19/12/2016 Happy 3rd birthday to Gaia!

Since the launch of Gaia on 19 December 2013 Gaia performed an impressive number of astrometric, photometric and spectroscopic measurements. More than 60 billion times an object moved through the Gaia focal plane. The total amount of science data collected since launch can now be viewed through a new information page on mission status numbers.

01/12/2016 Vacancy: PhD positions at the Institute of Cosmic Science (Barcelona)

The Institute of Cosmic Science at University of Barcelona has proposed several PhD positions within the INPhINIT, "la Caixa" Foundation Fellowship Programme. Among all the available projects, the ones that are most strongly related with Gaia are: Detection Classification for Gaia, Gaia Alerts follow-up from Montsec Observatory, Open Clusters Studies in the Gaia era, and Gaia Detection of Ultra Faint Dwarf Galaxies in the halo as probes for cosmological models.

There are some requirements on the amount of time you spent in Spain in the past three years. You can find more information through here.

01/12/2016 Vacancy: Tenured lectureship in astro-statistics

The Institute of Astronomy in Cambridge has a vacancy for a tenured lectureship in astro-statistics. The deadline for applications is 7 December 2016. This position will include work on large astronomical surveys like SDSS, Gaia, LSST, RAVE & APOGEE. More information can be found on the AAS website.

18/11/2016 Gaia16aye is getting brighter

The spectacular binary microlensing event, Gaia16aye, is getting brighter just as predicted in the Image of the Week item of 27 October. The peak of the brightening is expected on 21 or 22 November and should reach about 11 magnitude in l-band. We are very lucky as the next observation of this target by Gaia happens to be right in time for this brightening and will happen on 21 November (as predicted using GOST).

An extensive follow-up campaign is conducted, according to Lukasz Wyrzykowski. You can contact him if you would like to be involved or if you want to share some data with him on this expected brightening.  The current model, including astrometric prediction, is available here.

18/11/2016 Gaia 'Ask Me Anything' on Gaia Operations

On 21 November 16:00 CET, ESOC will conduct a live 'Ask Me Anything' text chat via Reddit, focusing on Gaia operations. You can find more information on how to participate through this link. This AMA session will highlight day-to-day operations performed for Gaia. If you ever wanted to know more about how well the spacecraft is performing, how commands are sent up to the satellite or what the orbit of Gaia looks like, this is the moment to ask. Our operations team will be happy to answer your questions.

24/08/2016 A Very Human Venture: Personal Perspectives on Gaia's Data Processing and Analysis Consortium

Since its launch in December 2013 Gaia has been sweeping the skies mapping around one billion stars. The data collected will allow astronomers to probe the very nature of the astronomical objects observed by the spacecraft. But before the data can be useful to the scientific community they must pass through a complex and robust processing pipeline. This is the story of how that pipeline was created and how it has struggled and thrived by virtue of being a truly human endeavour. To read the whole piece, click here.

16/08/2016 Gaia's second anniversary marked by successes and challenges

Operating in the depths of space, far beyond the Moon's orbit, ESA's Gaia spacecraft has now completed two years of a planned five-year survey of the sky. Despite a series of unexpected technical challenges, the mission is on track to complete the most detailed and complex mapping of the heavens ever undertaken. The first mission data will be released on 14 September 2016. Read the whole story here.

18/07/2016 Register for the Gaia 2016 Data Release #1 Workshop now

The Gaia 2016 Data Release #1 Workshop, jointly organised by ESA and DPAC, will present the Gaia mission, its data and its usage. Plenary sessions providing general information will be complemented by smaller parallel hands-on sessions and open forums to discuss own projects, results and foster collaboration.

14/07/2016 A gift from Gaia to Pluto observers on the 1st anniversary of a historic flyby

It is just a star out of a billion, but it happens to hide behind Pluto on 19 July 2016. The improved Gaia stellar positions in Gaia DR1 (to be released on 14 September 2016) will be useful for occultation observations. With Pluto these are of particular interest as the details of the fading, when Pluto moves in front of the star, will reveal details about the atmosphere and its possible changes since the flyby of the New Horizons mission 1 year ago (14 July 2015). Observers exactly aligned with the centre of Pluto and the star could record an ephemeral brightness increase due to light focused by the atmosphere of the dwarf planet as if it was a lens. This "central flash", showing up only for a few seconds, provides the most detailed information possible from remote observations, but also requires to accurately know the position of the star and of Pluto. The Gaia position for UCAC4 345-180315 at epoch 2015.0 in the J2000 system is Right Ascension 286.8421576 degrees and Declination -21.1745647 degrees (19h7m22.1178s -21d10’28.433”). With Gaia's position accuracy, which is 1 milliarcsec for this star at epoch 2015.0, the biggest uncertainty of the timing and location of the event as observed from the Earth will be due to uncertainty of the precise Pluto orbit. That too will be tackled by Gaia and published in future data releases.

04/07/2016 Mark your calendar: Gaia data release set for 14 September

The first Gaia data release will be online on 14 September. It will include the positions and G magnitude for about one billion stars using observations taken between 25 July 2014 and 16 September 2015. In addition, for a subset of data – about 2 million stars in common between the Tycho-2 Catalogue and Gaia – there will be a five-parameter astrometric solution (TGAS), giving the positions, parallaxes, and proper motions for those objects. Photometric data for RR Lyrae and Cepheid variable stars that were observed frequently during a special scanning mode that repeatedly covered the ecliptic poles will also be made public. Further details are available on the release pages. Read the whole story here.

09/02/2016 The first Gaia intermediate data release

The Gaia Science Team and Data Processing Consortium Executive had a joint meeting to evaluate the progress in data processing toward the first data release (Gaia-DR1). Some delays and a few late calibration improvements lead to the completion of data processing by the end of March. Although the data quality looks very good, it was jointly decided not to make any compromises in the validation activities starting at the beginning of April. The current schedule anticipates the release of Gaia-DR1 toward the end of summer 2016.

06/01/2016 Vacancy: 2016 ESAC Gaia trainee project

ESA is offering a Gaia trainee project opportunity at ESAC in 2016. The main objective of the traineeship is to apply 2D PSF deconvolution techniques to retrieve all the astrometric information stored in SM SIF images. General purpose tools such as Daophot or Sextractor will be used in the beginning, with the goal of doing some exploratory steps toward developing ad-hoc tools using Gaia calibrated PSF models. Detailed information about the project can be found on the ESAC trainees page. The deadline for applications is 12 January 2016.
