New research based on observational data from the Spitzer telescope provides clues as to how the universe first emerged from its dark age.
- Researchers using the Spitzer telescope were able to analyze some of the most distant and ancient galaxies in the universe.
- They discovered that these galaxies were far brighter than anticipated, shedding clues into how the universe first emerged from the "dark ages" that lasted until about a billion years after the Big Bang.
- This research serves as a stepping stone for future work to be conducted with the James Webb Space Telescope, scheduled to be launched in early 2021.
A new NASA report shakes up lunar geology.
- The moon is indeed shrinking. It has been since it formed.
- The shrinking is producing thousands of fault lines.
- Archived seismometer data from Apollo missions show moonquakes.
The answer is surprisingly simple, if cataclysmic.
- A unique, tiny grain of stardust has provided a look at the early universe.
- Computer simulations point to a single neutron-star collision as a significant source of heavy metals.
- Gold is more than bling — it's in our neurons.
What if all planets were the same distance from Earth as the Moon?
- A video imagines what it would look like if the planets were all the same distance from Earth as the Moon.
- The largest planets like Jupiter and Saturn would loom large in the sky.
- Mercury is the smallest planet in the solar system.
A tiny grain found within a meteorite in Antarctica sheds light on how the solar system itself came to be.
- Researchers cut open a small meteorite found in the LaPaz icefield in Antarctica to uncover a very surprising find.
- Inside this meteorite was a small inclusion that they determined came directly from the nova of a white dwarf to Earth.
- By studying the inclusion's composition, researchers were able to glean new insights into the thermodynamics of white dwarf novae, ultimately shedding light onto how solar systems like ours formed.
