A long time ago… in galaxies far far away, the first stars were born in the early universe. But when and how? That’s a mystery Webb is one step closer to solving.
Using Webb, researchers have found two early galaxies that are unusually bright, one of which could contain the most distant starlight ever seen. The galaxies are thought to have existed 350 and 450 million years after the big bang (respectively, from top to bottom). Unlike our Milky Way, these first galaxies are small and compact, with spherical or disk shapes rather than grand spirals.
Webb’s new findings suggest that the galaxies would have had to begin coming together about 100 million years after the big bang — meaning that the first stars might have started forming in such galaxies around that time, much earlier than expected.
Follow-up observations with Webb’s spectrographs will confirm the distances of these primordial galaxies and help us learn more about the earliest stars. More: www.nasa.gov/feature/goddard/2022/nasa-s-webb-draws-back-...

[Image description: Countless glowing galaxies of all shapes and sizes speckling the black backdrop of space. Some are spiral, some more disk-shaped and others spherical. Farther galaxies are only seen as dots. Their colors include blue, pink, orange, and white. Towards the center left, a red dot of a galaxy, along with some surrounding streaks, are framed in a tiny white box. This box is attached to a close-up view in a much larger inset box. The red dot is a never-before-seen galaxy discovered by Webb, thought to have existed 350 million years after the big bang.

Reaching a major milestone, engineers have connected successfully the two halves of the NASA/ESA/CSA James Webb Space Telescope for the first time at Northrop Grumman’s facilities in Redondo Beach, California. Once it reaches space, Webb will explore the cosmos using infrared light, from planets and moons within our Solar System to the most ancient and distant galaxies.
To combine both halves of Webb, engineers carefully lifted the telescope (which includes the mirrors and science instruments) above the already-combined sunshield and spacecraft using a crane. Team members slowly guided the telescope into place, ensuring that all primary points of contact were perfectly aligned and seated properly. The observatory has been mechanically connected; next steps will be to electrically connect the halves, and then test the electrical connections.
Later, engineers will fully deploy the intricate five-layer sunshield, which is designed to keep Webb's mirrors and scientific instruments cold by blocking infrared light from Earth, the Moon and Sun. The ability of the sunshield to deploy to its correct shape is critical to mission success.
Webb is scheduled for launch on a European Ariane 5 rocket from French Guiana in March 2021.
The James Webb Space Telescope is an international project led by NASA with its partners, ESA and the Canadian Space Agency. As part of its contribution to the project, ESA provides the NIRSpec instrument, the Optical Bench Assembly of the MIRI instrument, the Ariane 5 launcher, and staff to support mission operations at the Space Telescope Science Institute (STScI) in Baltimore, USA.

In a survey of 100,000 galaxies (called Cosmic Evolution Early Release Science, or CEERS), Webb spotted the most distant active supermassive black hole to date, plus two more small early black holes and 11 early galaxies. All of these objects existed in the first 1.1 billion years after the big bang.

This image: Researchers have identified the most distant active supermassive black hole to date in the James Webb Space Telescope’s Cosmic Evolution Early Release Science (CEERS) Survey. The black hole, within galaxy CEERS 1019, existed just over 570 million years after the big bang and weighs only 9 million solar masses. For context, the black hole at the center of our Milky Way galaxy is 4.6 million times the mass of the Sun, and other very distant supermassive black holes we’ve known about for decades typically weigh more than 1 billion times the mass of the Sun.

Image description: A graphic titled “Cosmic Evolution Early Release Science (CEERS) Survey, Black Hole Existed 570 Million Years After Big Bang.” The graphic shows the redshift (how long ago the light was emitted) of one active supermassive black hole. At top right is a very small zoomed out version of the complete galaxy field. To its left is a zoomed-in area. It shows an assortment of galaxies, but has an inset box singling out 3 red dots, 2 with a green tint. This group is labeled CEERS 1019, 13.2 billion years. It shows a black hole from 13.2 billion years ago. The bottom shows a line graph with data from Webb’s NIRSpec. It plots wavelength of light in microns on the x-axis and relative brightness of light on the y-axis. Webb data is shown as an uneven white line and fitted to 2 different models. One is a smooth purple line with a large peak, representing slower gas in the galaxy. The other is a smooth yellow line with a small peak, representing faster gas around the black hole.

On Monday 20th July 2020, around 420 coaches descended on London and honked their horns from Earls Court, along the Chelsea Embankment, through Parliament Square and up to Tower Bridge. Their aim was to highlight to the Government the severe financial crisis the industry currently finds itself in with no prospect of any sort of recovery until at least next summer.
I witnessed the parade pass Chelsea Bridge with the lead vehicle passing at 11:00 and the final coach passing some 3 hours later!!
For this event I decided to focus on the coaches themselves.

