Study finds that human brains react faster to non-alarming screams

A new study has revealed that a human scream can convey a complex range of emotions beyond fear and danger, and that our brains perceive and respond to them in different ways. Counter-intuitively, the study – which involved the use of brain-scanning te… Continue reading Study finds that human brains react faster to non-alarming screams

First known interstellar comet is most pristine ever discovered

The first comet known to visit our Sun after being born around an alien star may also be the most pristine comet ever discovered, according to the results of a new study. The research sheds light on the distant solar system in which the wandering body,… Continue reading First known interstellar comet is most pristine ever discovered

Enceladus’ global subsurface ocean could host salt-driven currents

Scientists have predicted the presence and movement of ocean currents in the vast subsurface ocean of the Saturnian moon Enceladus. The moon, which is sheathed in a 20 km (12.4 mile)-thick shell of ice, is one of the most promising prospects in the ong… Continue reading Enceladus’ global subsurface ocean could host salt-driven currents

Powerful protostars may not be responsible for ending their own growth

Fresh research has cast doubt on the theory that energetic outbursts from young stars blows away the cocoon of gas from which they formed, which in turn prevents them from growing any further. The Milky Way plays host to over 200 billion stars, the ear… Continue reading Powerful protostars may not be responsible for ending their own growth

Tectonic activity shown to be possible on tidally locked alien planet

Computer simulations have revealed that a hostile, tidally locked exoplanet located roughly 45 light-years from Earth is capable of hosting tectonic activity on a massive scale. Tectonic activity is considered to be one of the key processes that contri… Continue reading Tectonic activity shown to be possible on tidally locked alien planet

Astronauts undertake 7-hour spacewalk to prepare ISS for new solar arrays

NASA astronauts have completed a grueling seven-hour spacewalk in order to prepare the International Space Station (ISS) for the arrival of a new set of solar panels that will help support the ageing array that’s been serving the station since December… Continue reading Astronauts undertake 7-hour spacewalk to prepare ISS for new solar arrays

Iridium levels of submerged crater support dinosaur extinction theory

A new study has analyzed asteroid dust recently discovered in the Chicxulub asteroid crater. The findings further support the theory that the dramatic impact was the cause of the mass extinction event that wiped out the dinosaurs.Continue ReadingCatego… Continue reading Iridium levels of submerged crater support dinosaur extinction theory

NASA releases 360–degree panorama of Perseverance rover landing site

NASA has released the first HD 360-degree panorama taken by the Perseverance rover’s mast-mounted cameras since it touched down on the Red Planet on Feb. 18, 2021 . The composite image, which was captured on the third Martian day of the mission (Sol 3)… Continue reading NASA releases 360–degree panorama of Perseverance rover landing site

Galaxies stop neighbors from growing by stealing gas from their hearts

Massive galaxies may be siphoning off star-forming material from the very hearts of smaller satellite galaxies, according to the results of a newly published study. The interaction causes the smaller cosmic structures to stagnate and essentially cease … Continue reading Galaxies stop neighbors from growing by stealing gas from their hearts
