![]() TESS's examination of Vega and similar stars will help scientists learn more about the early stages of star evolution. This four-stage launcher a European Space Agency (ESA) program is tailored to carry the growing number of small scientific spacecraft and other. ![]() While the primary mission of TESS is to search for exoplanets, the satellite will also search for signs of star variability. The Arianespace commercial launcher family was expanded in 2012 with the addition of Vega, a new-generation vehicle for flights with small- to medium-sized satellite payloads. Scientists are examining bright stars like Vega more closely using NASA's TESS (Transiting Exoplanet Survey Satellite) mission, which launched in 2018 to conduct an all-sky survey. The layout (which resembled that found near the star Fomalhaut) suggests that there are two areas: an outer region with icy asteroids and a region closer to the star, where warmer space rocks reside. In early 2013, astronomers announced that they had discovered an asteroid belt surrounding Vega, suggesting the possibility of planets within the rocks' midst. The star, which rotates every 12.5 hours, is at 90 percent of its critical rotation speed, or the velocity at which the object would tear itself apart. Telescopic observations in 2006 revealed that Vega is whipping around so quickly that its poles are several thousand degrees warmer than its equator. ![]() Starring Jodie Foster, the movie followed an astronomer working on the search for extraterrestrial intelligence (SETI) who discovers a signal appearing to emanate from Vega. Vega rose to prominence in popular culture in the late 1990s after Carl Sagan's novel " Contact" (1985, Simon & Schuster) was adapted into a Hollywood movie. amateur astronomer Henry Draper was the first to break down Vega's light to reveal the various elements that make up the star. The star was also chosen for the first spectrographic image, in 1872. Astronomers captured the image through the daguerreotype process at Harvard College Observatory, using a 15-inch (38 centimeters) refractor, on July 16-17, 1850. In modern times, Vega was the first star to be photographed, other than the sun. "Thus, hundreds of stars and constellations have Arabic names, such as Altair, Deneb, Vega and Rigel," wrote Nidhal Guessoum, an astrophysicist at the American University of Sharjah in the United Arab Emirates, in a 2013 article published in the journal Nature (opens in new tab). To find the star Vega in the constellation Lyra, look directly overhead.
