Perspective of the Milky Way galaxy as seen from Earth. Credit: ESO/S An animated dive into the dusty Milky Way reveals the outline of our galaxy that formed as we looked further away from Earth. Based on new data from an interactive tool that leverages data from the European Space Agency’s Gaia mission and other space science datasets, astronomers have created an animation to model the dust in the Milky Way. The work was presented this week at the National Astronomy Meeting (NAM 2022) at the University of Warwick and published in Astronomy & Astrophysics . The animation shows a visible cumulative dust buildup from Earth’s local environment up to ~13,000 light-years towards the galactic center—about 10% of the total distance across the Milky Way. Nearby, dust swirls around but, further away, the concentration of dust along the galactic plane becomes apparent. Two “windows”, one above and one below the galactic plane, were also revealed.

This image shows the center of our Milky Way galaxy. It shows the position of stars in the so-called S star cluster, a small group of high-speed stars orbiting our Milky Way’s central black hole (at the black cross). Speedy star S4716 has set a new record as the fastest known of all these stars. Image via Peissker et al. Fast star orbiting the Milky Way’s black hole Scientists in Europe said on July 5, 2022 that they had found the fastest star known to orbit a black hole. And not just any black hole… it orbits Sagittarius A*, the giant black hole at the center of our Milky Way galaxy. Our central black hole weighs about 4 million times the mass of our sun. The newly discovered star is called S4716. It reaches an orbital speed of 5,000 miles per second (8,000 kps) around the black hole, or about 5,000 times faster than the fastest fighter jet. Imagine seeing star – a huge ball of turbulent gas that glows on its own – shooting at this speed! By the way, on the other hand, ou

A newly discovered star, now called S4716, is moving at 5,000 miles (8,000 km) per second around the black hole at the center of our galaxy, the Milky Way, space.com reported. The vast expanse of our universe means that astronomers are always discovering something they’ve never seen before. Earlier this week, astronomers spotted two asteroids the size of a bus heading for Earth, which will pass just a quarter of the distance that separates the Moon from us. In addition to asteroids, our galaxy is also attracting the attention of astronomers looking for signs of other planets that support life. Right at the center of the Milky Way, there is a supermassive black hole dubbed Sagittarius A* or Sgr A* and S4716 orbits this black hole at high speed. What we know about S4716 From observations made so far, we know that at 5,000 miles (8,000 km) per second or 18 million miles (29 million km) per hour, S4716 is the fastest star orbiting Sgr A*. It completes an orbit around a black hole with

A team of researchers say they have found some of the building blocks of RNA in a molecular cloud close to the center of the Milky Way. The discovery has implications for theories about how life began on Earth – and perhaps elsewhere. The molecular cloud is named G+0.693-0.027. A team of astrophysicists, astrobiologists and chemists conducted a cloud survey using two telescopes in Spain to uncover chemical details. Ribonucleic acid (RNA) is a molecule present in all living cells that behaves similarly to DNA, although it is single-stranded. There is evidence that RNA could precede DNA, based on laboratory observations of ribosomes, which are composed of RNA. However, whether ancient RNA could start life or not, is another matter. The team recently discovered several organic molecules in the cloud that are part of a group called nitriles, which may have been important in producing RNA in the early universe; The team’s results were published today in Frontiers in Astronomy and Space
