Join NSF for a discussion with David Kaplan and Monica Dunford, the respective producer and featured physicist of the documentary, Particle Fever, being released in theaters around the United States this month. High school science...

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.

You've probably heard the term Dark Matter, but what is it, and how do we know it exists?

Dr. Tara Ruttley, Associate Program Scientist for the Space Station, talks about the kinds of scientific research we're doing and learning aboard the orbiting complex. Ruttley discusses why the research is important for us here on the...

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

Dark matter is a scientific mystery. We can't see or touch it. But physicists like Dan McKinsey theorize it must exist because without it, the universe would look quite different. With support from the National Science Foundation,...

Dark matter is a scientific mystery. We can't see or touch it. But physicists like Dan McKinsey theorize it must exist because, without it, the universe would look quite different.

We've gone through some of the main advancements in modern physics, which brings us to the here and now! What are physicists currently working on? One huge area of interest is developing a quantum field theory for the gravitational...

Lesson 8 (Gravitation and Orbits) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need an AP Physics 1 review before the exam? This course is for you! Exercises in this...

Two stimulating films aimed at introducing students to the wonders of the universe, its size and its origin.



How Big is the Universe?: it is impossible for the human mind to grasp just how big the universe is, but astronomer...

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...

There's more to the cosmos than meets the eye. About 80 percent of the matter in the universe is invisible to telescopes, yet its gravitational influence is manifest in the orbital speeds of stars around galaxies and in the...

Dr. Brandon Reddell discusses astrophysics, cosmology, and the science behind the Alpha Magnetic Spectrometer (AMS), an experiment looking for evidence of antimatter and dark matter in the cosmos. This is part one of a three-part series...

NASA is celebrating the Hubble Space Telescope’s 32nd birthday with a stunning look at five galaxies, a close-knit collection called the Hickson Compact Group 40.

This amazing assembly includes a giant elliptical...

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...

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 understand is...

Astronomers seem to have revealed a puzzling detail in the way dark matter behaves.

They found small, dense concentrations of dark matter that bend and magnify light much more strongly than...

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...

Every year, NASA's Goddard Space Flight Center in Greenbelt, Maryland, recruits hundreds of interns to spend the summer working on revolutionary missions featuring state-of-the-art technology. Maddy Lambert is a student...

Astronomers have sighted the outermost star the in known universe. Icarus, or LS1, is 9 billion years from Earth. Hubble saw it because of gravitational lensing, where distant star light is bent and magnified via the gravity of a passing...

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...

NASA's Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to...

Galaxies are not spinning tops. So how do stars move within them?

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...
