1 00:00:00,001 --> 00:00:01,280 WATER VAPOR DETECTED IN EUROPA’S ATMOSPHERE 2 00:00:01,280 --> 00:00:05,760 New analysis of archival Hubble  data revealed water vapor in   3 00:00:05,760 --> 00:00:13,600 the atmosphere of Jupiter’s icy moon Europa. Europa's icy, smooth surface scarred by cracks   4 00:00:13,600 --> 00:00:24,080 and fissures averages -275 °F, but researchers  suspect a vast ocean lurks beneath that surface. 5 00:00:24,080 --> 00:00:28,240 The Hubble Space Telescope  previously detected 60-mile-high   6 00:00:28,240 --> 00:00:35,920 plumes of water vapor erupting like geysers. These new results show water vapor over a larger   7 00:00:35,920 --> 00:00:43,120 area, suggesting a long-term water vapor  atmosphere on one of Europa’s hemispheres. 8 00:00:43,120 --> 00:00:46,800 This discovery lays groundwork  for missions that will explore   9 00:00:46,800 --> 00:00:53,120 Jupiter’s icy moons. Understanding the  formation and evolution of Jupiter and   10 00:00:53,120 --> 00:01:01,648 its moons helps astronomers gain insights into  Jupiter-like exoplanets elsewhere in the universe. 11 00:01:01,648 --> 00:01:03,667 [ MUSIC ]
