Our closest star, the Sun, is constantly emitting hot gas in all directions as its upper atmosphere, the corona, expands. This is known as the Solar Wind, also carrying with it an embedded magnetic field, the Interplanetary Magnetic Field (IMF). The IMF originates at the Sun and forms an enormous spiral throughout the solar system as the solar wind escapes radially, while the magnetic field-line ...[Read More]
Are you a student, or have obtained a MSc or PhD degree within the past 7 years? If yes, you are an Early Career Scientist! In the EGU we take great care of the young scientists, and offer a wide range of opportunities, mostly associated with the General Assembly. My name is Jone Peter Reistad and I am the Early Career Scientist (ECS) representative in the Solar-Terrestrial division. My role is to ...[Read More]
In this month’s (first ever for our blog) Life of a Scientist interview, we are very happy to talk to Dr Miho Janvier, a Researcher at the Institut d’Astrophysique Spatiale in Orsay (France), whose work has shed some light on the understanding of solar eruptions and coronal mass ejections (or solar storms) from their birth in the Sun’s corona to their evolution in interplanetary space ...[Read More]
The next solar eclipse is upon us. On August 21 the moon will pass between the Sun and an observer’s point of view in America and block out daylight, creating an eerie gloom in the sky. The transit of the moon between the Earth and Sun occurs about every 18 months, but for your particular city it can take several hundreds of years before a new eclipse occurs. The figure below shows the paths of al ...[Read More]
by Hugh S Hudson (U. of Glasgow and UC Berkeley) Normally solar eclipses give an observer only a fleeting moment (minutes at most) to enjoy the solar corona. We aim to amplify that considerably in the August 21 eclipse across North America. The plan is simple: Megamovie will capture everybody’s images, especially those from a group of 1,000 photographc volunteers, and compile them into an op ...[Read More]
Welcome to the ST division blog! The Solar-Terrestrial (ST) Division of European Geosciences Union (EGU) is starting its own blog! The blog is an initiative by a group of enthusiasts who met during the EGU’s General Assembly in April 2017. We are thrilled to set up this blog that will keep our readers informed about a range of topics relevant to the science of the division. The influence of the Su ...[Read More]
