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. OnContinuar Leyendo
Led by the University of Bern, an international research team has discovered a sub-Neptune exoplanet orbiting a red dwarf star. The discovery was also made thanks to observations performed by the SAINT-EX observatory in Mexico. SAINT-EX is run by a consortium including the Center for Space and Habitability (CSH) atContinuar Leyendo
For the first time ever, astronomers have imaged in real time the dramatic end to a red supergiant’s life — watching the massive star’s rapid self-destruction and final death throes before collapsing into a type II supernova. Evanston, Jan 07, 2022.- Led by researchers at Northwestern University and the UniversityContinuar Leyendo
The NASA/ESA/CSA James Webb Space Telescope team has fully deployed the spacecraft’s sunshield in space, a key milestone in preparing it for science operations. The sunshield – about the size of a tennis court at full size – was folded to fit inside the Ariane 5 rocket’s nose cone priorContinuar Leyendo
