Harvard-Smithsonian Center for Astrophysics 29 Jun 2018, 12:41 UTC A new study provides new clues indicating that an exoplanet 500 light-years away is much like Earth. Kepler-186f is the first identified Earth-sized planet outside the Solar System orbiting a star in the habitable zone. This means it's the proper distance from its host star for liquid water to pool on the surface.
NASA's Goddard Space Flight Center 29 Jun 2018, 12:00 UTC This rich and dense smattering of stars is a massive globular cluster, a gravitationally bound collection of stars that orbits the Milky Way. Globular clusters are denser and more spherical than open star clusters like the famous Pleiades. They typically contain hundreds of thousands of stars that are thought to have formed at roughly the same time.
ESA Top News 28 Jun 2018, 08:00 UTC After completion of an independent review, a new launch date for the James Webb Space Telescope has been announced: 30 March 2021. "The James Webb Space Telescope is the most ambitious and complex astronomical project ever built, and bringing it to life is a long, meticulous process. The wait will be a little longer now but the breakthrough science that it will enable is absolutely worth it," says Günther Hasinger, ESA Director of Science.
ESA Top News 27 Jun 2018, 17:00 UTC Data from the international Cassini spacecraft have revealed complex organic molecules originating from Saturn’s icy moon Enceladus, strengthening the idea that this ocean-world hosts conditions suitable for life.
ESO Top News 27 Jun 2018, 17:00 UTC `Oumuamua, the first interstellar object discovered in the Solar System, is moving away from the Sun faster than expected. This anomalous behaviour was detected by a worldwide astronomical collaboration including ESO’s Very Large Telescope in Chile. The new results suggest that `Oumuamua is most likely an interstellar comet and not an asteroid. The discovery appears in the journal Nature.
NASA's Goddard Space Flight Center 25 Jun 2018, 15:41 UTC In the last decade we have discovered thousands of planets outside our solar system and have learned that rocky, temperate worlds are numerous in our galaxy. The next step will involve asking even bigger questions. Could some of these planets host life? And if so, will we be able to recognize life elsewhere if we see it?
NASA's Goddard Space Flight Center 25 Jun 2018, 15:00 UTC Jupiter’s iconic storm is on the Webb telescope’s list of targets chosen by guaranteed time observers, scientists who helped develop the incredibly complex telescope and among the first to use it to observe the universe. One of the telescope’s science goals is to study planets, including the mysteries still held by the planets in our own solar system from Mars and beyond.
ESA Top News 25 Jun 2018, 07:25 UTC As if this Hubble Space Telescope picture isn't cluttered enough with myriad galaxies, nearby asteroids photobomb the image, their trails sometimes mimicking background astronomical phenomena. The stunningly beautiful galaxy cluster Abell 370 contains an astounding assortment of several hundred galaxies tied together by the mutual pull of gravity. Located approximately four billion light years away in the constellation Cetus, the Sea Monster, this immense cluster is a rich mix of a variety of galaxy shapes.
NASA's Goddard Space Flight Center 22 Jun 2018, 13:55 UTC In astronomy, the devil is in the details — as this image, taken by the NASA/ESA (European Space Agency) Hubble Space Telescope’s Advanced Camera for Surveys and Wide-Field Camera 3, demonstrates. The numerous fuzzy blobs and glowing shapes scattered across this image make up a galaxy cluster named RXC J0949.8+1707. Located to the upper right of the frame sits an especially beautiful and interesting barred spiral galaxy, seen face-on. In the past decade, astronomers peering at this galaxy have possibly discovered not one but three examples of a cosmic phenomenon known as a supernova, the magnificently bright explosion of a star nearing the end of its life.
