![]() Ices can supply planets with carbon, hydrogen, oxygen, nitrogen and sulfur, which could lead to the formation of a habitable planet like Earth, where they are used in planetary atmospheres as well as amino acids, sugars and alcohols. The starlight helped astronomers determine the diverse range of frozen molecules within the Chamaeleon I dark molecular cloud, which is forming dozens of young stars. More orange dots represent light from stars in the background, piercing through the cloud. The journal Nature Astronomy published a study including the image on Monday. A young protostar, called Ced 110 IRS 4, glows in orange to the left. The Webb telescope focused on the Chamaeleon I dark molecular cloud, which appears blue in the new image. Dense clumps within these clouds can collapse to form young stars called protostars. Molecular clouds are interstellar groupings of gas and dust where hydrogen and carbon monoxide molecules can form. The James Webb Space Telescope peered inside a wispy molecular cloud located 630 light-years away and spied ices made of different elements. This star in the constellation Sagittarius, officially known as WR 124, is 30 times as massive as our sun and already has shed enough material to account for 10 suns, according to NASA. It's really exciting," said Macarena Garcia Marin, a European Space Agency scientist who is part of the project. Such a transformation occurs only with some stars and normally is the last step before they explode, going supernova, according to scientists. 243 NASA: Dominic Hart / NASA/ Ames (bl). The Hubble Space Telescope snapped a shot of the same transitioning star a few decades ago, but it appeared more like a fireball without the delicate details.

A light-year is about 5.8 trillion miles. Its infrared eyes observed all the gas and dust flung into space by a huge, hot star 15,000 light-years away. The observation was among the first made by Webb following its launch in late 2021. These latest Io images were taken during Juno's 49th trip around Jupiter.The Webb Space Telescope has captured the rare and fleeting phase of a star on the cusp of death. But other moons in our solar system could potentially contain suitable conditions for life to evolve in their subsurface, like the Saturnian moons Enceladus and Mimas (and, of course, Europa). It's extremely unlikely a world swimming in lava could host conditions for even the hardiest of life to evolve. All this heat seeks to reach the surface, resulting in molten lava and extreme volcanism. This powerful push and pull creates profound heat inside a world that's a little larger than our moon. Io is tortured because it's stuck in a relentless "tug-of-war" between the massive Jupiter and two of Jupiter's other big moons, Ganymede and Europa - a world that might harbor a sizable ocean. "It's a real tortured moon," Bolton, who works at the Southwest Research Institute, a research organization that often partners with NASA, added. "We're marching closer and closer," Scott Bolton, the Juno mission's principal investigator, told Mashable.Ī speeding object collided with Jupiter and blew up, cool space footage shows (For reference, the moon is some 240,000 miles from Earth.) By year's end, the spacecraft will pass just some 930 miles, or 1,500 kilometers, from Io. Juno will swoop progressively nearer to Io as it loops around Jupiter and approaches the dynamic moon's orbit. In 2023, the views of Io will get increasingly clearer and more intriguing. The images allow planetary scientists and the public to spot surface features and volcanoes on Io - the most volcanically active world in our solar system. ![]() The March 1 images are Juno's "best images so far of Io's colorful surface," Jason Perry, a professional imaging processor who uploaded new photos to NASA's Juno website, noted online (Opens in a new tab). The pioneering Juno spacecraft, which arrived at Jupiter in 2016 and is now swooping by the planet's intriguing moons, recently snapped images of the Jovian moon Io from some 32,044 miles (51,570 kilometers) away. There's a moon teeming with lava-spewing volcanoes in our solar system, and a NASA spacecraft is getting closer to this intense world. ![]()
