Jocelyn Bell Burnell discovered pulsars (manifesting as periodic “scruff” on the chart records) nearly six decades ago (28th Nov 1967) as a graduate student in radio astronomy at Cambridge.

#OTD in 1967, Jocelyn Bell Burnell discovered pulsars, the rapidly spinning cores of dead stars that emit pulses of light with ultraprecise timing. Decades later, we’re still learning about what matter is like under such extreme conditions: go.nasa.gov/4ljxtCn

Oxford Professor Dame Jocelyn Bell-Burnell discovered the first pulsar in 1967 - a discovery so important in our understanding of the universe that it would earn a Nobel Prize.

Initial results from IXPE (NASA/ASI mission) leverage the power of X-ray polarimetry to constrain the accretion geometry in X-ray pulsar Her X-1. The results also indicate a misalignment of the spin, magnetic & orbital axes. @doroshv3, Poutanen et al.: nature.com/articles/s41550-0…
