James Webb Space Telescope about to attempt next crucial step

It’s been a low-key week for the James Webb Space Telescope. Having successfully deployed its enormous sunshield earlier this month, followed a short while later by its golden primary mirror, the most advanced space telescope ever built has been quietly zipping through space toward its destination orbit almost a million miles from Earth.

After launching on December 25, the James Webb Space Telescope was 865,000 miles from Earth on Thursday — just 32,000 miles short of its destination orbit around the second sun-Earth Lagrange point, known as L2.

Webb is now gearing up for its next crucial step: A crucial burn to insert it into the L2 orbit, currently set for Monday, January 24.

The team confirmed the timing of the insertion maneuver in a tweet.

“Our orbital burn is now targeted for Monday afternoon to give our team time for the multiple hours of preparation required,” the message said.

Tracking our journey on Our orbital burn is now targeted for Monday afternoon to give our team time for the multiple hours of preparation required. Our milestones are human-controlled to provide our team flexibility to pause & adjust. #UnfoldTheUniverse

Since the successful deployment of the primary mirror a couple of weeks ago, the space telescope and its instruments have been gradually cooling down, a process aided by the tennis court-sized sunshield.

Before Webb can begin its work exploring deep space, the team has to work on aligning the telescope’s optics and calibrating the scientific instruments, a process expected to take about five months.

It means that Webb will start peering into deep space around June, observing the universe’s first galaxies, revealing the birth of stars and planets, and searching for exoplanets with the potential for sustaining life.

The James Webb Space Telescope is following in the footsteps of the Hubble Space Telescope, which has been exploring deep space for more than 30 years. But with Webb far more powerful than Hubble, scientists are hoping to make significant discoveries during the mission that go well beyond Hubble’s achievements.

The $10 billion mission — a partnership between NASA, the European Space Agency, and the Canadian Space Agency — launched on December 25 and will run for at least five years, though likely much longer.

James Webb captures a gorgeous stellar nursery in nearby dwarf galaxy
This new infrared image of NGC 346 from NASA’s James Webb Space Telescope’s Mid-Infrared Instrument (MIRI) traces emission from cool gas and dust. In this image blue represents silicates and sooty chemical molecules known as polycyclic aromatic hydrocarbons, or PAHs. More diffuse red emission shines from warm dust heated by the brightest and most massive stars in the heart of the region. Bright patches and filaments mark areas with abundant numbers of protostars. This image includes 7.7-micron light shown in blue, 10 microns in cyan, 11.3 microns in green, 15 microns in yellow, and 21 microns in red (770W, 1000W, 1130W, 1500W, and 2100W filters, respectively).

A gorgeous new image from the James Webb Space Telescope shows a stunning sight from one of our galactic neighbors. The image shows a region of star formation called NGC 346, where new stars are being born. It's located in the Small Magellanic Cloud, a dwarf galaxy that is a satellite galaxy to the Milky Way.

The star-forming region of the Small Magellanic Cloud (SMC) was previously imaged by the Hubble Space Telescope in 2005, but this new image gives a different view as it is taken in the infrared wavelength by Webb instead of the optical light wavelength used by Hubble.

Zoom into an incredibly detailed James Webb image of the Orion nebula
A short-wavelength NIRCam mosaic of the inner Orion Nebula and Trapezium Cluster.

A new image from the James Webb Space Telescope shows the majesty of the gorgeous Orion nebula in tremendous detail. The European Space Agency (ESA) has shared an extremely high-resolution version of the image that you can zoom into to see the details of this stunning cloud of dust and gas which hosts sites of star formation where new stars are being born.

The full image is available to view in the ESASky application, where you can zoom in a compare images of the same target taken in different wavelengths. There's also a very large version of the image if you want to download and pursue it at your leisure.
