Universe’s 1st Objects After Big Bang Possibly Seen by NASA Telescope
New observations from a NASA space telescope have spotted what may be the very first objects created in the universe in unprecedented detail, scientists say.
The faint objects, imaged in infrared light by NASA’s Spitzer space telescope, might be hugely massive stars or black holes, but are too distant to see individually.
The Big Bang is thought to have kick-started the universe about 13.7 billion years ago. At first, the universe was too hot and dense for particles to be stable, but then the first quarks formed, which then grouped together to make protons and neutrons, and eventually the first atoms were created. After about 500 million years, the first stars, galaxies and black holes began to take shape.
