Citando:
"The Hayabusa2 spacecraft last week made history after it briefly touched down on the near-Earth asteroid Ryugu. The incredible technological feat could provide to understanding the origins of life on Earth. But the latest image released by Japan Aerospace Exploration Agency (JAXA) shows an apparently inexplicable smudge on the asteroid’s surface."

A música e o efeito no cérebro

https://www.technologynetworks.com/neuroscience/news/how-music-activates-our-brains-reward-center-315391
Citando:
"If you love it when a musician strikes that unexpected but perfect chord, you are not alone. New research shows the musically unexpected activates the reward center of our brains, and makes us learn about the music as we listen.

Researchers led by Ben Gold, a PhD candidate in the lab of Robert Zatorre at The Neuro (Montreal Neurological Institute and Hospital), of McGill University, put 20 volunteers through a musical reward learning task. Each participant chose a color, then a direction. Each choice came with a certain probability of leading to either a consonant, pleasurable, musical excerpt or a dissonant, unpleasurable one. Over time the subjects learned which choices were more likely to produce both consonant and dissonant music. The test was designed to create an expectation of either musical enjoyment or dissatisfaction. Subjects performed this task while their brain activity was measured with functional magnetic resonance imaging (MRI)."

Nova galáxia descoberta

http://sci.esa.int/hubble/61075-hubble-fortuitously-discovers-a-new-galaxy-in-the-cosmic-neighbourhood-heic1903/

Citando:
"An international team of astronomers recently used the NASA/ESA Hubble Space Telescope to study white dwarf stars within the globular cluster NGC 6752. The aim of their observations was to use these stars to measure the age of the globular cluster, but in the process they made an unexpected discovery.

In the outer fringes of the area observed with Hubble's Advanced Camera for Surveys a compact collection of stars was visible. After a careful analysis of their brightnesses and temperatures, the astronomers concluded that these stars did not belong to the cluster – which is part of the Milky Way – but rather they are millions of light-years more distant.

Our newly discovered cosmic neighbour, nicknamed Bedin I by the astronomers, is a modestly sized, elongated galaxy. It measures only around 3000 light-years at its greatest extent – a fraction of the size of the Milky Way. Not only is it tiny, but it is also incredibly faint. These properties led astronomers to classify it as a dwarf spheroidal galaxy."
