The heavens are expected to declare even more of God’s glory1 this week. Probably early Wednesday morning, the Lyrid meteor shower will peak.2 For those who are socially isolated due to the coronavirus pandemic, this event is an opportunity to enjoy a little more of God’s creation, as well as a reminder that our solar system is young.
As comets approach the sun, they lose material as ices in the comet nucleus vaporize. Sometimes bits of material break off the comet nucleus. Meteor showers occur when the Earth’s orbit passes through high concentrations of debris in a comet’s orbital path. As these cometary fragments enter our atmosphere at very high speed, they burn up, causing “shooting stars.”
The Lyrid meteor shower occurs every year around April 16-25 when the Earth passes through debris from one particular comet, Comet Thatcher. Those who want to see these “shooting stars” should watch the late evening to pre-dawn skies starting Sunday evening, April 19. The shower peak is expected in the very early (pre-dawn) hours on Wednesday, April 22, but it is possible that the Lyrids may also put on a good show the following evening.
For those wanting to view this meteor shower, astronomers recommend, that you find a viewing location with dark skies away from city lights, if possible. You may still see some meteors even with light pollution, but the show will likely be much better if you are aware from the city lights. Also, they recommend patience and, frankly, not getting your expectations too high! Under ideal conditions, you might see 10-15 meteors per hour, although outbursts have been known to occur, with as many as 100 meteors per hour.2
Meteor showers are a reminder that comets have finite lifetimes due to their loss of material.3-5 Most comets can only remain visible for thousands of years. Secular astronomers think comets are “leftovers” from the solar system’s formation billions of years ago. But if comets only last thousands of years, then how can we still have comets in a solar system that is billions of years old?
Secular astronomers argue that “reservoirs” re-supply the solar system with new comets to replace those that are no longer visible. However, there are problems with this idea. For instance, Comet Thatcher is a long-period comet6 that is supposed to originate from a hypothetical reservoir of comet nuclei called the Oort Cloud. However, even the late astronomer Carl Sagan acknowledged that there was not a shred of direct evidence for this hypothetical Oort Cloud.7 Also, because comets are supposedly “leftovers” from the solar system’s formation, they would have had to “migrate” outward in order to form and populate the Oort Cloud. Yet computer simulations have shown that most of the comet nuclei would have smashed into each other and been destroyed during this outward migration process!8
So if you and your family are looking for something fun to do, look to the evening skies this week!
