'Comets are ancient leftovers of early solar system', reveals study

Comets are the ancient leftovers of early solar system formation, and not younger fragments resulting from subsequent collisions between other larger bodies, according to a new study of data collected by the Rosetta space probe.

Must watch – What would happen if an asteroid hit the Earth today!

Must watch – What would happen if an asteroid hit the Earth today!

 Although the Earth is constantly being hit with with asteroids that entered and disintegrated in its atmosphere, life has survived the impact and lived through each crisis today.

Giant comets may pose danger to life on Earth

Known severe upsets of the terrestrial environment and interruptions in the progress of ancient civilisations, together with our growing knowledge of interplanetary matter in near-Earth space, indicate the arrival of a centaur around 30,000 years ago.

Astronomers conclude bizzare star KIC 8462852 swarmed by comets

NASA’s Spitzer Space Telescope suggest that the unusual light signals coming from a star called KIC 8462852 are likely coming from dusty comet fragments swarming around it.

Doomsday is not near, NASA reassures amid collision rumours

Doomsday is not near, NASA reassures amid collision rumours

 A giant asteroid - around 2.5 kms in diameter - is heading towards Earth. An asteroid of its size has the potential to cause global devastation if it was to hit Earth, but NASA said the space rock poses no danger to us.

NASA's new spacecraft may hitchhike across galaxy

NASA scientists have designed the concept of a spacecraft that would hitch rides on comets and asteroids by spearing them with tethers.

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

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.

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.
