Here’s a familiar question: How’s the weather? We’re familiar with the weather on Earth and telescopes and missions are watching the weather on other planets in the Solar System. But for the first time in history, astronomers can now answer that question for exoplanets, located light-years away from us.
Most of the exoplanets we’ve found are around stars, where they belong. But a few have been found free-floating in interstellar space. The evidence is growing that there are a lot of them out there, maybe even more than planets with stars. How do they form and how can we learn more about them?

Our galaxy series continues, on to spiral galaxies. In fact, you’re living in one right now, but telescopes show us the various shapes and sizes these galaxies come in. Thanks to JWST, we’re learning how these spirals got big, early on in the Universe.

How old is that star? That planet? That nebula? Figuring out the ages of astronomical objects is surprisingly challenging. Fortunately, astronomers have developed a series of techniques they can use to work out the ages of stuff.
Last week, we learned about the death of Peter Higgs, a physicist and discoverer of the particle that bears his name. The Large Hadron Collider was built to find and describe the particle. Today, we’ll look back at the life of Peter Higgs and his particle.
How to watch a solar eclipse and do some science!
Several of the planets and moons in the Solar System are in orbital resonance, orbiting in a geometric lockstep. And not just the Solar System, astronomers have found the same resonances in other star systems.
Last week was one of the most exciting meetings we’ve seen from the Lunar and Planetary Science Conference, with hundreds of announcements and discoveries from various missions. One theme kept coming up, the Solar System is more volcanically active than we thought. Today, we’ll explore volcanism on other worlds.
You’ve probably heard that the best kind of science is peer-reviewed research published in a prestigious journal. But peer review has problems of its own. We’ll talk about that today.
NASA works on many missions using tried and true technology, but they also invest in creative ideas that could drive the future of space exploration. It’s called NASA’s Innovative Advanced Concepts or NIAC.
In the olden days, NASA developed its missions using a variety of in-house engineers and external suppliers. As more commercial companies are targeting the Moon, NASA is working with partners to deliver its payloads to the lunar surface. Today let’s talk about NASA’s Commercial Lunar Payload Program.

Last week we talked about sample return missions from the Moon and Mars, but scientists have retrieved samples from other objects in the Solar System, including comets and asteroids. What does it take to return a piece of rock from space, and what have we learned so far?
We’ve sent robots to other worlds, but the amount of science we can deploy to another planet can’t compare with the vast science labs we have on Earth. That’s why more and more missions are for a sample return, bringing pieces of alien worlds back to Earth, where we study them with proper equipment.
We’re so familiar with NASA’s exploration efforts in space, but you might be surprised to learn that China launches almost as many rockets as the US. They’ve got their own space exploration program that could soon bring humans to the surface of the Moon. Let’s give a brief overview of China’s space exploration plans.
Wherever we find liquid water on Earth, we find life, so it makes sense to search for water across the Universe, and hopefully we can find evidence of life. But what about worlds which are completely covered in water, oceans hundreds of kilometers deep. Can there be too much water?
NASA’s Juno spacecraft has completed dozens of flybys of Jupiter, seeing the planet from many angles and delivering some of the most beautiful images we’ve ever seen of the Jovian world. Now it’s focusing in on Io, sending home images of the tiny volcanic world from just 1,500 km away. And the best is yet to come.

Last week we looked back at some of the ideas that science has changed its mind about. This week we look forward, into the future, at some of the big ideas that astronomers are making progress in. What space science are we looking forward to?
Astronomers talk about all the amazing discoveries they’re making but sometimes, it turns out, they were wrong. After decades and centuries of discoveries, how have they changed their minds?
Just a warning, the holidays are rapidly approaching. It’s time, once again, to think about what to buy all the space nerds on your lists. Here’s what we like.
How the time flies. It’s been over a year since JWST went operational, with other missions joining the fun. What new insights have we gained about the Universe thanks to these powerful new tools?
Finally, we reach the end of our tour through the missions in the Solar System. Out beyond Mars, to Jupiter, the Kuiper Belt and Beyond.
