In this video we will begin to look at some of the key features that describe the parts our Solar System. Quite simply it is the name given to the collection of planets and other bodies that orbit a star. It is only recently by using...

What is space science? What fields does a space scientist study? In this program students will learn that space scientists work in many non-engineering fields including astrophysics, cosmochemistry, planetary geology space weather and...

Measurements of unprecedented detail returned by Japan's Hitomi satellite have allowed scientists to track the motion of X-ray-emitting gas at the heart of the Perseus cluster of galaxies for the first time. The...

On Sept. 16, NASA's Swift satellite detected a rising tide of high-energy X-rays from a source toward the center of our Milky Way galaxy. The outburst, produced by a rare X-ray nova, announced the presence of a previously...

This video looks at the characteristics of the outer planets, dwarf planets, moons and comets.

Armed with state-of-the-art supercomputer models, scientists have shown that colliding neutron stars can produce the energetic jet required for a gamma-ray burst. Earlier simulations demonstrated that mergers could make black holes....

The Gamma-ray Burst Monitor (GBM) is one of the instruments aboard the Fermi Gamma-ray Space Telescope. The GBM studies gamma-ray bursts, the most powerful explosions in the universe, as well as other flashes of gamma rays....

Three astronomers explain how Hubble acts like a time machine by detecting which galaxies are moving toward and away from us.<b<b<b<br/>r/>r/>r/>

LISA Pathfinder, a mission led by the European Space Agency (ESA) with contributions from NASA, has successfully tested a key technology needed to build a space-based observatory for detecting gravitational waves....

NASA's Hubble Space Telescope took an image of a bizarre, ghostly looking galaxy called NGC 1052-DF2 that astronomers calculate to have little to no dark matter. This is the first galaxy astronomers have discovered to be so...

Scientists have mapped the environment surrounding a black hole that is 10 times the mass of the Sun using NASA's Neutron star Interior Composition Explorer (NICER) payload aboard the International Space...

The Hubble Space Telescope captured an image of a quasar named 3C 186 that is offset from the center of its galaxy. Astronomers hypothesize that this supermassive black hole was jettisoned from the center of its galaxy by...

Combining data from NASA's Chandra X-ray Observatory with radio observations and computer simulations, scientists have found a vast wave of hot gas in the nearby Perseus galaxy cluster. Spanning some 200,000 light-years,...

The Interstellar Boundary Explorer, or IBEX, is the first mission designed to map the entire region of the boundary of our Solar System. As charged particles from the Sun, called the "solar wind," flow outward well beyond the orbits...

This video provides a brief overview of satellites, their history, and their various purposes. It explains how satellites are used for military missions, astronomical observations, navigation, and communications. By floating in space and...

A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions to billions of times the mass of the Sun, spiral...

We've talked at great length about the beginning of the universe, everything we know, and what we don't yet know. But everything that has a beginning must have an end. How will the universe end? How can we tell? When will it happen?...

NASA’s James Webb Space Telescope is folded and ready for its final suite of testing.



The James Webb Space Telescope will be the world’s premier space science observatory and will solve mysteries in our...

The Big Bang theory states that the Universe ‘began’ with a colossal explosion about 13,700 million years ago and has been expanding ever since. Here are two pieces of evidence for the Big Bang. Cosmic Microwave Background Radiation and...

Gamma-ray bursts are the most powerful explosions known in the Universe and a NASA satellite called Swift is the Gamma-ray burst look-out. Originally tasked with the mission to target 200 bursts, on April 13, 2010 Swift greatly...

Scientists using data from NASA's Fermi Gamma-ray Space Telescope have measured all the starlight produced over 90 percent of the universe's history. The analysis, which examines the gamma-ray output of distant...

LISA Pathfinder, a mission led by ESA (the European Space Agency) that included NASA contributions, successfully demonstrated technologies needed to build a future space-based gravitational wave observatory, a...

Doomed neutron stars whirl toward their demise in this animation. Gravitational waves (pale arcs) bleed away orbital energy, causing the stars to move closer together and merge. As the stars collide, some of the debris...

This video is about the lifecycle of a star but did you know that each star starts from a cloud of dust and hydrogen gas?
