Sometimes you just have to stand back in awe at the beauty of the Universe – and that’s absolutely the case with this image from the National Radio Astronomy Observatory (NRAO), which captures the side view of a spiral galaxy know as the Whale Galaxy.
But if you look closer, the stunning picture also shows something else: the magnetic ‘ropes’ around the edges of the galaxy’s disc.
These filaments, like cosmic strands of hair, show the galaxy’s magnetic field extending into its halo.
Old U.S. spy satellite images of the Middle East have unearthed a stunning discovery: the world’s first city, Tell Brak – 4,000 years older than the Great Pyramids. From the Series: The Life of Earth: The Age of Humans http://bit.ly/32oNmi8
Samsung’s Galaxy S20 Ultra might have over-the-top specs with 16GB of RAM and a ridiculous variety of cameras.
Real Mars research at the end of the world.
The end of the world serves as host to an international group of researchers trying to understand Mars’ Poles.
Brain cancer remains challenging to diagnose, due to nonspecific symptoms and a lack of cost-effective tests. A new blood test that uses attenuated total reflection (ATR)-Fourier transform infrared (FTIR) spectroscopy in conjunction with machine learning technology, may help advance the detection of brain cancer.
The patented technology, developed by a team at the University of Strathclyde, uses infrared light to produce a “bio-signature” of a blood sample and applies artificial intelligence to check for the signs of cancer.
The research is published in Nature Communications in a paper titled, “Development of high-throughput ATR-FTIR technology for rapid triage of brain cancer.”
Japanese billionaire Yusaku Maezawa’s search for a girlfriend to join him on a voyage around the moon will be the subject of a new documentary program, in the latest attention-grabbing stunt by the entrepreneur.
44-year-old Maezawa, who sold his online fashion retailer Zozo Inc to SoftBank Group Corp, is seeking single females aged over 20 for the show, which will be shown on streaming service AbemaTV.

Electric thrusters for spacecraft are increasingly shrinking, and could prove key for new space missions. And, according to two novel space tech companies, Phase Four and Accion Systems, they might even go interplanetary.
Conventional rockets that rely on chemical reactions “are a great way to generate a lot of thrust, but they are very inefficient when it comes to generating thrust given the amount of propellant they carry,” Simon Halpern, founder and CEO of space propulsion company Phase Four in El Segundo, California, told Space.com. “That’s why launching even a small satellite requires a gigantic multistory rocket.”
Scientists have explored a variety of alternatives to chemical rockets over the years. One is electric propulsion, which generates thrust by using electricity to accelerate electrically charged propellants away from a spacecraft. [Wild Ideas for Superfast Space Propulsion].
Researchers foresee myriad benefits for humanity, but also acknowledge ethical issues.
