A pulsar's apparent slowdown reveals a rare stellar trio
Pulsars are rapidly rotating neutron stars, the extremely dense cores left behind when massive stars explode. Astrophysicists have recently observed a pulsar rotating over 300 times per second that appeared to be slowing ...
The sun may have stripped away meters of interstellar comet 3I/ATLAS
The interstellar comet 3I/ATLAS brought material from another planetary system within reach of our telescopes, but reading its chemistry poses a problem. Energetic particles encountered during its journey through space may ...
Giant canyon on Mars is still tectonically active today
Scientists at Columbia University and Imperial College London have found that the largest canyon system in the solar system is still active and shaping Mars today, billions of years after it first formed.
