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

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.

RAVE spectroscopic survey releases final data set; “central engine” of a solar flare characterized; conveyor belt of material seen feeding young star system from parent cloud

RAVE spectroscopic survey releases final data set; “central engine” of a solar flare characterized; conveyor belt of material seen feeding young star system from parent cloud

Join us today while we take a look at the final data set released by the RAVE spectroscopic survey of stars in the southern hemisphere. Also, scientists at Harvard’s CfA have characterized the “central engine” of a solar flare from our Sun. And finally, scientists in Europe observed a parent cloud feeding material to a pair of young stars.

Galaxies have magnetic fields, too; ultraviolet flash spotted with supernova; multi-planet system directly imaged; new method finds ‘lost’ worlds

Galaxies have magnetic fields, too; ultraviolet flash spotted with supernova; multi-planet system directly imaged; new method finds ‘lost’ worlds

Join us today as we learn that galaxies have magnetic fields, too. Also, scientists are excited to catch the ultraviolet flash of a type Ia supernova and directly image a multi-planet extrasolar system. Finally, researchers have developed a new method for finding “lost” worlds in NASA TESS data (but no dinosaurs, thankfully).
