Le Bourget Roundup

Roundup from ESA WebTV of Paris Air and Space Show

Le Bourget Day 4

Roundup of Day 4 at the Paris Air and Space Show, 22 June

Space tourism could boost science and health research—here's how

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.

NASA's Cassini Mission Grand Finale at Saturn --Join Live At NASA's Jet Propulsion Lab (Today's 'Galaxy' Stream)

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,...        

The Milky Way --"Could Harbor a Spacetime Tunnel the Size of the Galaxy Itself Hiding in Dark Matter" (Today's Most Popular)

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,...        

Mystery of Sun's Erupting Plasma Jets Solved --"Reach Heights of 6,000 Miles"

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,...        

This giant, flower-shaped starshade creates an artificial eclipse to see distant exoplanets

Starshade is a proposed flower-shaped spacecraft that can create an artificial eclipse, allowing space telescopes to spot planets orbiting distant stars.

Scientists uncover origins of the sun's swirling spicules

(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.

Radioactive elements in Cassiopeia A suggest a neutrino-driven explosion

(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.

Mars rover Opportunity on walkabout near rim

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.

CHESS mission will check out the space between stars

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

Total solar eclipse 1st in 99 years to sweep width of US

This August, the U.S. will experience its first coast-to-coast total solar eclipse in 99 years.

Superpowers in Space

'Being in space is like having superpowers', Thomas Pesquet at the Paris Air and Space Show (French)

Does dark matter annihilate quicker in the Milky Way?

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...

Sun eruptions hit Earth like a 'sneeze', say scientists

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.

Dutch astronomers discover recipe to make cosmic glycerol

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 to develop gravitational wave space mission with NASA support

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. 

Why no one under 20 has experienced a day without NASA at Mars

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.

Total solar eclipse casts spotlight on rural Oregon town

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.
