Start With a Bang –

Here on Earth, the Sun is our primary source of light, heat and energy. But it also poses a serious threat to human civilization.

This illustration shows a massive space weather event, larger than a typical solar flare, known as a surface mass ejection. Although IMMs have the ability to completely destroy a planet, fortunately they are limited to the emergence of red supergiants, a class of stars that will never include our Sun or anything it will evolve into.

Key recommendations

  • The sun shines with a constant energy of 400 septillion joules every second, making life as we know it possible on planet Earth.
  • But the Sun, despite its benefits, also emits flares, coronal mass ejections, and other types of space weather, with potentially catastrophic consequences for human civilization.
  • We’ve gotten away with being complacent about the severity of this threat so far, but that won’t last long. Here’s what everyone should know about the threat of the Sun.

For life on Earth, there is no source of energy more important than the Sun; without it, it is doubtful that life would have appeared on Earth, and it certainly would not have evolved to give rise to the wild diversity of biological organisms seen today. But the Sun is more than a constant source of heat and light; it also emits particles, and there’s a darker side to that activity: flares, coronal mass ejections, and the threats this space weather poses to living planets like ours.

It turns out that for technologically advanced civilizations like ours, the threats emanating from the Sun are far greater and more dangerous than at any previous time in Earth’s history, and despite our knowledge of what it can do Earth Sun, we are woefully unprepared for the inevitable. Fortunately, it’s not just people studying it, but many of them are fighting and advocating for solutions and planetary protection, including Sierra Solter, a plasma physicist specializing in solar plasmas, who joins us on this edition of the Starts With A Bang podcast . .

Welcome to a glorious 2023 and let’s learn the necessary lessons of what needs to be done before we are left with the sad alternative of simply picking up the pieces!

The very dust that blocks our view of distant and bright objects in the Universe is responsible for our entire existence.

Supermassive black holes at the center of galaxies gobble up any matter that ventures too close, becoming active. Here’s how it works.

The stars closest to us hold the key to unlocking the possibilities of life in star systems throughout the Universe.

In 1990, we knew of no planets beyond our Solar System. Today, with over 5000, we are deep in the weeds as they form.

Our model of the Universe, dominated by dark matter and dark energy, explains almost everything we see. Close. Here is what remains.

The most popular songs are about love and heartache. But some great songs—albeit understated and maybe a little weird—are about the cities we love.
