Washington (AFP) - Get ready for a summer blockbuster. The James Webb Space Telescope will produce "spectacular color images" of the cosmos in mid-July -- its first observations dedicated to its mission of scientific discovery, an astronomer overseeing the project said Monday. The successor to Hubble has spent the last five months aligning its instruments in preparation for the big reveal, with scientists deliberately remaining coy about where the cameras will be pointed. "We'd really like it to be a surprise," Klaus Pontoppidan, a scientist at the Space Telescope Science Institute in Baltimor...

Washington (AFP) - The James Webb Space Telescope has arrived at its cosmic parking spot a million miles away, bringing it a step closer to its mission to unravel the mysteries of the Universe, NASA said Monday. At around 2:00 pm Eastern Time (1900 GMT), the observatory fired its thrusters for five minutes to reach the so-called second Lagrange point, or L2, where it will have access to nearly half the sky at any given moment. The delicate burn added 3.6 miles per hour (1.6 meters per second) to Webb's overall speed, just enough to bring it into a "halo" orbit around L2, 1.5 million kilometers...

Washington (AFP) - The most powerful space telescope ever built completed a tricky two-week-long deployment phase Saturday, unfolding its final golden mirror panel, as it readies to study every phase of cosmic history. Engineering teams in the James Webb Space Telescope's control room cheered as confirmation came back that its final wing was deployed and latched into place. "I'm emotional about it -- what an amazing milestone," Thomas Zurbuchen, a senior NASA engineer, said during the live video feed as stargazers worldwide celebrated. Because the telescope was too large to fit into a rocket's...

Washington (AFP) - The James Webb Space Telescope fully deployed its tennis-court sized sunshield Tuesday, a critical milestone for the success of its mission to study every phase of cosmic history, NASA said. "All five layers of the sunshield are fully tensioned," said an announcer at the observatory's control center in Baltimore, where team members cheered, a live feed showed. The 70-foot (21 meter) long, kite-shaped apparatus acts like a parasol, ensuring Webb's instruments are kept in the shade so they can detect faint infrared signals from the far reaches of the Universe. Each of the laye...

Washington (AFP) - The James Webb Space Telescope fully deployed its five-layer sunshield Tuesday, a critical milestone for the success of its mission to study every phase of cosmic history, US space agency NASA said. "All five layers of the sunshield are fully tensioned," said an announcer at the telescope's control center in Baltimore, where team members cheered, a live feed showed. The tennis court size, kite-shaped apparatus acts like a parasol, ensuring the observatory is kept in the shade so that it is able to detect faint infrared signals from the far reaches of the Universe.

Kourou (AFP) - The world's most powerful space telescope on Saturday blasted off into orbit, headed to an outpost 1.5 million kilometres (930,000 miles) from Earth, after several delays caused by technical hitches. The James Webb Space Telescope, some three decades and billions of dollars in the making, left Earth enclosed in its Ariane 5 rocket from Kourou Space Centre in French Guiana. "What an amazing day. It's truly Christmas," said Thomas Zurbuchen, head of scientific missions for NASA, which together with the European and Canadian space agencies, ESA and ACS, built the telescope. ESA ch...

Kourou (AFP) - The world's most powerful space telescope on Saturday blasted off into orbit, headed to an outpost 1.5 million kilometres (930,000 miles) from Earth, after several delays caused by technical hitches. The James Webb Space Telescope, some three decades and billions of dollars in the making, left Earth enclosed in its Ariane 5 rocket from Kourou Space Centre in French Guiana. It is expected to take a month to reach its remote destination. It is expected to beam back new clues that will help scientists understand more about the origins of the Universe and Earth-like planets beyond o...

Washington (AFP) - The launch of the James Webb Space Telescope, which astronomers hope will herald a new era of discovery, was again pushed back Tuesday until at least Christmas Day due to "adverse weather conditions" at the launch site in French Guiana, NASA said. The new target date, if determined to be viable, would be an actual Christmas gift for scientists who have been waiting three decades to see the largest and most powerful telescope take off for space aboard an Ariane 5 rocket. The launch window on Saturday is from 1220-1252 GMT, the US space agency said. "Tomorrow evening, another ...

Washington (AFP) - The launch of the James Webb Space Telescope, which astronomers hope will herald a new era of discovery, has been delayed until December 22 after an accident at its launch facility in French Guiana, NASA said Monday. Technicians were preparing to attach the $10 billion observatory to a launch vehicle adapter, used to fix it to the upper stage of an Ariane 5 rocket. "A sudden, unplanned release of a clamp band – which secures Webb to the launch vehicle adapter – caused a vibration throughout the observatory," the US space agency said in a blog post, adding that the incident o...
