20-Year-Old Data Could Explain Ganymede’s Unique Magnetosphere

  20-Year-Old Data Could Explain Ganymede’s Unique Magnetosphere Jupiter’s moon Ganymede, the largest planetary satellite in the solar system, was studied by NASA’s Galileo spacecraft between 1996 and 2000. It is the only known moon with a magnetosphere.Larger than Mercury and Pluto, and twice as massive as the moon we are familiar with here on Earth, Ganymede is the largest natural planetary satellite in the solar system. It is thought to have a large subsurface ocean, sandwiched between two layers of ice and possibly containing more saltwater than all the water in Earth’s oceans.

An asteroid ejected from our infant Solar System found refuge billions of kilometres away, beyond the orbit of Neptune, where it has now been spotted, astronomers said Wednesday.

The curious loner is the first carbon-rich asteroid ever observed in the far-flung region called the Kuiper belt, which is filled with frozen objects, a team reported in The Astrophysical Journal Letters.

Its composition suggests the asteroid must have been formed in the inner Solar System, likely in the asteroid belt between Mars and Jupiter, before migrating to its outer reaches, said the team.

A tiny galaxy has been found hiding in orbit around the Milky Way

  A tiny galaxy has been found hiding in orbit around the Milky Way The dwarf galaxy has been dubbed ‘snake in the clouds’ and sits 90,000 lightyears away from the sun , the researchers explain Hydrus 1 is a faint, mildly elliptical galaxy that stretches only about 326 lightyears across. By comparison, our own Milky Way galaxy is around 100,000 lightyears across. “Hydrus 1’s velocity dispersion indicates the system is dark matter dominated, but its dynamical mass-to-light ratio is significantly smaller than typical for ultra-faint dwarfs at similar luminosity,” the researchers wrote in the paper.

The curious loner is the first carbon-rich asteroid ever observed in the far-flung region called the Kuiper belt, which is.

This makes it "a relic of the primordial Solar System", they added.

Theoretical models of our early Solar System describe a tempestuous time with gas giant planets on the rampage, ejecting small rocky bodies from its the system's centre to far-flung orbits.

Such models suggest the Kuiper Belt should contain a small number of rocky bodies, perhaps also carbon-rich asteroids.

The new observation, using telescopes of the European Southern Observatory in Chile, provides "strong support for these theoretical models of our Solar System's troubled youth," said an ESO statement.

Jeff Bezos is spending $1 billion worth of Amazon stock each year to get to space

  Jeff Bezos is spending $1 billion worth of Amazon stock each year to get to space Amazon founder Jeff Bezos has confessed that his ecommerce, cloud and publishing enterprises come second to — and fund — his “most important work”: space tourism and reusable rockets. Speaking in an interview with Mathias Döpfner, chief executive of Axel Springer, Bezos confessed he is liquidating around $US 1 billion ($AUD $1.3 billion) of Amazon stock every year to fund his space travel project, Blue Origin.Business Insider reports Bezos called large-scale space travel the only way to avoid a “civilisation of stasis”, or a situation in which humans’ energy output, productivity and population is limited.

The asteroid was spotted partly because it reflects light differently than other objects in the Kuiper Belt, which are icy while asteroids are rocky.

"It looked enough of a weirdo for us to take a closer look," said study lead author Tom Seccull of Queen's University Belfast.

It is, nevertheless, very difficult to study.

The 300 kilometre-wide (186 mile) space rock is four billion kilometres from Earth, and dark.

"It's like observing a giant mountain of coal against the pitch-black canvas of the night sky," said co-author Thomas Puzia of the Pontifical Catholic University of Chile.

Dubbed 2004 EW95, the asteroid is moving, and feint.

"We had to use a pretty advanced data processing technique to get as much out of the data as possible," said Seccull.

The asteroid was mysteriously "lost" to astronomers for a number of years.Estimated to stretch about 170-400 feet across, asteroid 2010 WC9 should pass at about half the distance to the Moon at its closest approach at 6:05 p.m. ET. It’s not a particularly big asteroid, but this will be a pretty close encounter for a space rock of this size.
