Rosetta fuels debate on Earth's oceans12/16/14
New data shows Earth's oceans came from asteroids not comets. Also; Curiosity confirms Mars was once warm with regular wet seasons, and dark matter could be linked to a hypothetical subatomic particle called the sterile neutrino.
Galactic evolution is in the stars
How hot young stars can change the evolution of entire galaxies. Also; the Martian meteorite that's reignited debate about the possibility of life on the red planet, and new mysteries surrounding the Moon's long gone magnetic field.
DNA survives in space
DNA survives the extremes of unprotected exposure in space to remain viable upon return to Earth. Also, discovery of a mysterious shield protecting our planet from high energy electrons, and the rock from deep space which has finally put a name to the...
How black holes feed quasars
There's growing evidence that the strange physics in black holes provides the energy to power quasars. Also; how the Sun causes lightning on Earth, And NASA's new Orion spacecraft arrives at the Kennedy Space Centre for its first test flight.
Philae's mission completed before shutdown
Philae completes experiments on Comet 67P despite ending up off target. Also; did volcanoes give early Mars its rivers and lakes? And Jupiter's great red spot most likely caused by sunburn rather than a blush.
Touchdown! Philae lands on comet
History made as the first spacecraft successfully lands on a comet. Also; astronomers peer deep into the heart of a supernova, and up to half the stars in the universe may be orphans.
Virgin Galactic spaceship crashes
Investigation continues into tragic Virgin Galactic crash. Also; first stage engine malfunction a possible cause of Antares rocket failure, and China completes its first return mission to the Moon.
Nova blast shines in brilliant detail
Astronomers get an unprecedented view of the fireball from an exploding star. Also China takes another step in its plans to send taikonauts to the Moon, and Antares rocket explodes seconds after launch.
Have we finally found dark matter?
New X-ray data suggests the possible detection of proposed dark matter particles called axions. Also; plasma bombs and tornadoes detected on the Sun, and secret space shuttle lands after 22 months in orbit.
Meet Earth's fifth 'moon'
Scientists discover another 'moon' orbiting Earth. Also; a new subatomic particle improves our understanding of the fundamental forces of nature, and the Milky Way only has half as much dark matter as previously thought.
The first stars almost within reach
Astronomers move a step closer to seeing the first stars to shine in the universe. Also; new satellite data reveals Earth's ocean abyss in unprecedented detail, and the last lunar eclipse for 2014.
Water older than the solar system
Up to half the water on Earth may be older than the Sun. Also; gravitational wave discovery claims turn to dust, and meteor strikes may not be random.
Mars' orbit gets more crowded
Two new missions arrive at the Red Planet. Also; size doesn't matter if you're a black hole! And strength of electromagnetism hasn't changed in 10 billion years.
Rosetta's comet landing site selected
Rosetta mission managers choose a site for the historic first landing on the comet. Also; NASA's Curiosity rover arrives at its final destination at the Martian peak Mount Sharp, and a new Australian telecommunications satellite launches into orbit.
Finding our place in the universe
Astronomers discover we belong to a galactic supercluster which they've named Laniakea. Also; a new study suggests Jupiter's ice moon Europa has plate tectonics, and NASA's IRIS mission to study the Sun.
Scientists peer into the Sun's core
Astronomers detect neutrino particles generated in the core of the Sun. Also; bubble around solar system formed as cluster of nearby supernovae exploded about ten million years ago, and birth of a massive galaxy seen for the first time.
Two white dwarfs may fuel supernovae
Astronomers discover fusion of two white dwarfs may cause thermonuclear supernovae. Also; five potential target sites selected for Rosetta's historic mission to land on a comet, and New Horizons passes the orbit of Neptune on its way to our first...
Volcanism on asteroids in early solar system
Analysis of rare meteorite shows volcanic activity present on asteroids in the early solar system. Also; discovery of a red supergiant with a neutron star in its core, and scientists may have captured the first particles from interstellar space.
Birth of solar system triggered by dying giant?
A red giant star rather than a supernova may have triggered the birth of the Sun and solar system. Also; hurricanes on Earth producing gamma-rays that are picked up in space, and over 100 geysers observed on Saturn's ice moon Enceladus.
Rosetta reaches its comet
Rosetta becomes the first spacecraft to orbit a comet. Also; NASA prepares its next Mars rover mission as Opportunity sets a new distance record, and early Earth may have been habitable.
