Gaia untangles the starry strings of the Milky Way Rather than leaving home young, as expected, stellar ‘siblings’ prefer to stick together in long-lasting, string-like groups, finds a new study of data from ESA’s Gaia spacecraft. Exploring the distribution and past history of the starry residents of our galaxy is…View More Gaia untangles the starry strings of the Milky Way
Unexpected periodic flares may shed light on black hole accretion ESA’s X-ray space telescope XMM-Newton has detected never-before-seen periodic flares of X-ray radiation coming from a distant galaxy that could help explain some enigmatic behaviours of active black holes. XMM-Newton, the most powerful X-ray observatory, discovered some mysterious flashes from…View More Unexpected periodic flares may shed light on black hole accretion
NASA Selects Proposals to Advance Understanding of Space Weather NASA has selected three proposals for concept studies of missions that could help us better understand the dynamic space weather system driven by the Sun that manifests near Earth. The proposals examine what drives different parts of that system and ultimately…View More NASA Selects Proposals to Advance Understanding of Space Weather

Gaia starts mapping our galaxy’s bar The first direct measurement of the bar-shaped collection of stars at the centre of our Milky Way galaxy has been made by combining data from ESA’s Gaia mission with complementary observations from ground- and space-based telescopes. Revealing the galactic barThis colour chart shows…View More Gaia starts mapping our galaxy’s bar

Reforesting an area the size of the US needed to help avert climate breakdown, say researchers – are they right? Inga Linder/Shutterstock Mark Maslin, UCL and Simon Lewis, UCL Restoring the world’s forests on an unprecedented scale is “the best climate change solution available”, according to a new study. The…View More Reforesting an area the size of the US needed to help avert climate breakdown, say researchers – are they right?

Curious Kids: why has nobody found any life outside of Earth? An artist’s impression of Kepler-22b, a planet known to comfortably circle in the habitable zone of a sun-like star. It is the first planet that NASA’s Kepler mission has confirmed to orbit in a star’s habitable zone – the…View More Curious Kids: why has nobody found any life outside of Earth?
