Two galaxies, NGC 4532 and DDO 137, are falling into the Virgo Cluster at 547 miles per second, creating a massive gas bridge and tail due to tidal forces and ram-pressure stripping, providing insights into galaxy evolution and star formation.
Astronomers have discovered the longest gas bridge ever observed, linking two galaxies, NGC 4532 and DDO 137, on the outskirts of the Virgo Cluster. This massive structure, extending 185,000 light-years, is formed by tidal forces and ram pressure from the hot gas surrounding the cluster, illustrating how galaxy environments influence their evolution and gas dynamics over billions of years.
The Vera C. Rubin Observatory released its first detailed image of the Virgo Cluster, capturing over 10 million galaxies and various cosmic phenomena, including spiral galaxies, galaxy collisions, and nearby stars, showcasing the universe's vastness and complexity.
The Vera Rubin Observatory in Chile has captured detailed images of the universe, including the Virgo cluster, revealing millions of galaxies and aiding in the study of dark matter and dark energy through its upcoming 10-year Legacy Survey of Space and Time.
Astronomers using the Hubble Space Telescope have studied the globular cluster system of the ultra-diffuse galaxy VCC 615, located in the Virgo Cluster. The study identified 22 globular cluster candidates and estimated the total globular cluster population to be 25.1, indicating a high specific frequency compared to similar dwarf galaxies. The findings suggest a large mass-to-light ratio for VCC 615, with a total mass between 90 and 160 billion solar masses. The galaxy's compact nucleus may eventually form a new ultracompact dwarf galaxy.
NASA's Hubble Space Telescope has captured a distant dwarf galaxy in the Virgo cluster, located 52 million light-years away from Earth, revealing cosmic wonders and sparking awe among viewers worldwide. The image, shared on Instagram, highlights the galaxy's location and the challenges it faces within the Virgo cluster, shedding light on the impact of cosmic forces such as ram pressure. The post has garnered immense attention, with enthralled netizens expressing profound fascination with the mysteries of the universe unveiled by the Hubble Space Telescope.
Astronomers have discovered the eroding remains of 100 dwarf galaxies that have been stripped of their outer layer of stars by larger galaxies, providing evidence for the existence of a "missing link" in the evolution of ultra-compact dwarf galaxies (UCDs). UCDs are extremely dense collections of stars that have puzzled scientists for years. The newly discovered galaxies are in the process of transitioning into UCDs, confirming the theory that UCDs are the remnants of destroyed dwarf galaxies. The findings suggest that there are likely many more low-mass remnants to be found.
New research using the Gemini North Telescope has observed galactic cannibalism near the Virgo Cluster, where larger galaxies merge with and consume smaller ones. However, some smaller galaxies are dense enough to survive the merger and become Ultra Compact Dwarfs (UCDs). These UCDs retain their cores and exhibit tight groupings of stars, indicating their gravitational grip is strong enough to withstand the merger. The study suggests that many UCDs are remnants of ancient dwarf galaxies in galaxy clusters, and there are likely more low-mass remnants to be found.
Astronomers using the Gemini North telescope have discovered over 100 dwarf galaxies transitioning into ultra-compact dwarf galaxies, confirming that many ultra-compact dwarf galaxies are the remnants of stripped dwarf galaxies. This fills in the missing link in understanding the formation of ultra-compact dwarf galaxies, which are more compact than other galaxies with similar mass but larger than star clusters. The findings provide valuable insights into the evolutionary process and the role of the local environment in the formation of these enigmatic objects.
The Hubble Space Telescope has captured a stunning image of the galaxy NGC 4654 in the Virgo Cluster, located 55 million light-years from Earth. Scientists believe that NGC 4654 interacted with another galaxy over 500 million years ago, which stripped it of some gas and limited star formation. Studying galaxies like NGC 4654 helps researchers understand how stars form and could provide insights into the formation of planets. The image showcases the swirling spiral arms of the galaxy and highlights its asymmetric distribution of stars and neutral hydrogen gas.
NASA's Hubble Space Telescope captures a stunning image of a vibrant galaxy in the Virgo Cluster, showcasing the beauty and diversity of celestial objects in our universe.
NASA's Hubble Space Telescope has captured a breathtaking image of the Sombrero galaxy, located 28 million light-years away on the southern edge of the Virgo cluster. The image shows the galaxy in visible light, revealing its 50,000 light-year diameter and a central black hole estimated to be a billion times more massive than the Sun. The left and right edges of the galaxy appear red, the middle of the rings yellow-green, and the center light blue with a white core.
Astrophotographer Miguel Claro captured a stunning image of the Virgo Cluster, a collection of galaxies located in the constellation of Virgo, showing more than 1,890 galaxies at a distance of 48 million light-years away from Earth. The image was captured over the course of 11 nights at Portugal's Alqueva Observatory and features galaxies immersed in star-forming clouds. The Virgo Cluster forms the heart of the larger Virgo Supercluster, which includes our own Milky Way galaxy.
