As this winter’s polar vortex currently sends extreme icy blasts of Arctic weather to some parts of the northern hemisphere such as the northeast of the US, scientists are using wind information from ESA’s Aeolus satellite to shed more light on this complex phenomenon.

A satellite-based dataset generated by KAUST researchers has revealed the dynamics of dust storm formation and movements over the last decade in the Arabian Peninsula. Analysis of this long-term dataset reveals the connection between the occurrence of extreme dust events and regional atmospheric conditions, a finding that could help improve weather forecasting and air-quality models. Dust

In the event of a forest fire, flash flooding or a landslide, how can firefighters and rescue workers get to the disaster site as quickly as possible? What measures need to be taken? What lessons can be learned from past disasters? The HEIMDALL project provides answers via a digital platform that collects all of this information. At the virtual final presentation of the project, the benefi

Elon Musk's SpaceX plans to launch two Starlink communications satellite cluster missions from Florida in one day Thursday - the first time in history for such a feat by a launch company. The first launch is planned at 1:19 a.m. EST from Complex 40 at Cape Canaveral Space Force Station, followed by another just over four hours later at 5:36 a.m. EST from Complex 39A at Kennedy Space Ce

Tensions between the US and Iran have been especially high ever since Trump in 2018 withdrew from the 2015 Iran nuclear deal, also known as the Joint Comprehensive Plan of Action (JCPOA), and reinstated harsh sanctions against Iran. The JCPOA stipulated that Iran would receive waivers from sanctions if it agreed to limit its nuclear programme. Iran on Monday shared a video of its new domes

Washington (AFP) Feb 2, 2021
The United States on Tuesday voiced concern about Iran's launch of a satellite-carrying rocket, saying the test could boost missile work at a moment when the two nations are inching back to diplomacy. "The United States remains concerned with Iran's efforts to development space launch vehicles (SLVs), given these programs' ability to advance Iran's ballistic missile development," a State Dep

It started with a movie. Supernovas filled the screen and exploded with galactic color. The voice of Neil DeGrasse Tyson narrated the beginning of the universe. At only 14 years old, Alana Sanchez was hooked. Prior to high school, Sanchez was primarily interested in visual arts and movies. She taught herself animation and aspired to work in the creative realm. However, her dreams quickly t

A new study has found that electrons can reach ultra-relativistic energies for very special conditions in the magnetosphere when space is devoid of plasma. Recent measurements from NASA's Van Allen Probes spacecraft showed that electrons can reach ultra-relativistic energies flying at almost the speed of light. Hayley Allison, Yuri Shprits and collaborators from the German Research Centre

A team of researchers led by SETI Institute Senior Research Scientist Janice Bishop, a member of the SETI Institute NASA Astrobiology Institute (NAI) team, has come up with a theory about what is causing landslides on the surface of Mars. Previous ideas suggested that liquid debris flows or dry granular flows caused this movement. Neither model can completely account for the seasonal marti
