’s Wide Field Infrared Survey Telescope (WFIRST) has been named the Nancy Grace Roman Space Telescope after the agency's first Chief of Astronomy, who paved the way for space telescopes focused on the broader universe!

NASA’s Roman Space Telescope to Uncover Echoes From Early Universe

NASA’s Nancy Grace Roman Space Telescope will detect vestiges of sound waves that once rippled through the primordial cosmic sea. According to new simulations, Roman’s observations could extend these measurements into an unprobed epoch between the universe’s infancy and the present day.

In measuring how dark matter's gravity distorts space, researchers found that small-scale concentrations of dark matter in clusters produce distortions 10 times stronger than expected. This evidence is based on observations of several massive galaxy clusters by Hubble and the European Southern Observatory's Very Large Telescope (VLT) in Chile.

Hubble Makes Surprising Find in Early Universe

the formation of the first stars and galaxies in the early universe took place sooner than previously thought, suggest new Hubble results. A European team of astronomers have found no evidence of the first generation of stars, known as Population III stars, as far back as when the universe was just 500 million years old.

Slime Mold Simulations Map Dark Matter Holding Universe Together

The behavior of one of nature's humblest creatures is helping astronomers probe the largest structures in the universe. There is an uncanny resemblance between the networks single-cell slime molds create to seek food and the vast cobweb structure of filaments gravity builds to tie galaxies and clusters of galaxies together.

Using NASA's Hubble Space Telescope and a new observing technique, astronomers found dark matter forms much smaller clumps than previously known. The result confirms one of the fundamental predictions of the widely accepted "cold dark matter" theory.

Hubble Detects Smallest Known Dark Matter Clumps

Dark matter forms much smaller clumps than previously known. This result confirms one of the fundamental predictions of the widely accepted "cold dark matter" theory. All galaxies, according to this theory, form and are embedded within clouds of dark matter, a hard-to-detect form of matter making up the bulk of the universe's mass.

Where is the Universe Hiding its Missing Mass?

Astronomers have spent decades looking for something that sounds like it would be hard to miss: about a third of the "normal" matter in the Universe. New results from NASA's Chandra X-ray Observatory may have helped them locate this elusive expanse of missing matter.

NASA’s Hubble, Chandra Find Clues that May Help Identify Dark Matter

Using observations from NASA’s Hubble Space Telescope and Chandra X-ray Observatory, astronomers have found that dark matter does not slow down when colliding with itself, meaning it interacts with itself less than previously thought. Researchers say this finding narrows down the options for what this mysterious substance might be.
