For years, astronomers have tried to explain how stars known as blue stragglers can look so young.

Blue stragglers are stars that appear very hot and bright and often found in star clusters thought to be very ancient.  The degree of their brightness and temperature are strong indicators that blue stragglers are relatively young stars.

However, you know that secular evolutionary astronomers can’t have a young star in the center of an ancient star cluster.  It has to be billions of years old based upon their presuppositional beliefs.

Over the years, they have developed a number of possible explanations.  Those ideas range from:

  • The blue straggler having formed much more recently than the rest of the star system.
  • They don’t actually belong to that star system even though it appears that way.
  • They are younger stars that were captured by the star system.
  • They are the result of a collision with another star or similar object.

There are major problems with most of these explanations and very little observational evidence to support any of them.  So a team of researchers from Northwestern University and the University of Wisconsin-Madison have proposed a new explanation that they claim answers the major questions raised by the other scenarios.

The team points out that a number of blue stragglers are found in binary systems – systems having two stars.  They purport that the blue stragglers draws off the outer envelope of the larger member of the binary star system giving them more energy and material to burn and leaving the other star as a white dwarf.

Have you ever heard of the small constellation known as Cepheus?  It’s located in the northern skies near Polaris, the North Star.  The scientists studied an open cluster in the system known as NGC 188 that contains about 3,000 stars and 21 blue stragglers.

They could not see the light from the companion stars to the blue stragglers but knew they were there because of the wobble of the blue straggler as it orbits.  Based upon the size of the blue straggler and the degree of gravitational wobble, they calculated the size of the companion star.

From their observations, Drs Geller and Mathieu concluded that the only theory that made any sense was the one involving the blue straggler sucking the energy away from the companion star.  They are also planning to use the Hubble Space Telescope over this next year to see if they can actually see the companion stars.  If the companions are white dwarfs as they theorize, then they should be able to detect them in the ultraviolent range.

Dr Geller said that it is often the unseen objects in space that provide the critical clues in astronomy.

I’m not an astronomer nor do I understand all of the astrophysics involved in the field, but I do know that none of the stars are as old as astronomers claim, nor did they just evolve from compressed stellar gases.  That’s why I rely on astronomers and astrophysicists like Dr. Russ Humphreys, Dr. John Hartnett, Dr. Danny Faulkner and Dr. Jason Lisle to help me make sense of the many mysteries found in astronomy.  All of these men believe in a young universe and young creation as described in Genesis 1.  I strongly suggest you check out some of their books and videos found in our bookstore.

Creation Astronomy (DVD)

Genesis teaches that God created the entire universe supernaturally, only thousands of years ago. Yet, most people are convinced that the universe started in a big bang billions of years in the past. In this illustrated lecture, astronomer Dr. Jason Lisle shows viewers that when the evidence of nature is understood properly, it lines up perfectly with the clear teachings of Scripture. The heavens declare the glory of God!
