The Philae Lander on the usrface of comet P67, which went into battery-save hibernation in November, has woken up.  That's according to this BBC report of the European Space Agency (ESA). [Read more about Philae Lander has woken-up]

For all Patrick Moore fans, a new Drama based on his long broadcasting career, is now available on BBC iPlayer.

This is the story of how the self taught astronomer, whose Moon maps were later used by the Apollo missions, became the presenter of The Sky At Night. But it's also the story of a mysterious love affair, and a window into the mind of one of the nation's favourite broadcasters.

It's 1957 and the little known Patrick Moore... [Read more about Radio Drama: Far Side of the Moore]

In time honoured fashion the final lecture was delivered by Dr Alan Chapman. His subject this year was Edmond Halley, and as we soon learned Halley was not just an exceptional astronomer, his experiments, observations and research extended into many varied fields of science and professions, including fledgling scientific concepts and ideas.

Halley was born in Shoreditch on the 8th November 1656. His father, Edmond Halley Sr. came from a Derbyshire family and was a wealthy soap-maker in London. Apart from the soap business, the Halley’s had plenty of properties in London. Even though, they lost some of their assets during the 'Great Fire of London' in 1666, it hardly affected their financial status; as Alan stated; ‘they were quite well off’. 

As a child Halley was very interested in mathematics and received private tuitions at home till he was admitted to St. Pauls School where he excelled in everything he did and became the captain of the school at the age of just 15. His father had already kitted out Edmond with all the necessary astronomical equipment required and in 1673 Halley went to Queens College;Oxford and whilst an undergraduate, he published papers on the Solar System and sunspots. However, he left the college in 1675 without completing his degree and started working for John Flamsteed who was the ‘Astronomer Royal’ at the Greenwich Observatory. Among other things, Halley had the job of assigning what is now called Flamsteed numbers to stars. ‘Halley was starting to make a name for himself’...

His lecture to Astromeet was ‘The formation of planetary nebulae’.

M27: Dumbell Nebula

A very apt, timely lecture, given that it’s the 250th anniversary of the first recorded observation of a planetary nebula by Charles Messier – M27; the Dumbbell nebula, and as Albert noted, even then the view would be different to how it looks today, such is the evolution of these beautiful objects.

The term ‘Planetary nebula’ was actually coined by William Herschel, discoverer of Uranus. Through telescopes of the day planetary nebulae somewhat resembled the giant planets like Uranus, At first Herschel thought the objects were stars surrounded by material that was condensing into planets rather than what is known to be evidence of dead stars that have incinerated any orbiting planets!.

The true nature of planetary nebulae was unknown until the first spectroscopic observations were made in the mid-19th century. Planetary nebulae came to be understood as a final stage of stellar evolution. Spectroscopic observations show that all planetary nebulae are expanding. This led to the idea that planetary nebulae were caused by a star's outer layers being thrown into space at the end of its life...

It was a day full of excitement and trepidation, as the drama of the Philae Lander's despatch from the Rosetta's satellite took place, and Philae drifted in super-weak gravity towards the surface on a 7-hour journey to Comet 67P/Churyumov-Gerasimenko.

It was a day which almost didn't happen, as overnight preparations revealed a malfunction in the thruster which was to press Philae to the ground immediately on landing while harpoons tethered it to the comet surface were fired.  But the decision was taken to go ahead, and at about 08:30h GMT Philae successfully separated from Rosetta and began its descent.

The landing was confirmed at around 16:05h GMT and verified a few minutes later.  But all was not as it seemed... [Read more about 12th November 2014: The Day Mankind Landed on a Comet!]

The European Space Agency (ESA) has released three short videos about the Rosetta Mission: one focusing on the scientific objectives, another updating their mission summary, and this one - the latest in the children's animations, tells the story of the Philae lander preparing to descend to the surface of Comet 67P Churyumov-Gerasimenko.

See the full article for all three videos, and don't forget the landing itself on the 12th of November.

NASA’s Hubble Space Telescope has produced a unique composite image of comet Siding Spring as it made its never-before-seen close passage of a comet by Mars.

Here's what we know so far... [Read more about First sight: Mars meets Comet C/2013 A1 Siding Spring]

First Image of Comet Siding
Spring at closest point to Mars

Comet season is Open!  Not only is the Rosetta Satellite orbiting a comet on which it hopes to successfully deposit a lander next month, but we'll have a chance to observe Comet Siding Spring at close quarters on Sunday 19th October.

For a couple of reasons, Comet Siding Spring is providing us with a rare treat... [Read more about Comet Near Miss with Mars!]

In mid-September WDAS Members hoped to see a display of the Northern Lights after a solar flare rated X1.6.  But in April, NASA's 'Swift' Satellite witnessed a solar flare emitted from a young Red Dwarf star, estimated at X100,000.  Could our sun do that?  What would happen to an 'earth' orbiting that star? ...

A Comet's Tale

By now, everyone with any interest has seen pictures of the Rosetta Comet Chaser meeting its target: the odd-shaped comet known to its friends as '67P'.  But do you know why Rosetta is making a triangular orbit, or that it has a chameleon coma?

Physics Professor Ed Copeland of Nottingham University brings you a little more detail than you've seen on the TV news reports in this video... [Read more about A Comet's Tale]
