Nearly 15 years after the discovery of fast radio bursts (FRBs), the origin of the millisecond-long, deep-space cosmic explosions remains a mystery. Las Vegas, March 20, 2022.- That may soon change, thanks to the work of an international team of scientists — including UNLV astrophysicist Bing Zhang — which trackedContinuar Leyendo
París, March 15, 2022.- At 19:24 UTC on 11 March 2022, astronomer Krisztián Sárneczky discovered a bright and fast-moving new object in the sky using the 60cm Schmidt telescope at the Piszkéstető observatory, Hungary. He collected four observations in quick succession, and just 14 minutes later reported his findings toContinuar Leyendo
Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers at Leiden Observatory in the Netherlands have for the first time detected dimethyl ether in a planet-forming disc. With nine atoms, this is the largest molecule identified in such a disc to date. It is also a precursor of largerContinuar Leyendo
Scientists developed a neural network deep learning technique to extract hidden turbulent motion information from observations of the Sun. Tests on three different sets of simulation data showed that it is possible to infer the horizontal motion from data for the temperature and vertical motion. This technique will benefit solarContinuar Leyendo
A spectacular head-on collision between two galaxies, known as Arp 143, has fueled the unusual triangular-shaped star-formation frenzy as captured by the NASA/ESA Hubble Space Telescope. París, Feb 23, 2022.- The interacting galaxy duo Arp 143 contains the distorted, star-forming spiral galaxy NGC 2445, at right, along with its lessContinuar Leyendo
The European Southern Observatory’s Very Large Telescope Interferometer (ESO’s VLTI) has observed a cloud of cosmic dust at the centre of the galaxy Messier 77 that is hiding a supermassive black hole. The findings have confirmed predictions made around 30 years ago and are giving astronomers new insight into “activeContinuar Leyendo
Ten years ago this week, 13 February 2012, ESA opened a new era of independent access to space with the flawless inaugural flight of its small launcher Vega. Flying from Europe’s Spaceport in French Guiana, Vega has gone on to earn a reputation for precision and versatility in anticipation ofContinuar Leyendo
It has long been known that Mars once had oceans due in part to a protective magnetic field similar to Earth’s. However, the magnetic field disappeared, and new research may finally be able to explain why. Researchers recreated conditions expected in the core of Mars billions of years ago andContinuar Leyendo
Astronomers from Georgia State University have found an explanation for the strange occurrence of massive stars located far from their birthplace in the disk of our Milky Way Galaxy. Atlanta, Feb 03, 2022Stars more massive than the Sun have very hot cores that drive nuclear energy generation at very highContinuar Leyendo
París, Jan 10, 2022.- Today the James Webb Space Telescope team successfully fully deployed its iconic 6.4-metre, gold-coated primary mirror, completing the final stage of all major spacecraft deployments to prepare for science operations. “The successful unfolding of the Webb telescope has been a complex but impressive engineering masterpiece.
