Astronomers using the James Webb Space Telescope looked at Earendel, the farthest star ever detected, following previous observations from NASA's Hubble Space Telescope.
Theoretical physicist Dr. Michio Kaku explains the significance of new images provided by NASA's Webb Space Telescope on 'Sunday Night in America.'of Earendel – the farthest star ever detected – reveal a massive B-type star that is more than twice as hot as our sun and a million times more luminous.
NASA said that Earendel – which means"morning star" in Old English and is, perhaps, a familiar-sounding name to fans of"The Lord of the Rings" trilogy – is located in the Sunrise Arc galaxy. The galaxy cluster, located between Earth and the star, is so massive that it warps the fabric of space, producing a magnifying effect that allows astronomers to look through it.
Due to this, scientists have determined the object is magnified by a factor of at least 4,000 and is extremely small.Webb’s NIRCam instrument reveals the star, nicknamed Earendel, to be a massive B-type star more than twice as hot as our sun, and about a million times more luminous.Due to the color of Earendel, astronomers also believe they can see hints of a cooler, redder companion star.

A 'Question Mark' Formation Was Documented in SpaceScientists speculated it was one or more galaxies. The viral photograph was authentic, though it was a zoomed-in version of a larger image by NASA's Webb Space Telescope. The telescope's image was a composite of multiple exposures taken by its Near-Infrared Camera (NIRCam). Documenting a pair of forming stars (the bright, colorful objects in the image's center), the image was published on the telescope's official website on July 26, 2023.
