Comet Now Visible to the Naked Eye
Stargazers have been disappointed earlier this year by comets ATLAS and SWAN, which disintegrated before they could put on good celestial shows. But another comet is now appearing in the sky and delighting stargazers.1,2

This comet has been dubbed NEOWISE, because it was discovered by the Near-Earth Object Wide-Field Infrared Survey Explorer (NEOWISE) space telescope in March. Although the comet might be visible to the naked eye, you may need a pair of binoculars first to find it, and then to observe the comet’s two tails.1 However, it might be possible to see the comet even under less-than-ideal conditions. One creation astronomer was able to see the comet even with a bright moon and light-polluted skies.3

Comet NEOWISE now is putting on a good show in both the low, northeastern, pre-dawn sky and the low, northwestern, evening sky. However, starting next week, viewing should be best in the evening.4 If the comet survives, it will make its closest approach to Earth around July 22 or 23 when it could present a good view for observers.2

Comet NEOWISE last approached the Earth about 4,500 years ago, which means it could have been seen by biblical patriarchs like Noah!3

Comets with orbital periods of greater than 200 years are called “long period comets,” and secular astronomers claim they originate from an enormous reservoir of billions of potential comet nuclei called the Oort cloud. However, even the famous secular astronomer Carl Sagan acknowledged that there was zero observational evidence for the Oort Cloud’s existence.5 Secular scientists hypothesize the Oort cloud’s existence because they realize that comets typically only remain visible for thousands or tens of thousands of years. After this amount of time, their volatile materials are exhausted, and they can no longer form the long, beautiful tails for which they are famous. Since secular scientists think the solar system is billions of years old, they believe that this reservoir of potential comet nuclei must continually replenish the solar system with new long-period comets. Creationists, on the other hand, point out that an Oort cloud really isn’t necessary if the solar system is just 6,000 years old.

The lack of evidence for the Oort cloud is only its most obvious problem. In 2010, secular scientists acknowledged that, even if the Oort cloud exists, it can’t provide enough long-period comets to keep our solar system “stocked” for billions of years.6 Perhaps for this reason, scientists have made major revisions to the theory. However, like the Oort cloud itself, this newer version of the theory is highly speculative, with no hard evidence to back it up.6,7

In 2010, NASA’s Deep Impact spacecraft provided even more dramatic evidence that comets are young.8 Its observations of the peanut-shaped Comet Hartley 2 showed that carbon dioxide is escaping from the comet nucleus. This shocked secular scientists.

[Comet Hartley 2’s] nucleus contains an abundance of carbon dioxide (CO2—or, in solid form, dry ice). This is a volatile material—it burns [or “vaporizes”] easily—and so scientists would expect much more of it to have burned away in the 4.5 billion years since the comet formed along with the rest of the solar system.9

Of course, if Comet Hartley 2 is just thousands of years old, rather than billions, its continued loss of carbon dioxide is much easier to explain.10

So may the Lord grant you clear skies in the weeks ahead so that you can get a good look at Comet NEOWISE. And remember, comets are a reminder that our solar system is young!
