- Herschel:Rare merger illuminates origin of 'red and dead' galaxies Astronomers have found a rare encounter between two massive and gas-rich galaxies in a survey from Herschel. The event took place when the Universe was only about three billion years old and involved two galaxies forming stars with exceptional efficiency whilst in the process of merging. This galactic collision would go on to form a very massive elliptical galaxy with hardly any star formation activity. The discovery suggests a viable mechanism for the origin of the puzzling 'red and dead' galaxies that are seen in the young Universe.
- Venus Express:No. 256 – Continuation of the fourteenth Earth occultation season, start of the twenty-third eclipse season, and start of surface imaging campaign Report for the period 6 January to 2 February 2013 This reporting period covers four weeks of Venus Express operations, from 6 January to 2 February 2013, and includes the continuation of the fourteenth occultation season, the start of the twenty-third eclipse season, and start of the Venus surface imaging campaign.
- Cosmic Vision:Call for White Papers for the definition of the L2 and L3 missions in the ESA Science Programme The Director of Science and Robotic Exploration intends to define, in the course of 2013, the science themes and questions that will be addressed by the next two Large (L-class) missions in the Cosmic Vision 2015-2025 plan, "L2" and "L3", currently planned for a launch in 2028 and 2034, respectively. This process starts with a consultation of the broad scientific community, in the form of the current Call, soliciting White Papers to propose science themes and associated questions that the L2 and L3 missions should address. The submission deadline for White Papers is 24 May 2013, 12:00 CEST (noon).
- Herschel:Herschel Status Report - February 2013 Report for period 5 to 27 February 2013 Mission operations of the Herschel space observatory continued nominally during the reporting period, with the spacecraft and subsystems all performing as expected.
- Hubble:Most detailed observations ever of the Ring Nebula [heic1310] The NASA/ESA Hubble Space Telescope has produced the most detailed observations ever of the Ring Nebula (Messier 57). This image reveals intricate structure only hinted at in previous observations, and has allowed scientists to construct a model of the nebula in 3D - showing the true shape of this striking object.
- Herschel:Herschel Status Report - December 2012 and January 2013 Report for period 6 December 2012 to 4 February 2013Mission operations of the Herschel space observatory continued nominally during the reporting period, with the spacecraft and subsystems all performing as expected.
- Herschel:Herschel reveals the Milky Way's warm heart What heats gas near supermassive black holes at the centre of galaxies? Astronomers have looked at the centre of our Galaxy, the Milky Way, with ESA's Herschel Space Observatory and discovered a rich variety of molecules at surprisingly high temperatures - up to 1000 K. The new data suggest that the molecular gas is heated up by shocks, in addition to ultraviolet radiation from massive stars close to the Galactic Centre. Shocks develop in the gas as the material surges towards Sagittarius A*, the region harbouring the supermassive black hole at the heart of the Milky Way.
- Venus Express:No. 255 - Start of the fourteenth Earth occultation season, completion of the tenth Atmospheric Drag Experiment campaign Report for the period 9 December 2012 to 5 January 2013 This reporting period covers four weeks of Venus Express operations, including the start of the fourteenth occultation season, end of the tenth Atmospheric Drag Experiment campaign, and pericentre altitude raising using four orbit correction manoeuvres.
- Cluster:Cluster hears the heartbeat of magnetic reconnection For the first time, scientists have resolved the detailed structure of the core region where magnetic reconnection takes place in the magnetosphere of Earth using unprecedented wave measurements. The study, based on data from ESA's Cluster mission, has mapped different types of electrostatic waves in this region. The waves trace populations of plasma particles that are involved in the different stages of a magnetic reconnection event.
- Rosetta:No. 158 - Spin-up and entry into deep-space hibernation Report for the period 6 to 14 June 2011This report covers nine days of Rosetta mission operations. The main activities were the spin-up of the spacecraft and entry into deep-space hibernation mode. The spacecraft will remain in this state until 20 January 2014 when the hibernation exit sequence will be initiated. The next Rosetta status report will be issued towards the end of January 2014.
