Part of an investigation to understand how galaxies can grow to such enormous sizes, UGC 2885 was also part of An Interesting Voyage and astronomer Vera Rubin's pioneering study of the rotation of spiral galaxies. That's about 10 times as many stars as the Milky Way. Some 800,000 light-years across compared to the Milky Way's diameter of 100,000 light-years or so, it has around 1 trillion stars. In sharp focus beyond is UGC 2885, a giant spiral galaxy about 232 million light-years distant. In this Hubble Space Telescope image, the bright, spiky stars lie in the foreground toward the heroic northern constellation Perseus and well within our own Milky Way galaxy. It has certainly proved fruitful as most of Hubble's images have been captured by the ACS. ![]() The data revealed that beneath Europa's icy surface, there is evidence of a hidden and global. ![]() However, this image dates back to the late 1990s when the Galileo spacecraft explored the Jovian system, capturing several amazing images of Europa. Discover the cosmos Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. The Advanced Camera for Surveys (ACS) was primarily designed to survey large areas of the sky at visible and red wavelengths with 10 times greater efficiency than the earlier premier Hubble camera. Today's NASA Astronomy Picture of the Day even brings a stunning view of Europa by Galileo spacecraft. A different astronomy and space science related image is featured each day, along with a brief explanation. NASA further explains the image that "Galileo's Europa image data has been remastered here, with improved calibrations to produce a colour image approximating what the human eye might see.To capture such objects, Hubble has advanced optical instruments such as the Advanced Camera for Surveys and Wide Field Camera 3. The data revealed that beneath Europa's icy surface, there is evidence of a hidden and global ocean. ![]() Today's NASA Astronomy Picture of the Day even brings a stunning view of Europa by Galileo spacecraft. Snapshots of celestial objects like galaxies, black holes, nebulae, and more, were captured by astrophotographers from all over the world and have been shared by NASA. Interestingly, Europa is a popular destination as it has been visited by several spacecraft and more missions are planned in the future. Over the past few months, we have seen several stunning snapshots of celestial objects as part of NASA's Astronomy Picture of the Day, which is published on a daily basis. (NASA/Craig Stocks) The universe contains an astonishing number of stars, estimated to be around 200 billion trillion. Supernova SN 2023ixf was discovered by Japanese astronomer Koichi Itagaki just 3 days ago. ![]() This is because Europa's surface is composed of water ice that reflects approximately 5.5 times more sunlight than our Moon does. Discover the cosmos Each day a different image or photograph of our fascinating universe is featured, along with a brief. Today’s NASA Astronomy Picture of the Day is a snapshot of the supernova SN 2023ixf located near the M101 spiral galaxy. Europa is said to be about 90 percent the size of Earth's Moon! If we were to replace our Moon with Europa, it would have a similar apparent size in the sky, but it would be significantly brighter, NASA explains. Jupiter is the second planet in our solar system with the most number of moons at 95! Among these, the smallest of Jupiter's four Galilean moons is Europa which is the sixth closest to the planet. ![]()
