The James Webb Space Telescope will zero in on a portion of the famous Orion Nebula, the closest region of mass star-formation to Earth, to learn more about how massive young stars shape their environments. The Orion Nebula, some 1,350 light-years away from Earth, is known as a stellar nursery. Dense clouds of gas and dust … Read more
Stars are getting sharper in the James Webb Space Telescope‘s field of view. The team recently completed the third of seven planned steps to align the 18 hexagonal segments of Webb’s mirror, marking nearly the halfway point in a complex, weeks-long process. The second and third stages were respectively called segment alignment and image stacking, … Read more
It’s been nearly 350 years since Sir Issac Newton wrote, “If I have seen further it is by standing on the shoulders of giants,” but the sentiment certainly holds true today. Newton’s wisdom is exemplified by a grand project called the Cosmic Evolution Survey, or COSMOS. COSMOS builds on the legacy of the Hubble Space … Read more
Several instruments are preparing to help the James Webb Space Telescope with its mirror alignment and future observations, with several key steps achieved in recent days, according to NASA. The filter wheel for the Near Infrared Imager and Slitless Spectrograph (NIRISS) has been successfully calibrated, allowing this key part of the Fine Guidance System (FGS) … Read more
The Hubble Space Telescope continues to scout on behalf of the newly launched James Webb Space Telescope to guide future astronomy work. A stunning new image released by Hubble officials shows a single example of that collaboration: a pair of galaxies known as Arp 298, interacting 200 million light-years from Earth in the constellation Pegasus. … Read more
The James Webb Space Telescope will study the weirdly flickering black hole at the heart of our galaxy, the Milky Way, which has proved elusive for existing telescopes to explore. Webb will join the efforts of numerous telescopes to understand the nature of the supermassive black hole called Sagittarius A*, whose tendency to flare up … Read more
One of the James Webb Space Telescope‘s first studies will seek to tell us more about 19 nearby galaxies and how they fit into our neighborhood’s history. The infrared images taken from deep space will allow Webb’s data to add galactic information about star formation, strong winds blowing off these stars to disturb gas and … Read more
The James Webb Space Telescope finished the first major stage in its long process of aligning the observatory’s 18-segmented primary mirror. A single star that the observatory looked at was deliberately rendered 18 times into a hexagonal shape. Eventually, those 18 images will perfectly align into a single, sharp focus, but the interim result portrays … Read more
The next time a space rock races through our solar system from beyond, humans will be a little more prepared to unlock its secrets. To date, astronomers have identified two interstellar objects that came from other neighborhoods and rushed through the solar system. In 2017, there was ‘Oumuamua, and in 2018, Borisov followed, giving scientists … Read more
The James Webb Space Telescope‘s key pointing instrument is working well in testing, according to two space agencies involved with the observatory’s commissioning work. The Fine Guidance Sensor (FGS), a contribution from Honeywell on behalf of the Canadian Space Agency, successfully “locked on” to a specific guide star in tracking mode on Sunday (Feb. 13), … Read more
