Scientists pinpoint the exact moment in evolutionary time when mammals became warm-blooded

Scientists have pinpointed the moment in time our earliest ancestors evolved to be warm-blooded, and it happened much later and far more quickly than the researchers expected. The discovery, made by studying the minuscule tubes of the inner ear, places the evolution of mammalian warm-bloodedness at around 233 million years ago — 19 million years …

Bad Astronomy |  The Manatee Nebula is shooting out subatomic particles

Bad Astronomy | The Manatee Nebula is shooting out subatomic particles

So, a gaseous manatee 650 light-years across is shooting out extremely high-speed subatomic particles, and while we don’t know exactly why we do know what part they’re coming from. Right, yeah, let’s back up a bit. Westerhout 50 is an immense nebula, a gas cloud in space about 18,000 light years away. It’s a supernova …

Webb telescope suffered 'uncorrectable damage' in micrometeoroid hit, NASA report says

Webb telescope suffered ‘uncorrectable damage’ in micrometeoroid hit, NASA report says

(NEXSTAR) – A micrometeoroid caused “significant uncorrectable damage” to NASA’s $10 billion James Webb Telescope, a new report explains. While experts say the impact was small, it has prompted further investigation. At 21 feet, Webb’s gold-plated, flower-shaped mirror is the biggest and most sensitive ever sent into space. It’s comprised of 18 segments, one of …

The Mystery of When Warm-Blooded Mammals Evolved May Finally Be Solved

The Mystery of When Warm-Blooded Mammals Evolved May Finally Be Solved

As the first dinosaurs were finding their feet around 230 million years ago, the ancestors of modern mammals were also emerging. Somewhere along the way they developed a remarkable ability: to generate their own warmth. This decisive evolutionary step towards endothermy – the ability to generate heat from within and keep a near-constant core body …

Scientists create strange matter in which time has 'two dimensions'

Scientists create strange matter in which time has ‘two dimensions’

Scientists have created a new phase of matter, in which time has two dimensions. The creation of an “extra” dimension in time could change the way we think about matter as well as helping build quantum computers that could themselves change the world, according to the researchers who found it. And the perplexing quality was …

The solar filament bursting over the sun

‘Canyon of fire’ solar storm to hit Earth today or tomorrow

Solar winds from the snapping of a gigantic “canyon of fire” filament on the sun are set to slam into the Earth today (July 20) or tomorrow (July 21), triggering a weak G1 geomagnetic storm. Sun watchers first spotted (opens in new tab) solar filaments as dark, thread-like lines against the sun’s bright background on …

US Gears-Up For ‘Interplanetary Defense’ Test! NASA’s DART Mission To Strike Asteroid Dimorphos In September

A NASA spacecraft is scheduled to hit an asteroid moon called Dimorphos in September this year as part of the Double Asteroid Redirection Test (DART) mission, the space agency’s first mission to test planetary defense technology. A new study simulating the potential impact of a DART spacecraft with new methods says that the spacecraft’s impact …

A solar storm hits Earth Tuesday, bringing along stunning auroras to the northern US and Canada (Pictured is Alberta)

Solar storm creates stunning auroras across the northern US

A solar storm hit Earth Tuesday, bringing along stunning auroras to the northern US and Canada. The storm made headlines over the weekend when Dr Tamitha Skov announced she spotted a ‘snake-like filament’ on the sun’s surface Friday – and it was moving toward the Earth strike zone. Auroras were seen earlier Friday morning, right …

Meet 'Qikiqtania', a fossil fish with the good sense to stay in the water while others ventured onto land

Meet ‘Qikiqtania’, a fossil fish with the good sense to stay in the water while others ventured onto land

Approximately 365 million years ago, one group of fishes left the water to live on land. These animals were early tetrapods, a lineage that would radiate to include many thousands of species including amphibians, birds, lizards and mammals. Human beings are descendants of those early tetrapods, and we share the legacy of their water-to-land transition. …
