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...

The Universe sometimes likes to mock us. Such is the case with exoplanets. Once upon a time, researchers would sagely say, “Solar Systems like Tatooine, with twin stars, likely don’t exist.” The thing is, this was based on models that relied on limits created with...

Venus Volcanism is Erupting in the Literature

Another big topic of discussion at LPSC seemed to be Venus. I say "seemed" because I’m sure the actual big topic of discussion was proposed budget cuts, which could be as much as 50%, but there was no definitive information on budget cuts, so that is more a big topic...

Talk of Mars has been seeping into just about every area of media, as rumors swirl that NASA’s current plans to return humans to the Moon will be replaced with plans to fly directly to Mars. Given that we can’t currently keep people alive on Mars, I’m really hoping...

Protecting Historic Sites on Earth, Moon, and Mars

Dominion Observatory in Ottawa Our planet is dotted with old observatories and astronomical research centers that are no longer capable of doing science. Either their equipment is too small, their skies too bright, or both. Both is always an option. I've been lucky...

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...

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...
