Glaciers could explain Pluto's young surface07/28/15
Glaciers on the surface of Pluto could explain the mysterious frozen world's youthful skin. Also: most Earth-like planet ever found orbiting a Sun-like star, and more support for the Standard Model of particle physics.
Pluto up close
Icy mountain ranges and vast frozen plains dominate a geologically young surface on Pluto. Also; dead galaxies saved by dark matter, and a new 100-million-dollar effort to try an answer that eternal question: are we alone in the universe?
New Horizons becomes the first spacecraft to visit Pluto. Also monster black hole grows surprisingly faster than its ancient galaxy, and physicists at CERN discover a new particle: the 'pentaquark'.
New Horizons stays on track for Pluto
Despite a glitch earlier this week, New Horizons is on course for its historic rendezvous with Pluto. Also; mystery circles on Pluto's surface baffle scientists, and new calculations claim an earlier more violent end to the universe.
Alien planet in comet's clothing
Astronomers discover a planet that looks like a comet. Also; how magnetic fields could help to form a galaxy's spectacular spiral arms, and Earth hit by two geomagnetic storms in a week.
Early stars captured in historic image
Astronomers observe what could be some of the first stars to form after the Big Bang. Also: evidence for current volcanism on Venus, and new signs of methane from Mars.
Rosetta's comet lander Philae finally phones home
Scientists finally make contact with Rosetta's long lost comet lander Philae. Also: how Albert Einstein saved Erwin Schr�dinger's cat, and the solar system's biggest ring is far bigger than thought.
Could we find gravitational waves this year?
Evidence of gravitational waves may be in our reach by the end of the year, says scientist. Also; Pluto's small moons tumble in constant chaos, and Hubble detects the first intergalactic supernovae.
New Horizons on target for first Pluto encounter
New Horizons now on its final approach to Pluto. Also: New limits set on the quantum nature of space and time, and the Large Hadron Collider sets a new collision energy record.
Supernovae origins: both theories are right!
Astronomers confirm thermonuclear supernovae can be caused by one or two white dwarfs. Also: discovery of the brightest galaxy ever seen, and alien stars found in our galaxy.
Philae! Phone home!
Scientists still waiting for Rosetta's comet lander Philae to phone home. Also; a new explanation for the dominance of matter over antimatter, and CERN physicists confirm the neutral B meson sub atomic particle exists.
Mercury's magnetic field is four billion years old
Mercury has the oldest observed magnetic field in the solar system. Also; the most distant galaxy ever discovered, and a massive halo detected around Andromeda.
Mystery fog may be the screams of zombie stars
A mysterious high energy X-ray fog could point to a vast stellar graveyard. Also; new images of Pluto indicate a possible polar ice cap, and the strange exo-world that challenges theories about how planets are made.
Messenger set to crash onto Mercury
Messenger's historic mission to the planet Mercury about to end. Also: New clues about the very first stars to shine in the Universe, and a massive magma chamber discovered deep under the Yellowstone supervolcano.
Hubble celebrates 25 years of science
How the Hubble Space Telescope has expanded our view of the Universe. Also: mystery of largest structure ever identified by humanity solved, and meteorites pinpoint the exact age of Earth and the Moon.
Liquid water possible on Mars
Studies show present day liquid water could exist on Mars. Also; The first potential signs of dark matter interaction, and the mystery deepens for NASA's Dawn mission to the dwarf planet Ceres.
Hot model explains how Jupiter survived
New computer simulations may show how Jupiter saved itself from falling in to the Sun. Also; vast populations of newborn stars discovered in the galactic halo, and new plans to mine the Moon for mineral riches.
Ghostly dark matter rewrites the rules
New studies show dark matter doesn't seem to interact with anything, not even itself. Also; NASA's plan to pluck a boulder off an asteroid and put it in orbit around the Moon, and nitrogen discovered on Mars.
Largest asteroid impact zone found in Australia
One of the largest asteroid impact zones on Earth discovered in outback Australia. Also; how Jupiter could be responsible for the formation of planet Earth, and sky watchers given a triple treat with a spectacular supermoon equinox eclipse.
Hot springs on Saturn moon
Evidence of hot springs discovered on the Saturnian moon Enceladus. Also; the Milky Way at least 50 per cent bigger than previously thought, and a new population of dwarf satellite galaxies discovered orbiting the Milky Way.
