    A distant star system that scientists described as abnormal, chaotic, and strange is finally coming into focus, thanks to NASA's James Webb Space Telescope. Using its powerful Near-Infrared Camera (NIRCam), Webb has captured a rare image of one of two known planets orbiting the star 14 Herculis, located about 60 light-years from Earth in the Milky Way.The planet, known as 14 Herculis c, stands out for how incredibly cold it is. While astronomers have discovered nearly 6,000 exoplanets, only a small handful have been directly imaged, and most of those are extremely hot, with temperatures soaring into the hundreds or...

    This image of Uranus from NIRCam (Near-Infrared Camera) on NASA’s James Webb Space Telescope shows the planet and its rings in new clarity. The Webb image exquisitely captures Uranus’s seasonal north polar cap, including the bright, white, inner cap and the dark lane in the bottom of the polar cap. Uranus’ dim inner and outer rings are also visible in this image, including the elusive Zeta ring—the extremely faint and diffuse ring closest to the planet.

    Illustration of how a failed supernova can become a black hole. (P. Jeffries/STScI/NASA/ESA) In 2009 a giant star 25 times more massive than the Sun simply…vanished. Okay, it wasn't quite that simple. It underwent a period of brightening, increasing in luminosity to a million Suns, just as if it was ready to explode into a supernova. But then it faded rather than exploding. And when astronomers tried to see the star, using the Large Binocular Telescope (LBT), Hubble, and the Spitzer space telescope, they couldn't see anything. The star, known as N6946-BH1, is now considered a failed supernova. The BH1...
  • James Webb Space Telescope discovers water ice at ringed asteroid Chariklo 'by remarkable luck'

    The most comprehensive plans need a sprinkle of luck, even in space. VIDEO AT LINK In October 2022, the James Webb Space Telescope (JWST or Webb) watched as Chariklo, a tiny ringed asteroid, eclipsed a star. This event, called an occultation, marked a first for Webb. At the month's end, Webb turned toward Chariklo again and notched another victory: For the first time, astronomers analyzing the telescope's data spotted clear signs of water ice, the presence of which was only hinted at until now. These observations will guide astronomers to better understand the nature and behavior of tiny bodies in...
