Explorando os Enigmas do Superuniverso
Advertisement A potentially hazardous asteroid (PHA), estimated to be around 300 meters in size, is expected to pass by the Earth on Wednesday, May 9. The space rock, designated 2008 TZ3, will fly by our planet at 10:06 UTC at a safe distance of about 6.5 lunar distances (LD), what corresponds to 2.5 million kilometers. […]
Advertisement Two astronomers from the University of Madrid have just published a paper which ‘confirms’ fears that a star called Gliese 710 will come unnervingly close to our solar system. Although this will not be a head-on collision, the prodigal sun will scorch through the Oort cloud – a ring of icy objects that surround […]
Advertisement Sometimes the most amazing discoveries can happen just by chance. Case in point: an international team of astronomers accidentally photographed what they think is a planet in the process of growing bigger, 600 light-years away. The star in question is a binary called CS Cha, located in a star-forming region in the southern constellation of Chamaeleon. […]
Advertisement A groundbreaking experiment in physics has for the first time provided a precise measurement of a force between electrons and protons called the weak nuclear force. The value 0.0719 (give or take 0.0045) won’t mean much to most of us, but the way they did it makes way for some exciting possibilities for pushing […]
Advertisement Proving Albert Einstein wrong is something that only a small number of scientists can claim to have done but now, more than 100,000 gamers can join that exclusive club and enjoy the smugness that comes with it. In 2016, scientists from around the world led by the Institute of Photonic Sciences in Barcelona (ICFO) asked people to […]
Advertisement Our Milky Way galaxy contains tens of billions of potentially habitable planets, but we have no idea whether we’re alone. For now Earth is the only world known to harbor life, and among all the living things on our planet we assume Homo sapiens is the only species ever to have developed advanced technology. But maybe that’s assuming […]
Advertisement Those wishing to honor the theoretical physicist, who died in March aged 76, can apply via a public ballot. Applicants need to give their birth date – which can be any day up to 31 December 2038. Prof Hawking’s foundation said the possibility of time travel had not been disproven and could not be excluded. […]
Advertisement Astronomers have discovered a record-breaking star system. It’s called IGR J17062-6143, and it’s a very compact binary, where one of the stars is a rapidly spinning, superdense neutron star called an X-ray pulsar. The two stars take just 38 minutes to orbit each other. That’s the fastest orbital period of any X-ray pulsar binary […]
Advertisement Announcement alert! NASA is preparing to give us some big news about Jupiter’s moon Europa, and it could have some major implications for the search for life. On Monday May 14 at 1pm EDT (5pm GMT), the agency will hold a briefing “to discuss the latest analysis of Jupiter’s moon Europa and its status as one […]
Two years after the Starshot Breakthrough Initiative was launched with the aim of sending an object towards our nearest stellar neighbour, we’re still left staring at the heavens dreaming of the possibility. A team of materials scientists has taken a more sober look at the current state of technology and listed what we need to […]
