NYTIMES (K. R. Callaway) - Massive Black Holes May Have Started as Little Red Dots
A new simulation suggests little red dots, unusually compact objects seen in photos from space, might be one stage in the evolution of black holes.

A peer-reviewed study warns that the moon's finite water ice reserves would run dry in as little as two years for a million-person city without recycling, a reality check aimed squarely at SpaceX's ambitious lunar colonization plans.

A peer-reviewed study warns that the moon's finite water ice reserves would run dry in as little as two years for a million-person city without recycling, a reality check aimed squarely at SpaceX's ambitious lunar colonization plans. Astronomers Martin Elvis and Jonathan McDowell published their findings in the journal Frontiers in Space Technologies, and the numbers cut against the grand visions of sprawling lunar metropolises that have dominated space policy conversations in Washington and Silicon Valley alike. Even under the most optimistic water estimates, a large settlement would face hard physical limits that no amount of federal spending or private-sector enthusiasm can wish away. The study lands at a moment when both NASA and…Open
Researchers have identified a speed demon at the heart of the Milky Way. This fast-moving star may yield insights into the black hole parked at the center of our galaxy.
The moon recedes about 1 inch per year from the Earth.
AI:Astronomers confirm that total solar eclipses are a temporary celestial phenomenon because the moon continues to recede from Earth at a rate of approximately one inch per year, meaning these spectacular events will eventually cease to occur on our planet.Open
Scientists have theorized that there may be two Betelgeuse stars for 100 years.
It’s the first potentially habitable world known to host an atmosphere, making it a lead contender in the search for life beyond our solar system.
In a stroke of luck, astronomers saw the comet C/2025 K1 (ATLAS) break into four or five fragments in November after it passed close to the sun.
A massive star in the nearby Andromeda galaxy has simply disappeared. Some astronomers believe that it's collapsed in on itself and formed a black hole.
