Astronomers have discovered some of the oldest stars in the galaxy, whose chemical composition and movements could tell us what the Universe was like soon after the Big Bang.
An international team of astronomers led by the University of Cambridge have detected the most distant clouds of star-forming gas yet found in normal galaxies in the early Universe – less than one billion years after the Big Bang. The new observations will allow astronomers to start to see how the first galaxies were built up and how they cleared the cosmic fog during the era of reionisation. This is the first time that such galaxies have been seen as more than just faint blobs.
A Cambridge-led outreach project is connecting over 2,200 pupils with the excitement of ESA’s Gaia mission through a Q&A session that will take place tomorrow with the discussion streamed live to schools throughout Europe.
A space mission to create the largest, most-accurate, map of the Milky Way in three dimensions has been launched today. Astronomers say the data gathered by the satellite will “revolutionise” our understanding of the galaxy and the universe beyond.
This week, work begins on the next phase of development for the Square Kilometre Array radio telescope, with the University of Cambridge leading major ‘work packages’.
Satellite’s first all-sky image is the most detailed picture to date of the early Universe, giving us a better understanding of its birth.
