ESA Top News 20 Nov 2017, 08:30 UTC ESA’s Integral space observatory has been orbiting Earth for 15 years, observing the ever-changing, powerful and violent cosmos in gamma rays, X-rays and visible light. Studying stars exploding as supernovas, monster black holes and, more recently, even gamma-rays that were associated with gravitational waves, Integral continues to broaden our understanding of the high-energy Universe.

Europlanet Research Infrastructure 19 Nov 2017, 09:59 UTC We’ve said goodbye to Cassini. What comes next? Prof. Nick Achilleos (left), Anastasia Kokori (centre) and Dr. Patrick Guio (right) at UCL. Anastasia Kokori has participated in an expert exchange programme at in the department of astrophysics at UCL. The Cassini mission, a collaborative effort between NASA, the European Space Agency, and the Italian Space Agency, said goodbye on the 15th of September 2017. The mission reached an end after 13 years of orbiting around Saturn, proving us with a large legacy of data that is still being analysed, and will keep scientists occupied for many years to come. The research of the Planetary Plasma Physics Group at UCL focuses on the two gas giant planets of our Solar System, Jupiter and Saturn. The team, which currently consists of five members, studies the magnetic fields of these planets by applying models which help us better understand the observations made by spacecraft like Cassini. Prof. Nick Achilleos highlights that one of the major discoveries of Cassini was the observation of water plumes erupting from Enceladus, the sixth largest moon of Saturn. Until Cassini arrived there, it was not known that Enceladus was a very geologically active moon. “The discovery of water ...

NASA's Goddard Space Flight Center 17 Nov 2017, 13:44 UTC This new picture of the week, taken by the NASA/ESA Hubble Space Telescope, shows the dwarf galaxy NGC 4625, located about 30 million light-years away in the constellation of Canes Venatici (The Hunting Dogs). The image, acquired with the Advanced Camera for Surveys (ACS), reveals the single major spiral arm of the galaxy, which gives it an asymmetric appearance. But why is there only one such spiral arm, when spiral galaxies normally have at least two?
NCCR PlanetS 17 Nov 2017, 07:28 UTC A temperate Earth-sized planet has been discovered only 11 light-years from the Solar System by a team including member of PlanetS using ESO’s unique planet-hunting HARPS instrument. The new world has the designation Ross 128 b and is now the second-closest temperate planet to be detected after Proxima b. It is also the closest planet to be discovered orbiting an inactive red dwarf star, which may increase the likelihood that this planet could potentially sustain life. Ross 128 b will be a prime target for ESO’s Extremely Large Telescope, which will be able to search for biomarkers in the planet’s atmosphere. A team working with ESO’s High Accuracy Radial velocity Planet Searcher (HARPS) at the La Silla Observatory in Chile has found that the red dwarf star Ross 128 is orbited by a low-mass exoplanet every 9.9 days. This Earth-sized world is expected to be temperate, with a surface temperature that may also be close to that of the Earth. Ross 128 is the “quietest” nearby star to host such a temperate exoplanet. This artist’s impression shows the temperate planet Ross 128 b, with its red dwarf parent star in the background. This planet, which lies only 11 light-years from ...
NASA Breaking News 16 Nov 2017, 21:05 UTC NASA has selected a science instrument for an upcoming Japan-led sample return mission to the moons of Mars planned for launch in 2024. The instrument, a sophisticated neutron and gamma-ray spectrograph, will help scientists resolve one of the most enduring mysteries of the Red Planet -- when and how the small moons formed.
NASA's Jet Propulsion Laboratory News and Features 16 Nov 2017, 16:38 UTC Twice as big as Earth, the super-Earth 55 Cancri e was thought to have lava flows on its surface. The planet is so close to its star, the same side of the planet always faces the star, such that the planet has permanent day and night sides. Based on a 2016 study using data from NASA's Spitzer Space Telescope, scientists speculated that lava would flow freely in lakes on the starlit side and become hardened on the face of perpetual darkness. The lava on the dayside would reflect radiation from the star, contributing to the overall observed temperature of the planet.
