Short gamma-ray burst’s afterglow detected; young star found with spiral disk; red giants with starspots rotate quickly; machine learning helps predict survivability of planetary systems

Jul 14, 2020 | Cosmology, Daily Space, Exoplanets, Gemini North, Stars

First, we look at how researchers detected the afterglow of a short gamma ray burst a mere 3.8 billion years after the Big Bang. Then we examine the discoveries of a spiral structure in the disk of a young, heavy star and how red giant stars with large starspots spin faster than those without. And finally, we see how machine learning can be used to predict what planetary systems are most likely to survive.

Asymmetric neutron binary star system discovered; Planet 9 could be a black hole (really); Mars Curiosity and InSight catchup; Comet NEOWISE

Today’s news comes from all over and starts with a pair of pulsars headed toward merger in 500 million years. This system will help us understand August 2017 observations of a neutron star merger. From one high mass object to another, we turn to look at Avi Loeb’s new idea that Planet Nine might actually be a primordial black hole, what to look for if it is. We also catch up on Mars and its current robot explorers: InSight and Curiosity. Finally, we discuss how to see naked eye comet NEOWISE in the evening sky.

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

Jul 3, 2020 | Cosmology, Daily Space, Exoplanets, Observatories, Star Forming Region, Uncategorized

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.

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.

Massive star disappears; Symbiotic nova produces burst of gamma rays; “Capture the Dark” photography contest winners announced

Jun 30, 2020 | Daily Space, Stars, Supernovae

Join us today for our top story: a massive star has disappeared, probably due to dust but maybe not. Also, we explain how a symbiotic nova occurs and produces gamma rays. Finally, we are pleased to share some of the winners and runners up in the “Capture the Dark” photography contest from the International Dark Sky Association.

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.
