Hubble space telescope images 200312/6/2023 ![]() Thus, IC 5332 is an intermediate spiral galaxy on many fronts: weakly barred, with quite loosely wound arms, and almost completely face-on. The lowercase "c" describes how tightly wound the spiral arms are: "a" would indicate very tightly wound, and "d" very loosely wound. ![]() SAB galaxies-which are also known as intermediate spiral galaxies-do not have a clear bar-shape at their core, but also do not spiral out from a single point, instead falling somewhere in between. The majority of spiral galaxies do not spiral out from a single point, but rather from an elongated bar-type structure. It means that the galaxy is weakly barred, which refers to the shape of the galaxy's center. The "AB" designation is a little more complex. The "S" identifies it as a spiral galaxy, which it clearly is, given its well-defined arms of bright stars and darker dust that curl outwards from the galaxy's dense and bright core. IC 5332 is an SABc-type galaxy in the De Vaucouleurs system of galaxy classification. Webb, with its ability to peer past the clouds of dust enveloping young stars, will revolutionise the study of outflows from young stars.In contrast, if the galaxy's orientation is such that it appears squashed and oval-shaped, then we say that it is "edge-on." The key thing is that the same galaxy would look extremely different from our perspective depending on whether it was face-on or edge-on as seen from Earth. The second study instead investigated the outflows themselves to lay the groundwork for future observations with the NASA/ESA/CSA James Webb Space Telescope. The first delved into the structure and motion of the Herbig–Haro objects visible in this image, giving astronomers a better understanding of the physical processes occurring when outflows from young stars collide with surrounding gas and dust. In the case of HH 1/2, two groups of astronomers requested Hubble observations for two different studies. Each of these filters is sensitive to just a small slice of the electromagnetic spectrum, and they allow astronomers to pinpoint interesting processes that emit light at specific wavelengths. ![]() This scene from a turbulent stellar nursery was captured with Hubble’s Wide Field Camera 3 using 11 different filters at infrared, visible, and ultraviolet wavelengths. Hubble has helped resolve some long-standing problems in astronomy, while also raising new questions. In 2002 Hubble observations revealed that parts of HH 1 are moving at more than 400 kilometres per second! Hubble Extreme Deep Field image of space in the constellation Fornax. Herbig–Haro objects are glowing clumps found around some newborn stars, and are created when jets of gas thrown outwards from these young stars collide with surrounding gas and dust at incredibly high speeds. Meanwhile, the bright star between that jet and the HH 1 cloud was once thought to be the source of these jets, but it is now known to be an unrelated double star that formed nearby. However, an outflow of gas from one of these stars can be seen streaming out from the central dark cloud as a bright jet. While both Herbig–Haro objects are visible, the young star system responsible for their creation is lurking out of sight, swaddled in the thick clouds of dust at the centre of this image. HH 1 is the luminous cloud above the bright star in the upper right of this image, and HH 2 is the cloud in the bottom left. Both objects are in the constellation Orion and lie around 1250 light-years from Earth. The lives of newborn stars are tempestuous, as this image of the Herbig–Haro objects HH 1 and HH 2 from the NASA/ESA Hubble Space Telescope depicts.
