From Destruction to Creation: Understanding Meteorite Impact Craters

Ever since the planets first formed, they have been bombarded with space rocks. Asteroid and cometary collisions are so forceful that planetary surfaces fracture and melt beneath them, leaving behind huge craters. These impact events have played an important role in our planet’s history, by shaping the geological landscape, producing valuable minerals, and affecting the …

Early magma oceans of Earth detected in 3.7 billion-year-old Greenland rocks

Earth hasn’t always been a blue and green oasis of life in an otherwise inhospitable solar system. During our planet’s first 50 million years, around 4.5 billion years ago, its surface was a hellscape of magma oceans, bubbling and belching with heat from Earth’s interior.

Scale and composition of Earth’s surface

In collaboration with Dr. Christine Houser (@seismodoc), a specially appointed assistant Professor of solid Earth geophysics at the Earth-Life Science Institute in Japan, NASA Goddard Planetary Scientist Dr. James O’Donoghue (@physicsJ) created another amazing animation titled “Scale and Composition of Earth’s surface: Major constituents of the crust, water, and atmosphere” and published on his YouTube …

What are lost continents, and why are we discovering so many?

For most people, continents are Earth’s seven main large landmasses. But geoscientists have a different take on this. They look at the type of rock a feature is made of, rather than how much of its surface is above sea level. In the past few years, we’ve seen an increase in the discovery of lost …

Amazing footage shows a boat speeding away as the Stromboli volcano erupts

On August 28, Stromboli volcano in Italy woke up a second time this summer. Tourists decided to ride a boat near the erupting volcano – but the journey turned out to be “fun”: they had to escape from the wave of pyroclastic flow. The eruption did not lead to casualties and destruction, but the tourists …

What kills you when a volcano erupts? It’s not what you think

The blockbuster movie Jurassic World: Fallen Kingdom (2018) involves more than just dinosaurs wreaking havoc. Humans are sent in to rescue some prehistoric critters on the volcanic island of Isla Nublar, and chaos soon begins. The volcano erupts, and everyone runs away as a roiling cloud called a pyroclastic flow approaches. At one point the …

The exact moment of Stromboli Eruption filmed in a sailboat

Mount Stromboli, one of the three active volcanoes in Italy (others being Mount Etna on Sicily – continuous activity, and Mount Vesuvius, near Naples – last erupted in 1944), has been in almost continuous eruption for the past 2,000 years. The last eruption took place on 3 July 2019. The exact moment of the event …

Earth’s oldest rock has been found… on the Moon!

According to research published in the journal Earth and Planetary Science Letters, Earth’s oldest rock (which is 4.1 billion years old) has been found in an Apollo 14 sample from the Moon. If confirmed, it’s an amazing discovery.

Mount Etna is sliding into the sea

Mount Etna, Europe’s most active volcano (also one of the most active volcanoes in the world) is sliding into the Ionian Sea at rates of centimeters per year. If part of it falls into the sea, it could create horrible mega-tsunamis that would devastate the eastern Mediterranean shores.

Structure of Earth

The universe is shrouded in mystery, and part of this mystery involves our own little planet. Although there has been countless research, the scientists and experts have only been able to barely scratch the surface (both figuratively and literally) in case of planet earth. However, the studies in Seismology have allowed us to gather sufficient …
