Today, 31st July 2013 marks the start of a New Year on Mars. The counting of the Martian year started on April 11th 1955, and because it takes the planet nearly twice as long as the Earth to orbit the sun (668 days), officially it is only the Year 32!
The two recently discovered moons of Pluto now have official names: Kerberos and Styx. They measure only 10-25km across and bring the total of Pluto's moons to five.
The names were chosen by a public vote and refer to a three-headed dog (Kerberos) and a river separating the living from the dead (Styx).
Unfortunately for Star Trek fans the name Vulcan (which actually won the vote) was vetoed by the International Astronomical Union as tradition states that names should only come from Greek or Roman mythology.
Pluto's Moons: Charon - Nix - Hydra - Kerberos - Styx
The dictionary definition of a black hole is: A region of space having a gravitational field so intense that no matter or radiation can escape.
And on that note, astronomers have discovered 26 new likely black holes in the neighboring Andromeda galaxy which brings the total to 35!

Did you know that Jupiter has around 66 moons! They dramatically differ in size from bigger than the planet Mercury to only 1 kilometre in radius. The planet's four largest moons are Io, Europa, Ganymede and Callisto and were discovered by Italian astronomer Galileo Galilei in 1610.

The nearest star to our own is Proxima Centauri at 4.33 light years away. If you travelled as fast as the Voyager probe (38,000 miles per hour), it would still take you 76,000 years to get there!
New research has suggested that the Earth's inner core is far hotter than previously thought. It measured 6,000C making it is as hot as the surface of the sun.
On this day Nicolaus Copernicus made his first observations of Saturn. He was a Polish astronomer, born in 1473 and is best known for his theory that the Sun and not the Earth is at the centre of the universe.
There is a full moon tonight but this one special as it is passing through the earth's shadow. Although not a full eclipse, at around 20:30 BST it will start getting darker on its northern edge.
On this day in 1990 the space shuttle Discovery blasted off from Cape Canaveral carrying the Hubble Space Telescope.
The telescope, the size of a railway carriage, took 20 years to build, at a cost of $1.55 billion. Its been well worth it as it still making discoveries 23 years later and has transformed the way scientists look at the universe.
It has its own website, click on the link to see some stunning images of the cosmos.
Astronomers have found two planets orbiting a distant star that are close to Earth-sized. They are also in the "habitable zone", a distance from the sun that makes the planets' surfaces neither too hot nor too cold, but just right for life?
