ESA is building its first space telescope to investigate how dark energy and dark matter control our universe. » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Countdown to Launch: http://bit.ly/CTLplaylist Thumbnail Credit: Thales Alenia Space and Airbus Defence and Space The universe is filled with planets, meteors, black holes, and galaxies—each with their own set of mysteries. But one of the best concealed aspects of deep space exists in what scientists describe as “the dark universe.” The dark universe is where dark energy and dark matter are hidden, interacting with the matter we can actually see. And because we can’t see this dark side directly, scientists know very little about dark energy and dark matter. It has taken decades to attempt to understand the dark side, but ESA’s space telescope mission, named Euclid, might just give us some answers. The Euclid mission could piece together the puzzle that surrounds dark energy and dark matter, essentially helping us understand how the universe works. ESA’s Euclid space telescope will not only map the geometry of the dark universe and provide it’s cosmic history, Euclid will also observe and analyze the shape and redshift of thousands of millions of galaxies spanning back 10 billion years. Ultimately, this will provide a large-scale 3D map that allows scientists to see how dark energy has played a significant role in the universe's expansion. Euclid will also be on the hunt for Baryonic Acoustic Oscillations or what ESA describes as “wiggle patterns” within galaxy clusters. These patterns provide a standard ruler method for measuring dark energy with the expansion rate of the universe. Find out more about dark matter, dark energy, and the Euclid mission on this episode of Countdown to Launch. #Euclid #Launch #ESA #Universe #Seeker #Elements #Science Countdown To Launch Season 1 Playlist - https://www.youtube.com/playlist?list=PL6uC-XGZC7X7unk5w-u8J4RR2EdCck0wV Read More: Euclid Mission: Science Goals http://sci.esa.int/euclid/42267-science/ "Until about thirty years ago astronomers thought that the Universe was composed almost entirely of ordinary matter: protons, neutrons, electrons and atoms. In the intervening years the emerging picture of the composition of the Universe has changed dramatically." What is Dark Energy? http://astronomy.swin.edu.au/cosmos/D/Dark+Energy "In the early part of the 20th century Albert Einstein had invoked a ‘cosmological constant’, (usually symbolized by the Greek letter lambda, Λ). It was a vacuum energy of empty space, which kept the universe (predicted by his field equations of the General Theory of Relativity) static, rather than contracting or expanding. It provided a way of balancing the gravitational contraction caused by matter. Once the universe was observed to be expanding Einstein hastily removed his cosmological constant." Euclid Consortium: A space mission to map the Dark Universe https://www.euclid-ec.org/ "Euclid is an ESA medium class astronomy and astrophysics space mission. Euclid was selected by ESA in October 2011 (see the Euclid ESA page). Its launch is planned for 2022. In June 2012 ESA officially selected the “Euclid Consortium” as the single team having the scientific responsibility of the mission, the data production and of the scientific instruments." ____________________ Countdown to Launch takes a deep dive into upcoming space missions from around the world.

NASA rover driver and robotics technologist Dr. Vandi Verma explains the behind-the-scenes of operating Mars spacecraft from Earth, as well as three big changes to expect with the Mars 2020 rover. How NASA Built the Fastest Spacecraft Ever -https://youtu.be/vcTQeqszsuw Read More The Space Roboticist: Dr. Vandi Verma https://www.sciencemag.org/careers/2015/07/space-roboticist She loves her day-to-day responsibility for the machine. “You definitely don’t want to be the one who drove the rover off a cliff! But I find it energizing rather than stressful. You’re completely focused.” Although human spacefaring has stalled, Verma says the spirit of exploration is alive and well in space robots. “I am happy to be working in robotics, pushing the envelope on space exploration,” Verma says. “We have reached Mars, our neighboring planet. We’ve have only just begun.” NASA Announces Landing Site for Mars 2020 Rover https://www.nasa.gov/press-release/nasa-announces-landing-site-for-mars-2020-rover "The rover mission is scheduled to launch in July 2020 as NASA’s next step in exploration of the Red Planet. It will not only seek signs of ancient habitable conditions – and past microbial life -- but the rover also will collect rock and soil samples and store them in a cache on the planet's surface. NASA and ESA (European Space Agency) are studying future mission concepts to retrieve the samples and return them to Earth, so this landing site sets the stage for the next decade of Mars exploration." Mars Helicopter to Fly on NASA’s Next Red Planet Rover Mission https://www.nasa.gov/press-release/mars-helicopter-to-fly-on-nasa-s-next-red-planet-rover-mission "The helicopter also contains built-in capabilities needed for operation at Mars, including solar cells to charge its lithium-ion batteries, and a heating mechanism to keep it warm through the cold Martian nights. But before the helicopter can fly at Mars it has to get there. It will do so attached to the belly pan of the Mars 2020 rover." ____________________ Science In The Extremes ventures to the ends of the earth to bring you pioneering research and innovations that are advancing our civilization and broadening our understanding of the universe.

