This artist’s concept portrays the supermassive black hole at the center of the Milky Way galaxy, known as Sagittarius A* (A-star). It’s surrounded by a swirling accretion disk of hot gas. The black hole’s gravity bends light from the far side of the disk, making it appear to wrap above and below the black hole.<br />Several flaring hot spots that resemble solar flares, but on a more energetic scale, are seen in the disk. NASA’s James Webb Space Telescope has detected both bright flares and fainter flickers coming from Sagittarius A*. The flickers are so rapid they must originate very close to the black hole.

Turtle hatchlings of the endangered loggerhead (Caretta caretta) species head to the ocean after being released by conservationists who protect them from predators in a nursery on El Puerto beach, in the fishing village of La Sabana, La Guaira State, Venezuela, on July 29, 2022. The Ministry of Popular Power for Eco-Socialism (Minec), together with volunteers and naturalists, are developing a sea turtle conservation project aimed at protecting endangered species by collecting their eggs to nest them in a hatchery and releasing them into the sea after birth.

This artist’s illustration shows the largest radio jet ever found in the early Universe. The jet was first identified using the international Low Frequency Array (LOFAR) Telescope, a network of radio telescopes throughout Europe. Follow-up observations in the near-infrared with the Gemini Near-Infrared Spectrograph (GNIRS), and in the optical with the Hobby Eberly Telescope, were obtained to paint a complete picture of the radio jet and the quasar producing it. GNIRS is mounted on the Gemini North telescope, one half of the International Gemini Observatory, funded in part by the U.S. National Science Foundation and operated by NSF NOIRLab. Historically, such large radio jets have remained elusive in the distant Universe. With these observations, astronomers have valuable new insights into when the first jets formed in the Universe and how they impacted the evolution of galaxies.

TOPSHOT - The Artemis I unmanned lunar rocket sits on the launch pad at the Kennedy Space Center on September 2, 2022. NASA will make a second attempt to launch its powerful new Moon rocket on September 3, after scrubbing a test flight earlier in the week. The highly anticipated uncrewed mission will bring the US a step closer to returning astronauts to the Moon five decades after humans last walked on the lunar surface.
