Astronomers have discovered a chemically rich collection of sulfur-bearing molecules surrounding the rare massive star HD 87643. The observations include the first detection of sulfur monoxide and sulfur dioxide around a ...
For decades, astronomers have assumed that the Martian surface froze solid around 3 billion years ago and has stayed that way ever since. If this were really the case, any liquid water would have long since either been locked ...
Venus may be overwhelmingly inhospitable today, but many planetary scientists believe that it wasn't always this way. Billions of years ago, some observational evidence suggested that our planetary neighbor may have looked ...
Nearly a decade after the discovery of LHS 1140b, a rocky exoplanet in the habitable zone of a nearby low-mass star, a new study reveals that the object may have its own atmosphere.

Scientists have detected evidence of landslides on Pluto for the first time. A paper published in the journal Icarus reports that images taken by the New Horizons spacecraft during a flyby revealed six large landslides in ...
Sugars are key biomolecules in living organisms, as they form the backbone of DNA and RNA and play a fundamental role in metabolic processes. In theories of the origin of life, sugars are also essential for the synthesis ...

When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of biology because they are often produced by living microbes. However, scientists can be misled because ...
Like a shelf in an old house, the Earth collects a lot of dust from its surroundings. This "space dust" is mostly made up of micrometeorites that survive atmospheric entry and provides researchers with a cheap and easy way ...
