Rosetta mission scientist Matt Taylor says the science team is jubilant after the Philae lander captured the historic, first close up images of the surface of a comet and began returning data from its science instruments.
Somewhat appropriately spooky for Halloween in recent radar images, 600 metre-wide near-Earth object 2015 TB145 dashes by our planet today. Now believed to be a dead comet that has shed its volatiles after numerous passes around the Sun, the object makes its closest approach to Earth at 5pm GMT. UK observers with clear skies may see it with modest telescopes in the early evening.
Scientists from Rosetta’s OSIRIS team have discovered an extraordinary formation in the Aker region on the larger lobe of comet 67P/Churyumov-Gerasimenko. The largest of a group of three boulders with a diameter of approximately 30 metres appears to perch on the rim of a small depression. There seems to be only a very small contact area with the nucleus.
