Black hole’s corona disappearing act; white dwarf hurtling across Milky Way; SDSS fills in gap in expansion history; new image of CMB continues age debate; using science to analyze art

Jul 20, 2020 | Cosmology, Daily Space, Rockets, Supermassive Black Holes, White Dwarfs

Join us today as we examine one possible reason a black hole’s corona may have disappeared. Be on the lookout for a runaway white dwarf whose supernova sent it hurtling across the Milky Way. We take a look at new survey results that fill in an 11-billion-year gap in the expansion of the universe. A new image of the cosmic microwave background suggests the universe is 13.77 billion years old, give or take 40 million years. And as a fun bonus, scientists use celestial sleuthing on a Vermeer painting to determine when it was actually painted.

Exposed planetary core discovered; neutrinos may come from SMBHs; filaments around galaxy cluster Abell 2255; LIGO reveals “spooky popcorn”

Jul 2, 2020 | Daily Space, Exoplanets, Galaxies, Physics, Quantum

Join us today as we talk about the first exposed planetary core ever discovered. We examine research that neutrinos may come from supermassive black holes. We look at the filaments found in the halo of galaxy cluster Abell 2255. And we find out that LIGO’s mirrors can vibrate due to quantum noise. Plus an interview with Dr. Matthew Graham of Caltech.

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

Jun 29, 2020 | Cosmology, Daily Space, Dark Matter, Gemini South, Quasar, Supermassive Black Holes

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.

Gravitational wave event leads to detection of object in “mass gap” and corresponding light detection

Jun 25, 2020 | Daily Space, Neutron Stars / Pulsars, Supermassive Black Holes

For today, both stories are related to the detection of gravitational wave events and are believed to be caused by the merger of massive objects far off in the universe.

X-ray view of the sky; Hubble images planetary nebulae; Planets form more quickly than previously thought

Jun 19, 2020 | Daily Space, ESA, Exoplanets, Galaxies, Milky Way, Planetary Nebulae

Join us today as we take a look at an amazing all-sky view done in x-ray wavelengths. We also get to see gorgeous images Hubble took of planetary nebulae that show wild processes going on. And finally, we learn that planets form much more quickly than previously thought.

Fermi bubbles and the Magellanic Stream; Fast Radio Bursts and their host galaxies; Mars and its former ring

Jun 4, 2020 | AAS, Cosmology, Daily Space, Galaxies, Mars, Milky Way

Join us today while we take a look at Fermi bubbles and their relationship to the Magellanic Stream. We examine new research on the origin galaxies of some Fast Radio Bursts. And we learn about how Mars’ moon Deimos provided evidence that Mars once had a ring.
