The video explores various theories proposed by scientists about the future of the universe. It explains the Big Bang theory, which suggests that the universe began from a very small and dense region and has been expanding ever since. It...

NASA communicators describe the various ways that the agency connects with mass audiences. HWHAP Episode 233.

Former NIST physicist Kent Irwin discusses the NIST transistion edge sensor, a special integrated circuit made from superconducting materials, and how it is being used to study everything from the Big Bang to the safety of nuclear plants.

There are some mysteries that not even the greatest scientists of all time have been able to explain!

NASA has renamed its next-generation Wide Field Infrared Survey Telescope after Nancy Roman, the agency’s first chief astronomer known as the Mother of Hubble.

In this video I cover research examples going on in terms of space exploration. Main topics covered include dark energy, dark matter, black holes, pulsars, neutron st

ars, and more.

Also note there is a...

Dark Matter is one of the biggest mysteries of our universe. It makes up more than a quarter of our universe, but what is it? And how do we know it's there? Find out about dark matter in this video.

New research simulating the effects of dark energy on star formation speculates that alien life may exist in another universe.

How can scientists possibly know the age of the universe? Well, through a variety of factors, including redshift, the CMBR and more.

How is it possible that you can't see 95% of the universe? The edge of our milky way defies known physics, so physicists are using the LHC at CERN to search for Dark Matter. Dianna Cowern from Physics Girl visited CERN and spoke to...

Sound waves from the nascent universe, called baryon acoustic oscillations (BAOs), left their imprint on the cosmos by influencing galaxy distribution. Researchers have explored this imprint back to...

Scientists have discovered that a mysterious pressure dubbed "dark energy" makes up about 68 percent of the total energy content of the cosmos, but so far we don't know much more about it. Exploring the...

Scheduled to launch in the mid-2020s, the Nancy Grace Roman Space Telescope, formerly known as WFIRST, will function as Hubble’s wide-eyed cousin. While just as sensitive as Hubble's cameras, the Roman...

View "Beyond Einstein: Part II" at:Albert Einstein's theories rank among humanity's greatest achievements. They sparked the scientific revolution of the 20th Century. In their attempts to understand how space, time and matter are...

The universe is microwaving itself. A mystery signal discovered in the 1960s led to a Nobel prize. In this video, Dianna explores one of the most mysterious discoveries in physics - a constant microwave signal that seemed to be coming...

On schedule to launch in the mid-2020s, NASA’s Wide Field Infrared Survey Telescope (WFIRST) mission will help uncover some of the biggest mysteries in the cosmos. The state-of-the-art telescope on the...

NASA officially is beginning work on an astrophysics mission designed to help unlock the secrets of the universe -- the Wide Field Infrared Survey Telescope (WFIRST).



With a view 100 times bigger than that of...

WFIRST, the Wide Field InfraRed Survey Telescope, is a NASA observatory designed to settle essential questions in the areas of dark energy, exoplanets, and infrared astrophysics. The telescope has a primary mirror...

For the past 31 years, the Hubble Space Telescope has continued its important mission of uncovering the mysteries of the universe. One of those mysteries that Hubble has helped us begin to...

Hubble turned 30 this year, and it has a birthday present to share with you! Newly released Hubble images of 30 celestial objects from the Caldwell Catalog show stunning cosmic sights, many of which you can see with a backyard...

The Wide-Field Infrared Survey Telescope (WFIRST) is an upcoming space telescope designed to perform wide-field imaging and spectroscopy of the infrared sky. One of WFIRST's objectives will be looking for clues about dark...

The Nancy Grace Roman Space Telescope, formerly known as WFIRST, is an upcoming space telescope designed to perform wide-field imaging and spectroscopy of the infrared sky. One of the Roman Space Telescope's...

Scheduled to launch in the mid-2020s, the Wide Field Infrared Survey Telescope (WFIRST) will function as Hubble’s wide-eyed cousin. While just as sensitive as Hubble's cameras, WFIRST's 300-megapixel Wide Field...
