Webb telescope's first full color, scientific images coming in July
Monday, 09 May 2022 16:40 Write a comment
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 Baltimore told reporters, adding that the secrecy was partly due to the first targets not yet being finalized.
NASA and its partners the European Space Agency (ESA) and Canadian Space Agency (CSA) formed a committee to create a ranked list of objects, which they now intend to work through.

The James Webb Space Telescope is aligned across all four of its science instruments, as seen in a previous engineering image showing the observatory’s full field of view. Now, we take a closer look at that same image, focusing on Webb’s coldest instrument: the Mid-Infrared Instrument, or MIRI.
The MIRI test image (at 7.7 microns) shows part of the Large Magellanic Cloud. This small satellite galaxy of the Milky Way provided a dense star field to test Webb’s performance.
Here, a close-up of the MIRI image is compared

What does micrometeoroid damage do to gossamer structures like Webb's sunshield?
Monday, 09 May 2022 13:23 Write a comment
Tiny little bullets flood the solar system, each micrometeoroid a potential hazard. New research has found that the James Webb Space Telescope's thin sunshields, and future inflatable spacecraft, may be at risk.
A micrometeoroid is a tiny bit of space junk usually weighing less than a gram. Some of them are the leftover bits of the countless collisions that have occurred over the past 4.5 billion years of the history of the solar system. Most, however, come from the dust cloud that initially collapsed to form our solar system, and never got to be a part of a larger body.

As Artemis sets its sights on the Moon, powered by the European Service Module (ESM), all eyes will again turn to the night sky. This interactive publication encourages us to look up at our natural satellite and think about how the Moon has inspired us, from Ancient Greece to the 21st century, to develop our understanding of astronomy, physics and our place in the Solar System.
