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.

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”.

NASA Administrator Bill Nelson gives remarks after Indian Ambassador to the United States Taranjit Sandhu signed the Artemis Accords, Wednesday, June 21, 2023, at the Willard InterContinental Hotel in Washington.NASA/Bill Ingalls NASA Administrator Bill Nelson will travel to India and the United Arab Emirates (UAE) for a series of meetings beginning Monday, Nov. 27, with key government officials.
Nelson also will meet with space officials in both countries to deepen bilateral cooperation across a broad range of innovation and research-related areas, especially in human exploration and Earth science.
The visit to India fulfills a commitment through the United States and India initiative on Critical and Emerging Technology spearheaded by President Joe Biden. Nelson will visit several locations in India, including the Bengaluru-based facilities where the NISAR spacecraft, a joint Earth-observing mission between NASA and the Indian Space Research Organization (ISRO), is undergoing testing and integration for launch in 2024. NISAR is short for NASA ISRO Synthetic Aperture Radar.
As the first satellite mission between NASA and ISRO, NISAR is a revolutionary Earth-observing instrument, the first in the Earth System Observatory, that will measure Earth’s changing ecosystems, dynamic surfaces, and ice masses providing information about biomass, natural hazards, sea level rise, and groundwater, key information to guide efforts related to climate change, hazard mitigation, agriculture, and more.
While in the UAE, Nelson will participate in the 2023 United Nations Climate Change Conference, highlighting NASA’s role as a global leader in providing decisionmakers with critical Earth-science data. It will be the first time a NASA administrator will have attended the conference.
Students in each country also will have the opportunity to meet with Nelson to discuss science, technology, engineering, and mathematics (STEM) education and their roles as members of the Artemis Generation.
