media of dwarf galaxies — defined in this work as galaxies with total stellar mass less than about 3 billion times the mass of the Sun — haven’t changed much over the past 7.8 billion years.
If current or future spacecraft cross a solar current sheet, it would give researchers entirely new insight into these structures, which are key to understanding solar eruptions.
