Hubble maps giant halo around Andromeda Galaxy

In a landmark study, scientists using NASA's Hubble Space Telescope have mapped the immense envelope of gas, called a halo, surrounding the Andromeda galaxy, our nearest large galactic neighbor. Scientists were surprised to find that this tenuous, nearly invisible halo... Continue Reading →

Neuralink…the future is weird

Elon Musk has showed off his company Neuralink’s brain-computer interface for the first time. In an announcement on 28 August, Neuralink unveiled prototypes of its device and showed off pigs with the devices implanted in their brains. The device resembles... Continue Reading →

Researchers track slowly splitting ‘dent’ in Earth’s magnetic field

A small but evolving dent in Earth's magnetic field can cause big headaches for satellites. Earth's magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America and the... Continue Reading →

Warming Greenland ice sheet passes point of no return

Nearly 40 years of satellite data from Greenland shows that glaciers on the island have shrunk so much that even if global warming were to stop today, the ice sheet would continue shrinking. The finding, published in the journal Nature Communications... Continue Reading →

Nanotubes in the eye that help us see

A new mechanism of blood redistribution that is essential for the proper functioning of the adult retina has just been discovered in vivo by researchers at the University of Montreal Hospital Research Centre (CRCHUM). Their study was published in Nature. "For... Continue Reading →

Candy-Colored Phobos

As of March 2020, our Mars Odyssey spacecraft has captured these six views of the Martian moon Phobos. The orbiter's infrared camera, the Thermal Emission Imaging System (THEMIS), is used to measure temperature variations that provide insight into the physical properties and... Continue Reading →

NGC 6814: Grand Design Spiral Galaxy from Hubble

In the center of this serene stellar swirl is likely a harrowing black-hole beast. The surrounding swirl sweeps around billions of stars which are highlighted by the brightest and bluest. The breadth and beauty of the display give the swirl... Continue Reading →

‘Black dwarf supernova’: Physicist calculates when the last supernova ever will happen

The end of the universe as we know it will not come with a bang. Most stars will very, very slowly fizzle as their temperatures fade to zero. "It will be a bit of a sad, lonely, cold place," said... Continue Reading →

Past evidence supports complete loss of Arctic sea-ice by 2035

A new study, published in the journal Nature Climate Change, supports predictions that the Arctic could be free of sea ice by 2035. High temperatures in the Arctic during the last interglacial -- the warm period around 127,000 years ago --... Continue Reading →
