Miss Palomine reviews the letters from Mm to Zz. She shows the letter characters associated with each letter, shows the uppercase and lowercase version of each letter and describes the sound(s) each letter makes.

This video will explain the electromagnetic radiation spectrum, what it is, and how it can be used to observe space objects.

This video tutorial presents the anatomy of hand x-rays: 0:00. Intro hand x-rays 0:14. Standard hand series for x-rays 0:54. PA view (right hand) 7:16. Oblique view (right hand) 7:51. Lateral view (right hand) 8:37. In-a-Nutshell 8:43....

Astronomers say they caught a glimpse of the biggest explosion in the cosmos ever observed by X-ray and radio telescopes. <br/>

NASA reports that astronomers have detected X-rays from Uranus for the first time, using its Chandra X-ray Observatory.

Scientists reflect on XMM-Newton’s 20th anniversary. The mission, led by ESA (European Space Agency), has dramatically improved our understanding of the cosmos thanks to detailed X-ray observations. NASA funded two of its three...

Astronomers have found a novel way to explore the regions around a black hole. <br/>

Scientists using data from NASA’s Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station have discovered X-ray surges accompanying radio bursts from the pulsar in the...

On April 15, a brief burst of high-energy light swept through the solar system, triggering instruments on many NASA missions. Now, multiple international science teams conclude that the blast came from a...

Some 3.9 billion years ago in the heart of a distant galaxy, the tidal pull of a monster black hole shredded a star that wandered too close. X-rays produced in this event first reached Earth on March 28, 2011, when they were...

Astronomers using data from the European Space Agency's XMM-Newton satellite have found a long-sought X-ray signal from NGC 4151, a galaxy that contains a supermassive black hole. The discovery promises a new way to unravel what's...

Eta Carinae is a binary system containing the most luminous and massive star within 10,000 light-years. A long-term study led by astronomers at NASA's Goddard Space Flight Center in Greenbelt, Maryland, combined data from NASA...

On April 28, a supermagnetized stellar remnant known as a magnetar blasted out a simultaneous mix of X-ray and radio signals never observed before. The flare-up included the first fast radio burst (FRB) ever seen from within our Milky...

A thermonuclear blast on a pulsar called J1808 resulted in the brightest burst of X-rays seen to date by NASA's Neutron star Interior Composition Explorer (NICER) telescope. The explosion, which occurred on a pulsar...

Matter in the hearts of neutron stars – dense remnants of exploded massive stars – takes the most extreme form we can measure. Now, thanks to data from NASA’s Neutron star Interior Composition Explorer...

In 2017, NASA's Fermi Gamma-ray Space Telescope played a pivotal role in two important breakthroughs occurring just five weeks apart. But what might seem like extraordinary good luck is really the product of research,...

Scientists have reached a new frontier in our understanding of pulsars, the dense, whirling remains of exploded stars, thanks to observations from NASA’s Neutron star Interior Composition Explorer (NICER). Data...

Music: "Lost in Space" by Lars Leonhard, courtesy of artist.

This animation of supercomputer data takes you to the inner zone of the accretion disk of a stellar-mass black hole. Gas heated to 20 million degrees F...

In this video, I explain the Ottawa Ankle and Foot Rules, a set of criteria that help determine whether or not radiography is necessary prior to beginning physical therapy treatment of the ankle and foot.

A new study using data from NASA's NuSTAR space telescope suggests that the most luminous and massive stellar system within 10,000 light-years, Eta Carinae, is accelerating particles to high energies -- some of...

Scientists analyzing the first data from the Neutron Star Interior Composition Explorer (NICER) mission have found two stars that revolve around each other every 38 minutes. One of the stars in the system, called IGR...

On April 23, NASA's Swift satellite detected the strongest, hottest, and longest-lasting sequence of stellar flares ever seen from a nearby red dwarf star. The initial blast from this record-setting series of explosions...

The Christmas burst, also known as GRB 101225A, was discovered in the constellation Andromeda by Swift's Burst Alert Telescope at 1:38 p.m. EST on Dec. 25, 2010. Two very different scenarios successfully reproduce features of...

In late March 2011, NASA's Swift satellite alerted astronomers to intense and unusual high-energy flares from a new source in the constellation Draco. They soon realized that the source, which is now known as Swift J1644+57,...
