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

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 Cosmic Microwave Background (CMB) radiation could aid scientists to get deep insights on how the universe rapidly expanded in a burst...

Astronomers found evidence for stars forming just 250 million years after Big Bang

Atacama Large Millimeter/submillimeter Array (ALMA) and ESO’s Very Large Telescope (VLT) have captured the evidence on star formation in the very distant galaxy MACS1149-JD1 suggesting that...

The other side of the Big Bang

Big Bang is considered as the beginning of our universe. According to the latest study by the Oxford University Earth’s universe actually existed before...
Artist's rendering of the universe's first, massive, blue stars in gaseous filaments, with the cosmic microwave background (CMB) at the edges. Using radio observations of the distant universe, NSF-funded researchers Judd Bowman of Arizona State University, Alan Rogers of MIT, and others discovered the influence of such early stars on primordial gas. The team inferred the stars' presence from dimming of the CMB, a result of the gaseous filaments absorbing the stars' UV light. The CMB is dimmer than expected, indicating the filaments may have been colder than expected, possibly from interactions with dark matter. Image: N.R.Fuller/National Science Foundation

Astronomers observed earliest evidence of hydrogen in the universe

MIT astronomers along with Arizona State University scientists report that they have detected faint signals of hydrogen gas from the primordial universe. The researchers have followed...
Scientists have detected a signal from the earliest stars

Scientists have detected a signal from the earliest stars

After the Big Bang, the Universe cooled and went dark for millions of years. In the darkness, gravity pulled matter together until stars formed...
