Bedtime Astronomy

Using ALMA, astronomers have detected sulfur-bearing molecules for the first time around the rare massive star HD 87643. The star’s chemically rich environment contains ten molecular species, including an unusual sulfur isotope imbalance linked to intense ultraviolet radiation.

The discovery offers new clues about how dying stars distribute the elements needed to build planets—and potentially life.

Astronomers have discovered S301, the fastest star ever observed in the Milky Way, racing around the supermassive black hole Sagittarius A* at an astonishing 25,000 km/s.

Its extreme orbit takes it closer to the black hole than any known star, offering scientists a rare opportunity to test Einstein’s relativity and measure the black hole’s spin.

Astronomers may have caught dark matter bending the light of a distant blazar. Observations of PKS 2233-148 revealed a sudden jet displacement and unusual gamma-ray flare, potentially caused by a passing clump of dark matter.

The finding could provide a rare glimpse of dark matter’s hidden structure while offering new clues about the origins of cosmic neutrinos and the universe’s most powerful particle accelerators.

Astronomers have discovered that dying radio galaxies remain active long after their black hole jets shut down—but for far less time than previously thought.

These faint remnants typically survive for just 8–42 million years, offering new clues about the intermittent lives of supermassive black holes and the evolution of galaxies across cosmic time.

The James Webb Space Telescope may have identified a bizarre cosmic object known as a black hole star—a compact, extremely luminous structure containing a massive black hole surrounded by a dense hydrogen envelope.

The discovery could explain the mysterious “little red dots” seen in the early universe and offer new clues about how the first black holes and galaxies formed.
