Indian scientists map Milky Way’s dusty veil using 6,000 star clusters

Astronomers from the Aryabhatta Research Institute of Observational Sciences (ARIES) have created a detailed map of cosmic dust in the Milky Way, using data from over 6,000 open star clusters. The study offers fresh insights into how interstellar dust is distributed across the galaxy and could help identify regions where new stars are likely to form. The research, led by Dr. Y.C. Joshi, shows that the dust does not lie flat along the Milky Way’s central plane but forms a thin, wavy layer know...

Astronomers scrutinize a star behaving unlike any other

Astronomers have spotted a star acting unlike any other ever observed as it unleashes a curious combination of radio waves and X-rays, pegging it as an exotic member of a class of celestial objects first identified only three years ago. It is located in the Milky Way galaxy about 15,000 light-years from Earth in the direction of the constellation Scutum, flashing every 44 minutes in both radio waves and X-ray emissions. A light-year is the distance light travels in a year, 5.9 trillion miles (9...

Webb Telescope provides unprecedented view of our Milky Way’s supermassive black hole

NASA's James Webb Space Telescope is providing the best look yet at the chaotic events unfolding around the supermassive black hole at the center of our Milky Way galaxy, observing a steady flickering of light punctuated by occasional bright flares as material is drawn inward by its enormous gravitational pull. Webb, which was launched in 2021 and began collecting data in 2022, is enabling astronomers to observe the region around the black hole - called Sagittarius A*, or Sgr A* - for extended ...

Webb telescope reveals rapid growth of primordial black hole

At the heart of our Milky Way galaxy lurks a supermassive black hole about four million times the mass of the sun, called Sagittarius A*. In fact, these objects, which increase in mass over time by eating material that wanders too close, reside at the center of most galaxies. But since NASA's James Webb Space Telescope came online in 2022, astronomers have been surprised to find supermassive black holes inhabiting the early universe - earlier than they had thought possible considering the time ...

Rotten eggs chemical detected on Jupiter-like alien planet

The planet known as HD 189733b, discovered in 2005, already had a reputation as a rather extreme place, a scorching hot gas giant a bit larger than Jupiter that is a striking cobalt blue color and has molten glass rain that blows sideways in its fierce atmospheric winds. So how can you top that? Add hydrogen sulfide, the chemical compound behind the stench of rotten eggs. Researchers said on Monday new data from the James Webb Space Telescope is giving a fuller picture of HD 189733b, already am...

Scientists witness a dormant supermassive black hole roar to life

At the center of the Milky Way galaxy resides a supermassive black hole four million times the mass of our sun called Sagittarius A* that some scientists have called a gentle giant because of its quiescence. But someday it could become a beast. Researchers said on Tuesday they have observed in real time a dramatic brightening at the heart of another galaxy apparently caused by a supermassive black hole awakening from dormancy and beginning to gorge itself with nearby material. It marks the firs...
