Mysteriously in-sync pulsar challenges existing theories
13 September 2019

For the first time, astronomers have detected synchronised pulses of optical and X-ray radiation from a mysterious pulsar some 4500 light years away. The observations indicate that a new physical mechanism might be needed to explain the behaviour of fast-spinning sources like this one, known as transitional millisecond pulsars.

Hubble reveals latest portrait of Saturn [heic1917]
12 September 2019

The NASA/ESA Hubble Space Telescope's Wide Field Camera 3 observed Saturn on 20 June 2019 as the planet made its closest approach to Earth this year, at approximately 1.36 billion kilometres away.

Hubble finds water vapour on habitable-zone exoplanet for the first time [heic1916]
11 September 2019

With data from the NASA/ESA Hubble Space Telescope, water vapour has been detected in the atmosphere of a super-Earth within the habitable zone by University College London (UCL) researchers in a world first.

Unexpected periodic flares may shed light on black hole accretion
11 September 2019

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.

Hubble explores the formation and evolution of star clusters in the Large Magellanic Cloud [heic1915]
9 September 2019

Just as people of the same age can vary greatly in appearance and shape, so do collections of stars or stellar aggregates. New observations from the NASA/ESA Hubble Space Telescope suggest that chronological age alone does not tell the complete story when it comes to the evolution of star clusters.

Cluster and XMM-Newton pave the way for SMILE
27 August 2019The Solar wind-Magnetosphere-Ionosphere Link Explorer (SMILE) mission is still four years away from launch, but scientists are already using existing ESA satellites, such as the XMM-Newton X-ray observatory and the Cluster mission studying Earth's magnetosphere, to pave the way for this pioneering venture.
Shedding light on white dwarfs – the future of stars like our Sun
17 May 2019ESA's Gaia mission has been busy mapping our Milky Way galaxy since 2014, and just over one year ago released its second batch of data on more than one billion stars. Since then, astronomers have been exploring this catalogue to reveal a huge amount of new information about the cosmos. One type of object that has seen an abundance of new...
How Venus and Mars can teach us about Earth
13 May 2019One has a thick poisonous atmosphere, one has hardly any atmosphere at all, and one is just right for life to flourish – but it wasn't always that way. The atmospheres of our two neighbours Venus and Mars can teach us a lot about the past and future scenarios for our own planet.

#4: Simulating zero gravity
2 August 2019Like most spacecraft, ESA's Solar Orbiter carries a number of deployable structures that play key roles in the success of its mission. Earlier this year, engineers completed a series of deployment tests on the spacecraft's antennas, instrument boom and solar arrays.
#17: Practice makes perfect for CHEOPS inflight operations
25 June 2019It takes collaboration and teamwork to operate a spacecraft. As the CHEOPS launch approaches, a Europe-wide team is preparing to take control of inflight activities once the satellite is in space.
#4: JUICE engineering model ready for testing
11 December 2018The JUICE engineering model spacecraft test readiness review was completed successfully on 2 October, and the first engineering model instruments are now being delivered and tested.
