The James Webb Space Telescope stamp is being issued as a Forever® stamp in panes of 20. Overall development was led and managed by NASA.Īrt director Derry Noyes was the designer for the stamp project using existing art by James Vaughan and an image provided by NASA/STScI. Webb represents multinational cooperation of NASA, the European Space Agency, and the Canadian Space Agency. The telescope may identify planets with conditions advantageous for supporting life as we know it. Webb will provide views of the universe in its infancy, including galaxies during their formation. The selvage image of a star and distant space was taken by Webb early in its mission, brilliantly confirming the perfect alignment of the telescope’s 18 mirror segments. Below are Webb’s solar shield, computers, control machinery, and the solar array that provides power. The secondary mirror, supported by three struts, is opposite the primary mirror. Webb’s 18 gold-coated mirror segments-hexagons that combine to form its 21-foot-wide primary mirror-can pick up faint heat waves representing the universe’s first accessible starlight from billions of light-years away. The image on the stamp is an artist’s digitally created depiction of the telescope against a dazzling starscape. Launched on December 25, 2021, Webb now orbits the Sun about a million miles away from Earth. Postal Service celebrates the James Webb Space Telescope (Webb), the largest and most sensitive telescope ever deployed in space- capable of peering directly into the early cosmos and to the limits of the known universe. The resulting dust cloud temporarily blocked the starlight, NASA said, and within a half year, Betelgeuse was as bright as before.With this stamp, the U.S. Scientists expect Betelgeuse to be short-lived, given its mass and the speed at which it’s burning through its material.Īfter countless centuries of varying brightness, Betelgeuse dimmed dramatically in 2019 when a huge bunch of surface material was ejected into space. It’s so huge that if it replaced our sun, it would stretch beyond Jupiter, according to NASA.Īt just 10 million years old, Betelgeuse is considerably younger than the 4.6 billion-year-old sun. A light-year is 5.8 trillion miles.īetelgeuse is thousands of times brighter than our sun and some 700 times bigger. ![]() Binoculars and small telescopes will enhance the view. “Which scenario we will see is uncertain, making the event even more intriguing,” said astronomer Gianluca Masa, founder of the Virtual Telescope Project, which will provide a live webcast from Italy.Īn estimated 700 light-years away, Betelgeuse is visible with the naked eye. If it's a total eclipse, astronomers aren’t sure how many seconds the star will disappear completely, perhaps up to 10 seconds. Rather, the result could be a “ring of fire” eclipse with a miniscule blazing border around the star. It's unclear if the asteroid will obscure the entire star, producing a total eclipse. There are lingering uncertainties over those predictions as well as the size of the star and its expansive atmosphere. By observing an eclipse of a much dimmer star by Leona in September, a Spanish-led team recently estimated the asteroid to be about 34 miles wide and 50 miles long (55 kilometers wide and 80 kilometers long). The asteroid is Leona, a slowly rotating, oblong space rock in the main asteroid belt between Mars and Jupiter.Īstronomers hope to learn more about Betelgeuse and Leona through the eclipse, which is expected to last no more than 15 seconds. The star is Betelgeuse, a red supergiant in the constellation Orion. The rare and fleeting spectacle, late Monday into early Tuesday, should be visible to millions of people along a narrow path stretching from central Asia’s Tajikistan and Armenia, across Turkey, Greece, Italy and Spain, to Miami and the Florida Keys and finally, to parts of Mexico. (AP) - One of the biggest and brightest stars in the night sky will momentarily vanish as an asteroid passes in front of it to produce a one-of-a-kind eclipse.
