A close-up journey to the Sun: The Parker Solar Probe Mission

Almost two months ago, in August 12, 2018 Parker Solar Probe (PSP) launched by NASA on a Delta IV Heavy rocket from Cape Canaveral, Florida. This is a long-awaited mission from the Heliospheric community. The first to explore the Sun within distances of ~0.167 AU (or 25 million kilometers) at its perihelia. Its ancestors were the successful Helios -A and -B spacecraft, a pair of probes launched in ...[Read More]

Meeting Plate Tectonics

The sixties brought us many moving moments: Woodstock, the civil rights movement, the moon landing… and the establishment of the plate tectonic theory. It is during the turbulent late sixties that scientists published groundbreaking manuscripts proving that pieces of the Earth’s outer layer are in a constant state of motion. In Late 1967 to mid-1968, Dan McKenzie and Robert L. Parker, Jason ...[Read More]

Volcanic eruptions: Sometimes natural spectacles, but other times disasters

October 22, 2018

In April 2018, an eruption of the Kilauea volcano in Hawaii started. The activity continued for months, with impressive lava flows that cut roads and even covered houses and entire neighbourhoods (Figure 1), forcing the evacuation of thousands of people. Fortunately, it did not take any life. Some weeks later, on June 3rd,  Fuego volcano, in Guatemala, shocked the international community with a sh ...[Read More]

Image of the Week – On thin [Arctic sea] ice

Perhaps the most enduring and important signal of a warming climate has been that the minimum Arctic sea ice extent, occurring each year in September, has declined precipitously. Over the last 40 years, most of the Arctic sea ice has thus been transformed to first-year ice that freezes in the winter and melts in the summer.            Concern about sea ice extent and area is valid: since sea ice i ...[Read More]

Imaggeo on Mondays: Life between the arid mountains of Gansu, China

Even within Earth’s more arid environments, you can find life! This featured photo was taken near the Lanzhou Zhongchuan Airport, about 50 km away from Lanzhou city, the capital of Gansu province in Western China. The area lies in a region between the Qinghai-Tibet Plateau and the Loess Plateau, with an elevation ranging from 1,500 m to 2,200 m. The landscape is dominated by a network of ridges an ...[Read More]

Oceans on Mars: the geodynamic record

Apart from our own planet Earth, there are a lot of Peculiar Planets out there! In this series we take a look at a planetary body or system worthy of our geodynamic attention, and this week we are back to our own solar system, more precisely to our neighbour Mars. In this post, Robert Citron, PhD student at the University of California, Berkeley, writes about the links between oceans, shorelines, ...[Read More]
