Video: 00:03:08 Henk Hoekstra, professor of observational cosmology at Leiden University, the Netherlands, shares his professional trajectory linked to weak gravitational lensing, a technique used by ESA’s Euclid mission.
Henk explains how Euclid will reveal the dark side of the Universe. He uses enlightening examples involving a swimming pool and other terrestrial objects. Listen to Henk Hoekstra to understand how Euclid can make the invisible visible.

ESA’s first human spaceflight mission lifted off 40 years ago today. Accompanied by the first ESA astronaut, Ulf Merbold, the Spacelab module took flight inside the Space Shuttle’s cargo bay, turning NASA’s ‘space truck’ into a mini-space station for scientific research. Europe continues to be highly active in the crewed module business to this day.

NASA to Showcase Earth Science Data at COP28
This illustration shows the international Surface Water and Ocean Topography (SWOT) satellite in orbit over Earth. SWOT’s main instrument, KaRIn, helps survey the water on more than 90% of Earth’s surface. Credit: NASA/JPL-Caltech. NASA/JPL-Caltech With 26 Earth-observing satellite missions, as well as instruments flying on planes and the space station, NASA has a global vantage point for studying our planet’s oceans, land, ice, and atmosphere and deciphering how changes in one drive change in others.
The agency will share that knowledge and data at the 28th U.N. Climate Change Conference of the Parties (COP28), which brings international parties together to accelerate action toward the goals of the Paris Agreement and the U.N. Framework Convention on Climate Change. COP28 will be held at the Expo City in Dubai, United Arab Emirates from Thursday, Nov. 30 to Tuesday, Dec. 12.
All U.S. events at COP28 are open to the local press and will be live-streamed on the U.S. Center at COP28 website and the U.S. Center YouTube channel.
NASA takes a full-picture approach to understanding all areas of our home planet using our vast satellite fleet and the data collected from their observations. The agency’s data is open-source and available for the public and scientists to study. NASA is showcasing the data at COP28 to share the different ways it can be used globally. The agency’s complete collection of Earth data can be found here.
The scientific research and understanding developed from NASA’s Earth observations are made into predictive models. Those models can be used to develop applications and actionable science to inform individuals including civic leaders and planners, resource managers, emergency managers, and communities looking to mitigate and adapt to climate change.
These satellites and models are augmented by the observations made from the International Space Station. The inclined, low Earth orbit from the station provides variable views and lighting over more than 90 percent of the inhabited surface of the Earth, a useful complement to sensor systems on satellites in higher-altitude polar orbits.
Closer to the surface, NASA’s aviation research is focused on advancing technologies for more efficient airplane flight, including hybrid-electric propulsion, advanced materials, artificial intelligence, and machine learning. Technological advances in these areas have the potential to reduce human impacts on climate and air quality.
Hyperwall
At the U.S. Center at COP28, in-person visitors can see the NASA Hyperwall where NASA scientists will provide live presentations showing how the agency’s work supports the Biden-Harris Administration’s agenda to encourage a governmentwide approach to climate change. During the hyperwall talks, NASA leaders, scientists and interagency partners will discuss the agency’s end-to-end research about our planet. This includes designing new instruments, satellites, and systems to collect and freely distribute the most complete and precise data possible about Earth’s land, ocean, and atmospheric system. A full schedule of NASA’s hyperwall talks is available.

Record-breaking NASA astronaut Frank Rubio provides the first Spanish-language video tour of humanity’s home in space – the International Space Station.
Rubio welcomes the public aboard the microgravity science laboratory in a behind-the-scenes look at living and working in space recorded during his 371-day mission aboard the space station, the longest single spaceflight in history by an American.
The station tour is available to watch on the agency’s NASA+ streaming platform, NASA app, NASA Television, YouTube, and the agency’s website.
Continuously inhabited for more than 23 years, the space station is a scientific platform where crew members conduct experiments across multiple disciplines of research, including Earth and space science, biology, human physiology, physical sciences, and technology demonstrations that could not be performed on Earth.
The crew living aboard the station are the hands of thousands of researchers on the ground conducting more than 3,300 experiments in microgravity. During his record-breaking mission, Rubio spent many hours contributing to scientific activities aboard the orbiting laboratory, conducting everything from human health studies to plant research.
Rubio returned to Earth in September, having completed approximately 5,936 orbits of the Earth and a journey of more than 157 million miles during his first spaceflight, roughly the equivalent of 328 trips to the Moon and back.

Video: 00:07:54 Focus on Euclid with Jean-Charles Cuillandre: “What we see in the first Euclid images is a promise of what will come in the future.”
Jean-Charles Cuillandre, astronomer at CEA Paris-Saclay, explains that he was “blown away” when he saw the first full-colour images captured by ESA’s recently launched Euclid space telescope.
Being a specialist of wide-field imaging, Jean-Charles was not only involved in the programme committee that selected the celestial targets for the ESA Euclid’s ‘Early Release Observations’, but he was also in charge of processing the data both for their scientific and their outreach value.
Jean-Charles expected the resulting images to look extremely crispy since they are taken by instruments outside of the Earth’s disturbing atmosphere, but even he was not prepared for the astonishing results. The combination of the field-of-view (the area of sky covered with a single shot of the telescope), and the resolution (the number of pixels in the instruments) are unique for Euclid.
The first five released images therefore show the scientific potential of the Euclid space mission. The Euclid Consortium is responsible to fulfill this promise. More than 2000 scientists from 300 institutes in 13 European countries, the US, Canada and Japan, will try to decipher the dark Universe through the analysis of Euclid’s scientific data.
In this interview, Jean-Charles Cuillandre shares with us his view of Euclid and the elusive dark matter and dark energy. He specifically describes the apparent astronomical objects and reveals the hidden information behind their beautiful appearance.
Be ready to be “blown away”.