What does a black hole look like? No one knows for sure. Artists make their images based on what physicists think they look like. But that could be about to change. This Is Not What Space Looks Like - https://youtu.be/N5rZ9E72zbI Read More: Scientists Wonder If the Collision of Two Neutron Stars Created a Black Hole https://www.seeker.com/space/astrophysics/scientists-wonder-if-the-collision-of-two-neutron-stars-created-a-black-hole “For the first time, scientists have seen the source of gravitational waves from two colliding neutron stars, and the space oddity doesn't stop there. Those neutron stars might have collapsed into a black hole after they merged, scientists say.” Gravitational Wave Kicks Monster Black Hole Out of Galactic Core https://www.nasa.gov/feature/goddard/2017/gravitational-wave-kicks-monster-black-hole-out-of-galactic-core “Astronomers have uncovered a supermassive black hole that has been propelled out of the center of a distant galaxy by what could be the awesome power of gravitational waves.” New Class of Black Hole 100,000 Times Larger Than the Sun Detected in Milky Way https://www.seeker.com/space/astronomy/new-class-of-black-hole-100000-times-larger-than-the-sun-detected-in-milky-way “Black holes are notoriously hard to find, since they don’t emit any light. But there’s one particular size of black hole that has been especially evasive, even though astronomers have theorized that they should be plentiful..” ____________________ Seeker inspires us to see the world through the lens of science and evokes a sense of curiosity, optimism and adventure.

Read More: What Are Saturn's Rings? https://www.livescience.com/60412-what-are-saturn-rings.html “The rings are mostly ice with a little bit of rock mixed in. Scientists have a better grasp of their dynamics than ever before, thanks to the Cassini spacecraft, which ends its mission on Friday (Sept. 15) with a plunge into Saturn's atmosphere, after 13 years of orbiting the planet.” Cassini Prepares to Crash Into Saturn as NASA Reflects on Mission's Discoveries https://www.seeker.com/space/planets/cassini-prepares-to-crash-into-saturn-as-nasa-reflects-on-missions-discoveries “The probe has spent more than a decade observing Saturn, studying storms in its cloud tops, learning about its strange, striped atmosphere, probing its cloaked interior and zipping through its more than 60 moons and a ring system stretching more than eight times the planet's radius.” Peculiar Waves in Saturn's Rings Spotted by NASA's Cassini Probe https://www.seeker.com/space/planets/peculiar-waves-in-saturns-rings-spotted-by-nasas-cassini-probe “The rings of Saturn are embedded with billions of water-ice particles ranging in size from grains of sand to monstrous chunks. Saturn's rings also feature waves that propagate outward in spiral patterns. The new image from Cassini captures an up-close view of a spiral density wave visible in Saturn's B ring.” ____________________ Seeker inspires us to see the world through the lens of science and evokes a sense of curiosity, optimism and adventure.

There are millions of giant rocks hurtling around the the solar system. Some of them stay in the cosmos and others penetrate the Earth’s atmosphere. So how do you tell the difference between different types of space rocks? The universe is kind of complicated, but Seeker has you covered. Each week, we’ll break down complex space terminology and phenomena using a very high tech medium… papier-mâché. You can get all kind of crafty in the cosmos with new episodes of Galactic Glossary every Wednesday.

Wild Stratospheric Balloon Ride Shows No Link Between Auroras and Radiation Flux https://www.seeker.com/space/exploration/wild-stratospheric-balloon-ride-shows-no-link-between-auroras-and-radiation-flux "An incredible flight in March 2017 set out to see if there is any correlation between auroras over Fairbanks, Alaska, and radiation flux in the stratosphere. While the team behind the autonomous stratospheric balloon ride couldn't establish a link, they came away from the experience with plenty of stories to tell - a lost balloon, an airplane search, and a six-mile, one-way hike to rescue their data." NASA Captures 'Spectacular' Views of Auroras on Uranus https://www.seeker.com/space/planets/nasa-captures-spectacular-views-of-auroras-on-uranus "Bright auroras light up the planet's atmosphere in two newly released photos, which combine observations by NASA's Hubble Space Telescope and the agency's Voyager 2 probe. (Voyager 2 flew by Uranus in 1986 as part of a "grand tour" of the solar system's outer planets that the spacecraft performed with its twin, Voyager 1.)" ____________________ Seeker inspires us to see the world through the lens of science and evokes a sense of curiosity, optimism and adventure.
