It works by blocking out the brighter object's light, which makes it possible to capture the dimmer object nearby. The equipment allows astronomers to take pictures of very faint objects around a central bright object, a NASA fact sheet says. However, these images were constructed with JWST's Near infrared Camera (NIRCam), which covers infrared wavelength range from 0.6 to 5 microns. Uranus is a blue-green colour due to the large amount of methane in the atmosphere which absorbs red light but allows blues to be reflected into space. Uranus will reach its next solstice in 2028. NASA says the polar cap appears to become more prominent when the planet's pole begins to point towards the sun, as it approaches solstice and receives more sunlight. ![]() These include the bright, white, inner cap and the dark lane at the bottom of the polar cap, toward the lower latitudes. But the hints of the detailed science we're going to be able to do with them is what makes me so excited.One of the most exciting features in this new image is the planet's seasonal north polar cloud cap. "They're amazing in themselves just as images. "I have seen the first images and they are spectacular," deputy project scientist Dr Amber Straughn said of Tuesday's further release. Nasa scientists are in no doubt that Webb will fulfil its promise. But it is hoped that one day, Webb might spy a planet that has gases in its air that are similar to those that shroud the Earth - a tantalising prospect that might hint at the presence of biology. WASP-96 b orbits far too close to its parent star to sustain life. It will tell us about the chemistry of that atmosphere. Webb has analysed the atmosphere of WASP-96 b, a giant planet located more than 1000 light-years from Earth. One of the topics to be discussed will touch on that other overarching goal: the study of planets outside our solar system. Nasa and its international partners, the European and Canadian space agencies, will release further colour imagery from Webb later today. Webb identified its super-deep objects after only 12.5 hours of observations. Hubble used to stare at the sky for weeks on end to produce this kind of result. And since we know the Universe is 13.8 billion years old, you're going back almost to the beginning." They're going back about 13 and a half billion years. "And by the way, we're going back further, because this is just the first image. And that light that you are seeing on one of those little specks has been travelling for over 13 billion years," Nasa administrator Bill Nelson said. "Light travels at 186,000 miles per second.

Scientists can tell from the quality of the data produced by Webb that the telescope is sensing space way beyond the most far-flung object in this image. Webb, with its 6.5m-wide golden mirror and super-sensitive infrared instruments, has managed to detect in this picture the distorted shape (the red arcs) of galaxies that existed a mere 600 million years after the Big Bang (the Universe is 13.8b years old).Īnd it is even better than that. ![]() It is a gravitational effect the astronomical equivalent of a zoom lens for a telescope. But the great mass of this cluster has bent and magnified the light of objects that are much, much further away. The cluster itself is not actually that far away - "only" about 4.6 billion light-years in the distance. It shows a cluster of galaxies in the Southern Hemisphere constellation of Volans known by the ungainly name of SMACS 0723. The image unveiled before President Biden showcased Webb's capabilities to pursue the first of these objectives. ![]() One is to take pictures of the very first stars to shine in the Universe more than 13.5 billion years ago the other is to probe far-off planets to see if they might be habitable. It will make all sorts of observations of the sky, but has two overarching goals. The $US10 billion ($NZ16.3b) James Webb Space Telescope (JWST), launched on 25 December last year, is billed as the successor to the famous Hubble Space Telescope. US President Joe Biden applauds the achievement.
