The BBC's science site is excellent and is one of my favourites.

I love that they called the space probe Juno - why? Because in Roman Mythology, Juno could peer through Jupiter's clouds. Absolutely beautiful.

Yes it's the perfect name.

At the moment there are so many stories and links around on Juno that I have not even bothered to post them.

But here is just one that I enjoyed reading today.

The Smithsonian is doing a good job of keeping everyone up to speed on Juno.

An excellent article on the Tunguska explosion.

The Rosetta probe what has it discovered?

Another article on the new exoplanet discovery along with an actual image of the mysterious world - over 300 light years away!

^^ Love the way they put it in the seeker.com article:

"the discovery has sent orbital dynamics experts into a spin."

I imagine it would be very much harder for life to develop and survive in a system like that, than in a nice stable orbit around a single star.

Was just about to post the same thing.

I'll just add that it's on BBC Four. Or if you prefer you can watch it on iPlayer.

It used to be thought that Mars' two moons, Phobos and Deimos, were captured asteroids not least because Mars is near the asteroid belt.

However, there's a new theory based upon a collision early on in Mars' history:

For years astronomers have been trying to determine the origin of Mars’ moons, Phobos and Deimos. The long standing argument that they were captured asteroids may fall by the wayside in lieu of a new theory.

New! Pluto’s largest moon may have once had an ocean

More New!! Astronomers discover distant dwarf planet beyond Neptune. Currently designated 2015 RR245, the giant ball of ice and rock lies nine billion kilometres away in the the most distant reaches of the solar system (Note: it's not the the discovery of the Planet Nine hugeness but an icy rocklet)

Still think the gather small pieces of dust theory still stands.

One way to solve this question is to examine the composition of Phobos and Deimos in a few decades' time. If they resemble Mars' lithosphere in composition, then it's likely that they originated via the impact of a body with Mars but if they resemble other existing asteroids then the asteroid capture route is the more likely answer - we shall see.

Meanwhile, elsewhere in the solar system:

Jupiter's Great Red Spot - a hurricane three times bigger than Earth - is blasting the planet's upper atmosphere with heat, astronomers have found. Using measurements from an infrared telescope in Hawaii, a UK and US team found evidence for temperatures as high as 1,500C - hundreds of degrees warmer than anywhere else on the planet.

Not astronomy exactly - but the trailer for the re-release of arguably the greatest science-fiction film ever made.

Look at the utterly stunning visuals - and remember that this film is 48 years old.
