Black hole signatures, planetary nebulae, and… Bennu

Black hole signatures, planetary nebulae, and… Bennu

Astrophysicists have finally figured out how to tell neutron stars apart from black holes by finding the signature of the event horizon. Another team discovered that planetary nebulae likely get their unique shapes due to binary systems. And we present some updates on the origin of rocks (and rocks and rocks and pebbles) on Bennu. Same with Ryugu, but we don’t hate Ryugu.

Free-flowing water on ancient Mars? Not so fast! Plus a black hole fails to prevent star formation and unequal neutron stars colliding may be noisy.

Free-flowing water on ancient Mars? Not so fast! Plus a black hole fails to prevent star formation and unequal neutron stars colliding may be noisy.

Join us today as we talk about newly released research that suggests the waters on ancient Mars were subglacial and not free-flowing. Also, a black hole goes dormant and star formation goes wild. Meanwhile, computer models show that unequal neutron stars colliding may cause a big “bang” that can be detected on Earth.

Quantum effects observed in white dwarfs; machine learning helps find low-oxygen-abundance galaxy; signs of possible neutron star in SN 1987A; pair of recent meteorites found in Australia

Join us today as we look at how quantum mechanics and Einstein’s theory of general relativity work together in white dwarfs. Machine learning is used to find a galaxy with an extremely low abundance of oxygen. Scientists find signs of a neutron star in supernova 1987A. And researchers managed to locate two recently arrived meteorites in Australia with the help of fireball detection cameras.
