In today’s bite, we explore a new method for studying how structure grows during the Universe’s formative teenage years, using rebellious dropout galaxies and peer-pressured CMB photons.
As a pulsar speeds through the interstellar medium, it leaves behind a long, radio-emitting tail shaped by ram pressure. In the Lighthouse Nebula, however, the X-ray emission and radio streaks show unexpected orientations, offering clues to how cosmic rays escape and trace surrounding magnetic fields.
The dynamics of our galaxy become evermore complicated as today’s authors discover a mysterious wave propagating out towards its outskirts.
Not just the right temperature for water, but the right chemical recipe: only planets formed in a narrow nitrogen-, phosphorus-, and oxygen-balanced “Goldilocks” zone may keep life’s key ingredients available at their surface.
Can a sneezing ant destroy a black hole? Regge and Wheeler set out to find out.
We use bottles, and sometimes a Brita, but how do planets store their water? The authors of today’s paper made a model to find out, and to evaluate whether certain planets are good at hanging on to their water or not.
