Time Traveling With Spitzer

 

Written by Nancy Atkinson

While time travel is seemingly impossible, we can actually look back in time with our telescopes to learn about the conditions of our universe in times past. The Spitzer Space Telescope has found some very dim and distant galaxies located at the edge of our universe that have never been seen before. Approximately 12.5 billion light-years away from Earth, we’re seeing these galaxies as when our universe was just one billion years old. With Spitzer's infrared capability, astronomers have been able to take infrared portraits and even "weigh" many of these early galaxies. "Understanding the mass and chemical makeup of the universe's first galaxies and then taking snapshots of galaxies at different ages, gives us a better idea of how gas, dust and metals– the material that went into making our Sun, solar system, and Earth –has changed throughout the Universe's history," said Spitzer scientist Dr. Ranga Ram Chary.

Unlike the galaxies of today, Chary says that galaxies living in the one billion year old universe were much more pristine. They were comprised primarily of hydrogen and helium gas and contained less than 10% of the heavier elements we see in the local Universe today, and even on Earth. Astronomers have found these distant galaxies were cosmic "lightweights", or not very massive compared to mature galaxies we see nearby.

"A few billion years after the big bang, 90 percent of the stars being born were occurring in these types of faint galaxies. By identifying this population, we hope to gain insights into the environments where the universe's first stars formed," said Chary.

To find these faint galaxies, astronomers followed the lingering afterglow of gamma ray bursts back to their sources. Astronomers believe gamma ray bursts appear when a very massive star dies and becomes a black hole.

The afterglow occurs when energetic electrons spiral around magnetic fields, and release light. In its explosive death, material shooting out of the massive star smashes into surrounding gas. This violent collision heats nearby gas and energizes its electrons.

Once coordinates of the faint galaxies were determined, Chary's team then used Spitzer's supersensitive infrared array camera to snap a picture of the faint galaxy. The amount of light from the galaxies allowed Chary to find the mass of the galaxies.

Biography

Since 1962 I doubted on Newton's laws. I did not accept the infinitive speed and I found un-vivid the laws of gravity and time.

I learned the Einstein's Relativity, thus I found some answers for my questions. But, I had another doubt of Infinitive Mass-Energy. And I wanted to know why light has stable speed?
