While it’s a powerful tool, seismology methods pose a challenge for gas planets. But because Saturn has a complex ring system, its vibrations can be measured indirectly. The process is known as Kronoseismology.
The Edge of Wetness
The history of our search for water on Mars is a bit convoluted, and like many discoveries in science it has happened in small steps rather than a revolutionary discovery.
Target Acquired
Having successfully flown past Pluto, New Horizons sets its target on an icy body in the Kuiper belt.
How Special is the Solar System?
It increasingly looks like our solar system might be the exception rather than the norm.
Crust of Mars
Mars had a continental crust similar to early Earth’s. That’s the finding of a new paper published in Nature Geoscience.
The Mountains of Pluto
There are mountains on Pluto, and that actually tells us quite a bit about the dwarf planet.
The Long Journey
For decades Pluto was simply a faint dot on a photographic plate. In less than a century we have turned a faint point of light into a beautiful reddish world.
Pluto Rising
New Horizons is closing in on Pluto, and that means we’re finally getting some detailed images of the small world. With the appearance of new surface features comes a new batch of questions.
The Snows of Mars
The most popular view of early Mars is that it was a warm and wet planet. But new climate models suggest young Mars might have been cold and icy.
