Replay of the 16 December 2021 online press briefing about the James Webb Space Telescope.


-          Günther Hasinger, ESA Director of Science

-          Daniel Neuenschwander, ESA Director of Space Transportations

-          Thomas Zurbuchen, NASA’s Associate Administrator for science

-          Antonella Nota, ESA Webb Project Scientist

-          Gillian Wright, European Principal Investigator for the MIRI instrument

Developed and constructed over more than 30 years, Webb is a remarkable feat of engineering and technology – with the largest astronomical mirror ever flown in space, sophisticated new scientific instruments, and a sunshield the size of a tennis court.

Webb is designed to answer outstanding questions about the Universe and to make breakthrough discoveries in all fields of astronomy.

The major contributions of ESA to the mission are: the NIRSpec instrument; the MIRI instrument optical bench assembly; the provision of the launch services; and personnel to support mission operations. In return for these contributions, European scientists will get a minimum share of 15% of the total observing time, like for Hubble.

Webb’s partners are ESA, NASA and the Canadian Space Agency (CSA).

      One of the first observations made by NASA’s James Webb Telescope shows a Wolf-Rayet star, named WR 124. The rare sight of a Wolf-Rayet star – among the most luminous, most massive, and most briefly detectable stars known – was one of the first observations made by NASA’s James Webb Space Telescope in June 2022. Webb shows the star, WR 124, in unprecedented detail with its powerful infrared instruments. The star is 15,000 light-years away in the constellation Sagittarius. 

      But the James Webb Space Telescope has not only captured a remarkable image of the star WR 124, as the same image also shows a mysterious luminous object in space at a considerable distance of the star WR 124. 

      A closer look reveals that the enormous object resembles what looks like an alien craft in the form of a flying saucer with a rectangular porthole at the front of the craft. Furthermore it looks like there is some kind of rectangular platform underneath the UFO that may have been attached to the craft.  

      Another detail is the object's unique shape which is symmetrical, (see image below) making it more likely that JWST captured an alien spacecraft rather than a celestial body.

      A Wolf-Rayet star is a rare prelude to the famous final act of a massive star: the supernova. As one of its first observations in 2022, the NASA/ESA/CSA James Webb Space Telescope captured the Wolf-Rayet star WR 124 in unprecedented detail.

      A previously unknown 100–200-metre asteroid — roughly the size of Rome’s Colosseum — has been detected by an international team of European astronomers using the NASA/ESA/CSA James Webb Space Telescope. Their project used data from the calibration of the Mid-InfraRed Instrument (MIRI), in which the team serendipitously detected an interloping asteroid. The object is likely the smallest observed to date by Webb and may be an example of an object measuring under 1 kilometer in length within the main asteroid belt, located between Mars and Jupiter. More observations are needed to better characterize this object’s nature and properties.
