Heavy Element NucleoSynthesis In A High mass #Star (narrated video)

Dr. Jim Daly narrates the evolution of a high mass star, describing heavy element nucleosynthesis and how such a star will ultimately end it’s life in a spectacular fashion as a Type-II Core Collapse Supernova. In this video, the evolution of a 15 solar-mass star is depicted from its “0-age” or the point on it’s[…]

Thoughts on a Double-sun Sunset, the #Doomsday Clock and the #FermiParadox

Opinion I’m an Astronomer and Astrophysicist by training and profession and care deeply about all living things, the state of our world and the planet we inhabit. In studying the universe and the natural world most of my life, I have come to learn a few things; among those, I’ve come to learn about the[…]

The #Sun and other #Stars, How They Shine and #Evolve – Part I (#Video)

How does the sun and other stars shine? In this, the first of a multi-part series, Dr. James Daly of Astronomy For Change (https://astronomyforchange.org) teaches us and illustrates how stars, incredibly dynamic and self-regulating, shine and evolve. With this video, we start with the sun as a model and an up-close and personal laboratory to[…]

Podcast – In a galaxy far, far away, KiloNova Explosion From Neutron Star Merger

On 4 December, 2017 Dr. James Daly of Astronomy For Change hosted a public event discussing the landmark discovery and optical counterpart observation of the merger of two Neutron Stars. The discovery was made on 17 August, 2017 using the US-Based LIGO Gravity Wave Telescope Array and the Virgo gravitational wave observatory located near Pisa,[…]

Amateur Astronomer Records Stellar Beacon 80 Million Light Years Distant

On February 21st, in a heretofore unprecedented accomplishment, an amateur astronomer has recorded the “First Light” of a dying star over 80 million light years distant. As described in the Nature article, the first point of contact for the supernova’s photons after traveling 80 million years, a point in the distant past 15 million years[…]

The Star That Wouldn’t Die

A long time ago in a galaxy far, far away…. there was this star that, by all known theories of stellar evolution (the study of how stars are born, live and die), should have died. Many stories in the media lately have described this star as the “Zombie” star since, contrary to what should have[…]

In a galaxy far, far away, KiloNova Explosion From Neutron Star Merger Observed – Gravity Waves Produced

Update to European Southern Observatory To Announce “Unprecedented Astronomical Discovery” Monday, 16 October The European Southern Observatory (ESO) has announced the unprecedented discovery and observation of the optical counterpart to the gravitational wave event observed on 17 August (GW170817) of this year. The full announcement and press event can be watched here: This observation is[…]

Weighing the Milky Way Galaxy

Like early explorers mapping the continents of our globe, astronomers are busy charting the spiral structure of our galaxy, the Milky Way. Using infrared images from NASA’s Spitzer Space Telescope, scientists have discovered that the Milky Way’s elegant spiral structure is dominated by just two arms sweeping off the ends of a central bar of[…]
