Science behind comets' formation revealed

In a recent study, the Rosetta's target 'Chury' and other comets observed by space missions have shown a common evidence of layered structures and bi-lobed shapes.

Comets are like deep-fried ice cream: Indian-origin scientist
Comets are like deep-fried ice cream: Indian-origin scientist

Using an icebox-like instrument nicknamed Himalaya, an Indian-origin researcher-led team has revealed that fluffy ice on the surface of a comet would crystallise and harden as the comet heads toward the Sun and warms up.

A new theory has indicated that humans could be wiped out by two dwarf stars that will drop a torrent of comets onto Earth.

Rosetta suggests Earth`s water came from asteroids, not comets
Rosetta suggests Earth`s water came from asteroids, not comets

Water on Earth is more likely to have come from asteroids that hit our planet billions of years ago than comets, European researchers said on Wednesday.

Comets smell like rotten eggs, horse urine
Comets smell like rotten eggs, horse urine

The smell of comets is quite strong, with the odor of rotten eggs (hydrogen sulphide), of horse stable (ammonia) and the pungent, suffocating odor of formaldehyde, it has been revealed.

Deadly virus from space may have played role in earlier extinctions

A new study has revealed that a super-virulent virus, which either came from space or were supercharged by particles brought to Earth on comets, was most likely responsible for killing the dinosaurs.

Rosetta enters 67P`s neighborhood as the comet starts taking shape

The current images acquired by European Space Agency`s spacecraft Rosetta the nucleus of 67P/Churyumov-Gerasimenko covered a good four pixels.

Interplanetary dust jump-started life on Earth?

Dust coming from comets and asteroids may have delivered water and organics to the Earth - jump starting life on our planet, US researchers say.

In 2014, get answers to your comet queries

Seven interesting facts about meteors

A meteor shower is truly a celestial delight to watch. A meteor basically refers to a bright trail of light that appears in the dark sky when a tiny chunk of space debris heats up and burns due to friction caused by the earth’s atmosphere.

Lasers may be key to nudging small asteroids away from Earth

Researchers have proposed a space-based laser system to NASA that could turn out to be a cost-effective way to nudge small asteroids away from a collision course with Earth.

New method that predicts changes in comets` rotational states identified

Researchers have discovered a new method that can help them predict the changes in the rotational states of comets.

ESA`s space probe to reveal mysteries of comets

ESA`s space probe Rosetta, which is supposed to rendezvous, next spring, with comet Churyumov-Gerasimenko, is set to reveal many mysteries about comets.

Graveyard of comets discovered in asteroid belt between Mars and Jupiter

Astronomers from the University of Antioquia, Medellin, Colombia, have discovered a graveyard of comets in the asteroid belt between the orbits of Mars and Jupiter.

Centaurs may actually be comets, not asteroids

A new study of observations from NASA`s Wide-field Infrared Survey Explorer (WISE) has revealed that most centaurs - the small celestial bodies orbiting the sun between Jupiter and Neptune - are actually comets.

Study of Solar system`s youth could aid search for new planets

Comets and meteorites contain clues to our solar system`s earliest days, even though some of the findings don`t fit well together.

ALMA discovers comet factory, solves planet formation mystery

Computer models suggest that dust grains grow when they collide and stick together. However, when these bigger grains collide again at high speed they are often smashed to pieces and sent back to square one.
