Astrophysics

This artist's concept shows what happened when two massive clusters of galaxies, collectively known as MACS J0018.5, collided: The dark matter in the galaxy clusters (blue) sailed ahead of the associated clouds of hot gas, or normal matter (orange). Both dark matter and normal matter feel the pull of gravity, but only the normal matter experiences additional effects like shocks and turbulence that slow it down during collisions.

Dark matter flies ahead of normal matter in mega galaxy cluster collision

Simulation of the light emitted by a supermassive black hole binary system where the surrounding gas is optically thin (transparent). Viewed from 0 degrees inclination, or directly above the plane of the disk. The emitted light represents all wavelengths.

Astrophysicists uncover supermassive black hole/dark matter connection in solving the ‘final parsec problem’

Terzan 5, located in the constellation Sagittarius, is a crowded globular cluster home to hundreds of thousands of stars.Ten unusual and exotic pulsars were recently discovered by an international team of astronomers from the U.S. National Science Foundation National Radio Astronomy Observatory, the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) (AEI), and the Max Planck Institute for Radio Astronomy

Here's a clearer version of the image caption: Colored map of the PJ308-21 system showing gas emissions: - Hydrogen: Red and blue - Oxygen: Green The central quasar's light has been masked out. Color variations in the quasar's host galaxy and its companions indicate different gas properties in each region.

Star clusters observed within a galaxy in the early Universe for the first time

Artist's impression of a microlensing event caused by a black hole observed from Earth toward the Large Magellanic Cloud. The light of a background star located in the LMC is bent by a putative primordial black hole (lens) in the Galactic halo and magnified when observed from the Earth. Microlensing causes very characteristic variation of brightness of the background star, enabling the determination of the lens's mass and distance. Credit: J. Skowron / OGLE.

For a brief period of time millions of years ago, Earth may have been plunged out of the sun’s protective plasma shield, called the heliosphere, which is depicted here as the dark gray bubble over the backdrop of interstellar space. According to new research, this could have exposed Earth to high levels of radiation and influenced the climate. Photo courtesy of Opher, et al., Nature Astronomy
