Cosmic Road Trip: four distinct composite images from NASA’s Chandra X-ray Observatory and the James Webb Space Telescope, presented in a two-by-two grid, Rho Ophiuchi at lower right, the heart of the Orion Nebula at upper right, the galaxy NGC 3627 at lower left and the galaxy cluster MACS J0416. X-ray: NASA/CXC/SAO; Optical/Infrared: (Hubble) NASA/ESA/STScI; IR: (JWST) NASA/ESA/CSA/STScI It’s time to take a cosmic road trip using light as the highway and visit four stunning destinations across space. The vehicles for this space get-away are NASA’s Chandra X-ray Observatory and…

Stellar Beads on a String
Galaxy cluster SDSS J1531+3414 X-ray: NASA/CXC/SAO/O. Omoruyi et al.; Optical: NASA/ESA/STScI/G. Tremblay et al.; Radio: ASTRON/LOFAR; Image Processing: NASA/CXC/SAO/N. Wolk Astronomers have discovered one of the most powerful eruptions from a black hole ever recorded in the system known as SDSS J1531+3414 (SDSS J1531 for short). As explained in our press release, this mega-explosion billions of years ago may help explain the formation of a striking pattern of star clusters around two massive galaxies, resembling “beads on a string.” SDSS J1531 is a massive galaxy cluster containing hundreds of individual galaxies and huge reservoirs of hot gas and dark…

Astronomers have found a giant gas cloud, likely stripped from its parent galaxy long ago, in a cluster 330 million light-years away. The post Lost & Found: Milky Way-size "Orphan Cloud" appeared first on Sky & Telescope.

Astronomers have found that the largest structures in the universe spin, making twister-like strings of galaxies and dark matter in the cosmic web. The post Twisters in the Cosmic Web appeared first on Sky & Telescope.
