From the European Space Agency (ESA): “The PLAnetary Transits and Oscillations of stars (PLATO) mission will identify and study thousands of exoplanetary systems, with an emphasis on discovering and characterising Earth-sized planets and super-Earths. It will also investigate seismic activity in stars, enabling a precise characterisation of the host sun of each planet discovered, [...]
This image of the galaxy cluster Abell 2744 was obtained with NASA’s Hubble Space Telescope, as part of the Frontier Fields program, designed to push the limits of how far we can see into the early universe. The zoomed image shows the region around the galaxy Abell2744_Y1, one of the most distant galaxy candidates [...]

Originally perceived by astronomers as a space mission that was unlikely to ever happen, the European Space Agency’s [...]
The European Space Agency’s PLATO mission aims to discover and characterize hundreds of Earth-sized exoplanets inside the habitable zones of approximately 1 million stars. The mission is likely to be approved for implementation by ESA during an announcement due for next week. Image Credit: PLATO Definition Study Report/ESA

A false-color photograph of Uranus, its rings, and 10 of its moons, taken by the Hubble Space Telescope’s Near Infrared Camera and Multi-Object Spectrometer in near-infrared wavelengths. As seen in this photo, there’s so much more to see on Uranus than meets the eye. This enigmatic world deserves a dedicated space mission to be [...]

A new study published online in the weekly scientific journal Nature on Jan. 22 reports on observations made by the Herschel Space Observatory of water vapour seen coming out [...]
Rosetta and its Philae landing craft will arrive at Comet 67P/Churyumov-Gerasimenko in 2014. Yesterday’s successful restoration of communications with the spacecraft is the first critical step on our exciting journey to orbit and land on a comet for the first time in human history.

Rosetta and its Philae landing craft will arrive at Comet 67P/Churyumov-Gerasimenko in 2014. On Monday, 20 January, the craft is due to be revived from its 2.5-year deep-space hibernation. Image Credit: ESA
According to the Brothers Grimm, Sleeping Beauty was condemned to sleep for 100 years, but the European Space Agency (ESA) will act [...]
A long-exposure image of galaxy cluster Abell 2744, obtained by the Hubble Space Telescope, as part of the Hubble Frontier Fields program. The long blue streaks surrounding the cluster in the image come from the light of much more distant galaxies, located as far as 13 billion light-years away behind the cluster. Image Credit: [...]
