HOW TO COMET NEOWISE before disappearing for thousands of years


There is still little time to get a glimpse of a newly discovered comet as it blooms in the night sky, especially if you have a telescope or telescope work.

The C / 2020 F3 NEOWISE, also known as Comet NEOWISE, was first spotted by NASA’s Near-Earth Object Wide-Field Infrared Survey Explorer (NEOWISE) mission in March later this year. According to NASA, the comet’s nucleus is about 3 miles in diameter from the birth of our solar system about 4.6 billion years ago and is made up of dust, rock, and gases.

When comets near our sun, the rising heat creates a coma or a type of atmosphere that is made up of particles and gases around the nucleus. A combination of solar wind and sunlight pressure can blow some of the atmosphere away from the comet, forming two tails – one made of ions, and the other made of dust – that is in the opposite direction of the sun for millions of miles. Can spread to Imaging suggests that comet NEOWISE may possibly have two ion tails as well as its dust tail.

Joseph Macario, who serves as Deputy Principal Investigator of NEOWISE at NASA’s Jet Propulsion Laboratory, said the comet NEOWISE was on display as “exhilarating”, specifically that it was reported for the comet How rare it is that passing through our planet is visible with the naked eye.

“I’m pretty sure that every astronomer surveying the sky has a secret hope to find the next naked-eyed comet, so it seems to me that our team has won the lottery on it,” Maciro said. “These kinds of astronomical events really help remind me how big and amazing the universe is, and how lucky I am to find it in these hard times.”

Comet NEOWISE made its closest approach to the Earth on 22 July and it became dim and dimmed as it returned to the outer reaches of our solar system. But if you want to try your luck in the next few days, find a patch of sky with a minimal amount of light pollution, where your viewpoint will not be obstructed by trees or buildings.

Then look down at the northwest sky and a little west of the Big Dipper – the comet must have been climbing above the horizon as the nights would have been. You can use the Comet NEOWISE app to help you find out exactly where to look for a comet from your location.

Although you can still see Comet NEOWISE with your naked eye, a pair of binoculars or binoculars should give you a clear view. The publication EarthSky also recommends using a high-quality camera that can capture comets with extended exposure.

If you miss the show this time, all you have to do is wait another 6,800 years or so for Comet NEOWISE to make it back to Earth.
