Anatomical Dissection of Planetary Nebula Using Hubble Images

Anatomical Dissection of Planetary Nebula Using Hubble Images

Our coverage of last week’s AAS meeting continues with new work on the formation of planetary nebula based on Hubble Space Telescope images. Plus, a massive quasar in the early universe, water ice on Ganymede, a super-puff planet, and plans for taking spectra of Venus’ surface, featuring our guest, PSI scientist Dr. Darby Dyer.

Whole lotta what: Gamma-ray heartbeat heard; Stars with planets have no chemical fingerprint; ‘Oumuamua not made of molecular hydrogen ice

Whole lotta what: Gamma-ray heartbeat heard; Stars with planets have no chemical fingerprint; ‘Oumuamua not made of molecular hydrogen ice

Join us today for a lot of unsatisfying news. First, two objects appear to be pulsing in gamma-rays at the same pace, but they’re 100 light years apart. Next, it turns out that stars with planets look chemically like any other star. And finally, our interstellar visitor, ‘Oumuamua, is NOT made of molecular hydrogen ice.

Second-most distant quasar found and given Hawai’ian name; theoretical axion particles may explain origin of dark matter

Join us today as we look at big news on a big quasar! Pōniuāʻena is the second-most distant quasar ever found, and its existence challenges conventional black hole formation theory. Also, we explain how the theoretical axion particle might be involved in the origin of dark matter.
