The Hubble Space Telescope captured a stunning image of the spiral galaxy NGC 3370 in Leo, which is crucial for understanding galaxy formation and measuring cosmic distances using Cepheid variables and Type Ia supernovas, helping to refine our knowledge of the universe's expansion.
The Hubble Space Telescope captured an edge-on view of the spiral galaxy UGC 10043, located 150 million light-years away in the constellation Serpens. This perspective highlights the galaxy's disk as a sharp line with dust lanes obscuring its glow, while active star-forming regions and a prominent central bulge are visible. The bulge's size and the disk's warp may result from material siphoned from a nearby dwarf galaxy. The image is a composite of data collected 23 years apart, showcasing Hubble's long-term contributions to astronomy.
The Hubble Space Telescope has captured a stunning image of the grand design spiral galaxy NGC 5643, located 40 million light-years away in the constellation Lupus. This galaxy features prominent spiral arms and a bright active galactic nucleus powered by a supermassive black hole. Additionally, an even brighter X-ray source, NGC 5643 X-1, is believed to be a smaller black hole on the galaxy's outskirts, emitting intense radiation as it pulls material from a companion star.
The Hubble Space Telescope has been observing the spiral galaxy UGC 10043, located 150 million light-years away, for over 23 years. Initially captured in 2000, Hubble revisited the galaxy in 2023, combining data from both years to create a detailed image. This long-term observation allows astronomers to study the galaxy's evolution, revealing features like a large bulge possibly caused by interactions with nearby dwarf galaxies. Hubble's ability to capture images across different wavelengths provides unique insights into the galaxy's structure and star formation.
The Hubble Space Telescope has captured a unique edge-on image of the spiral galaxy UGC 10043, located 150 million light-years away in the constellation Serpens. This perspective reveals the galaxy's disk as a sharp line with prominent dust lanes and a visible central bulge. The unusual view is attributed to the galaxy's large bulging disk, possibly due to material siphoning from a nearby dwarf galaxy. The image is a composite of frames taken 23 years apart, showcasing Hubble's long-term data collection capabilities.
Astronomers have used the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA) to study the giant spiral galaxy ADF22.A1, located in the SSA22 proto-cluster at a redshift of 3.09. The observations revealed a spiral-like stellar structure and a bright, compact dusty core, indicating active star formation and growth of a proto-bulge. The galaxy's rotation velocity was measured at about 530 km/s, suggesting rapid disk spin-up possibly due to cold accretion and mergers. These findings provide new insights into the evolution of massive galaxies and supermassive black holes.
The Hubble Space Telescope captured a detailed image of the spiral galaxy NGC 4731 in the Virgo constellation, showcasing its colorful gas clouds, dust bands, star-forming regions, and prominent bar structure.
