NASA's NuSTAR (Nuclear Spectroscopic Telescope Array) space telescope was successfully launched into space on Wednesday. Thus began his mission to unveil the secrets of black holes and other exotic objects in the universe.
It is not black, as we usually think. In fact, when the universe was young - 2.5 billion years ago - it was predominantly blue, but over time it has turned beige, as Karl Glazebrook and Ivan Baldry, researchers at John University, demonstrated a few years ago. Hopkins (USA), after analyzing the light of 200,000 galaxies. The color has been dubbed "cosmic latte", although the name "unibeige" (universe + beige) was also considered, and its value in the hexadecimal RGB system is # FFF8E7.
A spectrometer designed by astronomers at the University of California (USA) will allow scientists to study the first galaxies that formed in the Universe.
For the first time in history, scientists at the University of Southampton (UK) have used physics and mathematics to recreate the natural sounds of other worlds, from lightning on Venus, to the winds on Mars and the crunching of ice from the volcanoes of Titan, the moon of Saturn. In addition, they have modeled the effects of different atmospheres, pressures and temperatures on the human voice on Mars, Venus and Titan.
A group of French researchers has carried out the first computer simulation of the structure of the entire observable universe, from the Big Bang to the present day. These simulations allow us to see how no less than 550,000 million particles have evolved.
Mario Pérez, an astrophysicist with the NASA Scientific Program, takes his iPhone out of his pocket and checks application 1 that shows in real time the number of extrasolar planets identified. "We use this app here to keep up to date on the discoveries made by both ground-based telescopes and the only two space probes dedicated to looking for exoplanets -Kepler and Corot-. You have to keep up to date, because the findings literally increase from week to week ". This Chilean is in charge of the various NASA missions in charge of discovering exoplanets, those that are outside the Solar System.
It is one of the questions that the mission of ESA Planck tries to answer. At an international conference in Bologna, Italy, attended by astronomers from around the world, its leaders have unveiled the first carbon monoxide distribution map that covers the entire sky. Carbon monoxide is an ingredient in cold clouds in the Milky Way and other galaxies. These clouds, mainly made up of hydrogen molecules, constitute the reservoirs from which stars are born.
Why is the universe magnetized? This is a question that scientists have been asking for decades. Now an international team of researchers has found the answer, their findings published in the January 26 issue of the journal Nature.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
