NASA's Goddard Space Flight Center 25 Apr 2018, 13:43 UTC The first stars in the universe blazed to life about 200 to 400 million years after the big bang. Observing those very first individual stars across such vast distances of space normally would be a feat beyond any space science telescope. However, new theoretical work suggests that under the right circumstances, and with a little luck, NASA’s upcoming James Webb Space Telescope will be able to capture light from single stars within that first generation of stars.
ESA Top News 25 Apr 2018, 10:00 UTC ESA’s Gaia mission has produced the richest star catalogue to date, including high-precision measurements of nearly 1.7 billion stars and revealing previously unseen details of our home Galaxy. A multitude of discoveries are on the horizon after this much awaited release, which is based on 22 months of charting the sky. The new data includes positions, distance indicators and motions of more than one billion stars, along with high-precision measurements of asteroids within our Solar System and stars beyond our own Milky Way Galaxy.
NASA's Jet Propulsion Laboratory News and Features 24 Apr 2018, 18:56 UTC Even after decades of observations and a visit by NASA's Voyager 2 spacecraft, Uranus held on to one critical secret -- the composition of its clouds. Now, one of the key components of the planet's clouds has finally been verified.
NASA's Goddard Space Flight Center 24 Apr 2018, 14:38 UTC Any telescope that reaches the launch pad in the 2030s likely will look much different than the concepts four teams are currently studying to inform the 2020 Decadal Survey for Astrophysics, but the studies do offer a roadmap. Here’s a brief overview of each:
NASA's Jet Propulsion Laboratory News and Features 19 Apr 2018, 19:04 UTC Many of NASA's most iconic spacecraft towered over the engineers who built them: think Voyagers 1 and 2, Cassini or Galileo -- all large machines that could measure up to a school bus. But in the past two decades, mini-satellites called CubeSats have made space accessible to a new generation. These briefcase-sized boxes are more focused in their abilities and have a fraction of the mass -- and cost -- of some past titans of space.
Hubble Space Telescope News 19 Apr 2018, 14:00 UTC This colourful cloud of glowing interstellar gas is just a tiny part of the Lagoon Nebula, a vast stellar nursery. This nebula is a region full of intense activity, with fierce winds from hot stars, swirling chimneys of gas, and energetic star formation all embedded within a hazy labyrinth of gas and dust. Hubble used both its optical and infrared instruments to study the nebula, which was observed to celebrate Hubble’s 28th anniversary.
German Aerospace Center (DLR) 19 Apr 2018, 10:57 UTC The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and the United States corporation Teledyne Brown Engineering (TBE) are announcing the completion of the development and manufacturing process of the DESIS hardware. Operating the DLR Earth Sensing Imaging Spectrometer (DESIS) on the International Space Station (ISS) makes DLR the first user of the revolutionary multiplatform system MUSES (Multi User System for Earth Sensing) that was installed on board the ISS in 2017. The launch of the DESIS joint venture is scheduled for summer 2018 from Cape Canaveral and will be lifted into space by a SpaceX Falcon 9 rocket.