This image: Researchers using data and images from the James Webb Space Telescope’s Cosmic Evolution Early Release Science (CEERS) Survey identified two supermassive black holes that are more similar in size to Sagittarius A*, the supermassive black hole at the center of our Milky Way galaxy’s center, than other extremely distant galaxies observed earlier by other telescopes. Webb’s spectra show that these black holes weigh only 10 million times the mass of the Sun. Other very distant supermassive black holes we’ve long known about are 1 billion times the mass of the Sun.

Webb continues on its path to becoming a focused observatory. The team has successfully worked through the second and third out of seven total phases of mirror alignment. With the completion of these phases, called Segment Alignment and Image Stacking, the team will now begin making smaller adjustments to the positions of Webb’s mirrors.
After moving what were 18 scattered dots of starlight into Webb’s signature hexagonal formation, the team refined each mirror segment’s image by making minor adjustments, while also changing the alignment of Webb’s secondary mirror. The completion of this process, known as Segment Alignment, was a key step prior to overlapping the light from all the mirrors so that they can work in unison.
Once Segment Alignment was achieved, the focused dots reflected by each mirror were then stacked on top of each other, delivering photons of light from each segment to the same location on NIRCam’s sensor. During this process, called Image Stacking, the team activated sets of six mirrors at a time and commanded them to repoint their light to overlap, until all dots of starlight overlapped with each other.
In this image: This hexagonal image array captured by the NIRCam instrument shows the progress made during the Segment Alignment phase, further aligning Webb’s 18 primary mirror segments and secondary mirror using precise movements commanded from the ground.

NASA's James Webb Space Telescope needed a primary mirror so large it couldn’t fit in an existing rocket, so the team took a lesson from honeybees. Their efficient honeycomb pattern used inside beehives allows each mirror to perfectly fit together at their edges, effectively creating a singular and massively powerful unit. The 18 hexagonal mirror segments are able to fold to fit inside the rocket fairing.
Each gold-plated hexagon is equipped with a set of actuators, which are small devices that allow for impressively accurate fine-tuning of their position, angle and even curvature. If adjustments need to be made, they can be precisely applied to each, without disturbing the others while in space.

In this photo, engineers and technicians are installing flight thermal blankets on the structure that supports the James Webb Space Telescope's secondary mirror in a clean room at Northrop Grumman, Redondo Beach, California. The strings, which are shown hanging down from the strut in this image, are called lacing cords, and they are used to tie the blankets to the struts. Why are the blankets tied on with lacing cords? Tying the blankets on allows them to be securely attached, while allowing enough room for them to shrink and move as Webb goes through the movements and temperature changes that will occur during its trip from Earth to its home in space, a million miles away. This technique also makes certain that the blankets are secure without using exposed adhesive for attaching the blankets. It’s cleaner for the telescope optics to not use a sticky adhesive nearby their pristine surfaces.
Because the blankets are tied (and also sewn on), team members working on the thermal blankets are one of the most unique groups of people working on Webb. They often have backgrounds that have included tailoring and costume making, prior to work in the aerospace industry.

The Waste Management Phoenix Open
Scottsdale, Arizona
Webb won the 2020 Phoenix Open on Super Bowl Sunday after beating Tony Finau in a one-hole playoff.
Despite the fact that the tournament competes for the attention of fans with the Super Bowl on its final day, it consistently has, by far, the largest galleries in golf. Attendance for the week consistently tops 500,000 with 200,000 on the course on Saturday.
The Phoenix Open was first played in 1932 and moved to the Tournament Players Club Scottsdale in 1987 where the facilities can accommodate large galleries. It is the most attended of all golf tournaments. Record attendance was set last year (2018) when 720,000 attended for the week. The 16th hole has become the first hole in golf to be completely enclosed by sponsor boxes and bleachers and is known as the noisiest hole in golf. Even though it is a short par 3, it intimidates the best of players.
The tournament is sponsored by the Thunderbirds who do a remarkable job preparing the facility and have contributed more than $100 million to various charities within Arizona.

Showbus, Woburn Abbey, 20 September 2015
New to Kings, Middlesbrough
The cause of the chaos that will go down in Showbus history. Thanks to poor directions by the marshals, the coach got bogged down with its back end blocking the only access road at the entrance so the entire site became inaccessible. It took well over an hour to free it, including bringing in a recovery vehicle that itself got stuck, during which time a two-mile tailback developed down the abbey driveway and back into Woburn village.
This “selfie” taken by Webb of its primary mirror was not captured by an externally mounted engineering camera, but with a special lens within its Near Infrared Camera (NIRCam). This special lens is meant for engineering, not science, and allows NIRCam to capture an “inward-looking” image of the primary mirror. This image helps us to check that the telescope is aligned with the science instruments.
What you are seeing in this image is the actual primary mirror of Webb as it observes its engineering target, a bright star. All the mirror segments are seeing starlight, but the bright segment is bright because, from NIRCam’s view, the segment is directly aligned with the star.
