Astronomers have discovered a puzzling cosmic anomaly – a supermassive black hole in the galaxy NGC 5084 that appears completely tilted relative to its galactic structure.
The black hole of our Milky Way as seen in polarized light. Astronomers have for the first time been able to measure polarity, a hallmark of magnetic fields, so close to the rim of Sagittarius A*. The lines added to the image indicate the direction of polarization, which is related to the magnetic field around the shadow of the black hole. Credit: EHT Collaboration

When the sun doesn't behave accordingly: the mysterious time gaps in solar flares challenge scientists

  • No comments
Researchers have identified significant time gaps in emissions in solar flares that challenge the accuracy of current models of solar flares, and point to possible alternative energy transfer mechanisms

How a black hole grows

Researchers have developed a method for mapping the central regions around black holes, which contributes to a better understanding of their growth
