Nasa has found 10 new planets that could host alien life

Ten potentially habitable worlds have been announced today by Nasa. They are part of a group of 219 exoplanets revealed by the space agency in its eighth Kepler planet catalogue.

The ten planets are Earth-sized and in the habitable zone of their stars. This means they are at just the right distance for liquid water to exist on their surfaces.

Just under half of these are orbiting G dwarf stars – stars the same size as our Sun.

Take a trip on Cassini as it dives through Saturn’s rings in this Nasa video

After more than a decade giving scientists an unprecedented glimpse at Saturn and its rings, Nasa’s Cassini is now on its ‘Grande Finale’ – a suicide mission into the burning heart of its planet.

Cassini completed its first in a series of dives through the 1,500-mile-wide (2,400km) gap between Saturn and its rings last week, releasing some incredible shots. Now, Nasa has combined these images to produce dizzying footage. These dives will eventually see it destroyed by the planet’s atmosphere.

Earth-like waves spotted around the Sun could help us predict space weather

High above the Earth, huge waves pass through the atmosphere, created by the path of the jet stream. Now, researchers have found the same kind of planetary wave exists in the atmosphere around the Sun.

Known as Rossby waves, the formations occur in fluids, like the atmosphere or in oceans, that are rotating with the Earth. The particular waves discovered on the Sun are likely to be related to solar activity including the formation of sunspots, active regions and the eruption of solar flares.

Comet 67P gives up more of its secrets: Nasa spots a landslide on Churyumov–Gerasimenko

Pictures taken by the Rosetta spacecraft have captured a comet landslide in action for the first time.

The trails of dust given off by a comet, known as ‘outbursts’, are well known, but what causes them has been more difficult to pin down. One theory suggests that landslides, and other changes happening on the comet’s surface, could trigger outbursts, and now, for the first time, direct evidence of such a landslide has been captured on film.
