If a star is a million light years away and you see it explode today didn't the explosion take place a million years ago Therefore what condition and where would the star be today?

Isn't that a truly fascinating question? The reality is that we do not know, and we have no possible way of knowing. The speed of light seems to be a limiting factor, and many interesting things happen when it is an important part of an observation like this one.

Yes, you are correct that the light from the star's explosion took a million years to reach Earth, so the explosion actually occurred a million years ago. In the present day, the star would no longer exist at the location where the explosion occurred. The remnants of the explosion may have expanded and dispersed over time, or the star may have evolved into a different stage in its life cycle.

Was the Cambrian explosion a volcanic eruption?
No, the Cambrian explosion was not a volcanic eruption. It was a period of rapid diversification of multicellular lifeforms that occurred around 541 million years ago, marking the beginning of the Paleozoic era.
When was the Cambrian period according to our geologic time scale?
People think "explosion that must have happened in a second." It didn't. The Cambrian Explosion started approximately 542 million years ago, triggered by an suddenly-oxygen-rich atmosphere and the end of glaciation, and lasted for about 12 million years. This is VERY long.

Why did the Cambrian explosion may not have been an explosion?
The term "Cambrian explosion" is a bit misleading because the diversification of early metazoans actually occurred over tens of millions of years, rather than a sudden event. Some scientists prefer to refer to it as the "Cambrian radiation" to better capture the gradual nature of the process. This prolonged period of diversification resulted in the emergence of a wide range of complex multicellular organisms.

What's the total energy emitted by the brightest nova explosion?
The total energy emitted by the brightest nova explosions is typically around 10^41 to 10^44 joules, which is equivalent to a few thousand times the total energy output of the sun in a year. Novae are caused by the explosive ignition of accumulated hydrogen on the surface of a white dwarf star in a binary system.
