This time-lapse video, obtained June 8, 2018, shows the precise choreography of NASA's Neutron star Interior Composition Explorer (NICER) as it studies pulsars and other X-ray sources from its perch aboard the International...

For the first time, NASA’s Neutron star Interior Composition Explorer (NICER) has observed the merging of multimillion-degree X-ray spots on the surface of a magnetar, a supermagnetized stellar core no larger...

Neutron stars are formed from the core of some starrs. Neutron stars generally have a radius of only around 12 km. With masses exceeding 1.4 times that of the Sun, these are some of the densest objects in the Universe. A tablespoonful of...

The Crab Nebula, created by a supernova seen nearly a thousand years ago, is one of the sky's most famous "star wrecks." For decades, most astronomers have regarded it as the steadiest beacon at X-ray energies, but data from orbiting...

What are the outer rings of a dying star? How are Supernovas created?<br/>

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....

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...

Here's just some of what we already know about neutron stars. An upcoming NASA mission will further investigate these unusual objects from the International Space Station. The Neutron star Interior Composition...

Astronomers have found a so-called black neutron star that changes our understanding of both black holes and neutron stars.

Gamma-ray bursts, or GRBs, are the most luminous and mysterious explosions in the universe. The blasts emit surges of gamma rays -- the most powerful form of light -- as well as X-rays, and they produce afterglows that...

Using data from NASA's Fermi Gamma-ray Space Telescope and other facilities, scientists have found the first gamma-ray binary in another galaxy and the most luminous one ever seen. The dual-star system, dubbed...

Astrum investigates some examples of the longest and shortest years that we know of. The differences are mind-boggling!

In late June 2013, an exceptional binary system containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed. The pulsar's radio beacon vanished, while at the same time the system...

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...

A pulsar is a neutron star that emits beams of radiation that sweep through Earth's line of sight. Like a black hole, it is an endpoint to stellar evolution. The "pulses" of high-energy radiation we see from a pulsar are due to a...

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?

Over the years, the Hubble Space Telescope has taken hundreds of images of different kinds of incredible nebulae in our universe.

A nebula is a giant cloud of dust and gas in space. There are...

A black hole is a celestial body or simply a place in space where the gravitational pull is so high that nothing, not even light can escape it. This is why it's completely black, and hence it's called a black hole. A black hole's...

Upon viewing the Stars and Galaxies video series, students will be able to do the following: Explain that our solar system is part of the Milky Way galaxy. Understand that the Milky Way galaxy is huge and contains billions of stars....

We've learned how stars form, and we've gone over some different types of stars, like main sequence stars, red giants, and white dwarfs. But a star will move between these categories over its lifetime. How does that happen, exactly? And...

This show explores the fascinating features of the universe, the different types of galaxies in our solar system and the position of our solar system in the Milky Way Galaxy. Other terminology includes: constellations, spiral galaxy,...
