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.

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.

Cosmic reionization caught in the act; Exoplanet pair found using ground-based telescope; Celebrate the Fourth of July with two images of cosmic fireworks

Join us today as we talk some more about cosmic reionization and the mounting evidence it occurred very early in the Universe. We also look at two exoplanets, found using a ground-based telescope, that are gravitationally interacting. And we celebrate the Fourth of July here in the United States with some newly released images of cosmic fireworks.
