"Researchers using two of humanity’s most powerful observatories — NASA’s James Webb and Hubble Space Telescopes — have definitively shown that Terzan 5 is not a globular star cluster as it was once classified, offering new insight into how galaxies like our own form and evolve over time."

"The aftermath of a supernova, a stellar explosion, is usually a slowly fading cloud of hot gas. So when astronomers pointed NASA's Chandra X-ray Observatory at the nearby galaxy Messier 83 (M83), they did not expect to find a population of supernova remnants, or the debris from these explosions, showing dramatic changes in their brightness. The new results were presented at the American Astronomical Society meeting in Pasadena, California, and published in The Astrophysical Journal."

Over a 14-year period from 2000 to 2014, astronomers pointed NASA’s X-ray observatory at the M83 galaxy. They discovered that about half of the X-ray sources

"On the morning of 1 July 2025, the ATLAS survey telescope at Río Hurtado in Chile detected an unusual moving point of light against the background stars."

On the morning of 1 July 2025, the ATLAS survey telescope at Río Hurtado in Chile detected an unusual moving point of light against the background stars. Within a few hours, follow-up observations from other telescopes had confirmed the object’s trajectory: this was not a solar-system comet on a ...

"Every 26 months, the orbits of Earth and Mars align in a particular geometric configuration that allows spacecraft to travel between them with the lowest possible fuel expenditure."

Every 26 months, the orbits of Earth and Mars align in a particular geometric configuration that allows spacecraft to travel between them with the lowest possible fuel expenditure. The window lasts approximately one month. Miss it, and the next opportunity is more than two years away. The next such....

"NASA on Tuesday revealed the four astronauts who will join the next Artemis mission — a key, two-week flight that will aim to test out various technologies considered vital to putting astronauts back on the surface of the moon for the first time in more than 50 years."

NASA announced the four astronauts that will join the next Artemis mission — a test flight vital to putting astronauts back on the surface of the moon for the first time in more than 50 years.

"A new study from Caltech's Jim Fuller, professor of theoretical astrophysics, proposes a new model of the final death throes of Sun-like stars that shows how escaping mass from the stars' surfaces leads to a series of little kicks."

New model describes how an aging star's outer shell ejections push it in opposite direction.

"For decades, scientists have searched for a fifth fundamental force of nature that can explain mysterious aspects of the universe such as dark energy and dark matter."

"The first step isn't technical, but mental: convincing yourself that a possible path actually exists."

"Scientists may have finally seen the sun telegraph an eruption hours before it happened — and the one caught was one of our star's most powerful explosions."

"There's very few that reach that amount of power."

"Ten days ago, in a moment of very high drama in orbit, NASA directed its astronauts living on the International Space Station to briefly seek emergency refuge in a Crew Dragon spacecraft."

This has been a persistent, behind-the-scenes dispute between NASA and Roscosmos.
