New image captures galaxy cluster emerging from cosmic web

The tumultuous evolution of a galaxy cluster captured close to its formation in the cosmic web
Composite image using MUSTANG-2, Chandra, and SDSS data. The faint red glow shows the hot gas at large radii. galaxies present in MUSTANG-2 and Chandra appear as point sources (in magenta) and density of the comparatively cool gas (in blue); galaxies in optical (SDSS) data are in the foreground.

An international team of astronomers using the National Science Foundation’s Green Bank Telescope (GBT) in Green Bank, West Virginia, and the NASA’s Chandra X-ray Observatory have captured a snapshot of a massive galaxy cluster, very close to the epoch when it began to emerge from the cosmic web.

When it comes to the Universe, there is more than meets the eye. Astronomers using the National Science Foundation’s Green Bank Telescope (GBT) have discovered a massive, previously unknown structure in our Galaxy. This discovery was so unexpected, additional observations were taken using the Green Bank Observatory’s 20-meter Telescope to confirm the data.

Qorvo, NRAO, and Green Bank Observatory Develop New Tech for Identifying Threats from Near-Earth Objects

Qorvo® (Nasdaq: QRVO), a leading provider of innovative radio frequency (RF) solutions that connect the world, today announced its Spatium® solid-state power amplifier (SSPA) technology will play a key role in a new planetary radar experiment using the National Science Foundation’s Green Bank Telescope (GBT). Planetary radar is instrumental in characterizing Near-Earth Objects (NEOs) by providing precision measurement of shape, rotation, position, and an estimate of composition.
