Using satellite data to expand understanding of river flow dynamics
Tuesday, 01 October 2024 17:45
Since 1953, an equation known as at-a-station hydraulic geometry (AHG) has been used to explain the relationship between river width, depth, velocity, and river discharge - the volume of water flowing through a river channel. AHG plays a key role in hydraulic engineering, flood prediction, and navigation. However, traditional methods for studying AHG through field research offer limited sample s EchoStar plots direct-to-device satellite push after shedding Dish and debt

Dust sparked biggest phytoplankton bloom in decades

New research reveals that dust carried by the wind from southern Africa towards Madagascar triggered the largest phytoplankton bloom in two decades – and, unusually, this occurred at a time of year when such blooms are rarely seen.

Unveiling the hidden snow dunes shaping Antarctica's frozen landscape
Tuesday, 01 October 2024 06:00
Sand dunes are a familiar sight along beaches and in deserts. While we know how regular sand dunes are formed, much less is known about dunes made of snow. In a new study, scientists have analysed the vast snow dunes across Antarctica – reshaping our understanding of the continent's surface dynamics.
This research sheds light on the unexplored world of Antarctic snow dunes, offering a fresh perspective on the complex interactions between wind, snow and climate in one of Earth's harshest environments.

New mission to create total solar eclipses in space
Monday, 30 September 2024 15:52
A UK team of researchers including UCL's Professor Lucie Green are working on the launch of a spacecraft mission that will allow us to view the sun's atmosphere in more detail than ever before.
The proposed MESOM mission will enable researchers to study the conditions that create solar storms, leading to improvements in forecasts of space weather on Earth.
The MESOM spacecraft will fly on a peculiar trajectory enabled by the gravitational attraction of the Earth, the sun and the moon, and will use the shadow of the moon to re-create a total solar eclipse in space once every lunar month lasting almost 50 minutes.
Total solar eclipses seen from Earth are much shorter and only last between 10 seconds and 7.5 minutes, with the annular solar eclipse in the Southern Hemisphere this Wednesday 2 October expected to last around seven minutes.
Creating a longer eclipse in space will enable the MESOM team to take high-quality images and measurements of the sun's corona, filling gaps in existing understanding of the physical processes taking place in the solar atmosphere that lead to space weather.
SpaceX docks at ISS to take Starliner astronauts home next year

The SpaceX crew that will ferry back in February two astronauts stranded on the International Space Station docked with the orbiting laboratory on Sunday, a live stream of the mission showed.
The Falcon 9 rocket took off at 1:17 pm (1717 GMT) from Cape Canaveral, Florida on Saturday, with the Crew-9 mission aboard a Dragon spacecraft making contact with the ISS at 5:30 pm Sunday.
