View ArticleDoes the exoplanet Trappist-1 b have an atmosphere after all?
Recent measurements with the James Webb Space Telescope (JWST) cast doubt on the current understanding of the exoplanet Trappist-1 b's nature. Until now, it was assumed to be a dark rocky planet...
View ArticleNew paper examines the elusive nature of liquid brines on Mars
The combination of low temperature, atmospheric pressure and water vapor pressure on Mars means any liquid water found there would likely freeze, boil or evaporate immediately, making its presence...

Microgravity is known to alter the muscles, bones, the immune system and cogni tion, but little is known about its specific impact on the brain. To discover how brain cells respond to microgravity,...
View ArticleA 'remelting' of lunar surface adds a wrinkle to mystery of Moon's true age
Scientists propose a 'remelting' of the Moon's surface 4.35 billion years ago due to the tidal pull of Earth causing widespread geological upheaval and intense heating.
View ArticleMassive black hole in the early universe spotted taking a 'nap' after overeating
Scientists have spotted a massive black hole in the early universe that is 'napping' after stuffing itself with too much food. Like a bear gorging itself on salmon before hibernating for the winter, or...
View ArticleSurvey of 26,000 dead stars confirms key details of extreme stellar behavior
A study of more than 26,000 white dwarf stars has confirmed a long-predicted but elusive effect in these ultra-dense, dying stars: Hotter white dwarfs are slightly puffier than cooler ones, even when...
View ArticleUncovering a 'centaur's' tracks: Scientists examine unique asteroid-comet hybrid
Scientists recently led a team that found, for the first time, that Chiron has surface chemistry unlike other centaurs. Its surface it has both carbon dioxide and carbon monoxide ice along with carbon...
View ArticleSupermassive black holes halt rapid construction in an ancient celestial city
Galaxy clusters -- the big cities of the universe -- are home to many giant elliptical galaxies that have completed their growth and are not forming stars. However, it is still unclear what has shut...
View ArticleNew evidence exists for hidden water reservoirs and rare magmas on ancient Mars
A new study explores how variations in Mars' crustal thickness during its ancient history may have influenced the planet's magmatic evolution and hydrological systems. The research suggests that the...
