In this week’s Imaggeo on Mondays, Bjørn Gitle Hauge – from Østfold University College – opens our eyes to the astounding aurora borealis, and the unusual phenomena seen in Norway’s night sky… Hessdalen is a former mining district in the middle of Norway with huge ores of copper and mineshafts up to a kilometre deep. The climate here is sub-Arctic, with temperatures reaching as low as -50 de ...[Read More]

Thermal imaging of volcanic eruption plumes
Thermal imaging using infra-red cameras is now a widely used tool in the monitoring and analysis of volcanic explosions, and this pair of time-series snapshots of two short-lived ‘Vulcanian‘ explosions at Volcán de Colima, Mexico, shows one example of why. In each panel, times (in seconds) are times since the start of the explosion sequence; and the temperature scales (vertical colour ...[Read More]

Capturing Cassini – 10 years of Saturnian science on camera
This year marks the 10th anniversary of the Cassini-Huygens mission to study Saturn and its moons. But what’s 10 years to us is only a fraction of the Saturnian calendar – in the decade we’ve been studying Saturn up close, the planet has been through only a third of its annual cycle. In that short time though, scientists have made a multitude of amazing and surprising discoveries about the system ...[Read More]

Last dinosaur of its kind found in the land that time forgot
In terms of iconic dinosaurs, the gargantuan sauropods are certainly up there. Along with the mostly meat eating-theropods, and herbivorous and often armoured ornithischians, they form one of the three major groups, or clades, of dinosaurs, and were the biggest animals to ever walk this Earth. The end of the Jurassic period, some 145 million years ago, was a pretty important time for sauropods. Th ...[Read More]

Social Media and the Seven Twitter Accounts
“Postpublication peer review on social media is like the mosh pit at a punk rock conference. It’s fast, uncoordinated, a lot less subtle, more in your face, and involves a few more risks.’ Peer review is the cornerstone of scientific legitimacy – it is the process where research is analysed by your professional peers. Traditionally, this has been conducted before the public ...[Read More]

Imaggeo on Mondays: Layers of leg-like sandstone
John Clemens, a researcher from Stellenbosch University and one of the winners in the EGU Photo Contest 2014, opens our eyes to erosional processes in the Grand Canyon in this week’s Imaggeo on Mondays… The photo below was taken late in the afternoon while doing some geological tourism at the Grand Canyon in Arizona, USA. The light at this time of day is ideal for such locations as it has a ...[Read More]

Another clue to the origins of dinosaurs
Often the early evolution and radiation of the first dinosaurs is an overlooked part of their tale, in favour of the more dramatic but arguably no less important tales of their later radiations and extinctions. It is actually a fairly poorly understood part of their evolution too, with the timing, and actual mechanism that drove them to become the most successful land group ever still a bit of a m ...[Read More]
