Pluto’s Atmosphere and plasma tail. NEW FINDINGS AMAZE

Well here is some data and analysis from New Horizons fly by.

Many  surprises have already been revealed in the data thus far released from NASA’s New Horizons mission. Today, physicist Eugene Bagashov discusses what we have learned thus far about Pluto’s atmosphere and the larger Plutonian environment.

New Horizons has discovered a region of cold, dense ionized gas tens of thousands of miles beyond Pluto — the planet’s atmosphere being stripped away by the solar wind and lost to space. Beginning an hour and half after closest approach, the Solar Wind Around Pluto (SWAP) instrument observed a cavity in the solar wind — the outflow of electrically charged particles from the Sun — between 48,000 miles (77,000 km) and 68,000 miles (109,000 km) downstream of Pluto. SWAP data revealed this cavity to be populated with nitrogen ions forming a “plasma tail” of undetermined structure and length extending behind the planet.

Also other interesting data on other planets atmospheres including our own earth.

Well worth a watch.

Tiny magnets mimic steam, water and ice

Researchers at the Paul Scherrer Institute (PSI) announced they have created a synthetic material with magnetic properties capable of changing states – just as water changes from solid ice to liquid or steam – with temperature change.

Honeycomb of nanomagnets

The magnets are only 63 nanometres long and shaped roughly like grains of rice. The researchers used a highly advanced technique to place 1 billion of these tiny grains on a flat substrate to form a large-scale honeycomb pattern. The nanomagnets covered a total area of five by five millimetres.

Thanks to a special measuring technique, the scientists initially studied the collective magnetic behaviour of their metamaterial at room temperature. Here there was no order in the magnetic orientation: the magnetic north and south poles pointed randomly in one direction or another.

When the researchers cooled the metamaterial gradually and constantly, however, they reached a point where a higher order appeared: the tiny magnets now noticed each other more than before. As the temperature fell further, there was another change towards an even higher order, in which the magnetic arrangement appeared almost frozen. The long-range order of water molecules increases in a similar way at the moment when water freezes into ice. “We were fascinated by the fact that our synthetic material displayed this everyday phenomenon of a phase transition,” says Heyderman

Maybe the laws of physics are wrong ? Nasa’s successful testing of an Electromagnetic drive system

A group at NASA’s Johnson Space Center has successfully tested an electromagnetic (EM) propulsion drive in a vacuum – a major breakthrough for a multi-year international effort comprising several competing research teams.

Thrust measurements of the EM Drive defy classical physics’ expectations that such a closed (microwave) cavity should be unusable for space propulsion because of the law of conservation of momentum.

Nasa space drive

According to classical physics, the EMDrive should be impossible because it seems to violate the law of conservation of momentum.

The law states that the momentum of a system is constant if there are no external forces acting on the system – which is why propellant is required in traditional rockets.


A controversial design for a new, advanced type of space travel received a boost as German scientists confirmed that it does in fact work.

The EMDrive propulsion system would permit travel at speeds until now only seen in science fiction.

When the concept was first proposed it was considered impossible because it went against the laws of physics.

But subsequent tests – further backed up by this announcement – have shown that the idea could revolutionise space travel.

The system is based on electromagnetic drive, or EMDrive, which converts electrical energy into thrust without the need for rocket fuel.
