Astronomers have discovered bloated Jupiter-sized worlds that are so precariously close to their parent star they are being roasted at seething temperatures above 3,000 degrees Fahrenheit. That's hot enough to vaporize most metals, including titanium. They have the hottest planetary atmospheres ever seen. Hubble astronomers are reporting on bizarre weather conditions on these sizzling worlds. It's raining vaporized rock on one planet, and another one has its upper atmosphere getting hotter rather than cooler because it is being 'sunburned' by intense ultraviolet (UV) radiation from its star.

Researchers are investigating the psychological impact of social isolation in harsh environments, such as on the Moon.

Extinct for 66 million years, T. rex still inspires speculation about its anatomy, behavior and fierce physique. One conundrum: its peculiarly short forelimbs, which have relatively limited mobility. While scientists have suggested explanations, a paleontologist puts the proposals to the test and finds them wanting. He hypothesizes that the arms reduced in size to limit damage, possibly fatal, when a pack of T. rexes descended on a carcass with their bone-crunching teeth.

Prehistoric mammals bulked up, rather than develop bigger brains, to boost their survival chances once dinosaurs had become extinct, research suggests.

NASA's Hubble Space Telescope has established an extraordinary new benchmark: detecting the light of a star that existed within the first billion years after the universe's birth in the big bang -- the farthest individual star ever seen to date.

Scientists have discovered a new source of super-fast, energetic electrons raining down on Earth's atmosphere, a phenomenon that contributes to the colorful aurora borealis and poses hazards to satellites, spacecraft and astronauts.

Spinosaurus is the largest predatory dinosaur known -- over two metres longer than the longest Tyrannosaurus rex -- but the way it hunted has been a subject of debate for decades. In a new paper, palaeontologists have taken a different approach to decipher the lifestyle of long-extinct creatures: examining the density of their bones.

New research has revealed that soil erosion and wildfires contributed to a mass extinction event 201 million years ago that ended the Triassic era and paved the way for the rise of dinosaurs in the Jurassic period.

Researchers have recently discovered a breakthrough in magnetic reconnection that could ultimately help predict space weather.

Scientists describe the find of a new softshell turtle from the end of the Cretaceous Period.

Relatively small, but fearsome-looking stegosaur measured about 2.8 meters (9 feet) from nose to tail -- but scientists can't tell whether the remains are those of an adult or juvenile.

A physics professor has developed an innovative activity that poses the question: Is Usain Bolt faster than a 900-pound dinosaur?

Scientists have mapped 300 years of research on the prehistoric marine reptiles known as ichthyosaurs. Using a uniquely well-preserved fossil, the team has also created the scientifically most up-to-date reconstruction of an ichthyosaur currently available.

A new analysis of Tyrannosaurus skeletal remains reveals physical differences in the femur, other bones and dental structures across specimens that could suggest Tyrannosaurus rex specimens need to be re-categorized into three distinct groups or species, reports a new study.

The asteroid which killed nearly all of the dinosaurs struck Earth during springtime. This conclusion was drawn by an international team of researchers after having examined thin sections, high-resolution synchrotron X-ray scans, and carbon isotope records of the bones of fishes that died less than 60 minutes after the asteroid impacted.

A spectacular head-on collision between two galaxies fueled the unusual triangular-shaped star-birthing frenzy, as captured in a new image from NASA's Hubble Space Telescope.

Two new species of fossil birds that lived alongside the dinosaurs have ben discovered near the Great Wall of China. One of the new species had a sensitive, movable bony appendage at the tip of its lower jaw that it might have used to find food.

Scientists have discovered the first evidence of a unique respiratory infection in the fossilized remains of a dinosaur that lived nearly 150 million years ago. Researchers examined the remains of an immature diplodocid -- a long-necked herbivorous sauropod dinosaur, like 'Brontosaurus' - dating back to the Late Jurassic Period of the Mesozoic Era. The dinosaur nicknamed 'Dolly,' discovered in southwest Montana, had evidence of an infection in the area of its neck vertebrae.

New research has shown that future gravitational wave detections from space will be capable of finding new fundamental fields and potentially shed new light on unexplained aspects of the Universe.

Space scientists have discovered a never-before-seen mechanism fueling huge planetary aurorae at Saturn.
