The aliens came on Oct. 19, 2017. That was the day telescopes picked up a strange object with an odd, elongated shape that moved like a comet — but had no apparent tail. The object, which baffled astronomers and led some to claim it could be a spacecraft sent by intelligent life, was named ‘Oumuamua, ...
Research from the University of Sheffield has found that the chance of finding Earth-like planets in their early stages of formation is much higher than previously thought. The team studied groups of young stars in the Milky Way to see if these groups were typical compared to theories and previous observations in other star-forming regions ...
The 250-million-year-old cracks in the seafloor feed the greenhouse gas methane into giant craters in the Barents Sea. More than 100 craters, presently expelling enormous amounts of greenhouse gas into the ocean, are found in the area. A CAGE paper published in Science in 2017 described hundreds of massive, kilometer-wide, craters on the ocean floor ...
New research that “fills in the blanks” on what ancient Papuan New Guineans ate, and how they processed food, has ended decades-long speculation on tool use and food stables in the highlands of PNG several thousand years ago. A recent research report detailing findings from the “Joe’s Garden” site in the Ivane Valley in the ...
A Bristol academic has achieved a milestone in statistical/mathematical physics by solving a 100-year-old physics problem — the discrete diffusion equation in finite space. The long-sought-after solution could be used to accurately predict encounter and transmission probability between individuals in a closed environment, without the need for time-consuming computer simulations. This discovery will help predict ...
Active galactic nuclei (AGNs) play a major role in galaxy evolution. Astronomers from SRON and RuG have now used a record sample of galaxies to confirm that galaxy mergers have a positive effect on igniting AGNs. They were able to compile about 10 times more pictures of merging galaxies than previous studies by using a ...
A new study reveals the Chicxulub impact crater may have harbored a vast and long-lived hydrothermal system after the catastrophic impact event linked to the dinosaurs‘ demise 66 million years ago. The Chicxulub impact crater, roughly 180 kilometers in diameter, is the best-preserved large impact structure on Earth and a target for the exploration of ...
On May 29, 2020, a family of sunspots — dark spots that freckle the face of the Sun, representing areas of complex magnetic fields — sported the biggest solar flare since October 2017. Although the sunspots are not yet visible (they will soon rotate into view over the left limb of the Sun), NASA spacecraft ...
Astronomers using NASA’s Hubble Space Telescope are finding that planet formation is tough in the rough-and-tumble central region of the massive, crowded star cluster Westerlund 2. Located 20,000 light-years away, Westerlund 2 is a unique laboratory to study stellar evolutionary processes because it’s relatively nearby, quite young, and contains a large stellar population. A 3-year ...
In our 13.8 billion-year-old universe, most galaxies, like our Milky Way, form gradually, reaching their large mass relatively late. But a new discovery made with the Atacama Large Millimeter/submillimeter Array (ALMA) of a massive rotating disk galaxy, seen when the universe was only 10 percent of its current age, challenges the traditional models of galaxy ...
