The video explores the mysteries of high energy astronomy, focusing on gamma ray bursts and their origins. It discusses the evolution of our understanding of the universe, from debates about the scale of the galaxy to the discovery of...

Welcome to astrophotography. In this video I explain what astrophotography is and briefly touch on the broad concepts that make the genre so interesting and fascinating.

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...

Olber's Paradox. With so many stars in the universe, why is space black and not white with light?

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?

The James Webb Space Telescope, which launched Dec. 25, will allow us to see the farthest galaxies and better understand the origins of the Milky Way. Aaron Yung at NASA’s Goddard Space Flight Center is preparing for these historic...

When light passes through the universe and is redshifted by the expansion of space itself, how is energy conserved? The stretched light has a longer wavelength and therefore a lower energy. Is energy conserved? If so, where does it go?

At first glance, the bone-dry landscape of the Atacama Desert in Chile might seem inhospitable. But, it's prime real estate for astronomers. This desert is now home to the largest ground-based radio telescope in the world! The telescope...

NASA’s Nancy Grace Roman Space Telescope will capture the equivalent of 100 high-resolution Hubble images in a single shot, imaging large areas of the sky more than 1,000 times faster than Hubble. In several months,...

NASA's James Webb Space Telescope is heading to space to explore the universe as no telescope has before. This observatory has both cameras and spectrographs, instruments that take light apart to reveal the chemical makeup of cosmic...

The James Webb Space Telescope is going to open a new window into the universe. It will show us stars, galaxies, planets, and other objects as we’ve never seen them before. In the first of four episodes of our mini-series, we focus on...

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

Explain the process of transporting an antenna. Why are the antenna moved into different configurations? What discoveries did the scientists find recently? What do you need to know in order to work in this field?

The Very Large...

This video provides an overview of The Big Bang Theory, which is a theory about the evolution of the universe. The narrator explains how the redshift of light emitted by galaxies that are moving away from Earth provides evidence for the...

Image Coordinator Rebecca Roth discusses the process in which she chooses images to be displayed in NASA Goddard's Social Media presence.<br/>

Most large galaxies contain a giant central black hole. In an active galaxy, matter falling toward the supermassive black hole powers high-energy emissions so intense that two classes of active galaxies, quasars and blazars, rank as...

What is the universe expanding into? Where did the big bang happen?

In this video I wanted to talk about books. I show you a few words that one needs in order to talk about books in German. <b<b<b<b<b<b<b<br/>r/>r/>r/>r/>r/>r/>r/>

Astronomers at NASA's Goddard Space Flight Center in Greenbelt, Md., and the Pennsylvania State University in University Park, Pa., have used NASA's Swift satellite to create the most detailed surveys of the Large and...

A magnetic field at the center of our galaxy may be keeping a supermassive black hole at bay. <br/>

Hosted by NSF's Dena Headlee, Science Now is a weekly newscast covering some of the latest in NSF-funded innovation and advances across all areas and disciplines, from astronomy to zoology. This fast paced, news round-up reports many of...

This video is answering the question of are there different types of galaxies.

What happens when you point the Hubble Space Telescope at the darkest part of the sky for 10 consecutive days? Besides using up extremely valuable time, what would you find?
