NASA’s Fermi Mission links nearby pulsar’s gamma-ray ‘halo’ to antimatter puzzle
NASA’s Fermi Gamma-ray Space Telescope has discovered a faint but sprawling glow of high-energy light around a nearby pulsar. If visible to the human eye, this gamma-ray “halo” would appear about 40 times bigger in the sky than a full…
Scientists find iron ‘snow’ in Earth’s core
The Earth’s inner core is hot, under immense pressure and snow-capped, according to new research that could help scientists better understand forces that affect the entire planet. The snow is made of tiny particles of iron – much heavier than…

The ‘cores’ of massive galaxies had already formed 1.5 billion years after the big bang
A distant galaxy more massive than our Milky Way – with more than a trillion stars – has revealed that the ‘cores’ of massive galaxies in the Universe had formed already 1.5 billion years after the Big Bang, about 1…
Astrophysics and AI may offer key to early dementia diagnosis
Crucial early diagnosis of dementia in general practice could improve thanks to a computer model designed in a collaboration between Brighton and Sussex Medical School (BSMS) and astrophysicists at the University of Sussex. Currently, only two-thirds of people with dementia…
NASA’s SDO sees new kind of magnetic explosion on sun
NASA’s Solar Dynamics Observatory has observed a magnetic explosion the likes of which have never been seen before. In the scorching upper reaches of the Sun’s atmosphere, a prominence — a large loop of material launched by an eruption on…
RIT and IAR observe pulsars for the first time from South America
Upgraded radio telescopes enable scientists to study pulsars from the southern hemisphere
Carbon cocoons surround growing galaxies far beyond previous beliefs
Researchers have discovered gigantic clouds of gaseous carbon spanning more than a radius of 30,000 light-years around young galaxies using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. This is the first confirmation that carbon atoms produced inside of stars…
