James Webb Space Telescope plans probe of massive star radiation

by

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

Massive solar telescope starts science observations

by

The Daniel K. Inouye Solar Telescope (DKIST) is starting its first operational science work as it embarks on a mission to better understand our sun. DKIST is a nearly $300 million science observatory perched atop the 10,062-foot (3,067 meters) Mount Haleakalā in Maui, Hawaii. One of its main functions will be to study the corona, the … Read more

For The First Time, a Tatooine-Like Planet Has Been Detected Via a Wobbling Star

by

Not all planetary systems are alike. Out there in the big, wide galaxy, a number of different configurations have been spotted, some vastly different from our home system. These include extrasolar planets, or exoplanets, that orbit not one, but two stars, like the fictional Star Wars world of Tatooine.   Now, for the first time, astronomers … Read more

James Webb Space Telescope is nearly halfway through its mirror alignment stages

by

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

Major James Webb Space Telescope project will map half a million early galaxies

by

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

James Webb Space Telescope instrument checkouts on track amid mirror alignment

by

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

Hubble eyes two stunning galaxies before future James Webb Space Telescope observations

by

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

Hubble telescope spots a ‘Space Triangle’ galaxy crash spawning new stars

by

A head-on collision between galaxies has created a vast, cosmic triangle in deep space glittering with star formation in a new image captured by the Hubble Space Telescope. The new photo, which NASA released Tuesday (Feb. 22), shows a pair of colliding galaxies known as called Arp 143 arranged in a what scientists described as … Read more

James Webb Space Telescope will study Milky Way’s flaring supermassive black hole

by

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
