Decades of tension, debate, and determination have led to this moment, as the James Webb Space Telescope begins its million-mile journey into deep space.
“Hubble isn’t just a satellite; it’s about humanity’s quest for knowledge,” said astronaut and former NASA Chief Scientist, John M. Grunsfeld about the iconic space telescope. Looking at Hubble’s ground-breaking “Deep Field” images that show the most distant galaxies that can be observed in visible light leaves us feeling like something else is going about its business out there. Transformed Our View of Where We Are “We are born into the world like actors who are placed on a stage without a script. The Hubble Space Telescope has transformed our understanding of that stage...
NASA has not said what sort of error has hit the Earth-orbiting telescope, but space fans hope it will be back online soon.
Ancient galaxy clusters have been described as “the dark skeletons of the cosmos.” Astronomers at the Instituto de Astrofísica de Canarias (IAC) have found the most densely populated galaxy cluster in formation in the primitive universe. The researchers predict that this structure, among the largest astronomical objects in the Universe, which is at a distance of 12.5 billion light years from us, will have evolved becoming a cluster similar to the 1,300 galaxies of the Virgo Cluster, a neighbor of the Local Group of galaxies to which harbors our home galaxy, the Milky Way. The Dark Ske...
