Cosmic collision creates mini-planet with rings

Until now, rings of material in a disc have only been observed around giant planets like Jupiter, Uranus, Neptune and especially Saturn, which is known for its spectacular rings.

Magnetic ‘force field’ shields giant gas cloud during collision with Milky Way

Doom may be averted for the Smith Cloud, a gigantic streamer of hydrogen gas that is on a collision course with the Milky Way Galaxy. Astronomers using the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) and Robert C. Byrd Green Bank Telescope (GBT) have discovered a magnetic field deep in the cloud’s interior, which may protect it during its meteoric plunge into the disk of our Galaxy.

Chelyabinsk meteorite had previous collision or near miss

The Chelyabinsk meteorite either collided with another body in the solar system or came too close to the Sun before it fell to Earth, according to research announced today (Tuesday 27th August) at the Goldschmidt conference in Florence.

Did cosmic collision flood medieval Earth with gamma rays?

Astronomers believe they've worked out the source of a mysterious burst of gamma rays that irradiated the Earth in the 8th century.

Asteroid Apophis passes safely past Earth

The massive asteroid Apophis shot past Earth last night, on a trajectory that will bring it even closer during its next flyby in 2029.

Vesta 'stretch marks' suggest it's a stunted planet

Enormous troughs that encircle the asteroid Vesta may be faults that formed when another asteroid smacked into its south pole, and indicate that it has the same type of interior as a planet.

Milky Way set for head-on crash with Andromeda galaxy

Look out: we're headed for a crash. In, ooh, just four billion years or so our Milky Way galaxy is set to collide with neighboring Andromeda.

Moon 'wasn't created by giant collision'

A new chemical analysis of lunar material collected by Apollo astronauts in the 1970s appears to disprove theories that the moon was created through a massive collision between Earth and a Mars-sized object 4.5 billion years ago.

Dark matter core remains an enigma



Astronomers analyzing data from NASA's Hubble Telescope have identified what seems to be a clump of dark matter left behind from a collision between massive clusters of galaxies.

Galactic collisions shaped Milky Way

UC Irvine astronomers have shown how the Milky Way galaxy's iconic spiral arms were formed - through an intergalactic collision.

Earth once had a second moon

The Earth once had two moons circling in the same orbit, say scientists, until a collision between the two created the moon we see today.

Massive cosmic car crash revealed

Astronomers are studying what they decribe as one of the most complex and dramatic collisions between galaxy clusters ever seen, and which has taken 350 million years to play out.

Scientists ready to study Earth-buzzing asteroid

Imagine looking up into the sky and seeing a giant asteroid the size of an aircraft carrier. Scary, eh? But don't worry, because although scientists predict the fly-by will happen this fall, they aren't concerned about a possible collision.

Physicist plans asteroid deflection system

Lasers could be used to deflect asteroids on potential collision courses with Earth, according to a new study.

LHC starts new set of experiments

The Large Hadron Collider is about to enter a new phase of operation, with proton running for this year concluding successfully this morning. For the rest of the year, lead ions will be accelerated and brought into collision in the machine for the first time.

Recent asteroid collision caught on camera

Astronomers have spotted what's been confirmed as a collision between two asteroids that took place just last year beyond the orbit of Mars.

Hazardous asteroid on potential collision course with Earth

A dangerously large asteroid could hit the earth in 2182 - and it needs to be deflected by 2080 at the latest, according to a global research team.

Ground-based laser system to track space junk

An Australian company is to build the world's first automated laser system to track dangerous space junk.

New Air Force satellite to monitor space junk

The US Air Force will this week launch a satellite designed to monitor the skies for dangerous debris.
