"If these results are confirmed, it would mark a major paradigm shift in cosmology since the discovery of dark energy 27 years ago."
Astronomy would be a lot easier if there were no clouds of gas and dust in space. There'd be no need for telescopes with the abilty to see through these thick veils. Alas, space is not only full of things we want to see, but full of things that get in the way.

The near-full moon shines close to the Pleiades open star cluster early on Nov. 6
"By reproducing relativistic plasma conditions in the lab, we can measure processes that shape the evolution of cosmic jets and better understand the origin of magnetic fields in intergalactic space."
The Moon, Earth's only natural satellite, is a fascinating celestial body. Here are some interesting facts about its characteristics and history.
A United Launch Alliance Atlas V rocket will launch the 13,000-pound (5,900 kilograms) ViaSat-3 F2 satellite to orbit today (Nov. 5), and you can watch the action live.
The astronauts of China's three-person Shenzhou 20 mission will wait a little longer before returning to Earth, after a suspected debris impact on their spacecraft.
Astrophotographer Mark Johnstron captured a mesmerizing cloud of hydrogen plasma dancing above the sun's limb in this breathtaking video.
Under the untouched darkness of Chile's Atacama Desert, the European Southern Observatory's Very Large Telescope stands beneath an arching Milky Way.
Rocket Lab will launch its sixth mission for the Japanese Earth-imaging company iQPS this afternoon (Nov. 5), and you can watch the action live.
Observing obstacles plague all amateur astronomers, but when the chance arises, we can still embrace unanticipated wonder.
November's full supermoon occurs as the moon draws close to Earth in its 27-day orbit.
The back-to-back eruptions caused radio blackouts across two hemispheres as the active sunspots turn to face Earth.
Don't miss 2025's closest full moon with this free livestream from Italy with the Virtual Telescope Project. The livestream will begin at 2 p.m. EST (1900 GMT)
An ultra-high-resolution instrument on board NASA's $10 billion James Webb Space Telescope has been suffering from blurry vision. AI helped fix the problem.

This shimmering view of interstellar gas and dust was captured by the European Space Agency’s Euclid space telescope. The nebula is part of a so-called dark cloud, named LDN 1641. It sits at about 1300 light-years from Earth, within a sprawling complex of dusty gas clouds where stars are being formed, in the constellation of Orion.
In 1949, famed mathematician and physicist John von Neumann delivered a series of addresses at the University of Illinois, where he introduced the concept of "universal constructor." The theory was further detailed in the 1966 book, Theory of Self-Reproducing Automata, a collection of von Neumann's writings compiled and completed by a colleague after his death. In the years that followed, scientists engaged in the Search for Extraterrestrial Intelligence (SETI) considered how advanced civilizations could rely on self-replicating probes to explore the galaxy.
President Donald Trump has tapped billionaire private astronaut Jared Isaacman to be NASA chief, five months after pulling his nomination for the same post.

SpaceX is preparing to launch its first batch of Starlink satellites in November. The company has at least eight such missions planned before the Thanksgiving Day holiday.
