An anomalous group effect in which all photons merge into two output beams. Credit: Ursula Cardenas Mamani Three researchers from the Université libre de Bruxelles, Belgium, have uncovered a counterintuitive aspect of the physics of photon interference. In an article published this month in Photonics of nature, they proposed a thought experiment that completely contradicts...

Isle of Wight Fossils Identified as New Dinosaur Species | dinosaurs
Fossilized remains from the Isle of Wight have been identified as a new species of dinosaur, which has been named after a palaeontologist from the Natural History Museum in London. It belongs to a group of plant-eating dinosaurs known as ankylosaurs that were discovered in the 1980s in the island’s Wessex Formation, a geological feature...

The mystery of how water arrived on Earth may finally be solved
Did an ancient asteroid bring water to Earth? (Getty Images) Tiny crystals of table salt found in an asteroid sample may help explain the enduring mystery of how water arrived on Earth. The crystals discovered by researchers at the University of Arizona’s Lunar and Planetary Laboratory (LPL) can only form in the presence of liquid...

Tatooine is a real planet after an amazing discovery
Scientists have discovered a planet that, like the iconic Star Wars planet Tatooine, orbits two suns. Fans of Star Wars and real-life space travel will enjoy the latest news from Space.com, which reports that a new planet, titled BEBOP-1c, which resembles conditions on Luke Skywalker’s home planet Tatooine, has been discovered orbiting a pair of...

Software finds more satellite photobombs in Hubble images • The Register
Researchers have developed software they believe will be at least 10 times more effective than existing algorithms at detecting the pesky satellite trails that increasingly appear in Hubble Space Telescope images. The team from Baltimore’s Space Telescope Science Institute (STScI) also claims that their software identified roughly twice as many trails as other studies. “We...

NASA to the rescue after potential ‘internet apocalypse’
This representative photo shows the US National Aeronautics and Space Administration (NASA).— AFP/File NASA has come to the world’s aid to avoid a potential threat to Internet access, better known as an Internet apocalypse, a situation that could shut down people’s Internet access for months or years, rendering satellites and power cables unusable. The space...

Supernova explosion revealed by rare ‘space magnifiers’
Scientists have discovered a rare gravitationally lensed supernova, ‘SN Zwicky’, which provides unique insight into the cores of galaxies, dark matter and the mechanics of the universe’s expansion. This discovery uses gravitational lensing, a phenomenon that magnifies celestial objects, according to Einstein’s theory of relativity. Researchers are gaining insight into how the universe is expanding...

Beams of the brightest gamma ray ever seen were aimed directly at Earth • The Register
The brightest gamma-ray burst ever detected, codenamed GRB 221009A, has a strange structure that astronomers have never seen before. On October 9, 2022, high-energy space surveillance satellites detected an extremely bright gamma-ray signal that suddenly erupted from the constellation Sagittarius; lasted hundreds of seconds. The burst was later determined to be the most energetic flare...

Why do some species survive mass extinctions? Hidden “whole genome duplication” may be the secret
Geneticists have discovered a past whole-genome duplication (WGD) event in the common ancestor of sturgeons and scallops that occurred just before a significant mass extinction, potentially providing these species with advantageous genetic variation. This finding also raises the possibility of similar neglected WGDs in the lineages of other species that may have contributed to survival...
