    ESA Euronews: Gaia’s revolution in astronomy

    Astronomy is undergoing a revolution with the release of precision data on 1.7 billion stars in our galaxy from the Gaia space telescope. We head to the historic Observatory of Paris and ESA’s ESTEC base in the Netherlands to find out more.

    It’s fair to say that science has been waiting for centuries, or even millennia for such a detailed survey of the Milky Way, and right now star-gazers are swamped with fresh, high-quality data that they can use to answer every question about the galaxy they ever wanted to ask.

  • Fly over Neukum crater

    Fly over Neukum crater

    This movie, based on images taken by ESA’s Mars Express, showcases the 102 km wide Neukum Crater in the southern hemisphere of Mars.

    The crater is named for the German physicist and planetary scientist, Gerhard Neukum, one of the founders of ESA’s Mars Express mission who inspired and led the development of the high-resolution stereo camera on Mars Express.

    This complex impact crater has a diverse geologic history, as indicated by various features on the crater rim and floor. Particularly striking are the dark dune fields, likely made up of volcanic material blown in and shaped by strong winds.

    The crater’s shallow interior has been infilled by sediments over its history. It is also marked with two irregular depressions that may be a sign of a weaker material that has since eroded away, leaving behind some islands of more resistant material.

    Over time the crater rim has undergone varying degrees of collapse, with landslides and slumped material visible in the crater walls. Many smaller craters have also overprinted the rim and pockmarked the interior since Neukum Crater was formed, highlighting its long history.

    Neukum Crater is situated in Noachis Terra, one of the oldest known regions on Mars, dating back to at least 3.9 billion years.

  • Mars sample return

    Mars sample return

    Spacecraft in orbit and on Mars’s surface have made many exciting discoveries, transforming our understanding of the planet and unveiling clues to the formation of our Solar System, as well as helping us understand our home planet. The next step is to bring samples to Earth for detailed analysis in sophisticated laboratories where results can be verified independently and samples can be reanalysed as laboratory techniques continue to improve.

    Bringing Mars to Earth is no simple undertaking—it would require at least three missions from Earth and one never-been-done-before rocket launch from Mars.

    A first mission, NASA’s 2020 Mars Rover, is set to collect surface samples in pen-sized canisters as it explores the Red Planet. Up to 31 canisters will be filled and readied for a later pickup – geocaching gone interplanetary.

    In the same period, ESA’s ExoMars rover, which is also set to land on Mars in 2021, will be drilling up to two meters below the surface to search for evidence of life.

    A second mission with a small fetch rover would land nearby and retrieve the samples in a Martian search-and-rescue operation. This rover would bring the samples back to its lander and place them in a Mars Ascent Vehicle – a small rocket to launch the football-sized container into Mars orbit.

    A third launch from Earth would provide a spacecraft sent to orbit Mars and rendezvous with the sample containers. Once the samples are safely collected and loaded into an Earth entry vehicle, the spacecraft would return to Earth, release the vehicle to land in the United States, where the samples will be retrieved and placed in quarantine for detailed analysis by a team of international scientists.

  • Sentinel-3B highlights

    Sentinel-3B highlights

    The Copernicus Sentinel-3B satellite spent six weeks at the Plesetsk cosmodrome in Russia being carefully prepared for liftoff. After being shipped from France to the launch site, the satellite was tested, joined to the rocket launch adapter, sealed from view in the fairing and taken by train to the launch pad. Sentinel-3B lifted off on 25 April 2018 at 17:57 GMT (19:57 CEST).

    It joins its twin, Sentinel-3A, in orbit. The pairing of identical satellites provides the best coverage and data delivery for Europe’s Copernicus programme – the largest environmental monitoring programme in the world. The satellites carry the same suite of cutting-edge instruments to measure oceans, land, ice and atmosphere. While these data are fed primarily into the Copernicus Marine Environment Monitoring Service, all the Copernicus services benefit to produce knowledge and information products in near-real time for a wide range of applications. The Sentinel-3 mission is essential for applications for ocean and coastal monitoring, numerical weather and ocean prediction, sea-level change and sea-surface topography monitoring, ocean primary production estimation and land-cover change mapping.

  • Gaia second data release

    Gaia second data release

    The second data release of ESA’s Gaia mission has produced an extraordinary catalogue of over one and a half billion stars in our galaxy. Based on observations between July 2014 to May 2016, it includes the most accurate information yet on the positions, brightness, distance, motion, colour and temperature of stars in the Milky Way as well as information on asteroids and quasars.

  • The Hyades cluster

    The Hyades cluster

    Animated 3D view of the sky as observed by ESA’s Gaia satellite using information from the mission’s second data release.

    The bright band in the left half of the image is the Milky Way, where most of the stars in our Galaxy reside. The animation starts with the Orion constellation at the centre; we then move towards the neighbouring Taurus constellation and to the Hyades star cluster, which is part of this constellation. Hyades is the closest open cluster to the Solar System, some 150 light-years away.

    The animation first shows the 3D structure of the cluster, based on accurate position and distance information from Gaia. Then an animated view of the future motions of stars is shown – both in Hyades and beyond. This is based on Gaia’s measurements of the velocity of stars across the sky, also known as proper motion.

  • 360º Parallax and proper motion on the sky

    360º Parallax and proper motion on the sky

    A 360° animated view of the entire sky on 25 April 2018.

    After a few seconds, the stars start moving in the sky according to parallax, an apparent shift caused by Earth’s yearly motion around the Sun. Then, constellation outlines appear as visual aids. Finally, stars start moving according to their true motion through space, which is visible on the sky as proper motion. Parallaxes have been exaggerated by 100 000 and proper motions have been speeded up by one trillion (10^12) to make them visible in this animation. This animation is based on data from the second data release of ESA’s Gaia satellite, which has measured the positions, parallaxes and motions of more than one billion stars across the sky to unprecedented accuracy.

