Parkinson’s disease affects more than 5 million people on Earth. Research on the International Space Station could provide insight into this chronic neurodegenerative disease and help scientists find ways to treat and prevent it. In this video, NASA astronaut Serena Auñon-Chancellor narrates as European Space Agency (ESA) astronaut Alexander Gerst uses a microscope to examine and photograph the LRRK2 crystals.

The special Euclid space telescope from ESA is almost ready to go into space. It arrived in Florida on April 30th, and now it's being put together with the big SpaceX Falcon 9 rocket that will take it up there. The team at ESA's European Space Operations Centre in Germany is getting ready for the most important part of their work. They practiced what to do when getting ready for launch, like if someone on the team gets sick or if something strange happens, like a computer mouse getting stuck. Euclid is ESA's special telescope made to study the dark Universe. It's going to make a really big and accurate map of the Universe in 3D, like a space map. It will look at how the Universe got bigger and how things are spread out in space and time. This will help us understand more about how gravity works, and about the strange dark energy and dark matter. Euclid is planned to take off on a SpaceX Falcon 9 rocket from Florida on July 1st, 2023, at 11:11 in the morning local time. If it doesn't work that day, they have another plan for July 2nd, 2023. It's an exciting time, and everyone is waiting to see what Euclid will find out about the Universe.

Embarking on a journey into the enigmatic realms of the cosmos, the European Space Agency's (ESA) Euclid mission aims to illuminate the concealed aspects of the Universe. Drawing insights from the intricate dance of galaxies as they rotate, intermingle, and expand, astronomers have posited the existence of two elusive entities that hold sway over the cosmic tapestry: dark matter and dark energy. These enigmatic forces exert their influence indirectly, shrouding themselves in secrecy, their presence only inferred from the cosmic ballet they choreograph. To unravel the mysteries of dark matter and dark energy, a mission of unprecedented precision is required, one that delves deep into the annals of galactic history, scrutinizing their effects on galaxies, galaxy clusters, and the very fabric of spacetime itself. Enter Euclid, ESA's flagship undertaking poised to decode the hidden language of the Universe. Euclid's groundbreaking mission is set to chart the Universe in three dimensions, with the fourth dimension intricately interwoven—time itself. Galaxies positioned in the distant reaches of the cosmos bear witness to epochs past, their light traversing immense distances before gracing our senses. Through meticulous observations of countless galaxies, extending a staggering 10 billion light-years away, Euclid will meticulously trace the cosmic choreography of galaxies, capturing their positions, velocities, and transformations across the eons. Moreover, Euclid's unparalleled optical prowess will unveil the subtle distortions that bespeak the secrets of galaxies' appearances. From this treasure trove of newfound knowledge, astronomers stand poised to deduce the enigmatic properties of dark energy and dark matter with an unprecedented degree of accuracy. These revelations promise to illuminate the elusive nature of these cosmic constituents, refining our comprehension of how gravity governs the vast expanses of the Universe. Euclid's journey into the cosmic unknown is poised to revolutionize our understanding of the forces that shape the celestial expanse, unveiling the hidden threads that bind the Universe together.

Venture into the captivating realm of space exploration as we unveil the remarkable journey of the OSIRIS-REx mission, entwined with the enigmatic asteroid 101955 Bennu. A celestial giant, towering akin to a skyscraper, Bennu stands as one of Earth's closest planetary companions. This narrated video chronicles the intricate tale of OSIRIS-REx, an emissary from humanity, and its immersive embrace of Bennu's mysteries since its arrival on December 3, 2018. From the moment OSIRIS-REx touched Bennu's surface, an intricate tapestry of observations began to unfold, interweaving science and curiosity. As the mission's meticulous dance with Bennu flourished, it painted a vivid tableau of cosmic revelations against the backdrop of space. With a touch of melancholic farewell, OSIRIS-REx bids adieu to its cherished companion on May 10, 2021, embarking on a triumphant voyage back to Earth. Nestled within its protective confines are over 60 grams of precious samples, meticulously gathered from the heart of Bennu itself. Experience the complete trajectory of OSIRIS-REx during its transformative sojourn at Bennu, a testament to human ingenuity and the insatiable thirst for exploration.
