1+ day, 7+ hour ago   (775+ words) New gravitational wave observatories could detect ancient black hole mergers and reveal how the first stars shaped the early universe. New generations of gravitational wave detectors could soon detect the hidden remnants of the universe’s first stars, according to a…...

2+ day, 14+ hour ago   (440+ words) Researchers found 84 so-called hypersoft X-ray sources in M101, Messier 31, and four elliptical galaxies Space scientists have revealed they've uncovered "mysterious objects" behaving in ways never witnessed before. Astronomers spotted them emitting remarkably low-energy X-rays while producing powerful bursts of ultraviolet radiation....

3+ day, 20+ hour ago   (1618+ words) What if a star simply disappeared from the sky? Astronomers have discovered a group of unusual white dwarf stars that suddenly became so heavily obscured that they appeared to vanish from view. The likely culprit isn't a disappearing star—but…...

5+ day, 13+ hour ago   (161+ words) Each of the quiet black holes we've discovered this way has a small stellar companion. This means that in the past these were asymmetrical binaries, meaning that one of the stars was much larger than the other. The remnants of…...

6+ day, 2+ hour ago   (214+ words) The Shillong Times Can the sun turn into a black hole? At the end of their lifespans, some massive stars collapse under their own weight until they turn into a black hole that sucks up everything around it. Birth, life…...

1+ week, 2+ day ago   (463+ words) A weird spacetime crystal has scientists looking at gravity in a whole new way, and the results are stranger than expected. Unlike the massive black holes found at the centers of galaxies or created by collapsing stars, these theoretical objects…...

1+ week, 3+ day ago   (502+ words) Astronomers have found a small, dark object that's so impossible to see, it can only be detected by the way its gravity distorts space. It's the lowest-mass dark object ever found in the Universe, and was discovered by using a…...

1+ week, 5+ day ago   (291+ words) Scientists have obtained new evidence for the existence of the first confirmed "starless" galaxy in history. The object known as Cloud 9 contains enormous reserves of hydrogen and dark matter but emits no light, according to a study published on the…...

1+ week, 6+ day ago   (265+ words) The study of black holes has been revolutionized by advancements in observational technology, including gravitational wave detectors and high-resolution telescopes. These tools have allowed astronomers to detect black holes indirectly through their interactions with surrounding matter, such as gas and…...

1+ week, 6+ day ago   (434+ words) Physicists have mathematically captured a bizarre “spacetime crystal” that can either dissolve or collapse into a microscopic black hole after only a tiny change in energy. Their breakthrough came from an unusual trick involving infinitely many dimensions, potentially giving researchers…...
