A comet will shine above the earth for weeks and we will not see him again 6800 years ago

NASA telescope “New Wise”, which Infrared worksThe new comet last March, which was shared with the same name, and the scientists participating in the mission said that the width of the comet is about 5 kilometers, and its nuclei are covered with a sooty substance dating back to the origin of our solar system 4.6 billion years ago..

And led near The culprit New Wise From the sun To the combustion of dust and gas surrounding its surface and the appearance of a tail larger than debris, and it is on its way to us now, as it will reach the nearest point of Earth After two weeks.

Other offenders this year have shown promising signs of a brilliant appearance in the sky, but their rays faded later. According to astronomers, New Wise will be the most prominent culprit this year, and will offset the failures of other comets.

When can be seen in the sky?

Seeing the New Wise comet represents a historic opportunity that will not be repeated for us to see, as it will not return to our inner solar system until after 6800 years.

Currently, it can only be seen in the early morning an hour or two before sunrise the sun In the northeastern sky.

This may mean waking up at 4 am local time to see it, before the comet disappears in broad daylight.

The US space agency said “NASA: From mid-July onwards, it is best to see it as an evening object, which is increasingly rising over the northwestern horizon.

She added: “His closest approach to Earth will be on July 22nd, at a distance of about 103 million km. For comparison, the sun is about 150 million km from Earth.”

How does it look?

Many comet photos have spread on Social media Imagine it as a shiny object filling an area of ​​the sky, but for the naked eye, it might look just a mysterious star and a faded tail.

However, it could be revealed The telescope Or a simple telescope with more detail, especially when seen before twilight in the morning or after twilight in the evening.

Several photos were taken The culprit “New Wise” with the technique of imaging for long periods, and using cameras with the technique of zoom and zoom that were used at maximum capacity on the comet.

According to “Ubay”, the comet will add a dazzling light feature in the sky, but it will not be as impressive as the 1997 “Bob Hill” comet, which appeared larger and was clearly visible.

Brightness strength
Astronomers measure the brightness of objects in the night sky using a measure known as magnitude or “magnitude.”

The lower the amount given to the celestial body, the brighter it will be in the sky, so that it is visible to the naked eye.

For example, it is an amount The brightness of the moon 12- Degree, for the object to be visible with the naked eye, it must be 5 or 6.

As of Wednesday, the amount of comet “New Wise” was 1.6, according to SkyLife, a website that provides real-time data on the brightness of things in the night sky.

As for guilty?Haley Bob“The famous hit it degree 0, and it was visible for a whole year above the earth.
