Whenever scientists observe the large expense of space, they are often only able to capture events after they have occurred. This is because objects in space are in constant motion, and most of the time, their motions are quick and brief. In a recent discovery, NASA has found the rapid transition of a cosmic object. Why do Astronauts study stars and nebulae? For most of us, the night sky is but a blanket of quiet spectacle. Whenever we look up, we can see stars twinkling at far distances, but how many stop to wonder what they are close up? The stars we see at a far distance are glowing balls of gas. And like everything within our universe, they undergo life cycles from birth to death. Whenever a star is born, it undergoes a process driven by nuclear fusion between gases, most of which are hydrogen and helium. When stars near the end of their life, they exhaust their nuclear fuel and enter a transition phase that forms what is known as a planetary nebula. During the nebula phase, stars begin to shed their mass into space, releasing heavy elements that could enrich the formation of future stars and even planets. Earth was formed from such a process; hence, astronauts and scientists are always on the lookout to capture events where a star is born or dies, transforming into newer planets or cosmic elements. NASA scientists capture rare Calabash nebula Recently, NASA has released an image of a calabash nebula in space. This structure was captured during a transitioning phase as its central star begins to exit its red giant phase. It is called a calabash nebula due to its resemblance to a gourd. However, this transitioning phase is occurring at an incredible speed of 1 million miles per hour. At this stage, the star is beginning to expel heavy gas and dust in intense jets. These fly in opposing directions toward surrounding cosmic material that creates glowing lobes in space. Although NASA was unable to capture this event in duration, they were able to study the glowing lobes created by these flying space jets, like this ‘frozen block of life’ discovery, near a young star. What they observed close up were materials colliding with surrounding gas and structures that light up across different wavelengths. This image was captured in February 2017 using NASA’s Hubble Space Telescope. Following the event, scientists from NASA have analyzed the surrounding matter being ejected and discovered this star to have been a low-mass star. Why is this nebula so different from classic planetary nebulae There are tens of thousands of planetary nebulae in our Milky Way galaxy alone. But the Calabash Nebula observed by NASA is rarely ever seen because it is in a transitional phase. However, in its brief moment, the asymmetric nebula reveals cosmic dynamics and fields that are hardly observed on planetary nebulae. The importance of this glowing discovery for NASA Many occurrences in space are windows of curiosity for both scientists and stargazers. However, for scientists, especially at NASA, there is a demanding responsibility to account for these events. For them, the Calabash Nebula isn’t just a brief visual in space; there is a need to provide empirical data that accounts for its occurrence. In doing so, NASA can add it to previously stated theories on how stars transition into nebulae. Also, they can update established models intended to simulate the events of a new or dying star. Moments like this are complementary on several levels. That is because interstellar events are often invisible or difficult to observe beyond their twinkling lights. Now, NASA is developing newer technologies to discover the occurrence of other Calabash Nebulae that could be observed in space, just like this mysterious, powerful star eruption discovery.
