NASA's Goddard Space Flight Center 16 Feb 2018, 14:28 UTC This image from the NASA/ESA Hubble Space Telescope shows the galaxy cluster PLCK G004.5-19.5. It was discovered by the ESA Planck satellite through the Sunyaev-Zel’dovich effect — the distortion of the cosmic microwave background radiation in the direction of the galaxy cluster by high-energy electrons in the intracluster gas. The large galaxy at the center is the brightest galaxy in the cluster, and above it a thin, curved gravitational lens arc is visible. This arc is caused by the gravitational forces of the cluster bending the path of light from stars and galaxies behind it, in a similar way to how a glass lens bends light.
NASA's Goddard Space Flight Center 15 Feb 2018, 18:00 UTC Three billion miles away on the farthest known major planet in our solar system, an ominous, dark storm – once big enough to stretch across the Atlantic Ocean from Boston to Portugal – is shrinking out of existence as seen in pictures of Neptune taken by NASA’s Hubble Space Telescope.
NASA's Chandra X-ray Observatory 15 Feb 2018, 16:10 UTC The biggest black holes in the Universe are growing faster than the rate of stars being formed in their galaxies, according to two new studies using data from NASA's Chandra X-ray Observatory and other telescopes.

ESA Top News 15 Feb 2018, 08:10 UTC A new international accelerator, the Facility for Antiproton and Ion Research (FAIR), now under construction near Darmstadt, Germany, at the existing GSI Helmholtz Centre for Heavy Ion Research (GSI), will provide particle beams like the ones that exist in space and make them available to scientists for studies that will be used to make spacecraft more robust and help humans survive the rigours of spaceflight.
Hubble Space Telescope News 14 Feb 2018, 15:00 UTC Beauty, grace, mystery — this magnificent spiral galaxy has all the qualities of a perfect galactic Valentine. Captured by the NASA/ESA Hubble Space Telescope, the galaxy NGC 3344 presents itself face-on, allowing astronomers a detailed look at its intricate and elegant structure. And Hubble’s ability to observe objects over a wide range of different wavelengths reveals features that would otherwise remain invisible.
NASA's Goddard Space Flight Center 14 Feb 2018, 14:53 UTC As part of an engineering test, NASA’s OSIRIS-REx spacecraft captured this image of the Earth and Moon using its NavCam1 imager on January 17 from a distance of 39.5 million miles (63.6 million km). When the camera acquired the image, the spacecraft was moving away from home at a speed of 19,000 miles per hour (8.5 kilometers per second).
NASA's Jet Propulsion Laboratory News and Features 13 Feb 2018, 20:02 UTC A chunk of Mars will soon be returning home. A piece of a meteorite called Sayh al Uhaymir 008 (SaU008) will be carried on board NASA's Mars 2020 rover mission, now being built at the agency's Jet Propulsion Laboratory in Pasadena, California. This chunk will serve as target practice for a high-precision laser on the rover's arm.
ESO Top News 13 Feb 2018, 14:00 UTC The ESPRESSO instrument on ESO’s Very Large Telescope in Chile has for the first time been used to combine light from all four of the 8.2-metre Unit Telescopes. Combining light from the Unit Telescopes in this way makes the VLT the largest optical telescope in existence in terms of collecting area.
