Bluring the lines – an active asteroid #NASASDawn #Ceres

Asteroids are the left overs, the non-planets, the bits that never quite formed that missing planet between Mars and Jupiter. Because of this, they are small, cold, dead. Except when they is an exception to the rule. And Ceres is that exception

On the same day Pluto was demoted to Dwarf Planets, Ceres got promoted *to* Dwarf Planet. It is clearly and asteroid belt object, but it is much bigger than the other asteroids. So big that it was once alive and (barely) active. In 2015 the NASA Dawn spacecraft imaged a volcano on Ceres. The mystery was that it was the only one on the whole body. As Michael Sori of the Lunar and Planetary Laboratory at the University of Arizona, lead author of a new paper accepted for publication in Geophysical Research Letters states,“Imagine if there was just one volcano on all of Earth. That would be puzzling.”

In this new research Dr Sori posits Viscous relaxation as the solution to this conumdrum. More mysteries, more answers, more knowledge gained about our solar system.

  1. I find it remarkable how fast our technology is changing that makes it able for scientists to explore other theories. With this new theory of being able to find out how these ice volcanoes come and go, imagine the possibilities of what you can find on other planets. I’m excited to see what new findings or theories are discovered on Ceres and other dwarf or non dwarf planets.

  2. Finding out Pluto was no longer a planet was genuinely disappointing when i was younger, because i had grown up knowing it as a planet. Now that it is considered a dwarf planet it is so fascinating to see that there are several other dwarf planets and they seem just as important. To see that one even has a volcano makes it more interesting.

  3. I remember learning the acronym My Very Eager Mother Just Served Us Nine Pizzas, this being said I learned that Pluto is a planet. Very spontaneously teachers told me Pluto is not a planet. What in science progressed to make this decision? What decides something is a “Dwarf” planet?

  4. It is amazing to find out that asteroids are just the left overs of what could have been another planet. It is also amazing to know that Ceres was once an active planet, it makes me wonder what interesting facts scientists could have found if it was still active.

  5. It’s really amazing how much we keep learning about our universe as time passes. What we once thought was a simple, dead asteroid is actually a dwarf planet that once was active with a volcano. I can’t wait to hear what astronomers discover as to the reason why there’s only one volcano in all of Ceres, I know it’ll truly be eye-opening.

  6. That is amazing I didn’t know that’s what an active asteroid looks like. I had no idea volcanoes could form on dwarf planets. I wonder how soon it will be before a volcano forms on Pluto.

  7. I didn’t even know that there was another planet named a dwarf planet at the same time as Pluto. It just amazes how much we are discovering, especially on a unique asteroid. I didn’t know there was such a thing as an ice volcano, how exciting!

  8. It’s insane to think that what once was considered an asteroid in our solar system is now looked at as a dwarf planet. My question is what requirements or qualifications does it take to change from an asteroid to a dwarf planet? Why wasn’t it a dwarf planet to begin with?

  9. This article was very educational, I had no idea that ice volcanoes even existed! Very interesting to find out that Ceres only has one moon, and that it was made a dwarf planet the same day Pluto was, and also that it’s the closest dwarf planet to the Sun.

  10. It’s crazy how we are always changing our perceptions of things as soon as a new discovery is made. It’s also crazy to think that something we originally thought was an asteroid, could have been a planet! I’m still interested in finding out why there is only one volcano…
