The 'habitable edge' of exomoons

Astronomers have their fingers crossed that within the haul of data collected by NASA's Kepler mission, which has already detected nearly three thousand possible exoplanets, hide the signatures of the very first exomoons.

A study of Saturn's largest moon may offer insights for Earth

Scientists studying the weather and climate of Titan, Saturn's largest moon, have reported a significant seasonal variation in its energy budget—that is the amount of solar energy absorbed by the celestial body and the ...

Evaluating the energy balance of Saturn's moon Titan

To understand the weather and climate on Earth as well as on other planets and their moons, scientists need to know the global energy balance, the balance between energy coming in from solar radiation and thermal energy radiated ...

Annual Arctic sea ice less reflective than old ice

In the Arctic Ocean, the blanket of permanent sea ice is being progressively replaced by a transient winter cover. In recent years the extent of the northern ocean's ice cover has declined. The summer melt season is starting ...

Coal still top threat to global climate goals: report

The number of coal-fired power plants in the pipeline worldwide declined in 2021, according to research released Tuesday, but the fossil fuel most responsible for global warming still generated record CO2 emissions, threatening ...

Detecting dark matter with quantum computers

Dark matter makes up about 27% of the matter and energy budget in the universe, but scientists do not know much about it. They do know that it is cold, meaning that the particles that make up dark matter are slow-moving. ...

Veritable powerhouses—even without DNA

Whether human beings or animals, plants or algae: the cells of most life forms contain special structures that are responsible for energy production. Referred to as mitochondria, they normally have their own genetic material, ...

Billion dollar boost for US science, health research?

Health and science research would get a billion-dollar boost under the 2012 budget proposed Monday by US President Barack Obama, including a major new project to speed lab advances into cures.

Climate of Jupiter and Saturn may yield clues to Earth's weather

What can the climates of other planets tell us about the Earth's weather? According to a researcher at the University of Houston, data being collected from Jupiter, Saturn and Saturn's largest moon, Titan, can offer clues ...
