New way to probe primordial universe before the big bang

Most everybody is familiar with the Big Bang — the notion that an impossibly hot, dense universe exploded into the one we know today....
Image of planetary nebula NGC 7027 with illustration of helium hydride molecules. In this planetary nebula, 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. Credits: NASA/ESA/Hubble Processing: Judy Schmidt

The universe’s first type of molecule is found at last

The first type of molecule that ever formed in the universe has been detected in space for the first time, after decades of searching....

What happened before Big Bang?

The Big Bang hypothesis is a push to clarify what occurred at the very beginning of our universe. Revelations in astronomy and physics have...

Wonderful!! 83 supermassive black holes found in the early universe

Supermassive black holes, found at the centers of galaxies, can be millions or even billions of times more massive than the sun. While they...
NASA's Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) mission is targeted to launch in 2023. SPHEREx will help astronomers understand both how our universe evolved and how common are the ingredients for life in our galaxy’s planetary systems. Credits: Caltech

NASA now wants to explore the origin of the Universe

In a new mission, NASA has decided to explore the origin of the universe- solving a long term mystery- how our universe evolved and how...
Universe's stuff keeps changing

Universe’s stuff keeps changing

The piece of the universe—the components that are the building blocks for all of matter—is consistently changing and regularly evolving, on account of the...
Simulation of galaxies and gas in the universe. Within the gas in the (blue) filaments connecting the (orange) galaxies lurk rare pockets of pristine gas – vestiges of the Big Bang that have somehow been orphaned from the explosive, polluting deaths of stars, seen here as circular shock waves around some orange points.

Astronomers discovered pristine, uncontaminated material existing at the beginning of the universe

Astronomers have recently discovered a relic cloud of gas, orphaned next to Big Bang in the distant universe. The discovery of such a rare...
The new discovery is only 14% the size of the Sun and is the new record holder for the star with the smallest complement of heavy elements. It has about the same heavy element complement as Mercury, the smallest planet in our solar system./By Kevin Schlaufman/JHU.

Johns Hopkins scientists may have found one of the universe’s oldest stars

Astronomers at the Johns Hopkins University have discovered what could be one of the universe's oldest stars, a body on the whole made of...
The first detector antenna-coupled, transition-edge superconducting arrays developed for 40 GHz on 150-mm diameter wafers for larger formats. The array is shown mounted in a test focal-plane assembly.

Exploring the birth of the universe with large-format detector arrays

Examining the quantification of the universe rapidly expanded in a burst called “inflation” moments after the Big Bang. To do so, NASA scientists are developing ultra-sensitive...