In the extreme environment of a neutron star’s core, sound can travel extremely fast. But knowing that sound can’t surpass the speed of light, physicists can narrow down their models of neutron stars to include only those where “extremely fast” is less than light speed.

  • ESA reentry expertise

    ESA reentry expertise

    Every week, on average, a substantial, inert satellite drops into our atmosphere and burns up. Monitoring these reentries and warning European civil authorities has become routine work for ESA’s space debris experts.

    Each year, about 100 tonnes of defunct satellites, uncontrolled spacecraft, spent upper stages and discarded items like instrument covers are dragged down by Earth’s upper atmosphere, ending their lives in flaming arcs across the sky.

    Some of these objects are big and chunky, and pieces of them survive the fiery reentry to reach the surface. Our planet, however, is a big place, mostly covered by water, and much of what falls down is never seen by anyone, sinking to the bottom of some ocean, or landing far from human habitation.

    While still in orbit, these and many other objects are tracked by a US military radar network, which shares the data with ESA, since Europe has no such capability of its own.It’s the task of ESA’s Space Debris team to look at these data and issue updates to ESA Member States and partner civil authorities around the globe.

    Geology experts from ESA’s Pangaea-X campaign mapped most of the lava tube system as part of a project supported by local authorities Cabildo of Lanzarote and the University of Padova, Italy. The data was acquired in November 2017 by Leica Geosystems.

    The map comes alive in great detail in 3D, helping institutions to protect the subterranean environment. The map also provides scientific data to study the origins of the tube and its peculiar formations.

    Pangaea-X is a test campaign that brings together geology, high-tech survey equipment and space exploration. Learn more about the science and technology behind this campaign visiting http://blogs.esa.int/pangaea

    What is Dark Matter? A New Clue!

    Scientists may have found clues to the nature of dark matter in a signal from the universe’s first stars.

    Here is the research paper: https://www.nature.com/articles/nature25792
    Authors: Judd D. Bowman, Alan E. E. Rogers, Raul A. Monsalve, Thomas J. Mozdzen & Nivedita Mahesh

    This evidence seems to suggest that the dark matter is particles that are less than four times the mass of a proton and are moving at non-relativistic speeds. This is consistent with dark matter particles being so-called WIMPs: https://en.wikipedia.org/wiki/Weakly_interacting_massive_particles.

  • Phobos and Saturn

    Phobos and Saturn

    These observations of Phobos and Saturn were taken by the Super Resolution Channel of the High Resolution Stereo Camera on Mars Express. The video comprises 30 separate images acquired during Mars Express orbit 16 346 on 26 November 2016. The slight up and down movement of Saturn and Phobos in these images is caused by the oscillation of the spacecraft’s orientation after completing the turn towards the moon. Phobos can be seen in the foreground, partially illuminated, with Saturn visible as a small ringed dot in the distance.

    ESA astronaut Luca Parmitano talks science in space

    From ESA astronaut Luca Parmitano’s hometown in Catania, Italy, Luca talks about the science he ran on the International Space Station.

    The European laboratory Columbus was launched in 2008 and offers scientists a permanent place in space to conduct research that is out of this world.

    Luca’s first spaceflight was in 2013 with Russian cosmonaut Fyodor Yurchikhin and NASA astronaut Karen Nyberg. He conducted over 20 experiments during the Volare mission as flight engineer for Expeditions 36 and 37 and he was the first of ESA’s new generation of astronauts to fly into space.

    Luca talks about space research, being a human guinea pig, dieting to avoid bone disease osteoporosis, human physiology, using ultrasound remotely to diagnose back problems, measuring eye pressure and how his body and mind reacted to living in weightlessness.

    Luca is set for a second mission to the International Space Station in 2019.

  • ExoMars Trace Gas Orbiter completes aerobraking

    ExoMars Trace Gas Orbiter completes aerobraking

    Since arriving at Mars in October 2016, the ExoMars Trace Gas Orbiter has been aerobraking its way into a close orbit of the Red Planet by using the top of the atmosphere to create drag and slow down. It is almost in the right orbit to begin observations – only a few hundred kilometres to go! With aerobraking complete, additional manoeuvres will bring the craft into a near-circular two-hour orbit, about 400 km above the planet, by the end of April. The mission’s main goal is to take a detailed inventory of the atmosphere, sniffing out gases like methane, which may be an indicator of active geological or biological activity. The camera will help to identify surface features that may be related to gas emissions. The spacecraft will also look for water-ice hidden below the surface, which could influence the choice of landing sites for future exploration. It will also relay large volumes of science data from NASA’s rovers on the surface back to Earth and from the ESA–Roscosmos ExoMars rover, which is planned for launch in 2020.

  • Profiling the wind

    Profiling the wind

    ESA’s Earth Explorer Aeolus satellite will be launched later this year to measure the world’s winds from space. The satellite carries one of the most sophisticated instruments ever to be put into orbit: Aladin, which includes two powerful lasers, a large telescope and very sensitive receivers. The laser generates ultraviolet light that is beamed down into the atmosphere to profile the world’s winds – a completely new approach to measuring the wind from space. These vertical slices through the atmosphere, along with information it gathers on aerosols and clouds, will improve our understanding of atmospheric dynamics and contribute to climate research. As well as advancing science, Aeolus will play an important role in improving weather forecasts. The mission will also complement information about the atmosphere being provided by the Copernicus Sentinel missions.
