Ganymede's surface temperature varies strongly throughout the day, and around noon near the equator it may become sufficiently warm that the ice surface releases (or sublimates) some small amounts of water molecules.
NASA anticipates that Hubble will last for many more years and will continue making groundbreaking observations, working in tandem with other space observatories including the James Webb Space Telescope to further knowledge of the cosmos.
Washington: Astronomers have found the best evidence for a black hole of an elusive class known as “intermediate-mass” by using the combined power of two X-ray observatories and the keen vision of NASA’s Hubble Space Telescope. Weighing in at about 50,000 times the mass of our Sun, the black hole is smaller than the supermassive […]
Washington: NASA’s Hubble Space Telescope has captured a formation of galaxies that looks like a smiling face, said the US space agency. On Saturday, it posted an image on its Instagram handle that showed two yellow orbs above an arc of light — painting a smiley face in space. Asking its followers to find the […]
Washington: NASA’s Hubble Space Telescope has returned to normal operations and completed its first science observations after a three-week hiatus owing to a failed gyroscope. The observations were of the distant, star-forming galaxy and were taken in infrared wavelengths with the Wide Field Camera 3 instrument. The return to conducting science comes after successfully recovering a […]
New York: Using the Hubble Space Telescope and the Kepler Space Telescope, astronomers have found the first compelling evidence for a Neptune-sized moon orbiting a giant gas planet 8,000 light-years away. The detection of the candidate exomoon — moons orbiting planets in other star systems — is unusual because of its large size, comparable to […]
Washington: NASA’s Hubble Space Telescope has captured the farthest active inbound comet ever seen, at a whopping distance of 1.5 billion miles from the Sun. Slightly warmed by the remote Sun, it has already begun to develop an 80,000-mile-wide fuzzy cloud of dust, called a coma, enveloping a tiny, solid nucleus of frozen gas and […]
Washington: NASA is set to reveal this week at a news conference new results about ocean worlds in our solar system. The announcements will be related particularly to findings from the agency’s Saturn probe Cassini spacecraft and the Hubble space telescope, NASA said in a statement. These new discoveries will also help inform future ocean […]
New York: The number of distant galaxies could be 10 to 100 times fewer than earlier thought, astronomers estimate. Over the years, the Hubble Space Telescope has allowed astronomers to look deep into the universe. The long view stirred theories of untold thousands of distant, faint galaxies. “Our work suggests that there are far fewer […]
