The world we live on today has undergone dramatic change since it first formed, and time hasn't necessarily been kind. Earth has gained some weight (and a Moon) after a chance collision. A leaky gut led to some confusing internal structures. Here on the surface, mountains keep finding new ways to pop off and destroy surroundings. But scientists are helping us understand all these factors. Learn how in this episode of EVSN, and also hear about our latest tales from the launch pad.

Climate Change Follows the Water
We live on an ever-changing world, and by studying the past, we can better understand our potential futures. In this episode, we follow the water and look at how past periods of glacial melt changed water levels, look into the water and see how pond and sea life add greenhouse gases to the atmosphere, and reflect on a glacier that shrank by 24 km in just 2 years. Oh, and there are also tales from the launch pad!

Giant Black Holes Cosplay as Little Red Dots
The universe is hard enough to figure out without one kind of object dressing up as another, but - just in time for Halloween - researchers have figured out that the Little Red Dot in the early universe just might be massive black holes surrounded in a costume of glowing red gas. Also in this episode, Hyabusa2's amusingly tiny destination, a white dwarf star eating what may be an icy dwarf planet, and tales from the launch pad.

The Black Hole eating star with supernova sized regrets
In this week's episode, we tell the story of a Giant Blue Star that made the terrible, terrible mistake of trying to nibble on its more evolved sibling; it's black hole of a sibling. Folks, don't eat the dark holes in spacetime. We also look at this week's news, including lumpy planets, forming planets, asteroids getting up close and personal, and how Leopard spots are in style for life hunting Mars Scientists. We also have tales from the launch pad.
