| Cosmic flashes pinpointed to a surprising location in space Posted: 23 Feb 2022 10:35 AM PST Astronomers have been surprised by the closest source of mysterious flashes in the sky called fast radio bursts. Precision measurements with radio telescopes reveal that the bursts are made among old stars, and in a way that no one was expecting. The source of the flashes, in nearby spiral galaxy M 81, is the closest of its kind to Earth. |
| Colossal black holes locked in dance at heart of galaxy Posted: 23 Feb 2022 10:35 AM PST A sinusoidal light curve spanning 45 years points to the presence of orbiting supermassive black holes at the core of a distant galaxy. |
| Astronomers map mysterious element in space Posted: 23 Feb 2022 07:49 AM PST A research team has provided an important clue to the origin of the element Ytterbium in the Milky Way, by showing that the element largely originates from supernova explosions. The groundbreaking research also provides new opportunities for studying the evolution of our galaxy. |
| Galaxy collision creates 'space triangle' in new Hubble image Posted: 23 Feb 2022 05:58 AM PST A spectacular head-on collision between two galaxies fueled the unusual triangular-shaped star-birthing frenzy, as captured in a new image from NASA's Hubble Space Telescope. |
| 'Tatooine-like' exoplanet spotted by ground-based telescope Posted: 23 Feb 2022 05:58 AM PST A rare exoplanet which orbits around two stars at once has been detected using a ground-based telescope. The planet, called Kepler-16b, has so far only been seen using the Kepler space telescope. It orbits around two stars, with the two orbits also orbiting one another, forming a binary star system. |
| From the streets to the stratosphere: Clean driving technology enables cleaner rocket fuel Posted: 23 Feb 2022 05:57 AM PST A chemical used in electric vehicle batteries could also give us carbon-free fuel for space flight, according to new research. |
| Tiny probes could sail to outer planets with the help of low-power lasers Posted: 23 Feb 2022 05:54 AM PST Space travel can be agonizingly slow: For example, the New Horizons probe took almost 10 years to reach Pluto. Traveling to Proxima Centauri b, the closest habitable planet to Earth, would require thousands of years with even the biggest rockets. Now, researchers calculate that low-power lasers on Earth could launch and maneuver small probes equipped with silicon or boron nitride sails, propelling them to much faster speeds than rocket engines. |
| 290 million new city dwellers benefit China's climate balance Posted: 22 Feb 2022 10:52 AM PST Contrary to popular belief, China's massive emigration from rural areas to cities has been shown to have a positive effect on China's carbon stocks. Urbanization can even play a role in attaining climate neutrality. This is the conclusion of researchers based upon analyses of vast amounts of satellite data. |
