Water could exist on all of them.
Roundup from ESA WebTV of Paris Air and Space Show
Roundup of Day 4 at the Paris Air and Space Show, 22 June
The announcement of the draft Spaceflight Bill in the Queen's Speech will allow the development of spaceports in the UK. This could see members of the paying public launched into space as tourists, or taking sub-orbital flights from London to New York in just 45 minutes.
During its journey, Cassini has made many discoveries, including a global ocean with hydrothermal activity within Saturn's moon Enceladus, and vast seas of liquid methane on the planet's largest moon, Titan. Cassini began the final, dramatic phase of its mission,...
Astrophysicists from the International School for Advanced Studies (SISSA) in Trieste, Italy, speculated in a 2015 study that wormholes, predicted by Einstein in his theory of General Relativity as areas where space and time are bent to manipulate the distance,...
At any given moment, as many as 10 million wild jets of solar material burst from the sun's surface. They erupt as fast as 60 miles per second, and can reach lengths of 6,000 miles before collapsing. These are spicules,...
Starshade is a proposed flower-shaped spacecraft that can create an artificial eclipse, allowing space telescopes to spot planets orbiting distant stars.
(NASA/Goddard Space Flight Center) For the first time, a computer simulation -- so detailed it took a full year to run -- shows how spicules form, helping scientists understand how spicules can break free of the sun's surface and surge upward so quickly.
(RIKEN) Using elaborate computer simulations, a team of researchers from RIKEN in Japan and the Max Planck Institute for Astrophysics (MPA) were able to explain the recently measured spatial distributions of radioactive titanium and nickel in Cassiopeia A, a roughly 340 year old gas remnant of a nearby supernova.

NASA's senior Mars rover, Opportunity, is examining rocks at the edge of Endeavour Crater for signs that they may have been either transported by a flood or eroded in place by wind.
Deep in space between distant stars, space is not empty. Instead, there drifts vast clouds of neutral atoms and molecules, as well as charged plasma particles called the interstellar medium—that may, over millions of years, evolve into new stars and even planets. Show More Summary
This August, the U.S. will experience its first coast-to-coast total solar eclipse in 99 years.
'Being in space is like having superpowers', Thomas Pesquet at the Paris Air and Space Show (French)
Researchers at the Tata Institute of Fundamental Research in Mumbai have proposed a theory that predicts how dark matter may be annihilating much more rapidly in the Milky Way, than in smaller or larger galaxies and the early Univer...
Long-term power cuts, destruction of electronic devices and increased cancer risk for aeroplane passengers are all potential effects of the Earth being hit by a powerful solar eruption.
A team of laboratory astrophysicists from Leiden University (the Netherlands) managed to make glycerol under conditions comparable to those in dark interstellar clouds. They allowed carbon monoxide ice to react with hydrogen atoms at minus 250 degrees Celsius. The researchers published their findings in the Astrophysical Journal.
ESA (the European Space Agency) has selected the Laser Interferometer Space Antenna (LISA) for its third large-class mission in the agency's Cosmic Vision science program. The three-spacecraft constellation is designed to study gravitational waves in space and is a concept long studied by both ESA and NASA.
As the Mars Pathfinder spacecraft approached its destination on July 4, 1997, no NASA mission had successfully reached the Red Planet in more than 20 years.
Just before sunrise, there's typically nothing atop Round Butte but the whistle of the wind and a panoramic view of Oregon's second-highest peak glowing pink in the faint light.
