How galaxies change the look of the universe09/01/15
Galaxy evolution shows a dramatic drop in the ratio of spiral to elliptical galaxies. Also; astronomers find a nearby quasar powered by two supermassive black holes, and red sprites at night prove to be an astronaut's delight.
How Jupiter was made
The king of planets may have formed from pebbles. Also; Don't panic! Asteroid won't hit Earth next month, says NASA, and studies narrow down the candidates in the search for dark energy and dark matter.
Colliding galaxies found next door
Astronomers have discovered a spectacular galactic collision hidden on the other side of the Milky Way. Also; smallest planet ever directly seen beyond our solar system, and plans for a space elevator capable of reaching into the stratosphere.
A galaxy in the making
Astronomers believe they've seen the first evidence of galactic birth. Also; the most detailed look yet at when the universe will end, and a new record for the most distant galaxy ever seen.
Earth's magnetic field much older than we thought
Ancient minerals push back the age of Earth's magnetic field by more than 800 million years. Also; first auroras detected beyond our solar system, and Rosetta's Philae lander reveals its comet's secrets.
Glaciers could explain Pluto's young surface
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.
