Hello again, Earthlings!

Let's talk about what in the world are pyroclastics!

Pyro- meaning fire, and clastics- meaning rock chunks, are referring to globs of rock spewed from volcanoes! Pyroclastics can come in a variety of shapes and sizes, but finding them can tell us many secrets about the surrounding volcanoes- mainly- how destructive they can be!

Pyroclastics on Mars was once a tricky thing to decipher from low resolution images, but the recent HiRISE camera has given us many images to look for such pyroclastic grounds. 

Why look for pyroclastics? Because finding how much and how concentrated in an area could give us insight into the past ancient dynamics of Mars' large volcanoes!

So far, recent research led by Dr. Broz of the Institute of Geophysics, The Academy of Sciences of the Czech Republic, has found that pyroclastic mounds are relatively recent and from majorly explosive volcanic sources!

Thank you for reading and come back next week for a look at why we should go back to the Moon!
