Take a Summer Cosmic Road Trip With NASA’s Chandra and Webb
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…

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…
Read MoreAstronomers Find Confounding Cone Shape in Cluster Collision
Galaxy clusters take eons to collide. Now, astronomers have caught a pair of merging clusters in an in-between stage never seen before. The post Astronomers Find Confounding Cone Shape in Cluster Collision appeared first on Sky & Telescope.
Read MoreLost & Found: Milky Way-size “Orphan Cloud”
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.
Read MoreTwisters in the Cosmic Web
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.
