Published Interstellar signal linked to aliens was actually just a truck



Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that meteor, as was widely reported.
Published Earth's earliest forest revealed in Somerset fossils



The oldest fossilized forest known on Earth -- dating from 390 million years ago -- has been found in the high sandstone cliffs along the Devon and Somerset coast of South West England.
Published Baby quasars: Growing supermassive black holes



The James Webb Space Telescope makes one of the most unexpected findings within its first year of service: A high number of faint little red dots in the distant Universe could change the way we understand the genesis of supermassive black holes.
Published Finding new physics in debris from colliding neutron stars



Neutron star mergers are a treasure trove for new physics signals, with implications for determining the true nature of dark matter, according to physicists.
Published Astronomers spot oldest 'dead' galaxy yet observed



A galaxy that suddenly stopped forming new stars more than 13 billion years ago has been observed by astronomers. Using the James Webb Space Telescope, astronomers have spotted a 'dead' galaxy when the universe was just 700 million years old, the oldest such galaxy ever observed.
Published Discovery tests theory on cooling of white dwarf stars



Open any astronomy textbook to the section on white dwarf stars and you'll likely learn that they are 'dead stars' that continuously cool down over time. Astronomers are challenging this theory after discovering a population of white dwarf stars that stopped cooling for more than eight billion years.
Published Space tourism? Cosmic radiation exposure



Space weather experts are urging regulators and space tourism innovators to work together to protect their passengers and crews from the risks of space weather radiation exposure.
Published Fossils of giant sea lizard with dagger-like teeth show how our oceans have fundamentally changed since the dinosaur era



Fossils of a strange new species of marine lizard with dagger-like teeth that lived 66 million years ago, show a dramatically more biodiverse ocean ecosystem to what we see today.
Published Groundbreaking survey reveals secrets of planet birth around dozens of stars



A team of astronomers has shed new light on the fascinating and complex process of planet formation. The research brings together observations of more than 80 young stars that might have planets forming around them, providing astronomers with a wealth of data and unique insights into how planets arise in different regions of our galaxy.
Published What makes black holes grow and new stars form? Machine learning helps solve the mystery



It takes more than a galaxy merger to make a black hole grow and new stars form: machine learning shows cold gas is needed too to initiate rapid growth -- new research finds.
Published Juno spacecraft measures oxygen production on Jupiter's moon, Europa



NASA's Juno spacecraft has directly measured charged oxygen and hydrogen molecules from the atmosphere of one of Jupiter's largest moons, Europa. These observations provide key constraints on the potential oxygenation of its subsurface ocean.
Published Fossil named 'Attenborough's strange bird' was the first in its kind without teeth



A new fossil, named 'Attenborough's strange bird' after naturalist and documentarian Sir David Attenborough, is the first of its kind to evolve a toothless beak. It's from a branch of the bird family tree that went extinct in the mass extinction 66 million years ago, and this strange bird is another puzzle piece that helps explain why some birds -- and their fellow dinosaurs -- went extinct, and others survived to today.
Published JWST captures the end of planet formation



The James Webb Space Telescope is helping scientists uncover how planets form by advancing understanding of their birthplaces and the circumstellar disks surrounding young stars. Scientists have imaged winds from an old planet-forming disk (still very young relative to the Sun) which is actively dispersing its gas content. Knowing when the gas disperses is important as it constrains the time left for nascent planets to consume the gas from their surroundings.
Published Modeling the origins of life: New evidence for an 'RNA World'



Scientists provide fresh insights on the origins of life, presenting compelling evidence supporting the 'RNA World' hypothesis. The study unveils an RNA enzyme that can make accurate copies of other functional RNA strands, while also allowing new variants of the molecule to emerge over time. These remarkable capabilities suggest the earliest forms of evolution may have occurred on a molecular scale in RNA, and also bring scientists one step closer to re-creating autonomous RNA-based life in the laboratory.
Published Webb unlocks secrets of one of the most distant galaxies ever seen



Looking deeply into space and time, astronomers have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old universe was only about 430 million years old.
Published Study determines the original orientations of rocks drilled on Mars



Geologists determined the original orientation of many of the Mars bedrock samples collected by the Perseverance rover. The findings can give scientists clues to the conditions in which the rocks originally formed.
Published New insights on how galaxies are formed



Astronomers can use supercomputers to simulate the formation of galaxies from the Big Bang 13.8 billion years ago to the present day. But there are a number of sources of error. An international research team has spent a hundred million computer hours over eight years trying to correct these.
Published Ultraviolet radiation from massive stars shapes planetary systems



Up to a certain point, very luminous stars can have a positive effect on the formation of planets, but from that point on the radiation they emit can cause the material in protoplanetary discs to disperse.
Published Ice shell thickness reveals water temperature on ocean worlds



Astrobiologists have devised a novel way to determine ocean temperatures of distant worlds based on the thickness of their ice shells, effectively conducting oceanography from space.
Published Scientists ID burned bodies using technique used for extracting DNA from woolly mammoths, Neanderthals



A technique originally devised to extract DNA from woolly mammoths and other ancient archaeological specimens can be used to potentially identify badly burned human remains, according to research.
