SUMMARY

A giant space "blob," named Himiko, was discovered by astronomers using both space and ground telescopes, dating back to when the universe was approximately 800 million years old. This gaseous formation emits a specific type of radiation, leading to significant intrigue among scientists. The discovery raises questions about its alignment with cosmic microwave background (CMB) anisotropies and the limitations of observing the early universe, particularly the opaque period when atoms could not transmit electromagnetic radiation. Further observations are necessary to understand the implications of this finding.

PREREQUISITES
  • Understanding of cosmic microwave background (CMB) anisotropies
  • Familiarity with astronomical observation techniques using space and ground telescopes
  • Knowledge of the early universe's opacity to electromagnetic radiation
  • Basic concepts of gravitational waves and neutrino physics
NEXT STEPS
  • Research the implications of cosmic microwave background (CMB) anisotropies on early universe observations
  • Study the methods used in astronomical observations with space telescopes like Hubble and ground-based observatories
  • Explore the physics of gravitational waves and their potential to probe earlier epochs of the universe
  • Investigate the properties and significance of radiation-emitting gaseous formations in cosmology
USEFUL FOR

Astronomers, astrophysicists, and students of cosmology interested in the early universe and the implications of recent astronomical discoveries.

WASHINGTON - A strange giant space “blob” spotted when the universe was relatively young has got astronomers puzzled.

Using space and ground telescopes, astronomers looked back to when the universe was only 800 million years old and found something that was out of proportion and out of time. It was gaseous, big, and emitted a certain type of radiation, said study lead author Masami Ouchi, an astronomer at the Carnegie Observatories in Pasadena, Calif.

Scientists don’t even know what to call it. So they just called it a radiation-emitting “blob.”...

It is an interesting discovery. Only further observation will tell the tale.

Got to love a good blob.

"More formally, they named it Himiko, after a legendary ancient Japanese queen."
Drats, I don't like that name.
 
If this thing is so young, would there be any expectation of it "lining up with" an anisotropy in the CMB?
 
Now why don't they look a little further back in time to see the big bang :)

They do look further back, but there was an epoch in time when atoms were opaque to EM radiation. This is a cut off point. You can't see any further back than that (so you can't actually see the big bang).
 
The early universe was only opaque to em radiation, neutrinos could push the limit much further back, and gravity waves - perhaps all the way back.
