The size and age of the universe, as well as how fast it is expanding, has been confirmed with a new, precise method that uses galaxies as lenses to look at other galaxies. The new measurement confirmed the age of the universe as 13.75 billion years old, to within 170 million years, and also confirmed the strength of dark energy, which is responsible for the accelerating expansion of the universe. When looking out at the cosmos, it can be difficult for scientists to distinguish between a very bright light far away and a dimmer source much closer to Earth. To circumvent this problem, a team of researchers used a technique called gravitational lensing to measure the distances light traveled from a bright, active galaxy to the Earth along different paths, along with data from the Hubble Space Telescope. Researchers can use the observations to infer not just how far away the galaxy lies but also the overall scale of the universe and some details of its expansion.

Esa es la conclusión del nuevo análisis de los datos que hace una década obtuvo la sonda Galileo. Gagarin, 50 años después. Astroseti : Astronomía, Astrobiología, Astronautica y SETI
Universe Today The Falcon 9 and Dragon capsule stand ready for launch prior to the detection of a helium leak in one of the engines forcing a scrub of the launch attempt on April 14. 2014 – now reset to April 18, 2014. Credit: nasatech.net NASA and SpaceX are marching forward towards a Friday, April 18 liftoff attempt for the Falcon 9 rocket sending a commercial Dragon cargo craft on the company’s third resupply mission to the International Space Station following the scrubbed launch attempt on Monday, April 14 – forced by the discovery of a Helium gas leak inside the rocket during the latter stages of the countdown. An on time blastoff of the upgraded Falcon 9 sets the stage for an Easter Sunday rendezvous and berthing of the Dragon resupply spacecraft at the massive orbiting outpost packed with almost 5000 pounds of science experiments and supplies for the six person crew. However the weather prognosis is rather [click to continue…]

Journals Online - Browse Journals By RSS/Atom Feeds What are RSS and Atom feeds? RSS and Atom news feeds are computer-readable files that summarise new content as it appears on a website. (RSS and Atom are just two different formats that do basically the same thing.) Each feed includes a heading, a brief description of the new content and a link through to the website.
