Comets, the frozen leftovers from the formation of the Solar System, are one of the biggest attractions for stargazers and astronomers across the world. A new study reveals that scientists can detect meteor showers from the debris in the path of comets that pass close to Earth s orbit. ....

Iron and nickel vapours found in cold atmosphere of comets for first time

Iron and nickel vapours found in cold atmosphere of comets for first time
‘It was a big surprise to detect iron and nickel atoms in the atmosphere of all the comets we have observed in the last two decades .
19 May, 2021 15:00
Scientists have spoken of their “big surprise” after discovering iron and nickel vapours in the ultra-cold atmosphere of comets for the first time.
These heavy metals are usually associated with hot environments, but astronomers found atoms of nickel and iron in the clouds of dust and gas surrounding distant comets, more than 480 million kilometres from the Sun (about three times the distance between the Earth and the Sun). ....

What Does a Meteor Shower Look Like? What Time Is Best to See the Eta Aquariids

What Does a Meteor Shower Look Like? What Time Is Best to See the Eta Aquariids
On 5/5/21 at 12:39 PM EDT
The Eta Aquariids meteor shower has reached its peak, but what should skygazers look out for and when is the best time to watch?
Meteor showers are celestial events during which several meteors appear to originate from a single point in the night sky known as the radiant. These events take place when the Earth passes through streams of cosmic debris left behind by comets and, in rare cases, asteroids.
Meteors are the streaks of light we see in the sky when tiny fragments of space debris enter the Earth s atmosphere and burn up at high speed. These streaks of light are popularly referred to as shooting stars. ....

Earth receives tonnes of dust each year, thanks to asteroids

Every year, over 5,000 tonnes of extraterrestrial dust fall to Earth each year, scientists have determined. Our home planet encounters dust from comets and asteroids. These interplanetary dust particles pass through our atmosphere and give rise to shooting stars. Some of them reach the ground in the form of micrometeorites. ....
