  • 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.

  • Gaia’s first asteroid survey

    Gaia’s first asteroid survey

    Animated view of 14 099 asteroids in our Solar System, as viewed by ESA’s Gaia satellite using information from the mission’s second data release. The orbits of the 200 brightest asteroids are also shown, as determined using Gaia data.

    In future data releases, Gaia will also provide asteroid spectra and enable a complete characterisation of the asteroid belt. The combination of dynamical and physical information that is being collected by Gaia provides an unprecedented opportunity to improve our understanding of the origin and the evolution of the Solar System.

  • 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.

  • To Europe’s spaceport!

    To Europe’s spaceport!

    Meet our new space explorers, the spacecraft of the BepiColombo mission, as they begin their adventure to planet Mercury. But first, they have to navigate through Amsterdam Schiphol airport to reach Europe’s spaceport in Kourou, French Guiana.

    The spacecraft really do depart from Schiphol; along with essential ground-support equipment they are scheduled to fly in a series of Antonov aircraft during the last week of April and first week of May. Upon arrival at Kourou, an intensive six-months of preparations will prepare the mission for launch. The launch window opens 5 October until 29 November 2018.

  • Waiting for Gaia

    Waiting for Gaia

    On 25 April 2018, ESA’s Gaia mission will publish its much awaited second data release, including high-precision measurements of nearly 1.7 billion stars in our Galaxy.

    Scientists who have been working on creating and validating the data contained in the catalogue tell us why they are waiting for this extraordinary release.

    Featured in the video: Antonella Vallenari (INAF, Astronomical Observatory of Padua), Anthony Brown (Leiden University), Timo Prusti (European Space Agency), Annie Robin (Institut UTINAM, OSU THETA Franche-Comté-Bourgogne), Laurent Eyer (University of Geneva) and Federica Spoto (IMCCE, Observatory of Paris).

    A media briefing on the second Gaia data release will be held at the ILA Berlin Air and Space Show in Germany on 25 April 11:00-12:15 CEST. Watch the webstream at www.esa.int/live

  • ESA Euronews: Surfing scientists

    ESA Euronews: Surfing scientists

    We meet a surfing scientist and toxic algae hunters to see how Sentinel-3 satellite data is used to study the coastline of the English Channel in this month’s episode of Space.

    Bob Brewin is pioneering a new technique in satellite oceanography – by going surfing.
    The Plymouth Marine Laboratory scientist uses his board to take sea surface temperature measurements, and then use them to better interpret data from European satellite Sentinel-3.

  • What is Dark Matter? A New Clue!

    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.
    – Subscribe: https://www.youtube.com/WhatThePhysics?sub_confirmation=1

    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.

  • The value of the Moon with Paul D. Spudis | Space Bites

    The value of the Moon with Paul D. Spudis | Space Bites

    The Moon is a destination, a laboratory for science, a place to learn the skills of planetary exploration, and a source of materials and energy for use on the Moon and in space to create new spacefaring capability.

    Advocate of a human return on the Moon, Paul D. Spudis, Senior Staff Scientist at the Lunar and Planetary Institute in Houston (Texas, USA), takes us on a journey to rediscover the value of lunar exploration, a topic on which he has spent more than 40 years of study, thought and publications.

    Space Bites hosts the best talks on space exploration from the most inspiring and knowledgeable speakers from the field. Held at the technical heart of the European Space Agency in the Netherlands, the lectures are now also available on YouTube. If you want to know about the present and future challenges of ESA, stay tuned for more.
