SpaceTime with Stuart Gary Series 19 Ep.13 - Distant lonely planet no rogue
Hi every one...here's what's in Series 19 Episode 13 - Cheers Stuart...
Distant lonely planet no rogue Astronomers have discovered that a distant planet…long thought to be floating free through space without a host star…has been found to be orbiting a star after all. However, the planet orbits its host star at a distance of a trillion kilometres -- three times greater than any other planetary system ever discovered -- and some seven thousand times further out than Earth's orbit around the Sun.
Unexpected changes in the bright spots on Ceres Scientists have discovered unexpected changes in the mysterious bright spots on the dwarf planet Ceres...the largest body in the main asteroid belt between Mars and Jupiter. Although Ceres appears as little more than a point of light from the Earth, very careful observations shows evidence that the spots constantly brighten and fade.
Rosetta finds magnetic field-free bubble at comet The European Space Agency’s Rosetta spacecraft has revealed a surprisingly large region around Comet 67P/Churyumov-Gerasimenko which is totally devoid of any magnetic field. The findings have come as a surprise to scientists who didn’t expected to be able to detect such a region.
Close comet flyby threw Mars' magnetic field into chaos A new study has found that the recent close encounter of Comet Siding Spring with Mars has had a profound impact on both the red planet’s atmosphere and magnetic field. Astronomers found Comet Siding Spring plunged the magnetic field around Mars into chaos -- blowing away part of the Martian upper atmosphere in the same way a strong solar storm would.
