Astronomers have recently raised concerns about the impact of satellite mega-constellations on scientific research. To better understand the effect these constellations could have on astronomical observations, ESO commissioned a scientific study of their impact, focusing on observations with ESO telescopes...

Some stars explode in slow motion. Rare, massive Wolf-Rayet stars are so tumultuous and hot that they are slowly disintegrating right before our telescopes. Glowing gas globs each typically over 30 times more massive than the Earth are being expelled by violent stellar winds. Wolf-Rayet star WR... Continue Reading →
International blood pressure guidelines may require review, according to new research that found a link between low blood pressure and higher mortality rates. A largescale study led by the University of Exeter, published in Age and Ageing and funded by NIHR, analysed... Continue Reading →
The conclusions of a study carried out by Víctor Costumero, as the first author, Marco Calabria and Albert Costa (died in 2018), members of the Speech Production and Bilingualism (SPB) group at the Cognition and Brain Center (CBC) of the... Continue Reading →
While turbulence is everywhere – from planes to white water rafting and whirlpools in the bathtub – it’s one of the least understood phenomena in physics. The image above is of vortex cannons firing in a 75-gallon aquarium to produce... Continue Reading →
If you like slow dances, then this may be one for you. A single turn in this dance takes several hundred million years. Two galaxies, NGC 5394 and NGC 5395, slowly whirl about each other in a gravitational interaction that sets off a flourish... Continue Reading →
The Earth of 3.2 billion years ago was a "water world" of submerged continents, geologists say after analyzing oxygen isotope data from ancient ocean crust that's now exposed on land in Australia. And that could have major implications on the... Continue Reading →
Blown by fast winds from a hot, massive star, this cosmic bubble is much larger than the dolphin it appears to be. Cataloged as Sharpless 2-308 it lies some 5,200 light-years away toward the constellation of the Big Dog (Canis Major) and... Continue Reading →
Rats on a high sugar diet during pregnancy have altered levels of sex steroid hormones (e.g. progesterone) and dopamine in their brains, which may lead to behavioural changes that can affect care of offspring and motivation, as well as increasing... Continue Reading →
