- Webb has also performed a spectroscopy and gathered an image using foreground galaxy clusters.
- The Carina Nebula is known for its tall pillars.
James Webb Telescope Updates: The James Webb Space Telescope will be able to capture hitherto unobserved vistas of far-off galaxies, dazzling nebulae, and a distant big gas planet in its initial cosmic photos, according to NASA on Friday.
The $10 billion observatory, which will replace Hubble and provide fresh insights into the universe’s beginnings, is expected to make its first observations on July 12. The US, European, and Canadian space agencies are getting ready for a big reveal.An astronomer at the STSI, which is in charge of Webb, Klaus Pontoppidan, said to AFP last week, “I’m looking forward to not having to maintain these secrets anymore, it will be a huge relief.”
The Carina Nebula, a massive cloud of gas and dust located 7,600 light years away, as well as the Southern Ring Nebula, which encircles a fading star 2,000 light years away, were selected as part of the first batch of fullcolor scientific photos by an international committee.The three-light-year-tall “Mystic Mountain,” a celestial pinnacle that Hubble famously captured in a photograph, is one of the towering pillars that make up the Carina Nebula renowned.
Webb has also performed spectroscopy on the distant gas giant WASP96 b, which was discovered in 2014. Spectroscopy is an analysis of light that provides detailed information.WASP96 b is almost half the mass of Jupiter and travels in about 3.4 days around its star while being nearly 1,150 light-years from Earth.Stephan’s Quintet, a small galaxy 290 million light years away, is the next object. According to NASA, four of the quintet’s five galaxies are “engaged in a cosmic dance of repeated close encounters.”
Last but not least, and possibly the most fascinating of all, Webb has assembled an image employing foreground galaxy clusters named SMACS 0723 as a type of cosmic magnifying glass for the incredibly far away and faint galaxies behind it.This process, called “gravitational lensing,” works like a pair of glasses by using the mass of the foreground galaxies to bend the light of things behind them.
Dan Coe, an astronomer at STSI, told AFP on Friday that the telescope has made scientific advancements even in its initial photographs.He stated, “I looked at the photographs, and I instantly learnt three things about the universe that I didn’t know before. I first saw the images… of this deep field of this galaxy cluster lensing.It completely blew my head.Webb can look farther back in time to the Big Bang, which occurred 13.8 billion years ago, than any instrument before it thanks to its infrared capabilities.The light from the first stars moves from the shorter ultraviolet and visible wavelengths it was emitted in to longer infrared wavelengths as the universe expands, which Webb is able to detect with an unprecedented level of resolution.
