Here's an animated gif showing 3 satellite images from #ESA#Sentinel2, 31st March, 9th and 13th April. At the start of April a big iceberg has calves off the front. The animation also shows the ice moving forward.
The start of the mélange zone in front of Melville Glacier, massive and fresh icebergs formed an ice wall. Large calving event this week, slightly unusual so early in the year and with so much fast ice, unfortunately we missed recording it but our instruments will get the next one. Greenland loses around half of it's ice by calving so it's an important process to understand.
This glacier is clearly very dynamic.
It's an incredible field site, the glacier is continuously pushing and heaving and you can hear it while you're there. Lots of seals around on the sea ice too and many polar fox tracks...
Some long days and no internet so posting a few late pictures now with some fieldwork updates. Satellite image from ESA's Sentinel 2 mission, processed on snapplanet
Looking deep into space and time, two teams using the NASA/ESA/CSA James Webb Space Telescope have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old Universe was only about 430 million years old.
"It’s important because large system integrators – the big companies that lead satellite projects – are going to need systems that are fully compliant with debris mitigation regulations. And the need is becoming urgent as more and more satellites are placed in space.” #ESA#Satellites#D4D#SatelliteConstellations
For the first time, potential signs of the rainbow-like ‘glory effect’ have been detected on a planet outside our Solar System. Glory are colourful concentric rings of light that occur only under peculiar conditions.
Data from ESA’s sensitive Characterising ExOplanet Satellite, Cheops, along with several other ESA and NASA missions, suggest this delicate phenomenon is beaming straight at Earth from the hellish atmosphere of ultra-hot gas giant WASP-76b, 637 light-years away.
Extreme weather, including flooding, is becoming more frequent as climate change takes its toll on the planet. One of the many regions to be hit by floods in recent years is the south of France, with heavy rainfalls caused in part by humidity above the Mediterranean Sea.
The Robusta-3A satellite, launching on Ariane 6’s first mission, is set to fly 580 km over our planet to help quantify the accumulation of water vapour over the Mediterranean Sea and improve the forecast of severe rain leading to flooding.
An "eclipse also acts as a laboratory for researching what happens to weather when the Moon’s shadow passes over. The shadow makes air temperatures drop and can cause clouds to evolve in different ways. Data from GOES, Sentinel-3 and other satellites are now being used to explore these effects."
Wer mich übrigend im Raum #Karlsruhe über das #ESA#Euclid-Weltraumteleskop sprechen hören möchte, kann das am kommenden Montag, 8.4., um 20 Uhr im #Naturkundemuseum Karlsruhe erleben.
