Shouldn't the cascades of extinction and rapid planetary warming register in our literature?
As a planetary scientist, I don't know what else to call Pluto: It's big and round and thousands of miles wide.
It now appears that essentially every star has a planetary system. In the very beginning, we thought at best half.
I've been on 26 space missions; they range from suborbital to orbital to shuttle experiments to planetary missions.
I tell public audiences, don't go to a podiatrist for brain surgery; don't go to an astronomer for planetary science.
Planetary missions are great, but they're usually only brief snapshots of those planets and also really very close-up.
You stop planetary exploration, those people who do that extraordinary work are going to have to go do something else.
No government in the world today has explicitly assigned the responsibility for planetary protection to any of its agencies.
If you go to planetary science meetings and hear technical talks on Pluto, you will hear experts calling it a planet every day.
Our world faces a true planetary emergency. I know the phrase sounds shrill, and I know it's a challenge to the moral imagination.
The big lesson of planetary science is when you do a first reconnaissance of a new kind of object, you should expect the unexpected.
We were very surprised to find out that Pluto is still geologically alive. It has upended our ideas of how planetary geophysics works.
Earth's biosphere gave birth to humans and our thoughts, which are now reshaping its planetary cycles. A planet with brains? Fancy that.
As a planetary system, Saturn holds the greatest promise for answering questions that have a far broader scientific reach than Saturn itself.
To say that what a planet is doesn't matter would be to imply that a planetary scientist couldn't explain to someone what the field is about.
As our sensitivity improves, we are finally seeing planets with longer orbital periods, planetary systems that look more like our solar system.
Most of the solar system resides beyond the orbits of the asteroids. There is more to learn there about general planetary processes than on Mars.
I'm an astrobiologist, and I come from a planetary science background, so in a very broad sense, I study the evolution of planetary environments.
I believe it is essential for our planetary future to develop tools that can change the consciousness which has created the crisis that we are in.
Neptune's unusual behavior is showing us that though we can make great models of planetary atmospheric circulation, there may be key pieces missing.
The Kuiper Belt is the largest mapped structure in our planetary system, three times as big as all the territory from the sun out to Neptune's orbit.
I'd love to go into space again if there were a mission to Mars. I'd also love to go to a completely different planetary system, out of our solar system.
I think that an advanced planetary civilization will modify their own planets to be more stable, to prevent asteroid impacts and dangerous climate fluctuations.
I do a lot of work with NASA and am involved in research projects studying planetary evolution, Earth-like planets, and potential conditions for life elsewhere.
Whether a star has planetary companions or not is a condition of its birth. Those with a larger initial allotment of metals have an advantage over those without.
Our planetary system is affected by a magnitude of force as powerful as any naturally occurring global catastrophe, but one caused solely by a single species: us.
I was in Los Angeles prepping my episode of 'Dollhouse' when the final 'Planetary' hit the stands in October. Yeah, it was surreal. One chapter closing, another opening.
It would be impossible in a few words to describe all that we've found with Cassini. No mission has ever gone as deep for as long on a planetary system as rich as Saturn's.
One of the first thoughts I had, when doing early exoplanet research, was that Earth and its many companions seemed very different from the planetary systems we were detecting.
Preventing global warming from becoming a planetary catastrophe may take something even more drastic than renewable energy, superefficient urban design, and global carbon taxes.
Photosynthetic organisms in the sea yield most of the oxygen in the atmosphere, take up and store vast amounts of carbon dioxide, shape planetary chemistry, and hold the planet steady.
You won't see me writing about particle physics, or even planetary geology, or chemistry. I practically failed chemistry, and if I had to write a book in any of those areas, I don't think it would go well.
As digital communications have multiplied, and NSA capabilities with them, the agency has shifted resources from surveillance of individual targets to the acquisition of communications on a planetary scale.
Why would you need to expand beyond the solar system if you already have access to all the information you need, and you've essentially insulated yourself against a planetary apocalypse? Maybe that's enough.
There is no fixed physical reality, no single perception of the world, just numerous ways of interpreting world views as dictated by one's nervous system and the specific environment of our planetary existence.
Ever since the environmental movement was sparked by photos of the whole Earth taken by astronauts onboard Apollo Lunar Modules, I've seen planetary exploration as an extension of a reverence and care for Earth.
Space exploration promised us alien life, lucrative planetary mining, and fabulous lunar colonies. News flash, ladies and gents: Space is nearly empty. It's a sterile vacuum, filled mostly with the junk we put up there.
In all religions, we hear of the Seven Planetary Genii: the Hindu tells of Seven Rishi, the Parsi of Seven Ameskaspentas, the Mohammedan of Seven Archangels, and our Christian religion has its Seven Spirits before the Throne.
New Horizons isn't just visiting Pluto; it's visiting this entire region. Whatever it finds, this will be a signal moment for planetary exploration - the capstone to our first reconnaissance of the planets of our solar system.
In any 'big science' enterprise, like planetary exploration, where you must work in big teams of similarly driven people, it is important also to know how to work alongside others even when they may be your fiercest competitors.
As you may know, I'm the co-founder and co-chairman of an asteroid company called Planetary Resources that is backed by a group of eight billionaires to implement the bold mission of extracting resources from near-Earth asteroids.
When we realize that human beings are entering the world constantly and that each being is stamped at the first complete breath with the planetary pattern then in the sky, everyone must necessarily be different from everybody else.
Many of the most science-fictional tools to fight climate change are untested, are almost impossible to truly test at planetary scale - we only have one planet after all. We're better off cutting our emissions so we don't need them.
It is wonderful to contemplate how the planetary forces balance each other so perfectly that universal equilibrium is maintained despite the disturbances of the 1,500 millions which inhabit the Earth alone, not to speak of other spheres.
You cannot study other planets without referring to Earth and without applying the techniques and the insights of Earth science. And you cannot really do a good job understanding the Earth without the insights from planetary exploration.
