It’s a Star-Eat-Planet Universe

One of the most mystifying planets to many of us are the hot Jupiters. These massive worlds have orbits smaller than Mercury’s and in some cases are so close to their stars that starlight is pushing mass off the planet or the planet is raising tides on the star. Exactly how you snuggle a planet next to a star and have it stay there is … confusing. And now we know, not all the planets succeed in getting close without falling in. Back in 2019, a star about 12,000 light years from Earth, in a particularly crowded part of the sky, was observed by the NEOWISE mission to start shining with a lot...

Ryugu Sample Supports Invading Life

Ryugu samples showing signs of bacteria contamination. Trying to understand the evolution of planets and life is really a driving motivation for a lot of science and science fiction. Landing squarely in the “I think I read a horror story about this,” scientists found...

Io Doesn’t Actually Have a Gooey Center

Collapsed volcanoes form large, dark spots on Io's surface, NASA/JPL/USGS One of our greatest frustrations as a science, is we astronomical and planetary scientists can’t do the same kind of experiments that other kinds of scientists get to do. We look at things from...

Modern Melt

Our Earth is currently working its way toward being the exact opposite of a snowball Earth as we see glaciers and ice caps receding across the planet. This is fundamentally changing our landscape and how we as humans interact with that landscape.  These changes...

Snowball Earth. Credit: NASA Our planet has been driven to environmental extremes at many times in its history, and many plants and animals - including humans - have demonstrated they can survive less than ideal conditions. The last major ice age hit its peak 20 to 26...

Dinosaurs Thrived After Ice

Archaeopteryx Credit: Peter Montgomery Jupiter’s moon Io is the most volcanic object in our solar system today, but our planet gave Io a run for its money more than 200 million years ago. At that point in our planet's history, our world was dominated by the Triassic...

Volcanic Moon Orbiting Distant World

Volcanic Moon Orbiting Distant World

Let’s look at a world 635 lightyears away that just might have a fiery moon of volcanic goodness. To be honest, every aspect of this system is hot. The star is similar our Sun, but the planet is on an 2.8 day orbit around that star, and this orbit makes Mercury look...
