STARDUST MEMORIES; Beautiful, Astonishing Picture of the Oldest Light in the Universe Showing Stars Being Born 14billion Years AgoThe Mirror (London, England)
SOFIA detected helium hydride, a combination of helium (red) and hydrogen (blue), which was the first type of molecule to ever form in the early universe. This is the first time helium hydride has been found in the modern universe.NASA/ESA/Hubble Processing: Judy Schmidt...

Astronomers are on the hunt for traces of gold on the surfaces of some of the oldest stars in the universe in order to find the origins of heavy metals in the cosmos. A new study uses numerical simulations of star formation in galaxies dating all the way back to the Big Bang to unloc...
The Role of Spiral Structures “Spiral structures are rare in the early Universe, and exactly how they form also remains unknown. This study also gives us crucial information on the most likely scenarios. “While it is impossible to observe the galaxy’s evolution directly, as our observation...
Active galactic nuclei inject large amounts of energy into their host galaxies and surrounding environment, shaping their properties and evolution1,2. In particular, active-galactic-nuclei jets inflate cosmic-ray lobes, which can rise buoyantly as light ‘bubbles’ in the surrounding medium3, displa...
archaeologist, used a technique he developed to date the painting that its importance was revealed. He found that it is staggeringly ancient: at least 35,400 years old. That likely makes it the oldest-known example of figurative art anywhere in the world—the world’s very first picture. ...
The discovery of the oldest star map has also revealed star coordinates, meaning Hipparchus was the first to use them for determining the positions of those stars.
This laser-focus indicates more clearly how light has extended into the infrared band, because it breaks down the light into its component wavelengths. The breakdown also provides a clearer picture of the spectra, or colors within the light, which disclose information about the object’s ...
