25 October 2019: We are excited to announce the sixth conference in the series Science with the Hubble and James Webb Space Telescopes — Entering a golden age for UV - Optical - IR astronomy, sponsored by ESA in collaboration with the University of Stockholm. It will be held in Stockholm, at the Hotel Hasselbacken, between 30 March and 3 April 2020. Next April, we will celebrate Hubble’s 30 splendid years of scientific contributions to all branches of astronomy. At the same time, the countdown is accelerating towards the launch of the James Webb Space Telescope, planned for March 2021. Webb’s unique combination of sensitivity, near- and mid-infrared wavelength coverage and spatial resolution promises to revolutionise our view of the Universe. Working in synergy, these two observatories will push the boundaries of knowledge against the backdrop of a rapidly evolving astronomical landscape. In space, GAIA will soon have completed its nominal high-precision astrometric …

15 October 2019: To celebrate the NASA/ESA Hubble Space Telescope’s 30 incredible years in orbit, ESA/Hubble will deliver high-quality large-format prints of Hubble’s anniversary image for display at informal education venues across Europe.

In order to submit an application, the applicant (on behalf of the associated institution) must agree to the following terms in respect of the Hubble 30th anniversary image unveiling: Hold an image unveiling event in celebration of Hubble’s 30th anniversary in orbit on or after the date and time we provide. We also welcome proposals for creative electronic image unveilings. Ensure a strong media presence at the event and encourage press coverage, including social media coverage. The event must be free and open to the public. Engage with social media by tweeting or uploading pictures of your event on Facebook. Identify a long-term plan for displaying the Hubble anniversary image (e.g., …

30 September 2019: In April 2020 the NASA/ESA Hubble Space Telescope will celebrate 30 years since its launch. Hubble has delved deeper into the early years of the Universe than was ever thought possible, played a critical part in the discovery that the expansion of the Universe is accelerating and probed the atmospheres of planets around distant stars. It has transformed the way the public sees the universe by presenting breathtaking and profound images of newborn stars to the oldest known galaxies. To celebrate these three decades of success in science, engineering and culture, ESA/Hubble will present a series of initiatives to involve the public in the celebrations. The first of these is a social media competition that will explore hidden gems from the ESA/Hubble image archive. These are images that are not as well known as the Top 100 Images, but are also truly beautiful. From 30 September to 10 November 2019, …

24 September 2019: ESA/Hubble is pleased to announce the release of the Hubble Catalog of Variables, the first full, homogeneous catalogue of variable sources based on archival HST data. The HCV was developed over four years by a team of astronomers at the National Observatory of Athens, led by Alceste Bonanos and sponsored by ESA in collaboration with STScI. The HCV is now available to the community via the ESA Hubble Science Archive (eHST) at ESAC and MAST at STScI, and can easily be explored using the HCV Explorer, a visualisation tool developed at ESAC specifically to navigate the HCV and look up your favorite object(s) or field(s)! Despite not being a survey telescope, the Hubble Space Telescope (HST) has obtained multi-epoch observations under multiple, diverse observing programmes. This provides the opportunity for a comprehensive variability search that aims to uncover new variables over a range of magnitudes that is difficult to reach …

24 June 2019: Every year on 30 June, the global “Asteroid Day” event takes place to raise awareness about asteroids and what can be done to protect Earth from possible impact. The day falls on the anniversary of the Tunguska event that took place on 30 June 1908, the most harmful known asteroid related event in recent history. This week, a team of astronomers, planetary scientists and software engineers based at ESA and other research institutes has launched a new citizen science project: the Hubble Asteroid Hunter. The project was developed as part of the Zooniverse – the world’s largest and most popular platform for people-powered research. The new project features a collection of archival Hubble images where calculations indicate that an asteroid might have been crossing the field of view at the time of the observation. Everyone can participate! By identifying the asteroids potentially present in these images and marking the exact …

12 June 2019: Transits — an object moving between the parent star and the observing telescope — not only allow to detect exoplanets orbiting distant stars, but also to infer many of their properties. This Hubblecast explores what we can learn from these transits, what Hubble has done in this field and what we can expect to learn through the upcoming NASA/ESA/CSA James Webb Space Telescope.

29 April 2019: The Space Telescope Science Institute (STScI) has announced a Call for Applications to attend the James Webb Space Telescope (JWST) Master Class. The class will provide dedicated JWST proposal training to selected researchers who are willing to share their knowledge with scientists at their local/regional institutions. The original announcement from STScI can be found here. The European Space Agency (ESA) will provide a similar opportunity to European astronomers. A similar JWST Master Class will be organised at the European Space Astronomy Centre (ESAC) in the first week of February 2020. The workshop will last approximately 2–3 days and will include topics related to JWST proposal planning, user tools, instrument modes, science cases, documentation, resources, and guidance regarding the education and dissemination of these topics to others. Approximately 10 astronomers will be selected to participate in the European JWST Master Class. These Master Class graduates will host one proposal-preparation training activity/mini-workshop …

18 April 2019: On 18 April 2019 Hubble is celebrating its 29th year in space. For this anniversary NASA and ESA dedicated a small amount of its precious observation time to take a look at the beautiful Southern Crab Nebula. This beautiful nebula is created by the ejected material of a red giant, which is in close interaction with a white dwarf star.

8 April 2019: For 29 years, the NASA/ESA Hubble Space Telescope has been expanding our cosmic horizons. Not only has Hubble revealed and shared the beauty, wonder, and complexity of the Universe, but it has also brought astronomy into the public eye, greatly impacting our culture, society, and art. On 8 April 2019, the Our Place In Space exhibition premiered in Las Cruces exhibition at the Mesilla Valley Mall, led by ESA Hubble Space Telscope Project Scientist Antonella Nota. Developed in partnership with in partnership with the Space Telescope Science Institute and the European Space Agency, this is the first time that Our Place In Space has been hosted in the United States. This art exhibition features large images from the Hubble Telescope that are on display at eight locations around the city, alongside pieces created by local artists. By seamlessly integrating perspectives from both artists and astronomers, Our Place in Space inspires …

3 April 2019: Right after the Universe started with the Big Bang, the cosmos was dark. Only the first stars created millions of years later brought light. These first stars and their radiation drastically changed the Universe during what is known as the epoch of reionisation. This Hubblecasts talks about this important time, what Hubble has shown us so far, the open questions and what we can expect from future missions.

20 February 2019: Born in 1868, Henrietta Leavitt was an astronomer ahead of her time, whose work helped to revolutionise our understanding of the Universe. While working at Harvard Observatory, she began to study stars of fluctuating brightness. She made a crucial observation about these objects, which gave astronomers a new way to measure distances, ultimately leading to such impactful discoveries as the expansion of the Universe. This new Hubblecast episode explores the life of Henrietta Leavitt and how her work enabled the discoveries of Edwin Hubble.
