Pillars of Creation (NIRCam and MIRI composite image)

By combining images of the iconic Pillars of Creation from two cameras aboard the NASA/ESA/CSA James Webb Space Telescope, the Universe has been framed in its infrared glory. Webb’s near-infrared image was fused with its mid-infrared image, setting this star-forming region ablaze with new details.

Myriad stars are spread throughout the scene. The stars primarily show up in near-infrared light, marking a contribution of Webb’s Near-Infrared Camera (NIRCam). Near-infrared light also reveals thousands of newly formed stars – look for bright orange spheres that lie just outside the dusty pillars.

In mid-infrared light, the dust is on full display. The contributions from Webb’s Mid-Infrared Instrument (MIRI) are most apparent in the layers of diffuse, orange dust that drape the top of the image, relaxing into a V. The densest regions of dust are cast in deep indigo hues, obscuring our view of the activities inside the dense pillars.

Dust also makes up the spire-like pillars that extend from the bottom left to the top right. This is one of the reasons why the region is overflowing with stars – dust is a major ingredient of star formation. When knots of gas and dust with sufficient mass form in the pillars, they begin to collapse under their own gravitational attraction, slowly heat up, and eventually form new stars. Newly formed stars are especially apparent at the edges of the top two pillars – they are practically bursting onto the scene.

At the top edge of the second pillar, undulating detail in red hints at even more embedded stars. These are even younger, and are quite active as they form. The lava-like regions capture their periodic ejections. As stars form, they periodically send out supersonic jets that can interact within clouds of material, like these thick pillars of gas and dust. These young stars are estimated to be only a few hundred thousand years old, and will continue to form for millions of years.

Almost everything you see in this scene is local. The distant universe is largely blocked from our view both by the interstellar medium, which is made up of sparse gas and dust located between the stars, and a thick dust lane in our Milky Way galaxy. As a result, the stars take center stage in Webb’s view of the Pillars of Creation.

The Pillars of Creation is a small region within the vast Eagle Nebula, which lies 6,500 light-years away.

Revisit Webb’s near-infrared image and its its mid-infrared image. The Pillars of Creation was made famous by the NASA/ESA Hubble Space Telescope in 1995, and again in 2014.

MIRI was contributed by ESA and NASA, with the instrument designed and built by a consortium of nationally funded European Institutes (The MIRI European Consortium) in partnership with JPL and the University of Arizona.

Webb’s NIRCam was built by a team at the University of Arizona and Lockheed Martin’s Advanced Technology Center.

European Service Module, Orion, Moon, Earth

View of ESA’s European Service Module that is powering NASA’s Orion spacecraft, pointing at our planet and the Moon, taken on the 13th day of flight for the Artemis I mission at 22:06 CET (21:06 GMT), 28 November 2022. It shows Orion and the European Service Module halfway through the Artemis I mission near its maximum distance from Earth, at 432210 km from our home planet and over 64 000 km from the Moon. Seen from the spacecraft our planet had just passed behind the Moon when this photo was taken, as Orion was in lunar orbit.

This picture was presented to French President Emmanuel Macron during his visit to NASA’s headquarters in Washington D.C., USA, on 30 November.

Cameras placed at the end of Orion’s four European-built solar array wings are recording the Artemis mission as engineers test the uncrewed Orion spacecraft’s capabilities, preparing for missions with astronauts to the Moon.

After its launch on November 16, Orion has circled the Moon on its 25-day Artemis I mission. Orion was launched by the NASA Space Launch System rocket at 7:47 CET (06:47 GMT) from launchpad 39B at NASA’s Kennedy Space Center in Florida, USA.ac

The European Service Module is powering Orion, providing propulsion, temperature control, electricity as well as storage and delivery for essential supplies such as fuel, water and air. The uncrewed mission to learn as much as possible about Orion and its European Service Module’s performance. The primary objectives are to demonstrate Orion’s heat shield on reentry, demonstrate operations and facilities during all mission phases, and retrieve the spacecraft after splashdown.

MTG-I1 meets its launch adapter

MTG-I1 meets its launch adapter

The first Meteosat Third Generation Imager (MTG-I1) satellite being fitted to the Ariane 5 launch adapter in preparation for liftoff in mid-December 2022. The satellite has been at Europe’s Spaceport in French Guiana since the middle of October being readied for liftoff. The image shows the satellite being fitted to the Ariane 5 launch adapter.

This new satellite carries two completely new instrument that will deliver high-quality data to improve weather forecasts: a Flexible Combined Imager and Europe’s first Lightning Imager.

The Flexible Combined Imager has more spectral channels and is capable of imaging in higher resolution compared to current Meteosat Second Generation’s Spinning Enhanced Visible and Infrared instrument.

The Lightning Imager offers a completely new capability for European meteorological satellites. It will continuously monitor more than 80% of the Earth disc for lightning discharges, taking place either between clouds or between clouds and the ground.

The full MTG system will span more than 20 years and hence comprises six satellites, four MTG-I and two sounding satellites, MTG-S.

Joining @NASA’s Orion spacecraft on the powerful Space Launch System rocket are ten CubeSats that will help prepare for the return of astronauts to our lunar companion. Our deep space antennas, along with the Goonhilly Earth Station in the UK, are tracking six of the small satellites, ensuring they arrive where they need to be, and their data gets back home.
