The light from the most distant and earliest galaxies and stars, once blue, is now infrared “heat” radiation, invisible to the eye. What began as the Next Generation Space Telescope evolved into an infrared telescope capable of sensing the heat from the earliest stars and galaxies in the universe.īecause the cosmos is expanding, those earliest stars and galaxies are rushing away from Earth so fast that their light is shifted to longer, redder wavelengths, much as the sound from an ambulance’s siren shifts to a lower register as it speeds by. Three of those planets are Earth-size rocks orbiting in the habitable zone, where water could exist on the surface. Two other studies will be devoted to exoplanets, including the Trappist-1 system, just 40 light-years away, where seven planets circle a dim red-dwarf star. Jupiter and its myriad intriguing satellites, such as Europa, the target of an upcoming NASA mission, will be one focus. The Early Release Science Programs, intended to jump-start the Webb era, include studies of the solar system, galaxies, intergalactic space, massive black holes and the evolution of stars. Now that the images are out, “there will be an astronomer feeding frenzy!” Garth Illingworth, a researcher at the University of California, Santa Cruz, and an initiator of the telescope program four decades ago, wrote in an email.
On Thursday, all the data gathered during the testing of the telescope and its instruments will become available. Biden on Monday, will be available later this week.
Some results, including images of galaxies even more distant than the one shown by Mr. These will be followed in the next six months by the results of studies in NASA’s Early Release Science Programs. The pictures and other data released on Tuesday were selected by a small team of imaging experts and public outreach specialists for the images’ ability to show off the new telescope’s range and power - and to knock the public’s socks off. Such molecules drift through space, settling in clouds that then give birth to new stars, planets, asteroids - and whatever life might subsequently sprout. Indeed, the image revealed a band of dust that was being heated up as two of the galaxies ripped stars from each other.Ī view of the Southern Ring nebula, the remnants of an exploded star, revealed hints of complex carbon molecules known as polycyclic aromatic hydrocarbons, or PAHs, floating in its midst. Four are so closely engaged in a gravitational dance that they will eventually merge. One infrared skyscape showed Stephan’s Quintet, five galaxies packed improbably tightly in the constellation Pegasus. A few miles away at the Space Telescope Science Institute in Baltimore, an overflow crowd of astronomers whooped and hollered, oohed and aahed, as new images flashed on the screen - evidence that their telescope was working even better than hoped. Double Tethered Metallacyclobutane Catalyst for Cyclic Polymer Synthesis.The new pictures were rolled out during an hourlong ceremony at the Goddard Space Flight Center that was hosted by Michelle Thaller, the center’s assistant director for science communication, with video stops around the world.
