Earlier this year, in an experiment about five-feet long, researchers say they observed evidence of the abrupt transition of hydrogen from liquid insulator to liquid metal. It is one of the first times such a transition has ever been observed in any experiment.

There are advances being made almost daily in the disciplines required to make space and its contents accessible. This blog brings together a lot of that info, as it is reported, tracking the small steps into space that will make it just another place we carry out normal human economic, leisure and living activities.

In the blink of a cosmic eye: Chance microlensing events probe galactic cores
more »
Some galaxies pump out vast amounts of energy from a very small volume of space, typically not much bigger than our own solar system. The cores of these galaxies, so called Active Galactic Nuclei or AGNs, are often hundreds of millions or even billions of light years away, so are difficult to study in any detail. Natural gravitational 'microlenses' can provide a way to probe these objects, and now a team of astronomers have seen hints of the extreme AGN brightness changes that hint at their presence.

Autolens analysis steps up for Euclid’s 100,000 strong gravitational lens challenge
more »
Euclid satellite, due for launch in 2020, will set astronomers a huge challenge: to analyze one hundred thousand strong gravitational lenses. The gravitational deflection of light from distant astronomical sources by massive galaxies (strong lenses) along the light path can create multiple images of the source that are not just visually stunning, but are also valuable tools for probing our Universe.

Juno Approaching Jupiter
more »
Approaching over the north pole after nearly a five-year journey, Juno enjoys a perspective on Jupiter not often seen, even by spacecraft from Earth that usually swing by closer to Jupiter's equator. Looking down toward the ruling gas giant from a distance of 10.9 million kilometers, the spacecraft's JunoCam captured this image with Jupiter's nightside and orbiting entourage of four large Galilean moons on June 21. JunoCam is intended to provide close-up views of the gas giant's cloudy zoned and belted atmosphere and on July 4 (July 5 UT) Juno is set to burn its main engine to slow down and be captured into its own orbit. If all goes well, it will be the first spacecraft to orbit the poles of Jupiter, skimming to within 5,000 kilometers of the Jovian cloud tops during the 20 month mission. Tomorrow's picture: light-weekend
