NASA Launches James Webb Telescope With its Giant Sunshield to See First Galaxies, Distant Worlds

Rendering; ESA NASA’s James Webb Space Telescope officially launched on December 25. Its mission? To seek the light from the first galaxies in the early universe and to explore our own solar system, as well as planets orbiting other stars, called exoplanets. “The James Webb Space Telescope represents the ambition that NASA and our partners … Read more

UC Santa Cruz astronomers poised to join NASA’s search for signs of life in distant galaxies with new telescope   – Monterey Herald

Folded up inside its rocket-like origami, the James Webb Space Telescope lies in wait. The $10 billion instrument is set to launch as early as Christmas Eve to a gravitational sweet spot nearly a million miles from Earth, where it will tag along with us in orbit around the sun. During its journey, the telescope … Read more

Astronomers Feature In Detail Gigantic Cluster Of Galaxies

Italian astronomers performed X-ray observations of the massive cluster of galaxies ClG-J104803.7 + 313843, using ESA’s XMM-Newton spacecraft. The results of the observational campaign shed more light on the properties of this cluster. Galaxy clusters contain up to thousands of galaxies bound together by gravity. They are the largest known gravitationally binding structures in the … Read more

The Recipe for How Hubble Makes Beautiful Color Images of Distant Galaxies

This stellar whirlpool is actually a spiral galaxy known as NGC7329, and the image shown above was taken by Hubble’s Wide Field Camera 3, or WFC3. Creating a color image like this using a telescope like Hubble isn’t as straightforward as simply pointing the camera and clicking. Commercial cameras typically try to collect most of … Read more

ESO’s VLT Records A Beautiful Overlap of Spiral Galaxies

This image shows, top left, a pair of superimposed spiral galaxies, NGC 3314a and NGC 3314b, captured by ESO’s VLT Survey Telescope (VST) in a majestic cosmic dance. But don’t let the prospect fool you! These objects are not interacting. The two galaxies, located at a distance of between 117 and 140 million light years … Read more

Astronomers Discover What’s Killing Galaxies

Astronomers examining the nearby Universe with the help of the Atacama Large Millimeter / submillimeter Array (ALMA) have just completed the largest high-resolution star-forming fuel survey ever conducted in galaxy clusters. But, more importantly, they’re dealing with an ancient astrophysical mystery: what’s killing galaxies? The research, which provides the clearest evidence to date that extreme … Read more

Astronomers Finally Can Explain the Origin of Ultrafuzzy Galaxies

As the name suggests, ultra-diffuse galaxies, or UDGs, are dwarf galaxies whose stars are spread over a vast region, resulting in extremely low surface brightness, making them very difficult to detect. Several questions about UDGs remain unanswered: How did these dwarfs end up so extended? Are dark matter halos – the invisible matter halos that … Read more

Powerful Computational Simulations Show How Young, Disorderly Galaxies Grow and Evolve in the Universe

Using a supercomputer simulation, a research team at the University of Lund in Sweden has been able to track the development of a galaxy over 13.8 billion years. The study shows how, due to interstellar head-on collisions, young and chaotic galaxies over time mature into spiral galaxies such as the Milky Way. Right after the … Read more
