NASA Explains Why James Webb Space Telescope Uses ‘Salty’ Lenses

As NASA completes all major deployments of the James Webb Space Telescope and the observatory enters a “cooling” period, the agency is sharing some interesting facts about the $10-billion (roughly Rs. 74,100 core) observatory. These include some lenses which are made out of salt. But why does this infrared telescope need a “salty” lens? In […]

James Webb Space Telescope Entering ‘Period of Cooldown’: Details

James Webb Space Telescope scientists said they have completed all major structural deployments of the $10-billion (roughly Rs. 74,000 crore) observatory in space. What now starts is the primary mission of the telescope, they added. James Webb Space Telescope was launched aboard an Ariane 5 rocket on December 25. It is so big that it […]

James Webb Telescope Main Mirror to Be Deployed Tomorrow: How to Watch Live

Through the past week, NASA engineers have been working diligently to deploy major equipment and tools aboard James Webb Space Telescope (JWST), including its sunshield and secondary mirror. On Saturday, January 8,  the primary camera of the $10-billion (roughly Rs. 74,340 crore) space observatory will be deployed, which will study the origin of the Universe […]

James Webb Space Telescope Successfully Deploys Secondary Mirror

James Webb Space Telescope, a day after fully tensioning the sunshield, has now completed another complex procedure. The space observatory’s secondary mirror was deployed using what a Webb engineer described as the “world’s most sophisticated tripod.” The 2.4-feet-wide mirror is located on the tips of three carbon fibre tubes which extend out from the large […]

James Webb Space Telescope Fully Deploys Sunshield

James Webb Space Telescope has completed the complex process of deploying its kite-shaped sunshield. The sunshield, about the size of a tennis court, has five layers. The first three were deployed initially and the last two were done late last night. Deploying all five layers was crucial for the $10-billion (roughly Rs. 74,525 crore) space […]

James Webb Telescope Completes Deployment of First 3 Layers of Sunshield

NASA engineers have begun a crucial phase in deploying the James Webb Space Telescope. The engineers have started to tighten the tension in its tennis court-sized sunshield. The stretching of the first three layers of the five-layer sunshield was successful and the final two layers will be deployed today, January 4, the space agency said. […]

James Webb Telescope Attempts to Unpack Sun Shield: Latest Updates

NASA’s James Webb Telescope is going through some critical manoeuvre phases which will determine its success as a mission to shed light on the origin of the universe. The powerful space observatory, which was launched into orbit on Christmas Day, is heading for a “make or break” moment when it attempts to unpack its five-layered […]

James Webb Space Telescope Carries Out Time-Critical Mid-Course Correction

NASA’s James Webb Space Telescope, which was launched on Christmas Day, had begun its first mid-course correction burn on December 25 at 7:50pm EST (6.20am IST on December 26). This burn is one of two time-sensitive milestones, the first being the deployment of solar arrays which occurred shortly after its launch. The burn, which lasted […]

James Webb Space Telescope Launch Delayed by NASA to Christmas Day

NASA has delayed the launch of the James Webb Space Telescope, which would be the successor to the Hubble. The space agency said the launch will happen a day later than the earlier stipulated time, on Christmas Day, December 25, from the Kourou spaceport in French Guiana, where high winds are a major factor. An […]

Hubble Captures Stunning Image of Colliding Gases in ‘Running Man’ Nebula

Hubble Space Telescope has often captured stunning images of mysterious events in space. It has allowed astronomers to widen their research and uncover new details. Recently, the telescope was trying to understand how young stars influenced their environment and it witnessed a shock wave of colliding luminous gases in the ‘Running Man’ Nebula. The image […]
