The Universe
The universe is a dynamic, ever-changing place where galaxies are dancing, merging together, and shifting appearance. Unfortunately, because these changes take millions or billions of years, telescopes can only provide snapshots, squeezed into a human lifetime. However, galaxies leave behind clues to their history and how they came to be.

The primary instrument for NASA’s Nancy Grace Roman Space Telescope is a sophisticated camera that will survey the cosmos from the outskirts of our solar system all the way out to the edge of the observable universe. Called the Wide Field Instrument, it was recently delivered to the agency’s Goddard Space Flight Center in Greenbelt, […]

The qualities and behavior of dark matter, the invisible “glue” of the universe, continue to be shrouded in mystery. Though galaxies are mostly made of dark matter, understanding how it is distributed within a galaxy offers clues to what this substance is, and how it’s relevant to a galaxy’s evolution. While computer simulations suggest dark […]

Researchers are diving into a synthetic universe to help us better understand the real one. Using supercomputers at the U.S. DOE’s (Department of Energy’s) Argonne National Laboratory in Illinois, scientists have created nearly 4 million simulated images depicting the cosmos as NASA’s Nancy Grace Roman Space Telescope and the Vera C.

Astronomers have discovered black holes ranging from a few times the Sun’s mass to tens of billions. Now a group of scientists has predicted that NASA’s Nancy Grace Roman Space Telescope could find a class of “featherweight” black holes that has so far eluded detection. Today, black holes form either when a massive star collapses […]

NASA’s Hubble Space Telescope team has released a new downloadable e-book in the Hubble Focus series, called “Hubble Focus: The Dark Universe.” This e-book highlights the mission’s recent discoveries about two mysterious components of our universe, known as dark energy — an unexplained cosmic pressure that’s speeding up the universe’s expansion — a

Some 13.8 billion years ago, the universe began with a rapid expansion we call the big bang. After this initial expansion, which lasted a fraction of a second, gravity started to slow the universe down. But the cosmos wouldn’t stay this way. Nine billion years after the universe began, its expansion started to speed up, […]
